I want to lower my 1989 IROC 'vert by 2.5 inches in the front and 1.5 in the back. I was going to get Eibach springs, but on their web site it states that they do not work on convertibles... I don't know where to look for good lowering springs. A pointer to where to go would be deeply appreicated.

Also, after I lower my car, I know I need to get high quality shocks. Is there anything else that is suggested to do when you lower your car 2.5 inches?


Thanks!

If you're going to drop it 2.5 inches in the front, definatly get belltech drop spindles instead of springs. Then just find someone who sells rear springs with a 1.5 inch drop. Doing spindles instead of springs keeps the geometry of the front end the same.

 

Alright, I just looked around on the net for Beltech drop spindles. I can only find spindles for lowering trucks... Can you by any chance point me in the right direction to find drop spindles for IROCs?

Thanks!

Alright! I found 'em at Summit's. They are back ordered until the 26th though...

If I do buy these spindles, do I need to do anything else besides an alignment check? Will I have to replace any other suspension parts to take the 2 inch dropped spindles? Anyone know where I can find rear lowering springs for my IROC? Gotta get that aggressive stance!!!

BTW, I know this may sound like a stupid question... my handling will improve with dropped spindles up front and lowering springs in the rear? Or will my car develop a weird handling attitude since it's lowered via spindles in the front and springs in the rear? I will be getting SFC's along with the dropping equipment to remove the slinky feeling.


Thanks!!!

One thing you will need are Skinnies up front! 2.5" is a LOT of drop for an IROC that is already fairly low. I dropped my 'vert 1.5" with springs and it is already pretty low. Another inch and I couldn't have driven anywhere!!

Anyways, you will need an adjustable panhard rod to keep your rear end straight (in the center) when you lower it.

Dang... I just went outside to measure the ground clearance and fender gap. It has approx 2.5 inches of fender gap. The ground effects are 6 inches off the ground. The underbody components are 4.5-5 inches off the ground. The air dam is three inches off the ground.

Now... I want to get rid of the fender gap and have the look of the wheel being part of the car instead of floating over a set of wheels. I really want to drop it. In order to achieve the look I want, it will have to be a 2 inch drop. But from the measurements that I have taken, it would be suicide for my car. The underbody will only have a clearance of 2.5-3 inches from the road. The stuff under there will be crushed by speed bumps, sharp inclines, and curbs.

How are you all doing with those 2 inch drops? Is driving tough on the car after you dropped it? I guess I'll just have to accept a 1.5 inch drop.

Will I have to change anything else besides springs for a 1.5 drop? Trying to figure out the total cost before I plunge the money in.

Thanks!

You will still need to get an adjustable panhard rod, or your rear end will not be centered!

The Eibach Pro-Kit are what I used for my 90 'vert. They worked fine.

One thing that I have seen people do to get rid of the wheel gap, along with lowering springs, is to put on larger wheels at the same time.

I know that you probably do not want to do that, but that's just what I have seen.

Yeah, I thought about bigger rims to take up some fender gap, but it's pretty expensive...

Hey, lonsal... how much fender gap do you have after you put on the Eibach Pro-kit? is there room for more drop or it's pretty tight with those springs? I looked at your webpage, but I could not really see the fender gap since it's dark in that area.

I just stumbled across Intrax spings... they state that they will drop my front by 2" and rear by 1.8"... They also openly state that it will work work with convertible V8 model Camaros. I'm considering these since they are the only ones that I can find that are straight forward about the application on convertible models. It is also cheaper than Eibach Pro/sport lines.


Keep them coming folks!

ASC took delivery of T-Top optioned coupes and just cut off the T to make a convertible. All mod items that work on a coupe will work on a convertible as long as it does not affect the underside convertible rocker panel reinforcements. Subframe connectors weld into that area where the convertible reinforcements are.

Front and rear springs, shocks, etc. are all the same for coupes and convertibles. The convertibles actually weigh more than coupes before the mod from coupe to convertible.

Steve, all true. But the 'verts got different springs stock in the rear than coupes because of that extra weight. Some aftermarket spring mfg's (Jamex for one) also have a different spring for the rear of the 'verts than they supply for the coupes as well. Eibach uses the same for either application. Measurements: (taken at the centerline of the rim) Front: 26-1/4" ground to fender lip, 1-1/8" (or two fingers) top of tire to lip. Rear: 26-3/8" ground to lip, 1-1/2" (or two and a half fingers) top of tire to lip. Also 1 week old Falken's front with well worn Falken's rear.
