i have a 320i. i'm not at all dissapointed with the amount of roll i get from her, i was just wandering, does anyone know what the roll bars are like on e30's in general. as in does each one, ie, 318 have one size, 320 have another size, 325 have another size. or is it that you have your standards, and the m3's have the thicker ones?? also, if i got thicker ones are they fairly easy to swap out? also, where would be a good place to get me some new ones?thank you for any help.
