Advanti Racing's new RRF line of wheels are finally here!

RRF, or Rim Rotary Formed, is a flow formed process that results in a product that is stronger/lighter than lesser casting methods. The result is a STRONG 500 KG load rating in a 15x9 MX5 wheel that weighs only 5.5kg! NOTHING ELSE COMES CLOSE! Most everything else in this price range is gravity cast, pressure cast, or low pressure cast with heat treatment.

  • 15x9 4x100

  • Fits 225/45, 225/50, 245/40, 245/50, 275/35 tyres.

Always check clearance during install and after car is lowered to the ground, failure to do so can result in damage, death, tyres cut on guard lips, and other bad stuff! Takes optional 73/54mm hubcentric rings also available - Contact Us.

Tyre Size breakdown:
-195/50 and 205/50: not recommended
-225/45: Tyres fit NB guards with no mods needed given 1.5 or better negative camber, fits NA with slightly rolled guards and that negative camber
- 225/50: require rolling and pulling guards, removing liners on NA, NB only requires slight roll.
-235/50 Toyo R888: requires rolling and pulling on NA, roll only on NB, will rub top of tyre at full compression.
-275/35 require rolling and pulling, removing liners on NA, flat roll on NB. 20-30mm spacer recommended to fill aftermarket flares.

Will NOT clear stock suspension, need coilovers with 2.5 inch diameter springs or narrower and expect may still rub at full lock (which is not a real issue since full lock is only possible at parking lot speeds), 3mm spacers can be added if you are running so much camber that you rub inside control arms, etc.

Brian's Application Notes: WOW, what a bargain, never dreamed we would get flow formed strength in this price range. The benefit is wheels that are BOTH stronger AND lighter! You can buy lots of regular cast wheels for this same price and more that are not near as strong. Note that all other things equal, higher spoke count is stronger than lower spoke count, part of the reason this wheel is 10 spokes! Result is stronger and more dense final product with less weight than lesser casting methods!

Note we STRONGLY recommend our numerous upgraded lug choices with any of our new wheels, stock lugs are too short and fat to fit properly. Unlike the short and fat stock lugs that will result in scratching new wheels, all our replacement lugs have the socket tool bottom on the lug rather than the wheel surface, and are longer for more engagement with stud surface so they also stay tighter.
