PART NUMBER: 61-2662
17x10 Race Wheel Project!
Goal for our fastest autocross and track customers is correct offset for plug and play with just a 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. Our Budget NC Racer shown here has -3 front camber, -2.5 rear. Assuming over -3 camber front need mild fender roll for 245/40 and medium fender roll for 255/40 RE71R on NC Miata, ton of roll and pull for 275/35/17 on NC (275/40 with light lip roll for RX8). Yes, this setup needs coilovers with serious spring rates to fit and be effective, lowered car to typically 13.25 height front, 13.4-13.5 rear measured from center of wheel straight up to fender lip, and ideally our front offset bushings (item 61-1054). Suggested MINIMUM suspension to control this big setup is at at least our MeisterR ClubRace with 10kg front, 6kg rear, or our FEAL 441 Road Race with 12kg front and 7kg rear.
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BRIAN APPLICATION NOTES: We have been racing our latest Budget NC Project on 17x10 that were originally made for Honda S2000 Racers and thought: why should the Honda guys have all the grip?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 relatively easy fit of 255/40 with 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.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 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!
Note that not all tires with label 255/40/17 size are really the same size, RE71R is the most easy to fit, Rivals take a little more work, and the new Falken and particularly the Yokohama A052 takes a lot more work (full flat roll with pull and better than -3 camber front, better than -2.5 rear). This is a RACE FITMENT, be prepared to do what you need to do to fender lips to make it work, and you might get bit of rub inside at rear shock towers that can be answered with less rear camber and/or some hammering on contact point. If you want to run the Yokohama or Falken but fear you are not up to the job of flat roll and pull, we suggest you run the 245/40 size (which still needs a roll, but less work for sure).
Fun new pictures of Bronze Hypergram 17x10 Courtesy Customer Simone Eid
First thing, first the bronze color on these wheels is very handsome (especially on my Crystal Pearl White club). I've also had the pleasure of seeing a black set in person and can definitely say that I'm glad I went with bronze.
This was primary an experiment for me in heeding the notes that Goodwin clearly stipulates in his listing of this being a race fitment. My particular application was to experiment reigning in the new found power of my 2.5L 1 Goal turbo setup. That car makes tons of torque and revs super fast, so the former 245 Michelin PS4S on 17x9 6ULRs were just not hanging on despite their best efforts. This was an extra set of wheels, so if it didn't work out, I'm not past a point of no return or anything, just swap on the previous.
Back to the wheels, so the fitment is TIGHT running the 255 "easy fit" bridgestones.. I was previously running. 12.5" ride height front/rear (somewhat tucked under the fender) and a direct swap on was just constant rubbing on any road with any kind of minor imperfection.
#1 - Got to raise the car enough for them, but enough to still maintain some decent static camber. I got coilovers, no problem, so I just raised up to 13"/13.25" front/rear.
#2 - You have to roll both the front and the rear fenders. With my camber and 245s on a friendlier 17x9 at 48mm, I didn't really have trouble, but on the bigger setup, instant shaving on the outer edge of the tire. I rolled the fronts immediately and trimmed the upper edge of the front fenders.
For the street, I'm running approximately -2.5°/-2.7° and 13"/13.25" front/rear. I'm happy for my goals.
The tracking is a little tight, so you're not doing super tight maneuvers in a parking lot without some rubbing on the inner front fender when the wheel is turned out.
It sounds like my trimmed fenders are now tapping my tires at speed. It's probably pressure from the air entering the front pushing them down a tad.
Bottom line is don't order these and expect not to modify bend/cut some stuff. The car will get significantly more noisy.
With these beefy bad boys, I suddenly seem to attract the attention of every muscle and boy street racer. Funny enough is that I think the tire/wheel size barely being contained also intimidates.
Grip is super phenomenal with 200 TW tires. Once warmed up, the tires just grip in the rear. It's probably compound more than overall width, but again this was an experiment.
I've got 17x9 hypergrams in transit to see how much friendlier it is noise wise.
Would I buy these again?
With the above compromises? Yes
Why? They're beautiful, you can always add fenders and mild spacers for inner clearance, and play with some big brake (caliper) kits on a 17 rather than an 18. Definitely know these are 100% race car in their design and application.
Thank you Brian Goodwin and team for bringing them to market. I don't know that I'll buy another 17x10 again, unless you decide to go and make a carbon/machine lip version. I hope you don't though!
