"After reading all the available information about the CG-Lock, I still wondered whether this small device could provide all the benefits listed.

Well, the simple answer is YES IT DOES!

Since installing and using the CG-Lock in my Mondeo, not only am I kept firmly in my driving seat, it has improved my driving pleasure (something that is rare in today’s world of driving in the UK) and it has improved my back posture and consequently, I no longer suffer back pain after extended driving. I would unreservedly recommend the CG-Lock to both friends and family, and I plan to purchase several more so that I can equip my vehicle fully, and pass on its benefits to all passengers in the vehicle."

"I am writing to tell you of the amazing difference I found in the control over my car while driving with the CG-Lock fitted.

I have been thinking of fitting an after market seats in the front of my M3 for track days and blasts to the ‘Ring’. This is no longer a requirement, as with the CG-Lock fitted and adjusted as you explain in the fitting instructions, I am held in the correct posture in my standard fit sports seats. After reading the magazine reviews and feed back from your site and others, I was still sceptical, but now I am a 100% convert. I agree any car that has any sporting tendencies should have these fitted as standard. I feel on any trackday, all cars entered should be fitted with CG-Locks to at least the drivers seat belt, as the driver can concentrate on what is going on outside the car, rather that struggling to stay put inside it.

I have always suffered from back ache after a long journey, this weekend after returning from the WTCC meeting at Brands Hatch and the 200 mile round trip involved, not a sign of back ache. I noticed at all times I had great posture without having to regularly lift myself in the seat to regain my posture.

My car is a 1995 BMW M3 Saloon which I have kept as near as standard as possible and with the CG-Locks fitted this will still be possible. I think the standard leather sports seat look far better than any after market seats. With the CG-Locks fitted, I and the front seat passenger can keep our posture allowing us to stay far more alert and concentrated on the drive, as back ache and movement in the seat are taken care of by the CG-Lock."

"I purchased the CG lock as I didn’t want the hassle and mess with fitting harness’s as I use the car everyday for work, so I purchased and fitted the CG lock. I now feel a LOT more stable in the car round the track (including the Nordschleife, Nurburgring!), I can’t believe the difference it makes and I can’t recommend it enough."

"Easy to fit and even easier to use, the CG-Lock is a must for any track day enthusiast with inertia type seat belts"

"I’ll keep this short and sweet..the CG-Lock is a must!! Having completed 8 laps on The ‘Ring with it fitted, it really does do what it “says on the can”! The hips are firmly held in place allowing for a more stable driving position thus a better drive without having to brace the body using the steering wheel in fast bends. The steering wheel isn’t an extra which aids body stability, the CG-Lock gives the driver the opportunity to drive the car!!"

"I’ve only driven a short distance so far with it fitted but notice the positive results already, makes you feel part of the seat when you throw the car about through some twisty roads. I feel that this simple but effective bit of kit is a must for performance car drivers."

"5 minutes to read/digest the well written instructions. Fitted in minutes. Pulled the CG-Lock tight as instructed and the 1st impressions as I set off down the road was not sure what all the fuss is about. Then I went on a sprited drive down some private twisty roads. Now I know what all the fuss is about. Fantastic. Holds you firm in the seat and no movement from the hips."

"I finally got out with a CG-Lock at the weekend in my 350z. What a difference! The car I knew and loved suddenly felt like a blunt instrument. The already detailed steering feel came alive and it was as if the whole balance of the car changed! I could corner harder, drift longer and I even found the position seating MORE comfortable on my lower back! While it’s no 6 point harness it’s better than I could have imagined."

"I had 2 CG-Locks fitted in the car in no more than 10 minutes.

"Extremely happy with the device and it was of much interest to many of the other drivers I showed it to. It really completed a very successful and enjoyable days driving."

"It’s very good on the twisties. Well worth having."

