What type of Penske's and what are the settings if adjustable? Are they shorter shaft/body for a lowered car?

When you hit a bump in a turn does the steering wheel jerk?
Does it get worse with increasing speed, increasing bump or increasing turn rate?

Does the rear "jump" on throttle application or when steering rate is changed? Increased or Decreased?

Any oither suspension mods?

What kind of tires and what are the cold and hot pressures?

What are the alignment settings?

ahh thank you dj worm,just the man i was looking for!the penske's are non adj.(chuck mallet told me i wouldnt need the adj.'s for street duty) and they are the shorter ones.as fer steering and relating issues,it feels fine.the front end feels great.its just the rear of the car under high lateral loads squirms from side to side a bit.not much.most drivers would most likely never notice.the rear doesnt jump and straight line acceleration is great.i have 295/30-19 pilot sport 2's with i think 32-34 #'s of air pressure.stock(albeit lowered) alignment settings.just the side to side movement is a little unnerving at speed!i was thinking of raising the back of the car 1/2 ".D.J,any help/advice would be greatly appreciated.thanks,Lee
