I'm currently running factory springs with Bilstein TC sports, but found a good deal on a set of Vogtland springs designed for a 2003 GTI. Is there a big weight difference between the GTI front end and out ALH motor? I think these springs should work fine especially if their higher rate anyhow? I have 200k miles on the mounts so was thinking of ordering two new strut mounts for the front and new bump stops for the rear. Also two new spring perches for the rear. Anything else you guys think should be replaced while we're replacing the springs? Are the rear twist beam bushings hard to replace? was thinking replacing those since car has high miles? Thanks.
