The use of a MAZDASPEED intake (0000-06-5150-KT) and a MAZDASPEED high-flow exhaust (0000-06-5450-KT) is required and pushes power from 170 to the 200 hp range. All MX-5 Cup vehicles are equipped with a six-speed manual transmission and may be run with the optionally available limited-slip rear differential.
The MAZDASPEED Motorsports Development MX-5 Cup suspension kit is sole approved suspension enhancement of 2006-spec race cars. The kit consists of coilover shocks with 5-way dampening adjustment, spec springs and stock height bumpstops as well as anti-roll bars.
The braking system has its own specs for rotor size but modifications can be made to backing plates and dust shields while pads, fluid and lines can be replaced, the latter can be upgraded to racing spec stainless steel or Teflon.
Wheels are limited to two 17 x 7 OE offerings, each weighing and costing the same. The series spec tire is Hankook’s DOT-approved 225/45-17 Ventus Z214, which sports a C50 compound. The wet spec tire is the Ventus R-S2 Z212.
