Pro Streets retail between £800-£900, i must admit they are absolutely not worth that sort of money even if they are made by KW, in effect they are KW V1's, all these basic ride height only coilovers are based on the same principals, but the bigger brands do offer an edge over the budget in the way of damping and spring technology, its when get into damping adjustment etc... the money pays off.
For sure i see VAG heads running these as low as they can go, removing bump stops and the shock has little or no travel and takes the full impact on the bump/pothole or whatever, i see them removing arch liners, rolling arches, crazy camber just to get the car as low as possible and get the wheel under the arch with a huge stretch on them.
Luckily for the Cupra R its not slow and low veedub, its a lowered performance car and most of the lads on here treat it as such, lower but not to the crazy extents the other guys dubbin do, i would expect our setups to last longer than the guys slammed to the ground.
