Don't give up on them just yet, have a play with the adjustment and ride height. The E92 looks soo much better with the arch gap removed....
I've lowered mine on springs only and will update the shocks at some stage but even now the ride is still pretty harsh. Its the state of the roads!! However, I will put up with it as its definitely worth it for the look!
Get some spacers, a front spoiler and M3 lip spoiler and you'll be happy as larry!
