After doing some careful measurements, and using the proper forgings and barrels, I've figured out how to make 17s fit the front and rear of all Gen 3 and Gen 4 Vipers. I just received my first pair of rear wheels to try out, and they fit perfectly. All you'll have to do is install the typical parking-brake line swap kit, which is also needed for 18s and some 19s. No grinding, no clearancing. It even retains the factory parking brake.

This wheel is a 17x10.5, which I had built to run Hoosier 28x10.0x17 drag slicks. I also used the same wheel to test fit the front, no issues. I believe we can go wider on the rear, if people want to use them for road racing and such. I've personally never seen a 3-piece 17" wheel on any Gen 3/4 Vipers with factory brakes.

This isn't a cheap modification, but nothing looks better or fits like this. Example pricing, for drag or road racing combos.

Drag: 17x4.5 front, 17x10.5 rear, standard finishes w/ polished lip = $3965/set
Roadcourse/auto-x: 17x11.0 front, 17x13.0 rear, standard finishes w/ polished lip = $4350/set
3-week rush build program available.
Can be sold with tires mounted/balanced

I have 3 pairs of rears for my car. 17s, 18s, and 19s. LOL
