What shocks to use?
Any feedback?

My car is sitting slightly lower on the pass side, I had to put 2x4's under the tires to get it off the lift
I have heard of others having problems with the pro kit sitting lower on one side or in the back, I am going to play around and see what I can do.
bilstein hd's are meant for stock spring rates because bilstein makes their hd to match the stock spring's rates. not many lowering springs have the same rate that stock springs do. most aftermarket springs are much heavier spring rates. so the high spring rates and low-spring-rate hd's are not matched precisely correct, obviously. however, there are more than enough people, me being one of them, that have a high spring rate on a bilstein hd, and have absolutely no issues whatsoever. the "hd is not meant for aftermarket springs" is theoretically correct, but to an average driver, trust me, you'll never know the difference. people say you are not supposed to run bilstein hd's with lowering springs, but they either don't know how it rides, or are car racing enthusiasts who are looking for the best handling cars. normal drivers don't notice these things.
having said that, eibachs are *almost* an exception. the pro-kit has a linear rate of 400; the sportlines linear rate is 360. stock rate (these are the front springs only that i'm talking about, the rear is not quite as important) is 292, and bilstein claims their hd's "can take 20% more than stock spring rates offer," which would put their *maximum* capability with a spring rate of around 350. so the eibachs can handle rather well with the accompanyment of the hd's, just because their spring rates are so damn low.
i have a progressive spring, and my springs don't even start at that rate (350, that is). once again, i have no issues. dampening and rebound are affected by this mismatch, but it is not something an average driver should worry about. bilstein is a good company that makes damn good shocks. increasing their "proposed" shock's spring rate handling capability by 100% or more is not going to hurt them. yes, it will hurt your handling capabilities, but not nearly enough for you to know, or worry about. many other guys on this forum are running 500-600 linear rate spring rates with hd's and have been doing so for a while - they have no issues either.
now, the original question asked about the sportlines and the shocks... if anything, do the bilstein hd's. if not, then just stick with stock shocks. the very soft sportline spring rate is not very different from stock spring rates. the decarbons will eventually die, but they'll eventually die on stock springs too. so upgrade the shocks if you can, but if you don't, it's not going to be a very big deal. sportlines are low and soft though, so keep in mind that you'll be hitting your bump stops a LOT.

Thanks for the explanation!

My brother has an 01 SS. It has a Eibach prokit and the slp bilsteins.
There is about an inch difference from driver side to passenger side. The passenger side being lower. He took the car back to the dealership and they told him that there was a 1 inch tolerance with that suspension package. They may have just been blowing smoke but thats what they told him.

If you get tire rub, then consider a PHB.
If it a street only car, suspension parts are not necessary. Buy parts to fix a problem. Buying parts randomly can cause more problems than they fix
