i have a 92 300e and i am having a hard time finding rims that will fit it. im just wondering if i could fit 20s on it? or is 18s the biggest i can fit in? also what modifications would i have to make with aftermarket rims? and to clear it the offset on a 300e is 5x112 and +35 offset right? also how wide can the rim be? i heard only 7.5 front and 8 in back? is that true? and if possible can someone help me find rims? thanks
