Wobbling, bouncing around - high speed cornering

wanabgts · 08-03-2016, 05:19 PM

This is a problem with all of the cars IMO, my car had the same issue. Especially with the stock suspension. These cars have a TON of camber change throughout the suspension travel, which with low offset wheels or big tires etc can cause the rear to feel very unstable. The bumpsteer is actually pretty good for a car that has this much travel.

My track day car was scary with 315's until I got the suspension firm enough to limit the change to acceptable range. My car will go from negative 1.8* rear to +5* before I hit the limit of my downtravel.

When I put springs on my car and big front bar, the car was much more stable.

**edit****

I think have non-adjustable rear lower arms also is a problem, the longer arm length you will have with an adjustable arm when lowered would help greatly with geometry changes.
