Need advice on swapping current setup from a G37S Coupe to the RC F Sport

20x9 +32/20x10.5 +45 Vossen CV5

Front W/ 245/35/20

Rear with 285/30/20

Can I cleanly swap these two cars wheels without problems?

I also want to lower the car pronto, but haven't seen any avail springs yet. I know some people have lowered them on the Tanabe GS springs? I also saw that they had an AWD model for the RC.

What is the exact model number I would need and is it safe at this point to lower it?

Thanks for all the help in advance!

 

What I've seen done with the RC is the following.

20x9 ET38 w/ 235/35/20
20x10.5 or 20X10 ET45 w/ 275/30/20

I think with your tire sizes you may experience some rubbing on harsh bumps or dips in the road.
