HeLp...staggered wheels for G35X will it affect my VDC?

PLEASE HELP if you can....

I have an 07 G35X sedan and wanna buy my homies 20" momos.

My stock wheels are 17x7.5 +45mm offset and tires are 225/55R17. His Momos are F 245/35R20 +40 and R 285/30/R20 +38. According to some websites i checked his rims should fit right on. The only question I have is that I've read on one or two websites/forums that his wheels MAY throw off my VDC (vehicle dynamics control) because my car is an AWD. the overall diameter difference is only 0.04% but it is staggered just a little.

can anyone help answer if this is true or not? some websites say "yes" and some say "no"

PLEASE HELP...thnx in advance

I would not do it, because in your rims' case you would be running different rolling diameter tires front/back. thread covers the subject pretty well. Someone posted this in the thread, and I agree with it:
"if the difference between front and rear rolling diameter is less than 5% then the awd system is inactive. once it passes this threshold by way of the abs sensors, the awd ecu starts to transfer power to the front wheels. staggered wheels with tires that result in a different rolling diameter will result in the percentage changing, either it will be greater than 5% and the car will always send some power to the front wheels, thereby greatly reducing the center diff clutch life and increasing the diff oil temps, or it will take more than an actual 5% difference in wheel speed to activate, meaning that the handling and saftey characteristics will change, possible transferring too little power to the front wheels under certain circumstances. either way, a different rolling diameter (staggered wheel width) is probably not a good thing on these cars."

yea i forgot to mention that the Front are 20x8.5 and Rear are 20x10.

so based on what the info you provided the fact that the wheels are different WIDTH not diameter would throw off the AWD?

what do they mean by "rolling diameter"? my stock rims are both the same size with same offset so i thought if i bought rims that the overall diameter was within 1% i would be ok even though the width are not. is this not correct?

thnx

Width should not make a difference - diameter does. If the rolling diameter difference between front/rear (tires mounted) is less than 5% IMHO it would be OK, but let others chime in. Basically, you want to get both fronts/rears to be as close in rolling diameter as possible. Knowing this, personally I still would not be comfortable running a staggered set on the X - however small, the possibility of messing with AWD or dealer refusing a warranty repair because I ran staggered doesn't make it worth it to me.

^^ but if your tanny ever hiccups, I would definitely swap back to stock wheels before you let a dealer see it.

I'm running the same setup on my X but my rears are +37. How did yours fit? I had to dial in a decent amount of negative camber to clear 285's on a 20x10 +37...

aToxic... I'm liking the larger tire setup. Nothing wrong with some extra ground clearance on an X. I wanted to go a bit larger with mine but was worried about clearance issues. Either way it looks good man
