the abp eibachs are rated at 30mm now, same as the eibach sportlines i do believe, so why are the abp springs more expensive, must just be the same springs in my eyes? everyone recomends them but recently went out for a ride in an ep3 with some fitted and put me off, the ride wasnt that good and couldnt see too much of a difference i the ride hight, what other springs are people using?
