This is the Enkei TSP-5. It’s a fork off the RPF1, with the same successful design elements centered around stiffness, and lightweight construction… except a bit more chiseled. They’re made using Enkei’s MAT Technology, which is a sweet-spot hybrid between casting & forging. The wheels are spun at high speed during the early production process, causing the metal to ‘flow’ to the outer perimeters. The result is a stronger, lighter wheel without the expense of a full-out forging process, and without the porosity that can result from casting. These are currently available across 17 & 18” diameters, and currently available in silver, matte black, or gold.

MAT Technology Explained

The Most Advanced Technology (M.A.T) combines one-piece cast wheel technology with a rim forming technology called spinning process. Using this new technology of casting and rim forming by M.A.T process, is critical to improve drastically the material property and strength of the wheels.

Earlier this year I got set of these for my Mazdaspeed 3 (along with some Continental ExtremeContact DWS tires that I just can’t praise enough), and I’m really glad that I decided on these. I love the look, and the performance improvements resulting from a lighter set of wheels is always awesome.

I get asked all the time about them, people curious what type of wheels they are, and so I gather that maybe not many people know about these bad boys. I highly recommend the Enkei TSP-5 if you’re in the market for performance wheels.
