I had Eibachs and Konis in my 98 SVT but after about 3 years (just recently) it started to clang and bang as it had slowly been losing fluid in most of the struts. I usually kept it about 25% up from the softest setting. Anyway I didnt want the Konis again and went with the Bat kit as I found the Eibachs just too low.

I have them in and I have to say that I'm dissapointed. It feels like the car is 100% bone stock, just 1" lower. Maybe thats how it should be but its not sporty in the least. In fact, the fronts feel softer than the rears. When I hit a big dip on the highway, the front tends to wallow around more than the rear. I also replaced strut mounts at the same time to be sure as well as all end links.

Anyway if you want bone stock and a tad lower, then the Bat kit is great but I think if you expect any performance, go with something else.
