Thanks for your reply Red.

Well I'm not sure how reasonable it is but the fronts I got on Amazon p/n 505-548 at $237.52 each, and the rears I'm going to get on Rock auto because they are cheaper than Amazon even with prime free shipping, $220.49x2 vs $205.79x2 + shipping. That is about what I have seen other members pay. I wish it we're cheaper but I'm not looking to buy anymore ACDELCO stuff for my car unless it's a bezel or something, and kyb doesn't make monotubes. I love German engineering.

So yes I'm looking into the GXP springs as you mentioned...on RockAuto the same springs are listed for the 5.3L and the 3.8L...but from what I have read the GXP had different springs on it than the other trims...as seen in the very old thread on clubgp.com "**The Official GXP Wannabe Suspension & Brake Upgrade Thread***" http://www.clubgp.com/newforum/tm.as...mode=1&smode=1

Should I go with the OEM Moogs springs 2x CC670 + 2x CC697 and move on?
Should I go with Moog mounts too?


Thanks,

Stef
