Default Who tell you SLP Bilstein Shocks & Eibach Springs front height then the back is WRONG

I read couple thread where peoples complaint that their, SLP Bilstein Shocks & Eibach Springs front is taller then the back, I dont know about it, but I install that packet on my 97 z28, and front and back is look exactly the same. They do drop 1 inch like they ad. I dont know if my lt1 is iron block, it heavy these those ls1 aluminum block ? that why those front spring is sag down ? I post pix when rains is stop again.

So to clarify.... you think the ride height for Eibachs works good for your car in the front? Are you using the LT1 Eibach prokit?

I use the SLP Bilstein Shocks & Eibach Springs, it not LT1 Eiback prokit, I use what ever spring that come with SLP Bilstein kit. It been few week, and I put roughly over 300 miles, both front and rear is same height. Like I say before I think the front is sag down cause LT1 engine is way heavy then LS1 engine. That properly why.

I installed the SLP combo about 4 or 5 years ago and was pleased with the handling/ ride improvement over stock. At the time the $1200 CDN seemed ok but obviously for about the same money there is much better available (strano esp). There was a 1 inch drop at each corner post install with the front being slightly higher even then. I wondered if the aluminum engine was the culprit(less weight) but the rear has dropped a little more since. Also, that option was a factory option that must adhere to many standards including (in Canada) minimum bumper height to be legal. Police do break out the tape measure and impound vehicles for this at times! The last GTO was not offered here , sadly, due to bumper height non-compliance from what I read(?). Was the front designed to be higher to comply to many markets? Did SLP make one spring for LT1 & LS1 to save $? Definitely the rear springs sag with Eibach stuff, incl SLP/Eibach. Perhaps a piece of rubber on the bottom perch could alleviate this? Anyone try to RAISE the rear this way?

I'm completely confused...what exactly are you asking? It's kind of hard to decipher exactly what you're trying to ask.

What he said... not trying to be rude. I just don't understand the point that the OP is trying to make.

I would imagine a set of air bags in the springs would help too. That way, you could adjust the preload on the springs where you need to as well as raise the ride height. Kind of a gumpass fix. But cheap and effective.

give it time. springs are not going to sag in a short time give it a couple years and then you will be where my friends at. his 02 with the slp ultra z suspension with the stage 2 springs sags and the car only has 12k on it so just keep that in the back of your head.

The SLP Bilstein kit that they currently sell is the same stuff as the 96-00 OEM Bilstein installed package. The 01-02 SS and Hawks if ordered with the Bilstein package recieved softer springs which have been known to sag. SLP no longer sells the 01-02 specific setup.

Exactly!! I'm still looking at the pictures trying to figure out what he's complaining about. I see very little difference between the front and rear, and the driver and passenger side.

Also, taking pictures with your mustang in the picture doesn't help. All you're doing is moving further away from your car. Try explaining what exactly you're complaining about, then take a picture of just the camaro pointing out the issue.

I honestly think you need to slow down when you type, because I'm really having a hard time reading your sentences.

he is complaining about is that everyone who has had slp springs says that they sag. and that he just put some on and they dont sag. well i just put a prokit on my 98 and guess what it dosnt sag either but the issue is it will sag as will the slp springs. once he starts to put some real milage and a few years on them the back will sit lower then the front.

I have a pro-kit, and the springs have been on there for approximately 45K miles, and it doesn't sag.

I guess I have never heard that either springs sag.

My stock SLP Eibach springs sagged like crazy in the rear, so yes the front did sit higher. I eventually changed the rear springs because they were pretty much riding on the bump stops. This is with 20k miles on the car, it was about 4 years old
