| VI This has not reached a production stage as yet, in fact I should think it is a good way off. I. The stabiliser they use adds 70% to the rate of the rear suspension in roll. Oy finds it is necessary to allow for 4" rebound. He gets better results for taking sharp corners at low speeds by over correcting The Ackermann Geometry i.e. he makes the inside wheel turn even more than usual relative to the other wheel. The coil springs are made of silico manganese Ground on external dia They are stressed to 100,000 at max bump (average stress) or 120,000 on inside of the coil. J.{Mr Johnson W.M.} We had an argument about self centering. I believe so much out of Centre point as 2 ½ " is bound to give excessive centering with 5° king pin angle transverse lean, and even with the 3 ½° transverse they are using. | ||
