Nice classic look and Champion quality is one of the best forged wheel money can pay.
20" ?

 

Those are possibly the best looking wheels I've ever seen on a 997, so far. Kinda like a 5 spoke version of my gp7s. They have less curved lines than the rennworks wheel, and very different from the neez rim, imo. However, there is just so many ways to skin a cat, sooner or later you'll find two or more very similar wheels for these cars.

Honestly, the wheel may look like other wheels already out there but you can only change the way a 5 spoke looks so much...

Kudos to Champion Motorsports and I wish them continued success...
