I'm about to pick up used set of RPF1 for my FD. I was wondering if this setup would sit flush. Or work?

Front: 17x8+45 235/30/17
Rear: 17x9+45 255/30/17

 

No this would not sit flush. If you want a nice flush I suggest you go into the 20-25 offset

 

danng you know what size spacers i would have to run then?

 

Run a 25mm.

 

i'm on F: 17x9 +22 and R: 17x10+18 with 255's all around. regular race alignment and it sits flush, but not Herra Frush. I like to drive my FD too. EDIT: oh yeah, rolled fenders of course.

 

As other have said no. And I'm no where near flush and I run:
18x8.5 +42
18x9.5 +40

Performance wise it's great... But from time to time I think about adding some spacers.







Make sure you get your fenders rolled before installing the spacers tho.

 

I would say look for a different set, 8" wide fronts are not much of an upgrade.
