The BBS RI-A is a one-piece forged wheel built on the company's motorsport program, the same RI-A design campaigned in Japan's Super GT series. It pairs BBS's multi-stage die-forging process with a split five-spoke face, giving it the strength-to-weight ratio of a true forged competition wheel with a finish quality that holds up to daily and track use.
Forged from 6000-series aluminum under up to 18 million pounds of pressure, the RI-A delivers low unsprung weight, high rigidity, and the long-term durability BBS forged wheels are known for. The result is a wheel that improves handling response and steering feel while standing up to hard track sessions.
This set comes in BBS Signature Diamond Silver, a bright metallic silver that brings out the depth of the concave split-spoke face. Center caps (Black/Gold or Red/Gold) and the BBS PFS fitment kit are included.

Fitment
Sold as a square set of four (all four 18x10.5 +22 5x120). This is an aggressive fitment for:
- BMW E9x M3 (E90 / E92 / E93)
- BMW E46 M3 (aggressive)
Square 18x10.5 +22 is a wide, low-offset setup. The front fitment is aggressive and typically requires camber adjustment and fender work. This is not an OEM-style bolt-on. Confirm clearance against your brakes, suspension, and fender setup before ordering. The included PFS kit must be matched to your specific chassis, so provide your year/make/model when ordering.
Fitment Disclaimer
Fitment listings are a general guide. Wheel fitment depends on your vehicle's year, trim, suspension, brake setup, and tire choice. It is the buyer's responsibility to confirm correct fitment before purchase. AutoTecknic is not responsible for incorrectly ordered specifications.
Returns
Mounted wheels cannot be returned. Wheels that have had tires mounted, been installed, or show any signs of use are non-returnable. Inspect your wheels thoroughly before mounting.
