I have a 2005 Roadster. I was wondering what the "normal from the factory" rear thrust angle measurement is for a Roadster. Is it possible to change the setting?
Why do you ask?
As regards the use of rear axle anti-tramp bars, on a Morgan these are used to prevent the rear leaf springs 'winding up' when accelerating quickly from a standstill and partularly noticeable when sticky tyres are used and race conditions. Under such circumstances, the springs allow the axle to rotate on its axis with the forces changing the spring shape from a 'flat U' to that of a 'flat S'. With axles fitted with a limited slip differential (LSD) this action will also occur side to side as each wheel grips then breaks traction. Definitely not good for differentials!
