Eibach Pro-Kit or other??
i heard of alot of people with eibacks and bilsteins lowering kits....tell me what you think please...thanks

I have no rubbing/problems turning. Their is this one spot on each side the size of a penny that rubs in the back... so just took a hammer to that. My Z06's are 18x9.5 (275/35/18) and 18x10.5 (295/35/18). Tires are Michelin Pilot Sports. I thought the fronts were 58 mm and the back were 56 mm. Not 100% sure tho.
If you drop the car I recommend getting at least: adj panhard rod, LCA relocation brackets, LCA's, and possibly shocks if you have the money. Your ET will hurt because you are throwing off the geometry of the suspension and have to make up for it. If you do everything correct you can probably end up getting more traction then stock. It also depends on what your trying to do, drag racing or autocross.

I personally feel the Eibach Prok Kit is too low in the back. The best all around look I've seen is the Hotchkis 1" drop. Just right IMHO . . . .

02WS6Bird: I haven't heard any complaints about the LG Motorsports springs, except they are usually on backorder. Does anybody have those springs here?
I think they are a 2 inch drop which looks good imo.


i think the "rear sagging" affect with the pro-kit comes from all of those people who just don't like the 'even' distribution that the pro-kit offers.
the DMS springs take the exact stance your car has stock, and lowers it about 1.3 inches. so it's not entirely on a straight line, whereas the pro-kit is. this is why the pro-kit drops the back more than the front. the DMS offers the SAME drop in the front and in the back (1.3").
some people like the straightened look, some people like the tilted stance. decide what you like before you go with either, because several things will happen:
if you have DMS springs, you'll take out the rear spacers to drop the car to the pro-kit stance,
if you have the pro-kit, you'll get new springs because you think your pro-kit "sags" in the rear,
or because once you change, you'll start a rumor about how "DMS springs didn't lower the rear any!!" or "i hate the pro-kit because the rear sags!!"
and i'm sure you can obviously see those rumors around if you read anything about either springs on just about any ls1 message board.
