PART NUMBER: 61-2661
17x10 Race Wheel Project!
Goal for our fastest autocross and track customers is correct offset for plug and play with just mild fender roll. Chosen offset will assume over 2 degrees negative camber front and rear (our Budget NC Racer has -3 front, -2.5 rear) and mild fender roll for 245/40 and medium fender roll for 255/40 on NC Miata, 275/35/17 on NC with good fender lip roll and pull, 275/40 with light lip roll for RX8.
The Hypergram is a lightweight, 12-spoke design that is motorsport inspired in its construction, appearance and its ability to clear many big brakes! Utilizing Flow Forming Technology allows the Hypergram to be lighter and stronger.

Always test wheel for adequate clearance to fenders, chassis and suspension components before using these wheels. Failure to do so could result in vehicle damage, loss of control, injury or death.

BRIAN APPLICATION NOTES: We have been racing our latest Budget NC Project on 17x10 that were originally made for Honda S2000 Racers and thought: why should the Honda guys have all the grip? To get that Honda fitment on our NC Miata we had to install long ARP upgraded wheel studs (not an easy install on NC) and 9mm of spacers to make an effective 43mm offset, which turned out to be right offset for easy fit of 255/40 with medium fender roll on an NC Miata. This combo got us numerous Top Time of Day finishes, see video below. Having proved the speed of this setup we approached our friends at Konig about doing this special production 17x10 so customers could have an easy fit 17x10 without having to do the arduous install of long wheel studs and spacers. From prior racing efforts we know NC customers can use this for Hoosier 275/35R17 with fender lip roll/pull, and RX8 customers can use this wheel for 275/40/17 and just a mild fender lip roll.
Why not just 17x9 for 255/40 Tire? That's a 10 inch wide tire and maximized support of the sidewall results in much sharper turn-in response, more stable contact patch, more ultimate grip. On our typical west lot courses same 255/40 tire on 17x10 consistently more than a second advantage for same driver in same car over 255/40 on 17x9, and that advantage is closer to 2 full seconds per lap at tracks like Chuckwalla Valley Raceway and Streets of Willow Springs!
