Thanks for the replies definitively the car is a fun little rocket , today i will intall a set of vogtlant springs part 951628 they are specified to drop my car about 15mm , i dont found any member with this springs so i decided to try it.
I will install later a set of 19in wheels and i dont want to rub or have dampers leaks problems, my options for a moderate drop where H&R 28896-2 15mm drop or BMW performance springs that drop about 10mm.
i ended with vogtland because are cheaper than the bmw performance and softer than H&R all three have similar drops.
Im a little confused because in vogtland site specified 15mm drop and in the box said 15-30mm
Later i will post some pics of the result
