Building and Tuning Coilover's for Classic Japanese Cars is something that we have offered for the past 20 years! Over that time, we've tested lots of Shock and Spring options to find what works best for each specific chassis! Our Street Spec builds will turn an Economy Car into a proper handling Sports Car and we have experience with Drifting, Rally, Drag or Road Racing Coilover builds!  

Our custom Coilovers can either be built with your cars original Strut Casings or with our fully fabricated Evolved Strut Casings. Koni Sport Adjustable Short Stroke Shocks are used with HyperCo Hyper Coils as our standard springs or you can choose to upgrade to springs from Swift Japan. We have suggested Spring Rates based on how your car will get used but you can also choose any Rate that will fit your specific needs. Camber Plates are a suggested upgrade for an easy install and we will include the necessary Camber Plate Upper Hat System with this choice! 

Please review the available options on the right side of this page

OEM Strut Casings:

Our Front Coilover Conversion using your cores includes inspection, sand blasting, shortening the OE strut casings and then powder coating. We rebuild them using brand new Gland Nuts, the Koni Sport Short Stroke Shock Inserts, T3 Coilover Components and your Spring choice! Due to short supply of strut casing cores, you must be able to provide cores to complete this Coilover Conversion. If you are not able to provide strut casings then please choose the Evolved Strut Casing option. 

T3 Evolved Strut Casings:

The Evolved Coilover Conversion includes fully fabricated OEM style strut casings with spindles that are fully machined from chromoly steel for extra strength and rigidity. Each unit is powdercoated in a brilliant gunmetal grey and then built using brand new Gland Nuts, the Koni Sport Short Stroke Shock Inserts, T3 Coilover Components and your Spring choice!

We offer store credit for your old strut casings as well! They must be in unmodified and in good useable condition to recieve full credit.