"Excellent… the CG-Locks work fantastic. Even though I have sports seats and high bolsters at the sides the addition of the CG-Lock works perfectly together. The CG-Lock pulls you into the seat making you feel very secure and safe, because you still have full movement of the upper part of your body you don’t feel trapped as you would with a full race harness. I have also fitted one to the passenger seatbelt, so when things start getting enthusiastic around the corners and twisty bits (always within the law mind) passengers comfort isn’t spoilt so they have as much fun as the driver, to which in my mind is important as driving should be fun. With the CG-Locks holding you in place driving is even more fun. I didn’t want to spoil the look of the interior with a race harness, and the CG-Locks are very discreet but an excellent piece of kit.

"I am lucky enough to own a Porsche 993RS which makes the occasional foray into the track. After toying with purchasing some harnesses for the car, I decided to invest in a CG-Lock. After a recent trackday at Bedford Autodrome I can happily report that the product does improve driver comfort on track, and also on the public highway. I would be very happy to recommend the product to others."

"Well recommended, it really does make a difference for spirited driving. After having tried it, I won’t be without it on the nurburgring."

"I bought a CG-Lock at Rallyday Castle Combe. My car is my dream ride, a 911 Turbo (996 model), which is absolutely sensational in every way… …except one: the (optional) "sports" seats actually provide remarkably little lateral support and after 2 years of hanging on to the steering wheel in corners and increasing reticence to enjoy the car’s performance as a result, I had begun to look around for replacement seats. This was going to be a very expensive exercise, but absolutely necessary, such was the ruinous effect of these inadequate seats.On seeing the CG-Lock advertised I immediately realised that for a very small outlay, this may just cure the Achilles Heel of my car."

"I love mine and use it on every trip, really holds me in and you can really feel it working in the twisties. It just makes me feel secure. I have heavy duty anti roll bars on my car so it corners flat and the GC lock really helps to keep me pinned, I cant find enough corners to go round."

"I have a device called a CG Lock fitted to my Merc, and I have to say that it has been somewhat revelatory. I am not quite sure about the claim ( http://www.cg-lock.co.uk/ ) that this is ‘like a harness’, but the simple act of locking 80% of your weight in position (legs, trunk) doesn’t half make a spirited drive easier, with a more reliable pivot for the arms/ shoulders (which are unrestrained, as that part of the inertia system works unimpeded). It is remarkably simple in use, and very reassuring. Using it loose now (effectively ‘off’) feels distinctly odd.

"It really is excellent. Just tighten it up when you want to give it some beans and you’ll find yourself not bracing round the corners."

"All I can say is I wish I had thought of it! It stops you having to brace yourself when cornering at speed and means you can concentrate on the track and any hazard that may appear (spinning EVO’s). I recommend anyone planning to do any track work with only standard seat belts installed should get one."

"I have very deep Recaros so the CG Locks’ main job is to keep me in place vertically which has worked great as I tried it on a bumpy B road and I no longer feel like I’m floating about in a Russian space station"

"I fitted the CG-Lock to my 1998 M3 last week in anticipation of the BMW CCA Driving School at Thunderhill Raceway in Willows, CA. Installation was simple from the clear instructions and took only a few minutes (even with an interruption from my wife). Use of the CG-Lock is equally simple and intuitive, another good thing because I did not have a chance to test the application before I headed to the track. I followed the suggestion in the instructions and used the CG-Lock at slightly less than absolute tightness for the 2+ hour drive to the track. The increased stability was a benefit even for highway driving.

"I put (the CG-Lock) in my pickup for a trip to the west side of Vancouver Island to go fishing. Now that was fun. Without my ass sliding around it made the trip way more fun since the pickup is built to play like a sports car. Then when I got home I went to a Porsche track day to play & teach. It did add to the control of the car since my butt was planted and I could shift & brake without having to brace myself. I normally have a five point harness on in the car but opted to use the CG-Lock. By adding the dimension of body control by the CG-Lock I felt comfortable under hard braking & fast car maneuvers. Thank you for a great product. Now I need to get one for the pickup full time. And, I will be recommending them to the drivers I teach. Especially the Corvette owners, since their seat belts are so lame. Thanks again."

