Right i have bilstein magnesium coil overs fitted on the front of my car with tarmac springs and i also have the same but gravel springs for the rear but i havent fitted these as i have a few small bits missing my question is this would i be better off to sell this complete set up and put some other coil overs on my car as these are more track day not road set up and if so which coil overs are the ones to go for
