Offset requirements for fitting a 215/45 R17 tire upfront

[CB72]

After fitting a 205/45 R17 with no rubbing issue on my NSX, I wondered if a 215/45 R17 would also fit?
This would allow the use of Michelin's Pilot Sport Cup 2's, a must to keep up with the Porsches on track!
In my current configuration the answer is NO.
In fact the back of the outer side of the tire is very close to the chassis frame when the steering is turned.
The problem is mainly due to the 33 mm offset I use with my Porsche calipers.
I noticed that the Rays 57Transcend wheels accept large calipers with an offset of 43 mm according to SoS:

Pulling the wheel inside the arch will give more clearance at the rear of the wheel so that the larger tire should fit?
It would be great, if someone ( maybe [MENTION=4260]ScienceofSpeed[/MENTION] ) would test this combination.

I’m also curious about this tire set up. Has anyone tried this before? Pics?

I take it no one, given the replies, heh. I need new tires and am running Z1s on Volk CE28s, but wanted to look into getting in on the Pilot Sport action, but I can't find anyone anywhere that's posted if/how this could work. =(

I've seen that on the video that compares the old versus new NSX that the old NSX runs 215/45*17 tires.

It's at 10:33.
BTW the comments on the new NSX are harsh...

Oo nice, that's both a great vid and good to know. Thanks CB72. Also makes me feel good about having bought a gen1 and not trying to aim for a gen2 lol

typically most running 17" fronts are using 215/40x17... might be why there no responses.....

tho 33mm offset is at the low end of the range.....

I seem to recall that Dave (@turbo2go) ran a similar diameter tire setup but with 18/19 wheels and 225/40-18 and 275/35-19 Michelin Pilot Super Sport tires.

Well thanks we now have the answer:
18x8 30 and 19x11 45. 225/40/18 and 275/35/19.
He had to remove the liners to avoid rubbing.
