It is paired with a Getrag six-speed transmission and Z4 rear end with Wavetrac differential and 3.46 gears. The 1300 kg car rides on Ceika adjustable coilovers, H&R sway bars, Superpro front control arms, and PMC Motorsport rear control arms. Stopping is handled by Ceika six-piston calipers with 355 mm rotors in front and Ceika four-piston calipers with 330 mm rotors in back.
