2" drop
 

on stock shocks, would that affect the life any? i know it starts to die faster, but are we talking in 10k miles?

Its depends on the spring rate not the drop.
IF the springs were specificly designed for the stock struts youll be fine for a long while.

these are the ebay green springs, no telling on the spring rate

I wouldn't trust my life depending on those springs if I was you, an eBay intake I can understand but springs are a little more critical. How much are they selling for? I know we all struggle putting money together for our toys but save up for Tein S-Techs and you should be satisfied. Its a good drop, the rate won't kill your struts, they're not too bouncy plus most of the time you can buy them for $160 or so with shipping. Not a bad deal ....

Are these it ... eBay Greens ?

Tien's will kill your struts they have a 50% higher spring rate then stock.
Better handeling yes but your shocks wont survive it.

Look into a set of progress group springs or gold lines.

I stand corrected ... you're right on that. Sorry for misinforming you, but I'd still advise you to stay away from the eBay ones. I guess that's just me but you can buy whatever suits your needs and budget. Good luck.

that link = yes. i am only going to have them for a short time, maybe a month or two tops. i should have all this court finished up and some moolah saved for some nice coilovers...

what are the stock spring rates on the pro?

Hope this helps ..

Also, it's my knowledge that linear springs will wear your struts faster, whereas progressive will not. I may be wrong on this, but that's what I've read on other forums ... someone please correct me if I'm wrong.

EDIT: Here's the article I read:
"There are two types of springs, progressive and linear. Progressive springs are coiled tighter at the top than the bottom, so as they compress it gets harder and harder to continue to compress them. Linear springs, the coils are the same distance apart from top to bottom. A lot of people perfer the linear springs because i think the ride can be smoother..."

great info...no wonder those ground controls blowout stock struts so quick !

350 lbs/in !!!

Chiming in. :D

Progressive springs also soak up all the little imperfections in the road better than linear ones. The coils that are more tightly wound have a lower (softer) spring-rate than the rest of the spring. Nice for the road and maybe even the touge, but on the track lInear are the way to go.

Linear springs have the same rate throughout the spring. This makes the ride a little more harsh since you feel every little bump in the road, but the controllability at the edge of traction is the payoff. That's why you won't see coilovers with progressive spring rates...they're made for peformance over ride quality.

Turn-in, braking and even acceleration are all much more predictable with linear springs. :)
