On the Eibach Sportline you need to cut your front stock bumpstop about 40 mm which is about half the size of stock.
Also the 5th Gen fender for the front is higher so even if you lower your car evenly for example 1.5" front and rear
the rear gap will be smaller then the front gap. That is what I was told before I got my car lowered. And that is why I picked the Sportline it lowered the front about .1-.2" lower then the rear to compensate for the higher front fender.
This first picture is quite old. But see how the front is lower. Which I like.
More recent picture after alot of settling. Its even but the front is still a bit lower then the rear when I sit in in and the fuel tank is not full which is good. With a full fuel tank it sits evenly.
