Steve installed wheels onto my Atom3 and they clear the Alcon calipers easily. The offset on these wheels are super aggressive. They will result in tires that sit proud of the fenders - like in my Atom2. Compared to stock, the rear track is widened more than the front as a ratio . The rear wheel is also now 8" wide vs 7"(stock). The front wheel is slightly narrower at 6.5" vs 7" stock. I believe this may be the perfect tweak to dial out some oversteer for drivers like myself.
We will install wider tires (most likely Hoosiers) and run at Laguna Seca in two weeks. I will report back after completing our test.
