I have Ground control coil overs, fronts are 375lbs and rears are 550lbs. I would suggest to go heavier in the fronts though, maybe 450lbs or something. I've put around 10k miles on them and haven't ripped any cv boots yet! It's a stiff ride but I'm young and dumb so I enjoy it haha.
Very nice. Not many ix's using gc's - I love the way it sits.

Im curious, if I used something like a 225/45 on my front 8", what tire size should I be using in the rear 9", to maintain the mandatory rolling diameter without stretching out the rear? Im not absolutely set on this sizing yet, dont get me wrong, this is for my "showey" wheel application. Ive already got my winter setup, track wheels, and even a set of travel wheels already sitting and waiting.. but I need to figure out this show season set. .. I want to know how to calculate the sizing when I finally reach an optimal size for the fronts to fit and match the rears as ill be installing based on my eye more or less. . Ill be doing bodywork to compensate any future rubbing so my only clearance concerns are with the factory shock/struts and spring perch in hopes a 5mm spacer at most will resolve any of that....
I know you're doing a magazine build... but do you have to use the staggered tire setup? Wider rear wheels don't make any sense on an AWD car. If anything, you should use M3 fenders and run wider wider wheels & tires in the front.
he could do it if the tire widths were the same on front and rear wheels.
fronts you want ET30-33, rears will be a lot tougher, there aren't a lot of high offset 9" wheels available. maybe switch to RWD trailing arms/hubs/brakes so you can run lower offset wheels out back?
they should fit but I'd put a 10mm spacer, ET42 is a bit high for such a large wheel. it'll look really sunken into the fenders and there may be strut contact issues.
I thought stock ix offset was was about 42? normal e30 bottlecaps were 35 and weaves were 30?
195 tires are 7.6 inches, so with a near stock offset and near stock size tire.... it should be perfect?
That same tire on a normal e30 bottlecap would put it (42-35mm) 7mm closer to your strut and would def hit?
You have offsets backwards. Bottlecaps are 7mm further from the wheel, not closer.
Actually they are even further than that because it also depends on the width of the rim. Bottlecaps and weaves clear by a country mile, they are 1" and 1/2" narrower that the stock ix wheels.
Generally with a wider wheel you want a lower offset than stock, but even stock wheels can take a 10mm spacer no problem.
