I would like to hear people's opinion on these- Should I run 255/40/17 on 17x9's or 9.5's? I have camber plates...but it seems like more of an expense with the 9.5's due to the spacer need. Thoughts?

If I were to run 245x40x17 on the front with the 17x9, I shouldn't have to change the stock camber settings, correct?

MORE RUBBER!!!! The added expense is minor and you've gone this far.

The 9.5's will provide better sidewall support. That is very important for a heavy car. The optimal wheel width for a 255 tire is actually 9.5". You can even see in the photos that the tires are ballooning on the 9" wheels, and this will result in added sidewall flex. Everything is a compromise though, as the 9.5's are harder to fit up front, so they'll be out of reach for the majority of members. They need camber plates and a thin spacer (5mm spacers are cheap).

I would base your decision on the following:

If you have camber plates, and your coilovers are setup to properly clear the tires, then pick up the 9.5" wheels. The slightly higher cost will translate into very noticeable performance.

If you do not have camber plates, then run the 9" ET30's. That can be run with 255 street tires as well, it will just need an adjustment to your alignment depending on the tires used. If you install a 245/40/17 tire you don't need to do anything to the car. Just bolt them on and go. 245's square would work on both pre/post LCI models.

the 9.5 also do have more concavity correct?

They have the same amount of concavity. When you adjust for the width/offset change. The two wheels are within 1mm of have the face of the wheel at the same place in orientation to the mounting point. All the concave 17's share the same amount of concavity.

good to know, i think i was thinking about the 18s (or am i wrong again) lol.

anyways, patiently waiting for these wheels

+1 for apex wheels. I ran their 1er-offset only Apex Aero-7's and loved them.

The Arc-8s are even better IMO!

[e90pilot]

Will a fixed camber plate provide enough clearance with a 9.5? I'm able to get 2.3 of negative camber up front.

post some more pictures from the side of that gray e92 from the OP?

Great post- very informative. Exactly what I was looking for. I have vorshlag plates- I will go with the the 9.5's / 255 all square. Thanks!!

Any idea on when these will be priced/available?

Is there any downside to running these staggered?

What's the largest tire width I can fit on the rear? Do you think 265 or 275 would work with 17x9.5?

The reason I ask is because I want to use these for both the track and the drag strip.

Thank you!

Your situation is unique because of the drag application. There is no down side to running a staggered setup, besides the natural tendency for the setup to understeer in comparison to a square setup. You could definitely install a 275 or 275 drag radial on the 9.5" wheels.

Shiv from Vishnu Performance will be doing the exact same thing on his car when our 9.5" wheels arrive (He's currently running an 18" ARC-8 setup for the street).

Awesome. Thanks for the reply. I'll definitely join the group buy once these wheels arrive!

But the question is why would you want to run that much rubber up front if you're not going to change camber settings? All that rubber up front w/o any negative camber dialed in will lead to worse turn-in.
