Eibach pro kit I have an eibach pro kit with kyb shocks I plan on putting sometime soon. However I plan on running some mt e/t streets 315/40/17 on some 17x11 zr1s on the rear. Recently I've been hearing by a few pals of mine that this setup won't work without modifications to fender walls and what not. Plus that the car would be too low and scrape as well as not be able to squat properly on launch. The scraping part I'm not too worried about because its not my dd simply weekend and drag. But I want to sere if anyone has experience with a similar set up to see if any of this is true before I buy the tires.
315/35/17's most people have to do a minor amount of modification. It depends on a lot of different factors. What brand and model tire, how low you are, how your axle is currently placed, differences in chassis tolerances, etc

Yea 315/35/17's. I was mistaken. They will be micky thompsons. The eibach pro kit is said to drop the car somewhere between 1 1/2 - 2 inches from stock height the axle is curently stock might just get different gear ratio. And the chassis seems to be pretty tolerant thus far. But I will be adding lower control arms sway bars pan hard bar and maybe even some 3 point slp sub frame connectors. What modifications have most people made
Did you buy the pro kit for the LS1? or the LT1?
The LS1 kit will sag in the rear... Mine did and so did my buddies TA...
ProKit SUCKS... Bouncy and unlevel drop. i got rid of mine... Look into BMR or Stranos... Awesome height and performance...
Goodluck with swap

I agree. I hated my pro kit, not sure if they were the LT1 or LS1, they were on the car when I got it. Ditched them for some stranos. I wouldn't mind my front being just a tiny bit lower though
^^^ that is the Only Thing inane like about the Stranos... I like the front a litte lower... BMR has the Best stance IMO... Strano bars hands down tho... Work of art.

Verdad Gallardo I agree. I always think that, but then I go look at my car and the front always seems a little lower than I was originally thinking. Could use the lower perch on the konis, but it's not recommended.. Or some BMR lowering a-arms with or without the spacers, I've thought about that, and it's been done before. Just don't want to go too low since it's still a DD.
i was running the eibach pro kits 1.5 drop with stock shocks and ar ttm 17x11 in rear with nitto 555 315\35\17 drags. i had no probs whatsoever of rubbing but the ride was horrible, most likely due to stock shocks and the pro kits are known for their rough ride also. i know the mickey tompsons 315 are a little wider then my nittos so you probably will have to do the hammer mod. i have barely any room to clear at all
2) the Stranos say 1.2 lowering... And that's what they do. They dnt break in or settle anymore... BMR says 1.25 but they will settle down more after a couple hundred miles.... So yes... You can see the difference.

Well ill be putting some kyb's so hopefully thatll absorb some of the bounce I really like how the pro kit sits. A pal of mine has his in and I love it. I might just try it regardless and see how it works out I might be a moron for not listening to all of you but I already have it. Can't hurt to much to try can it?
^^^ 1st) yes pro kit was bouncy. I have Bilstien shocks... No autozone shocks... So it must be springs...

I ran kyb/pro-kit on mine and had tons of issues getting my 315s to clear (lt1 kit on an lt1 car). I rolled the fenders, added the 17" bump stops, and had the rear perfectly centered but the pass side tire still kept touching. I've heard the firebirds are just a tad wider so they don't have as much of a problem. The rear sat a little lower than the front anyway (umi stage 2 kit raised the front .3) so I replaced them with SLP eibachs/bilsteins. I was amazed at the difference between the kyb and the bilstein.

OP I have the same setup you are going with. My car is full weight and the ride isn't terrible but it could be alot better. The car scrapes alot having 3 inch full exhaust. I plan on adding a 408 so I am switching setups. I would recommend to think about what you're future plans on the car. I am going with QA1 shocks with Strano springs.

Not sure why you want to go with some non gas charged drag shocks and handling springs, that is a contradictory setup...

I have the LT1 pro kit. I love it. Its low, rides decent, and handels very well. I have been in cars with more expensive setups and just didnt see the value. I have gotten many compliments about my cars "stance".
Ill ***** my car out for people to see what the LT1 kit looks like. Stock isolators. Rear is a touch too low IMO, someday Ill add some heater hose.
