Thoughts on this HPDE track tire/rim setup?
Stock 2015 C7 Z51 w/ Mag Ride
(will not be lowered - stock ride height)
TSW Interlagos 19x9 (front) +50 offset [1650 load rating]
Nitto NT01 235/35/19 (25.47" overall diameter)
TSW Interlagos 19x10.5 (rear) +65 offset [1650 load rating]
Nitto NT01 305/30/19 (26.26" overall diameter)
How would they sit? I don't want them rubbing or sticking out and looking stupid. Would like them to set as close to OEM looking setup.
Stock OEM difference front to rear is .7 and this is .79 as I'd like to be able to use all aspects of the traction control and stability system if so desired.

I love NT01's for the track, but I would be concerned about what everyone has mentioned. You may be pushed out too far with not enough offset and you are shrinking your front footprint while enlarging your rear. You would be better off maybe trying 275/35-18 up front if you haven't bought the wheels yet.

I have a set of TSW. The OEM 285 rear is barely passable as it is. 305 would look ridiculous and would surely rub if the suspension compresses enough. I have a SC and need wider tires badly for traction. If I thought the TSW offset could handle 305, I wouldn't have consider getting custom forged.

Here's a wheel offset pattern:
285 rear tire at 65mm offset
295 rear tire at 70mm offset
305 rear tire at 75mm offset
315 rear tire at 79mm offset
As for tires, the R888 is really the same compound as the NT01 but has more sizes.
The R-S3 is available in 305/30-19 and is a great tire.
The AD08 R is available in 305/30-19 but is extra wide and extra stiff. Better run this 305 at 79mm rear wheel offset

I have the Interlargos wheels and they look great on the car. I am exactly in the same boat, I ran slicks last year but I am going to move to a DOT tire I can drive to and from the track.
I am going 275/35/18 front 305/30/19 rear. A 295 is too small for that wheel. I ran these sizes in slick 275/295 and they had zero issues rubbing.
I can't decide between RS-3's, NT-01's or R888's.
I have had NT-01's on my M3 and the shoulders always seemed to wear down quickly. The RS-3 is a good tire that is what I run on the street for my M3 now, it isn't nearly as good as a slick but it is a good DE tire.
The problem I have is I am not sure they are any better than the Stock PSS. Those are pretty darn good. I bought track wheels though so I wouldn't ruin my stock wheels and could get smaller sizes.

Of course, the hard part will be finding affordable, lightweight wheels in the right width and offset...
