Thank you. You have rated this product.

The Hypergram is a lightweight, 12-spoke design that is motorsport inspired in its construction, appearance and its ability to clear many big brake cars and upgrades! Perfect choice for SCCA STS Competitors! Utilizing Flow Forming Technology allows the Hypergram to be lighter and stronger. With an unusual range of aggressive sizing the Hypergram is finished in either Matte Grey or Race Bronze.

Wheels Specs:
*15x7.5
*4X100
*35mm offset
*73.1mm bore
*11.8 pounds ULTRA LIGHT!

Brian's APPLICATION NOTES: Likely the best bargain right now in flow formed wheels in this size, and very nicely finished. ONE CAUTION, it seems Konig is trying to play more like Enkei and included cast aluminum fancy center caps instead of industry standard cheap snap-on plastic caps. The result looks high end compared to plastic caps on wheels of similar cost but BE CAREFUL to do little more than finger tight with the very tiny allen head screws that attach the caps, use a dab of locktite, do NOT apply significant torque to the screws or they will strip out immediately!

REVIEWS

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
