Tried out some 20" wheels today.

- American Racing 18" pin drive wheels
- Custom Wilwood Big Brake Upgrade

Superformance 427 Cobra vs. Spyker C8

Trick question RodKnock, why did Superformance run with their 18's that day?

Meanwhile back at the ranch some self-respecting Cobra owners chiming in on the 18's.
Superformance NEW 18' American Racing Rims!
Nitto's: Front 275/40 ZR18, Rear 335/30 ZR18

Cool. You dug up a 3 year old thread started by Hillbank, an SPF dealer.

Why did SPF run 18's in the video? Oh, I don't know. I'm just spitballin' here, but maybe, since the younger crowd really like big shiny wheels and SPF desires to sell more Cobras and make more profit, SPF installed the bigger wheels to expand their product's demographics (i.e., install big shiny wheels = more sales to kids)?

Two math equations for you to think about:

1. More aluminum + more rubber = More Weight

2. Authentic-appearing Cobra Replica Does Not Equal Modern Sports Car.

Again, big shiny wheels are discussed at length over on the C7 Corvette Forum. You may find a discussion about owners going from 20's to 22's or more
