bignum Posted April 13, 2011 Share Posted April 13, 2011 I have uprated arb`s on my track car which have no adjustment, on a recent trackday at donington i noticed the car is very lively at the rear( overstearing), my question is, if i fit adjustable drop links to the rear and adjust them to slightly longer than stock will this in effect soften the rear arb thus giving more traction for the backend.

Kirk Posted April 13, 2011 Share Posted April 13, 2011 Sounds a little nuts but i think you should try it. Seeming as you run same size slicks all around disconnect your rear drop links and try it out. May not be to your taste but ive been out in a TT setup this way and its suprisingly grippy at the rear.

Chris Wilson Posted April 14, 2011 Share Posted April 14, 2011 Altering the length of ARB links will have no effect on bar stiffness, within sane limits. They are designed to enable you to do the corner weight spring height adjustments, with the bars disconnected at one end, and then re-connect them using the adjustable length to take any preload there might otherwise be, out of the bars. To advise on why you might have oversteer or traction issues I would need a LOT more info. Quote Link to comment Share on other sites More sharing options...
bignum Posted April 14, 2011 Author Share Posted April 14, 2011 Thanks chris, thats the answer i was looking for, the only difference on this car`s setup compared to my other 2x cars is the arb`s, i`m going to change them to stock bars as i`m going to the ring in july and thats not really the place for a "stiff" setup.

I will try that mate, ive certainly heard of people disconnecting the rear arb on a wet trackday, lets the rear be more independant.but brings on more understear.

Chris Wilson Posted April 14, 2011 Share Posted April 14, 2011 How much droop travel is in the rear dampers? IE, if you look where the rear tyres are relative to the top of the arch with the car sat level, then jack the back end up under the diff, how much extra clearance is there? One of the commonest causes of a twitchy rear on a track car is lack of rear droop picking up a back wheel. You could certainly carefully test the car with one end of the rear ARB disconnected, too.
