Hey guys I am new here and just bought a 2003 GT 4.6. Completely stock car. I want to lower it for obvious reasons. The car will not be tracked just used as a daily driver. I am going for looks and still maintain some comfort. After reading through past threads I have decided to go with Eibach lowering springs.
My question is which ones to buy for my needs Pro or Sportline?
How far can I drop the car without needing a chamber kit?
Should the rear be dropped more than the front?

Any help would be greatly appreciated.

 

When you say you still want a little comfort, that rules out the sportlines. They look GREAT, but ride rough.

The Pro Kit springs offer a decent drop and they handle great, but they don't kill the straight line traction.

At UPR, we carry the UPR/Eibach Pro springs which spec out exactly the same as Pro Kit springs, but they say UPR by Eibach on them.

You don't NEED caster camber plates with these springs, as the added negative camber improves the cornering... but if you want to minimize uneven tire wear, you'll need CC-plates to restore the factory alignment on the car.

UPR's caster camber plates start out at $135/pair (with the mf.com discount) and go up from there.

How much do the UPR/Eibach Pro springs cost?

 

The average price is around 229.00 I think. But look around. I put the Pro Kit on my '03GT, about 8 years ago. Didn't need Caster Camber Plates either. I just put on Adjustable Camber Bolts to straighten out the look, and ride. Easy install too.
