I was planning on the purchase of new lowering springs and was wondering should I go with the 1" bmr kit or the 1.5" eibach kit? I'm adding headers soon and I'm concerned with clearence problems, does anyone have any input???

 

OK, first, what's your car?
Second, what headers are you considering? Realize that lowering your car will significantly cut the clearance between ground and header collectors/downpipes. It's a matter of what type of headers your'e getting, i.e., full, mids or shorties.

 

save your money from the springs and get better headers.

 

I have a 35th SS and I was planning on getting the slp headers.

 

Well now, now we're talkin...I've got those very same headers on my car!!
..and a set of DMS springs front and back. 1 1/2" lowered front, 1 3/4" lowered rear, and they do bang some. Speedbumps, sharply angled driveways are the worst. No puncturing (so far), but the downpipe's got some scratches on it, as well as the Random cats. Also went with the SLP 3" y-pipe, but no probs there. I would recommend not going as low as I did, should take care of your clearance problems.
