do ground controls use eibach sportlines or pros?

 

I think they use pros... but either way u can still drop the car 4"...

 

it's only 2 inches for the 240sx, which sucks!

 

Neither - they use standard race springs made by Eibach.

Eiback makes springs in just about any length / spring rate you could ever want, but you will need a coilover setup with the proper perches to use them on your car.
