PART NUMBER: 61-3115
17x10 Race Wheel Project!
Goal for our fastest autocross and track customers is correct offset for race use with aggressive fender roll. Chosen offset will assume well over 2 degrees negative camber front and rear, and the more camber you use the less fender roll you need. Fiat 124 SCCA XSB Class Racer shown here has -3 front camber, -2.5 rear. Yes, this setup needs coilovers with serious spring rates to fit and be effective, and ideally our front offset bushings (item 61-2201). We are using NO spacer in the front, and 3mm spacer in the rear, our site item 61-1786 (use less rear camber than the -2.5 in rear of our Fiat 124 and that rear spacer might not be needed).
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.
- Clears factory non-Brembo brakes
Our FRONT Wilwood Caliper-only conversions that retain factory front rotor require 3mm spacer
- Clears our REAR Wilwood Caliper-only conversion that retains factory rear rotor (as used on our own Fiat 124 shown here) - Clears our 12.88" Big Front Brakes (as used on our own Fiat 124 shown here)
- Does NOT clear factory Brembo front brakes. However, if you add our 12.75 inch "BIG BRAKE Conversion for Brembo" kit, then the Brembo caliper will be spaced further away from the center of the wheel to clear that lager rotor... and THEN this 17x10 wheel will clear that Brembo caliper.
- AP Racing 340mm Big Front Brake kit requires 3mm spacer
BRIAN APPLICATION NOTES: This combo immediately proved FAST with a 200 treadwear 245/40/17 tire in SCCA XS-B. Having proved the speed of this setup we approached our friends at Konig about doing this special production 17x10 so customers could have a 4x100 17x10.Please do NOT buy these for your street car, these are a RACE FITMENT for customers actually RACING who can understand the fitment details above and actually make use of the grip. Tight lug pocket means we suggest our various tuner lug upgrades with these wheels, such as our McGard Spline Drive Lugs.
Why not just 17x9 for 245/40 Tire? That's a 10 inch wide tire in some fast choices like Yokohama AO52 and maximized support of the sidewall results in much sharper turn-in response, more stable contact patch, more ultimate grip. On our typical courses same 245/40 tire on 17x10 consistently more than a second advantage for same driver in same car over 245/40 on 17x9, and that advantage is closer to 2 full seconds per lap at tracks like Chuckwalla Valley Raceway and Streets of Willow Springs!
Note that not all tires with label 245/40/17 size are really the same size, RE71R is the most easy to fit, Rivals take a little more work, and the new Yokohama A052 is way over the listed size and takes significantly more work (flat roll/pull in addition to really good camber like more than -3 front, more than -2.5 rear). If you want to run the Yokohama but fear you are not up to the job and getting sufficient flat roll/pull, we suggest you run one of these other tire choices listed above and know even that will take fender lip roll.
