Now a couple more things...
4. they said that the rims are weak and if you hit a pot hole you will damge them badly and have to replace them.
5. I don't know why they said this, giving that Paul M (kinda) disagreed with it allready, but they said that while your stopping a wheel could possibly lock up without warning. Have no clue why, on ABS system that would make sence, but not on standard 4 wheel disc brakes.
and 6. They said that the ride is very bad and is a major difference between regular 15" wheels. How bad is the ride of the car??? (especaly if I put a lowering kit on it, i.e. harder springs)
Thanks you guys you opinons have helped!
