Iperformance has become distinguished as the world's top manufacturer and supplier of performance parts for Isuzu, Geo Storm, Asuna Sunfire, and Lotus Elan M100 cars, and we now bring that excellence to owners of all makes and models of cars, but we still offer nothing for trucks or suvs.


Welcome to the Iperformance website.

Over a decade ago, we set our goal to design and manufacture top quality, tuner grade parts for niche cars outside the mainstream, on the level of such greats as HKS, GReddy, Stillen, Millen, Nismo, and TRD. In the following years, we distinguished ourselves by creating and offering the finest power train, drive train, and suspension products available for non-mainstream vehicles through our Isuzuperformance product line. Our expertise has been sought by such noted companies as American Isuzu Motors, Inc., Saturn Corporation, Daimler/Chrysler, Mantapart, RK Sport, and many others. Our technical articles have been printed in the pages of Sport Compact Car and other industry publications.

All of this because we did and continue to do what we set out to do to begin with, manufacture top quality, tuner grade parts for niche cars.

Thank you,

Bill Luton, Owner.
