Olly Hewitt would probably be the person to write that review, he used his car a LOT with one of the kits.
Specky also runs one and has done for atleast 18 months which has helped with his 60fts by keeping the wheels pointing the right way lol He did say you can visually see the difference on the rollers as cars with the kits have no wheel movement where as ones without look like the wheels are going to make a bid for freedom.
Hopefully Martin will be able to do a review as most of the kits I've recently sold are on cars that are still WIP
Cheers for the positive feedback on the quality though, the guy I use takes a lot of pride in his work.
