Tony Posted March 29, 2018 Report Share Posted March 29, 2018 Not your usual horror other than a horror to find.... The car in question is a TVR which are fundamentally hand built and open to human error. The owner has had a nightmare trying to find an intermittent knock from the rear of the car, all the usual complainants replaced including all the bushings, the drive train couplings, but the knock remained. My job was to calibrate the chassis after all the work and since each TVR chassis is different the settings are unique to that car. So while i was analysing the rear wheels camber curve i found the knock. A simple reason with a simple fix...If your looking in the right direction. As you can see the coils helix is catching the anti-roll bar bracket. A solution would be to shim the lower coil mount or re-shape the bracket. I think this was missed because the sound was so pronounced people were looking for a larger reason hence why this got overlooked. Quote Link to comment Share on other sites More sharing options...
Rich Posted March 29, 2018 Report Share Posted March 29, 2018 Is the suspension standard? It's strange the coils are that close they can touch. Quote Link to comment Share on other sites More sharing options...
liner33 Posted March 29, 2018 Report Share Posted March 29, 2018 Never seen the attraction of TVR's if i wanted a kit car I'd build one myself 1 Quote Link to comment Share on other sites More sharing options...
Tony Posted March 29, 2018 Author Report Share Posted March 29, 2018 Yes Rich they are Bilstiens and the spacing between the helix is natural. Thing is these coils would have a very high rate so there's little compression. Problem is where they are placed and as Liner says TVR is technically a kit car so no two are the same.
