What eibach spring kit would you guys recommend,the pro kit or the sportline for a 1985 iroc/z.I amprobably going to buy 17" or 18" wheels.this is for a street driven car and not raced.I know that the sportline kits lower the car the most,but do they bottom out thanks, Scott

 

Plenty of people run both sets. Depending on how worn out your stock springs are the pro-kit might not lower it much more but the sportlines will. One very key thing is that you will need to get a good shock/strut combo to compensate for the lowered ride hight and stiffer springs. Do a search on these boards and you will find tons of info!

 

I've got the pro-kit, and tend to drive pretty fast most of the time. My front ground effects and exhaust drag the ground a lot, especially going in and out of driveways, and parking lots and over speed bumps.

Personally, it's good that I did not get sportlines, or I'd probably be stomping the brakes ALL THE TIME to keep from knocking my front gfx or exhaust off. No way that they would have worked with my driving style. I'd rather haul butt than have to pussyfoot along, but that's just me.

It's a matter of preference and priority. If your willing to inch your way in and out of parking lots and such, get the sportlines. They do look better.

The interior roads around Dallas/Fort Worth are probably a little worse than average.

 

I've got stock springs and I drag front clip all the time... I'm sure they're sagging by now though, since they're v6 springs and I load that car full all the time.
