Subaru is going to run the Isle of Man TT course in a near stock STI, just tires exhaust, brake pads and roll cage, at least that is what they are claiming. Already lapped at 113mph in practice with brake fade issues on a downhill section. Mark Higgins, rally champion and Isle of Man local doing the driving. Official run scheduled June 10.
Sidecar record is 116mph for comparison. "Sidecars" are like mutant 3 wheeled GP cars with two men on board- powered by a 140hp 600cc bike engine. Not like any sidecar you see on the street. The nearest thing to cars running the TT (regularly).
