The RSR Forged R905 is a monoblock forged wheel precision-engineered for two of the most celebrated sports car platforms of the modern era: the Toyota GR Supra A90 and the BMW Z4 G29. Machined from aerospace-grade 6061-T6 aluminum and finished in a sleek Anthracite Gray coating, the R905 delivers a split-spoke concave face design that enhances the aggressive, low-slung character of both the Supra and the Z4. At approximately 19.5 lbs per wheel — among the lightest in its class — and with a 1,600 lb load rating, it offers a meaningful reduction in unsprung mass for sharper turn-in and improved ride quality at any speed.

Q: Are RSR R905 wheels hub-centric for Toyota Supra A90 and BMW Z4 G29?
A: The R905 has a 66.5 mm hub bore. Both the Toyota Supra A90 and BMW Z4 G29 use a 72.56 mm hub bore, so hub-centric rings (66.5 mm to 72.56 mm) are included with your order to ensure a perfectly centered, vibration-free fit.
Q: Do I need different R905 wheels for Supra vs. BMW Z4?
A: Yes — the bolt patterns differ. The Toyota Supra A90 uses 5x114.3, while the BMW Z4 G29 uses 5x112. Both are available as standard R905 variants; simply specify your vehicle when ordering.
Q: Will the R905 fit the BMW Z4 M40i with M Sport brakes?
A: The 18" R905 generally clears factory M Sport calipers on the Z4. However, if you have aftermarket big-brake kits, confirm clearance with our fitment team before placing your order.
Q: What tire size is recommended for the Toyota Supra A90 with 18x9.5" R905?
A: 265/35/18 front and 265/35/18 rear (square setup) or 245/40/18 front / 275/35/18 rear (mild stagger) are the most popular tire configurations for the Supra A90 on 18x9.5" wheels.
Q: How long does it take to receive the wheels?
A: Forged wheels are built to order. Typical lead time is 4–8 weeks from order confirmation. Shipping to Europe and North America typically takes 7–21 additional business days.
