This Enkei 17x9 RP-F1 is our TOP wheel choice for MX5 Miata track and autocross! Includes Enkei Aluminum Valve Stems!
Nothing else comes close to this combination of ultra light weight and strength (Rolling Rim technology used to make these rims results in grain alignment just like in forged wheels for greater strength than is available from mere cast wheels but at much lower cost than forged wheels).
Takes a 73/67 ring for those that want the hubcentric rings, available elsewhere on the website.
Narrow extended length lugs are recommended (see McGard Spline Drive lugs here on our website).
See more pictures of these 17x9 on our MazdaSport Magazine project car...on THIS WEBSITE in our forum wheel gallery. Note that center caps not included on this Enkei but available on the website for those that want them.
BRIAN'S APPLICATION NOTES:
This is our top choice for track days with TOYO R888 tires for the NC Generation Miata. Also works great as MX5 CSP or STR class autocross setup. Requires a mild fender lip roll to fit 235/40/17 or 245/40/17. Worth the effort for an amazing amount of grip for a very LOW weight and high strength...see pictures in wheel gallery section of our forum. This 17x9 is a popular choice for both Mazda MX5 and Honda S2000.
The Enkei Most Advanced Technology (M.A.T) process combines one-piece cast wheel technology with a rim forming spinning process. Using this rim forming M.A.T process improves material strength dramatically as compared with normal cast wheels. Rim-Rolled technology shapes the rim to improve material elongation without sacrificing the wheels hardness.
All Enkei wheels are engineered to pass rigorous testing. In fact, Enkei established its own test standard called "Spec-E," which is tougher than JWL requirements. Enkei s Spec-E test setting requires a higher drop point in the impact test and 20% more cycles for the rotary bending fatigue and dynamic radial fatigue tests than JWL standards.The Spec-E represents Enkei s confidence in its technology and quality of Enkei wheels.
