Ideal NB offsets for new 18's - paging Mr. Verburg, David in LA?
Hi Guys,
Now that Fikse is off the list, I am ready to bite the bullet on BBS motorsports E88's. Spoke to the folks at head office in Atlanta, but did not get 100% clarity on offsets actually available.
Anyways, assuming they can build 'em, are the stock widths and offsets the best option to go with (18 X 8 and 10) ET 52 and 65? I am not sure I will run tires bigger than 225/265, and my fenders are not rolled (yet). Maybe 235 fronts? 285 rears?
I guess my question is, would you stay with stock widths and offsets, or push things a bit... 8.5 fronts?
Are the stock offsets truly "ideal" or can they be inproved upon?
I want to do this right, the first time!
Thanks in advance
Matt

in my never ending search for better than perfect I've been investigating wider
I have used 9 ET50 front but was unhappy w/ tire choices. You have to consider the tires that you will use at both ends and their impact on wheel width.
My preferred front would be 245/35 x18 which wants an 8-9.5" wheel and preferred rear would be 285/30 which wants a 10-11" wheel. Keeping in mind the fact that the best performance will come from the widest design wheel that means that 9.5" front and 11" rear would be best.
Unfortunately after mapping out the wheel wells neither 9.5 nor 11 will comfortably fit. So back up a step and compromise 8 & 10 are both in the design spec if not best they still work pretty well, I think that w/ 10 ET67 the 285/30 would be a bit more comfortable fit and if I were to buy another set I would probably want 8.5ET56 and 10.5 ET70
For your use(no pro motorsports) the BBS RS-GT would be a good compomise too, 8.5 ET56 & 10 ET65

Thanks Bill. It really is about compromises... I guess it also depends on how much you are prepared to fidlle with ride height and camber.
I like the RS-GT's too, just prefer the E-88's. I like the fact the E-88's can be serviced if damaged.
Best,
Matt

well either way 8ET52 and 10ET65 are perfect w/ 225/40 & 265/35 x18. I also see the same wheels w/ 235/40 & 285/30 at the track, though I would need to fit a set to be sure that they would work on my car.

On the fronts, I think it's typically the insides that rub when you keep going wider (that's true for me) so I'd lean more toward ET50. But ET52 is probably fine since you could just add a thin spacer.
I would guess that in the rear you'd hit the fender first, so probably ET67 to ET69 might be better (but I'm speculating). Somebody here swears he runs 295 in the rear on a lowered car, so you could do a search then ask him.

I have used 235 and 285 on correct size RS speedlines, with sub lowered RS suspension settings without a problem..(obvioulsy rolled arch lips on the RS).

Hi Mark,
I know of a set of E88 9 & 11's, that fit my car (stretched and rolled fenders) with tires for 3k if you are interested..... I was going to buy them, but decided to stick with Fikse's.....

Glens's 996 Cup wheels? YOu had them on your car? What accomodations did you have to make for them?

Longer wheel studs
Fenders rolled tight
RS fender supports (and stretch the fenders slightly) on the rear
2.2 deg camber in rear
3.0 deg camber in front
You would struggle to get them to fit on a street car..

I have the same car... stretching and rolling is legal in class, (and truth be told, the stock fender supports can be bent to match the RS ones)... As far as the front, I got lucky and the RSR shocks that I am using have a little camber built into them, the front fit with plenty of room though, 2.5 would probably still work. The trick is working up the courage to break out the BFH and wail away....

For any one else that is interested
the 996Cups came w/ BBS E88 9ET46.5 & 11ET59
the rears will stick out 19mm more than a 10ET65, that's going to call for a lot of stretching of the fenders
