We have a range of flywheels for performance engines off the shelf. These are lightweight ones.
We can do solid replacement flywheels for engines that come factory with the dual mass one and we stock Toyota 1UZFE flywheels to suit different clutch combinations.
We can custom make flywheels for guys adapting engines up to different gearboxes. If you would like anyinfo please email firstname.lastname@example.org
One that I thought may be of interest is one that we have recently developed after being asked so many times. It's for the Nissan Patrol TD42 Engine. We have them available for both turbo and non turbo (different bolt PCD) $599 to you guys.
