Does anyone know what part numbers are included in the SLP Bilstein/Eibach spring/shock set, SLP part number 70002? This is for 93-97 Camaro LT1's. I am looking to see if I can get the parts cheaper seperately. I am looking for the Bilstein and Eibach part numbers.

Is the Eibach spring set number 3831.140?
Is the Bilstein front shock (strut) number BIL-B46-1913?
Is the Bilstein rear shock number BIL-B46-1914?

Thanks.

 

Bilstein and Eibach will not sell them to anyone except SLP. They are proprietary specs and protected by agreements with SLP. As to the part numbers, I'm not sure, I'll have to look tonight and see. I do know that the rear Bilsteins are just stock Bilsteins, while the fronts are the only ones that are actually valved differently.

Personally, I would keep the rear stock springs and just use some heater hose on the top coil and remove the spring perch. This will lower the rear about .5" which is about what the SLP springs lower it. Then put in standard Bilstein rears, and get part #s:
710750810 front Bilsteins Level II $96.95
720782798 front springs Level II $69.95
These are the actual Firehawk/SS replacement part #s, but I'm pretty sure you can order them now without a VIN number. You might want to call and verify that those part numbers are for the pair.

 

Well, I just purchased the Bilstein set of B46-1913 and B46-1914. Hopefully they are good shocks. I haven't gotten the Eibach's yet. I have never replaced my springs, and I am not sure if the previous owner did, but I would bet that they haven't been replaced yet. I have 125,000 miles on the car, so I figured that I should just replace the springs. I have a pretty crappy ride right now--basically any medium sized bump causes my axle to hit the bump stop on the wheel well. I know one shock I have is blown out, and I am sure the other one is on its way in the rear. Even though the shocks were cheap I probably have only had them for a couple years/20,000 miles and they are already shot. I am somewhat attributing that to the worn springs. I hope that the shocks that I am getting, which are the Bilstein HD's, mate well with the Eibach ProKit springs. Anyone have any ideas or comments on that duo?

Thanks.

 

I ran the Bilstein HDs with the Eibachs and it's a great improvement over the stock setup. You might want to talk with Sam Strano (stranoparts.com). He's a 4th Gen F-Body guru; he suggested revalved Bilsteins to go with the Eibachs; that's what I'm switching to.

 

The Bilstein HDs are really designed for the stock spring rates, but most people find they work ok with the Eibachs too. If you are serious about handling (autox or roadcourse) then you'll probably end up wanting to either get some revalved Bilsteins from Sam or some Konis.

 

I am serious about handling and cornering, but I won't be getting into Auto-X or road courses. I want better handling than stock and something that takes the bumps better than what I have now. I won't damage the Bilstein's by not having a correctly matched spring/shock pair would I?

 

They might wear out a little sooner than with stock springs, but they'll still last a good long time.

 

If I use the shock/spring set stated above, can I still use the stock rear jounce bumpers (the rubber piece that bolts to the frame that keeps the axle from hitting the frame when you hit a hard bump)? I know that the springs will lower the car about 1.25" from stock according to Eibach, so do I need to be worried about hitting those bumpers more often or do I need to cut them down? Right now I'm missing the bumper on the one side because it was used too much (with the shot shocks and bad springs) and the one side is about to fall off as well. I have already ordered another pair from Jason Cromer and they should be here soon.

Thanks again.

 

The jounce spacers are there to keep the wheel/tire from impacting the inner fender. If you cut them down any you increase the chance of this happening. Also, if you don't already have it, you need to invest in an adjustable panhard rod as lowering the car that far will most likely uncenter the rear axle fairly dramatically.
