^Yeah, that's who I was planning on purchasing them from. I got some nice 18's on Falken GRB FK451's from EdgeRacing for $950 SHIPPED!!! for my IS.

 

I don't think my question was fully understood. I have the opportunity to possibly buy snows for my 2006 6MT Sedan whose stock size is 235/45/18.
The snows come off a G35 coupe with sizes 225/45/18 (2) front and 245/45/18 (2) rear. Will these affect the VDC??

I think you are fine. I run 225-40 / 245-40 19s on my sedan and it's fine.

But if you want to know for SURE. Run your tire numbers in tme Miata net tire calculator and see if it's within 3%.

Report back.

 

VDC will be fine.
