Shock and Spring upgrade 101....Come in... OK Guys I have a '99 T/A M6 that I lowered with only springs (Eibach Pro) about two years (15K miles) ago. I am pretty sure that my stock shocks are now toast. So here are the 101 questions:
1. Should the shocks always be replaced with new lowering springs?
2. Should you always buy shocks that are valved for your specific springs?
3. By running these Prokit springs with stock shocks did I prematurely wear out my stock shocks? Do you think it has hurt the Eibach springs any?
I have now purchased a set of SLP Bilstein shocks to replace the stockers, so do I need to buy SLP Bilstein specific Eibachs or can I stick with my Eibach pro-kit? Will the pro-kit prematurely wear out the SLP Bilsteins also?
**Problems I am having with my current setup. Front is VERY low. rear squats VERY hard on shifts (enough to bang the hell out of the bumpstops that I have shaved 1" off of already). Honestly the car looks very nice at this height but I plan to add FLP LT's in the next month or so and I need about annother .5" of Ground clearance for reassurance.
Any comments or advice for where I should go from here? Am I going to be OK with Eibachs prokit and SLP bilsteins or do I need to Go with some SLP Eibachs now?
TIA,
-Nick

Re: Shock and Spring upgrade 101....Come in... Honestly, I doubt you've "toasted" your shocks. It sounds as though you and I have suffered from the same "sag" that Eibachs are getting a reputation for.
I replaced my Eibach Pros with G2 Super Springs about a year ago. Everything is as it was since day one with the G2s.
I had my Eibachs about 18 months and 30K miles.
FYI, I installed the Bilstein HDs when I installed my Eibachs and now have the same shocks on with the G2 Supers.
Re-valving the shocks is a thing that racers do to get consistant and maximum shock performance

Re: Shock and Spring upgrade 101....Come in... The car is definately about .5" lower now than it was. And the suspension is tooo soooft. My car only makes 305 RWHP and on the 2-3 shift the rear suspension bottoms out. I have G2 Adj PHB LCA's and Relo brackets.
What would you reccomend I do. I feel that G2's springs are going to be too low for my FLP LT's. How about Hypercoils that LGM sells? Maybe Try eibachs again but this time go with SLP's version?
Is it Very important for the Shocks to be Valved for your specific Spring???
TIA,

Re-valving is a thing that racers do to get maximum performance from their shocks. It's not a bad thing to do, but might be overkill for a street only car. JMHO

Re: Shock and Spring upgrade 101....Come in... I would suggest the HD Bilsteins for your springs, but the softer SLP Eibachs will work fine.
Ride height is not affected by shocks, springs support the weight, shocks resist sudden suspension movement or oscillation (aka dampers).

Re: Shock and Spring upgrade 101....Come in... The Hypercoils will drop the car 1.25" all the way around vs. the G2 springs with a 1.5" drop in the front and 1 5/8" drop in the rear. The Hypercoils won't be quite as stiff as the G2 springs, and they will give added ground clearance. The FLP's tuck up really nice under the car, so you would still have a nice amount of room under the car with the Hypercoils. The SLP Bilsteins should work just fine with the Hypercoils. We have the HD Bilsteins in stock if you'd like to give them a shot. As expected, they'll be a little more aggressive than the SLP units.
