I recently bought the intrax lowering springs with illumina 2's and while I was removing the old suspension, I found that the current springs are eibach. Once I installed the springs it actually raised the car. Currently the engine is out so i am wondering if I should stay with the intrax, and once i install the engine it will lower it down or should i stick with the eibach which have a manufacture date of 1998. What do you guyz think?
