Handling Problem after Relocation Brackets install Just installed a set of BMR bolt on LCA relocation brackets because I had lots of wheel hop. My 98 Z is NOT lowered. My wheel hop problems are now mostly gone but on the other hand the handling quality is now reduced. As I go around corners at speed, my rear will tend to slide out.
How can I fix that? Will a bigger rear bar (Sam's 22mm or 1LE 21mm bar) solve this problem? My suspension mods are listed bellow.
Any input is greatly appreciated. Thank you!
Stock springs, Bilstein HD's, SLP bolt on SFC's,STB, poly LCA,poly PHR, Sam's 35 mm front hollow bar, stock 19mm rear bar with PU-bushings, stock 245/50 ZR 16 tires.

It's called roll oversteer, and it's why you don't run LCA's in a tail-down angle on cars that you want to handle well. My rear bar, much as I'd like to tell you it would help, will not. It will make the car looser yet.
I'd look at a better torque arm (and I can help there) in lieu of the relocation brackets. The right TA will not hurt the rear cornering grip, but can greatly help wheel-hop without the associated geometry problems you now have. Also changing to a rod-ended, no bind LCA would help as well (again I can help!). And lastly, if you used the lowest hole, move up to a higher one.

Basic suspension geometry...
when you turn, your car rolls to the outside. Your outside wheel moves up, inside wheel down. Since you have your control arms on an angle, the distance they are from the frame depends on their ride position (up, down, etc..) When your control arms are nearly flat, at ride height, they dont move in and out much with bump/rebound.
Basically, when you turn, your rear wheels are turning too.. and the more angle on the control arms, the worse the problem...
