ATI’s new Toyota Supra B58 flexplate is currently the only SFI version available for the B58
engine. The 915472 flexplate and 915082 crank adapter allow you to use your OEM converter
and flexplate bolts. By taking advantage of ATI’s nearly 60 years of cutting-edge technology,
we offer maximum concentricity for a high-quality, long-lasting flexplate that will not damage
All ATI flexplates are created from custom drawn SFI-spec steel and are double MIG/TIG
welded for additional strength and lasting precision pass after pass. They are quality inspected
to EXCEED the flatness and run-out tolerances of the OEM units and are precision balanced
on a Hines digital balancer to 1/10 ounce/inch.
