hey guy, wondering if you could help me understand some of the stuff going on with my suspension.

First off what I have done
-summit lowering springs
-kyb gr2 shocks/struts
-lakewood lcas
-umi adj phb
-stock sway bars with poly bushings
-sfc
-new steering
-wonderbar
-edelbrock stb
-hunter motorsports strut mounts

Things I know I need to correct

-lcas are higher on axle side
-phb is 10" off the ground on chassis side and 10 3/4" on axle side


Problems I am experiencing

-on my first recent auto x experience I am going wide(understeering?) coming out of corners, can this be remedied by a larger rear sway bar?

- on the highway when I hit a bump it feels like the drivers side rear jumps up, causing it to bobble, roll, skip around side to side(jacking?). Is this caused by the uneven phb?

Thanks for any input!

what size and kind of tires are you running? You are probably ok with the phb where it is, for now. do you have any info on what spring rate the summit springs are? they may not be ideal...dunno.
you seem to question whether its understeer you are experiencing. I assume that its not hanging the rear end out which would be "loose" or "oversteer". If its not turning through the corner with steering input, then yes, that is understeer or "tight". Do you notice this more when turning a certain direction? if so, this could be do to the phb's position.
LCARBs will probably make it tend toward a tight condition but really should be used to correct the geometry. A spring change may be needed to correct the handling. Depending on the severity of the "understeer" condition, you may or may not help it with a sway bar change.
Got a link to these Hunter Motorsports strut mounts?

i am running bridgestone potenzas g007's 245 50 16. I don't know the summit spring rates.

Then understeer is worse when turning right.

Before I troubleshoot suspension tuning I always double check the basics. Are all pivot points on the rear moving freely? Nothing binding, rubbing, hitting?
I know it sounds simple but you can end up chasing your tail- been there done that.....
