The new 20” Signature Wheel SV306S setup is finally mounted on the GT350R. This is the first set to be mounted on any car, my first set of 20” wheels, and I wanted to get your thoughts. Here is the pertinent visual setup on the car and my takeaways. Photos taken by Austin (Summit SS on Instagram)

20x11 / 20x11.5 with modified GT350R offsets
Brushed Bronze Tinted Centers

Carbon Composites by MAD 11-Piece Carbon Fiber Exterior Kit

Street tire sizes to fit a 11/11.5 wheel in a 19”-20” wheel are limited. SC2 and other track tires don’t work for me driving in the cold, wet, or having poor tread wear. The 305/325 combination gives me streetability, endurance, and the ride quality is surprisingly good on the Magneride shocks even with the small sidewall. Not feeling beat up at all, but mileage has been limited. Wheels came out great, and the offsets I developed worked very well for concavity. Probably wont lower the car as I have a separate set of wheels coming for track use. Overall very happy with the outcome, and amazed these 20” wheels in wider offsets still weigh less than the OEM 19” GT350 (33lb) wheel. I can custom build these for any car, as well as our many monoblock options.

Questions about pricing are better sent via DM/PM/Email/Messenger as this is not a for sale advertisement, just sharing photos of my car with the community. Tag a bro, click a like, hit a follow. Enjoy the photos and hope to see you in Signature Nation soon.

Now that is badass looking. Shocking that those wheels are lighter than the stock ones.
Pretty amazing what can be done with a fully forged wheel. Surprised me as well.
