[Dorin]

Hello everyone, I just bought a mk5 gti and I wanna buy a set of lowering springs -30mm
I wanna know if they will lower the car -30mm as the gti is allready lowered with -15mm from factory. The H&R sale the same lowering springs for gti or 2..0 tdi or 1.9 tdi with standard suspension.
if anyone have photos with the car before and afther will be great. thanks
