Hi I have a 2010 G37S Coupe RWD with everything stock and I'm planning on getting Eibach lowering springs with the H&R DRM Spacers.

I currently have another set of winter rims 225/50/18 all around (Sport Edition A7 Black Painted) that have 35mm offset and 5.91" back spacing.

I've searched the forums and found I shouldn't have an issue with my stock rims if I go 245/40/19 and 275/35/19 tires with 20mm front / 15mm rear spacers but I'm not sure if my winter rims will clear the fenders or any issues with the fitment after I do lower it with the spacers.

Thanks.

 

What width are the winter set? Should be fine as long as they currently clear your big Sport brakes.

 

My winter sets are 18" x 8"
Will my front wheels protrude out with the eibach springs and 20mm spacers?
I would like to go with F 20mm and R 15mm spacers with my stock 19's but I'm not sure with my winter set's 35mm offset and 20mm spacer. Any chance of rubbing..?

Thanks,

 

So your final specs will be 18x8 +15 with the 20mm spacer. I am running 9.5 +35 up front, and according to the tire/rim calculator, those two specs are almost exactly the same. With a drop and natural camber, you should be fine. I don't rub at all and it is nearly flush.

 

That's good news. I was concerned because I'm at stock height right now and without the spacer it already looks close to the fender. I guess the drop really tucks the wheels in!
