I'm looking at some 17x7 wheels with a ET of 48. Theses wheels will need adapters. I'm trying to figure out what thickness the adapters can be.

For example if I use a 32mm thick adapter I will have a total ET of only 16 and I don't think that will work without fender friction.

So how thin will the adapters need to be to avoid the dreaded fender friction.

BTW... I would like to run 205/40/17 front 215/40/17 rear with some lowering springs to get a nice stance.

Thanks,
Jeff

You are going to want to run the smallest adapter possible since you are not going to have much stretch with those tires. An 18mm is probably your best bet.

Depends on how much lower you plan to go?
I had slight rubbing in the rear with 17x7 ET38 wheels and 215/40 tires with H&R springs. Thus, 10mm spacers would probably be just about right for your 48mm offset wheels. The problem is that 10mm is not a standard size spacer due to the hub snub used to center the wheel.
