Rear end jumping
 
Hi all, this issue drives me crazy help me figure it out

When hard cornering instead of power slide my rear end starts to jump what could cause it?

I have tein coilovers, spl camber arms, hochkins sway bars (rear set on soft), spl endlinks 0 preload, car is corner balanced.

spring rates? are you set to full soft?

I had some wheel hops in the past on my g, stiffening my dampening solved my problem

but under HEAVY cornering I can only imagine the sway bars to have some influence in that, (car will lean, and maybe lift or angle the other wheel too at extremes?)

^ maybe your tires are too sticky for your suspension

Or not enough grip.
Or inconsistent grip.

I'd blame the Hotchkis sway bars, followed closely by your coilover setting. If you're too stiff or slammed, then your rear will jump all over.

This may be it. OP, how low are you? You may be at the limit of suspension travel if you're slammed.
