So i have a brand new Set of Eibach lowering springs (sportline) and was wondering if the Bilstein HD shocks would work well with them also have a single side Adjustable Pan hard bar.

if there is anything else i need with this please give input im very new to this..

thanks

NO,i did not like that combo.......
i did sportlines & new H-D bilsteins on my 2000 ss & it road like shyt......
rear end was to low.

check your options on shocks since you already have the springs.

good luck!

Have you since then taken them off?

If so what did u replace them with?

Also that's my problem trying to figure out some affordable shocks that I can use with these springs.

we have put sportlines on 2 cars.......the rear springs are weak,both cars sagged just a tad in the rear.

my 2000 actually had staggered rims toooo & it was not enough.
17" in front & 18" in the rear,i forget the tire size.....but i had the biggest i could fit on there.

my nephews 2001 had 17" all around & his did the same thing,i forget what he changed his springs too?

Sportlines are just a bad combination of ride height + springrate. For some reason they have lower rates than their higher prokit set. It should be the other way around.

Stock springs and loose the spacer for the rear. Stock frt. Single Konis or Stano valved Bilstiens. New adjustable rear control arms and an adj. torque arm.

No the Bilstein HD shocks won't help you much, and should you do go for the Bilstein's they'll blow out in about 30K miles max.

And it's not that the Bilstein's are bad shocks, they're a better street shock than just about anything out there but they are designed for stock springs, and they will never be able to operate the way they were designed to do with stock ride height so they will end up blowing out on you.

those sportlines, I have no idea why Eibach offered those things, as all they offer is a great lowered look.

Period.

don't expect a good ride at all, not matter what shocks you get as they're too damn low and on top of that the spring rates are softer than just about everything out there so you will continue to bottom out.

If anything, only the Koni's would give you a decent ride cuz you can adjust them to be stiffer so that you can prevent your rear axle from bouncing but even then the rear is so low that your axle will be inches away from hitting the bumpstops.

good luck!