"I had driven the car up from Atlanta, and the first thing I noticed about the product was the lack of fatigue I experienced on the ride home. I see a chiropractor for lower back issues, and my back did not bother me at all during the ride home. I have now logged over 5000 road miles with the CG-Lock with similar results. I attribute this to maintaining better posture over the course of these long trips as my hips do not slide forward, causing me to slouch in the seat.

“Finally had a chance to try (the CG-Lock) just this past weekend. Installation was very easy since I switched it between two cars an M3 and a Mazda RX. Took about 8 minutes to figure it out the first time and about thirty seconds switching between cars. Pretty intuitive even without the instructions. M3 has leather seats. Previously always a problem with my butt slipping on the tracks. Nice secure feeling making not only heal and toe easier but clutch work much less straining since I didn’t have to constantly brace myself on every turn. Surprisingly, it made the biggest difference in the Mazda. The Mazda has cloth covered "racing" type aftermarket seats, so I thought slipping would be much less. Without the CG-Lock, the Mazda was just a little better than the M3 in terms of bracing myself. However with the GC-lock, the Mazda came alive. The combo of racier cloth seats with a tight belt made the learning curve of going faster drop much more precipitously in the Mazda than the M3. The cars are surprisingly pretty evenly matched due to the mods on the Mazda, however the feel of each is night and day different. The Mazda was twitchy where the M3 was smooth. This translated to a great need for a seat of the pants feel that the CG-lock amplified. If you don’t have or want full belts, then the CG-Lock is a must. This should be on top of the Tuner Crowd’s list of top "must haves" way before that trick muffler. Great product that gives a huge bang for the buck in helping you drive fast and IN CONTROL.”

"I was at Buttonwillow Raceway this past weekend. I’ve been tracking my car at this same track for four years now although about three years ago I installed a set of Scroth four point harnesses for both passenger and driver. I tried the CG Lock and found it quite easy to install and use. I installed it in a matter of seconds just before the instructor orientation laps. It was a good thing too because that morning I didn’t feel like setting up my Scroth harnesses. In fact, once I got the CG Lock cinched down and was on track, I found that I didn’t really need to use the harnesses! I ended up using the CG Lock all weekend. Great product!"

"I’m a real track day animal and this CG-Lock is straight from drivers heaven. After running my M3 with its standard running gear I decided it was time for something a little more interesting. The powerplant from an 850i was the chosen dish of the day. This has given me the ultimate weapon at track events. The only real downside has been that as its my everyday ride I can’t fit harnesses, they are just not practical for me. Dean supplied me with a complimentary CG-Lock to try out on the circuit and I honestly couldn’t believe how different it felt having some decent support. I will no longer go home with the obligatory bruises on my left knee and right elbow from a hard day at the races. Very trick!!"

"I got my CG-Lock at Rockingham Raceway during the 30th birthday celebrations for the BMW E30. Having run the car for most of the morning using the standard seatbelt, I had become very aware of the amount of sliding around I was doing on the not over supportive leather seats. After just a few minutes and a few pounds later I was held in the seat by this new CG-Lock lapbelt system, it is worth its weight in gold as far as I’m concerned. Both myself and my son felt much more in control of what we where doing on the circuit and will be recommending this neat accessory to our track day colleagues from now on."

"A funny thing happened on the way back from a track day… my M3 and I hit a patch of ice on the road and ended up shiny side down in a ditch. The shoulder belt was loose, but my “CG-Lock”ed lap belt held me tightly in the seat, ass over teakettle. You say the CG-Lock is not a “safety device” but it sure helped to be held securely while I was figuring out how to get out of the car. Thanks!"

"They’re fantastic - especially if you change cars regularly and don’t want to fit harnesses!! I hit the barrier in a VI RS at a tremendous speed and rolled it at Oulton Park. The car twisted / turned and rolled like a rollercoaster, ending up some 200 mts from the impact. As you can see the roof was dented in by quite a few inches just where my head was. Luckily I had the CG-Lock on, which held me firmly into the seat while the car was rolling - especially as i’m 6′ 4". I’m lucky to have walked away with cuts & bruises but i’m sure I would have had much worse injuries had it not been for the CG-Lock."
