No different at all from UP, MPP, Redwood, etc disclosing spring rates. These companies pay for R&D, Engineering, and manufacturing specific specs. Not just cookie cutter builds and volume. To add on top of offset Signature also calculates tire size, camber, and wheel under full compression. Do any other wheel companies do that for free for customers? Top companies 3D scan their carsThe signature wheels do look awesome, but the business model seems to be keeping offset a secret.
Stolen from the S group but they were able to figure out how to get 335 wide tires on the new Plaid from 295. That's 4 tire widths up from stock with a flush fitment. A porsche 911 turbo is a 305 wide tire and gt2rs is a 325....just FYI
