Source for 16" wheels RSR body?

[skinnerd]

Checking to see what is available for 16x9 and 16x11?
To go on a 73 RSR replica.

Know you can still purchase 16x9 forged Fuchs with ET15 new.
Will these fit up front on a 73 w/ turbo/RSR flares?
Need to come up with a rear wheel....possibly get Weidman to fab up something special.

Trying to put together a tire/wheel package with a much lower overall diameter than what you usually see with 17" rims of 25.5-26.5" overall diameter.

Hoosier makes some road racing slicks that the GT2 classes use in the following sizes:
23.5x11x16 on the front
23.5x12x16 on the rear
Overall diameter on these are a much lower 23.5".
Should help overall acceleration on the auto-x course.
Unsure if these would fit under the turbo/RSR flares?

Also considering going the 15x9 and 15x11 route with an Avon slick, but the overall diameter is back up in the +25" realm.

Any thoughts on the above?
Or other wheel choices that would be suitable for auto-x and track events?
Kodiac, etc?
Thanks
