Only a D series so trying to just get rid of the arch gap, I seen that the sportline is lower than the pro kit..I prefer the pro kit over sportline from Eibach.
But for street use, sportlines are nice.
For Track use, not to sure.
Any one know How much to the Pro's drop by front & rear?
Lowers Vehicle* 1.0" - 1.5"
