Default Anyone running 17x7 wheels? Trying to get correct offset.

I'd like to run a 17x7 with ET25 with 225/45R17 tires, and wondering if that'll work on a 1997 9000 Aero lowered with Abbott springs.

Anyone care to venture a guess before I fly them halfway around the world?

Thanks!
Ben

Do a search, number of people are running 17 wheels. The offset sounds right, but I am not sure.
I am running 17x7 but I custom ordered bolt pattern adapters, so, now I am running on the civic bolt pattern which allowed me to get cheap 17 wheels in the us. In my configuration I have half inch adapters and 17x7 wheels with 225/45 on them. ET 42. Also I have lowered b&g springs. With load in the back sometimes on bumps rear wheels rub on the side on the fender arch, so, in the future I'll probably go staggared having 215s in the back and 225 in the front.

Kim, thanks for the response. I see that you're local and have a Porsche as well ;-)

Given that you are running 17x7 with offset of ET42 + 0.5 inch adapter, that puts the effective offset at ET29.3.

So, with the same tyre size at 225/45, a ET25 will sit further out by 4.3mm. If I mounted 215/45, the outer wall will have 0.7mm more clearance than your setup, which isn't a lot. I think a 205/50 may be the way to go.

Thoughts?

i ordered my 17x7 (custom drilled, bored and machined) to fit a saab 9000, and they said the correct offset was 33, which is what they machined mine to
i'm running 225/45 and was running H&R spring in my aero, and found a tiny bit of rubbing on the wheel arch trim, which was easily fixed, as the aero's arch trim has a lip that protrudes into the wheel arch, but can be ground off with a dremel or similar

Seems there a bit of variance here between and the right ET is between 30-33 for a 225/45 tire size. I'll take a look and see if I can clear about 5mm of "meat" on the inside wheel arch.

Fundementally, I'm coming from stock super aero size of 205/50, so if my math is right (stock wheels are 6.5x16 ET27), I'm looking at an outward 12mm move with 225/45.
