prokit need camber correction?

[schyawn]

I'm planning on doing the popular prokit+agx upgrade, will this "mild drop" require any additional camber correction to get to stock specs?

[schyawn]

found some info.....seems the prokit doesn't lower the car as much as specified (1.8f,,1.6r), only maybe 3/4 to 1 inch. Is this the case with most of you using the prokit?

There should be more than enough adjustment within the factory settings for the Pro-Kit. I would say the drop is closer to 1.5 based on our experience here.

It will lower your car more than what the springs say they will. At least every spring I have ever seen settles more than the given specs. Your camber will be alright, by the way. Maybe *slightly* off, but not bad.

Just found this post.

After installing this combo on my car and doing allignment my mechanic said that my front camber is within factory limits and rear camber is -2.1% , while factory specs say the the highest it should be is -1.9%. But he said it should be alright coz most bimmers ( he specializes in them), run -2.5% rear camber from the factory.

Hope that helps.

I can scan alignment printout if you guys need it.

Well, I've got Prokits in with the AGX. And it's been sitting over a week now. I haven't measured yet (will update that), but it's certainly not the 1.8f/1.6r drop specified. It almost makes me think that perhaps Eibach measured the drop with 2 people in the car. Some rough calculations with spring rate show me that an extra 150kg could make up the extra drop. But there is some guesswork going on. I'll measure again, and measure with a couple people in the car. Either way, it's kind of dissapointing.

Grant, just to be sure, The 1.5" you say you get "based on our experience here" is with s13's right? I was going to avoid the Prokit until you said 1.5", which is the drop I wanted.

[Grant@tirerack]

Eibach lists 1.8/1.6 as an average drop. Our experience here has been closer to 1.5 on the sets we have seen installed first hand. I doubt these are going to settle. All of the Eibach springs are full compression loaded at the factory before they go out (I've done the factory tour and know this from first hand experience). These drop numbers are figured from measuring your car before the springs are put on from the center of the wheel to the fender lip, not from the ground up.

well, checking the Suspension FAQ, it seems the problem is common enough to quote a tested drop of 1"front/.75" rear. And I'm sure I'm in the same boat.

Measuring from wheel center is just to exclude the tire pressure as a factor. I've done that.

A more than 50% error in the drop (rear: 1.6" vs. .75") is more than the springs being out of manufacturing tolerances. It's an error.

I know i'm not the first person to complain about this aspect of Eibach, so I'll shut up and deal with it. I just wish someone had some good reasons for the error.

im most likely wrong but the s13 came in the base model suspension and the se/sport suspension, which was stiffer and lower. you can tell its a normall base model completely by the side view.... car looks like a damn 4x4.

maybe they took their measurements from an se... so the drop would be less.... if you had the soft and lifted base model springs then the drop would be alot more drastic. maybe they need to list the drops for the SE model AND base model. :thinker

This is probably irrelevant, but my friend has pro-kits on his s14 se and his car is as low as my se w/ sportlines. We measured and they are dead even. Course, he has had his pro-kits and tokico's on for like 3.5 years....
