Hi, I have a RWD car that in some corners the rear inside wheel gets air and grinds and really stuffs up the handing, does anyone have anything to fix it (tuning or building wise)?
You didn’t mention curbs so I’m guessing it isn’t a bump/damper problem. Sometimes “stepping” on it with spring works. Lower the rear ARB and increase the rear springs a similar amount to keep the overall balance.
If it is traction rolling (too much grip for the cg height/weight/track width), less tire may be the best fix.
Good luck,
Crash
What car is it?
Possibly the rear is to stiff and axles so frigid that it’s not releasing the load of the car causing the tyre to lift up. Try softening the rear arbs and springs. Larger width tyres also would keep traction, depending on the car you’re using that is.
ok thanks guys its the abarth 131.
I am going to guess: soft rear springs + stiff ARB > to correct, stiffen rear springs and/or soften rear ARB.
3rd factor could be stiff rear bump damping, kicking the rear end up. This is normal if you drive over curbs. Some curbs, however, tends to be unrealistically nasty about it even though the curbs look relatively flat-ish, eg Long Beach - the curbs just before and after the back straight.
I think I have frixed it, it was my diff decal being too low or to low against the acel. I was 3% decal and 60% acel and it ( the inside rear) was grinding and locking. (on entry)
