Default 993 NB wheel size question

Can anybody tell me if the following wheel would fit on a NB 993 without the need for spacers or rolled fenders? Car is only slightly lowered.

Front 8.5J x 18 H2 E41
Rear 10J x 18 H2 E47

Seems the offsets are not correct but seller says they came off a 1996 NB 993.

need spacers, and then the rear might not fit. rears are wide body fit for sure.

What's "slightly" lowered? Mine is at RS height. My rears are 9.5 ET 47 and is already tight. With 10 ET 47, they will stick out an additional 6mm. Possible with aggressive negative camber and rolled fenders.

see below for a useful offset calculator. you can put in the size you have & the size you want and it will tell you what the difference will be (both inside & outside).

Need spacers where? An ET41 8.5" front is at the limit and rears will fit with narrow tires.

I am running 18x8.5 ET41 up front with 225/40-18 Pzero Rosso with 2.3 degrees neg camber and pretty low. No fenders rolled and I dont rub at all driving straight or turning BUT as soon as a driveway incline is the case, I scrub the passenger side mildly. If I were 5mm higher OR the fenders were in probably less than 3mm, I'd be fine. Also, after installing thicker swaybars, I expect my minor rubbing up front to be reduced.

Also, in rear, I'm running 18x11, ET60 w/ a 285/30-18 Pzero Rosso with 2 degrees neg camber. That puts the outside of my wheel/tire exactly the same as a 10" ET47... and I dont rub in rear at all, inside or our on fender. So, if youre running not more than a 265/35-18, you should be fine.


****... I just realized this was a thread from 2012 and someone just bumped it to ask if 17's clear Big Red, LOL. Sorry... I'll keep my post for the sake of someone else searching new info.

^ You made me lol, Rich. Still, good info for those searching. On that note, my response above was on my old NB, not this WB.
