lowering spring help

[svtmc-g]

Hey Gents. I know this is beating a dead horse BUT you all are the best info no matter what the scenario
Trying to pick some lowering springs for my car. here's my details.
-I want to go as low as possible and still have a decent ride
-I plan to have long tube headers soon after!
-who knows clearance facts assoiciated with running LT's(i.e.,you can only go___" on a 99' with LT's)
-I will also be putting on some 18x9 and 18x10 FR500's after the long tubes.
-I don't want junk springs(of course)
-let's see pics of your suggestion?
-will 1.5" drop springs and isolators together not lower that much(considering the isolators being new and stout)

Matt here are some pics of my 01 with Eibach pro kit springs. Mind you I didn't have 18's on the car and no headers. I at first put on Intrax and the car was slammed I got a much better ride with the Eibach. Didn't really have too many occasions with scraping bottom

Well, since we are using Mineral Grey '01 Cobra Coupes as guinea pigs here is my opinion. I also have the Eibach Pro-Kit on my Cobra. They are a better
ride than most and still offer handling improvements. Here is a pic with
18's on all four corners. (Sorry, track pic).

The only problem I have had
is coming home from the track with several hundred pounds of extra gear
crammed into my Cobra. If you can picture tent, camping equipment. tools,
racing gear and four extra rims and tires. With the weighted down cobra
it would rub the wheel wells on big bumps on the freeway.

I have the shorty headers and on my cobra but I don't see where the long
tubes are going to hurt your clearance. Other items on my car hang lower.

Hope this helps.

Thanks fellas! Looks great. Did you guys get new spring isolators or use your original ones? Thanks for your help!\

I kept the originals, they looked OK with no cracks or splits. New
poly isolators will definitly reduce the drop of the lowering springs, but
only 1/4".
