I fitted the pro dampers and pro-kit springs. Lowered only about 15-20mm. Ride is a touch firmer and abit more 'jiggly' over very bad surface. Feels just as well damped as the OEM parts over speed bumps, none of the crashy/bouncy effect associated normally with lowered/stiffened springs. They are only less comfortable over very bad roads. My passengers all said the ride ain't as bad as they initially thought.
Cornering is definitely improved, remains alot flatter through the bends. Biggest difference for me tho, is the reduction in pitch of the car. My car has been remapped, so with OEM parts under heavy acceleration, i could feel the front lifted, thus resulting in less grip. The EIbachs seem to allow me to put the power down better. Only negative is i feel i have lost some steering feel at low speeds, tho this could be down to me needing a geometry check.
I have yet the fit the front ARB, as VW have changed the design slightly with 2008 models. SO my mechanic has asked for some new instructions, but they came back in german, so he has requested and translated version.
