ISR Performance

ISR Performance is a sport-car parts brand, and this is a small range aimed mostly at Japanese sport cars rather than trucks. The main groups are suspension, with Pro Series coilovers, control arms and toe arms, and exhaust, with axle-back and straight-pipe systems for the G35. There are also a few clutch, water pump, towing and forced-induction parts.

The vehicle list is short: Infiniti G35, Mazda Miata, Subaru BRZ, Lexus GS300, Toyota Corolla and Nissan Sentra. Titles also use chassis codes, such as S13 and S14 for the 240sx, Z32, Z33 and FC3S, so match your chassis code to the title.

Pick by chassis first. Pro Series coilovers are listed per platform, so there is one listing for each of the cars named in the title. Control arms and toe arms are rear-suspension parts, each listed for its own chassis, and the exhaust options differ in layout: MBSE is an axle-back, EP is straight pipes with dual tips. A universal racing tow strap in red is listed too; it is not tied to a vehicle.

Browse shocks and struts or exhaust systems to compare across brands. Each product page lists the years, makes and models it fits. Ships across Canada, priced in Canadian dollars.
