Now I'm on to the rear axle.
For months I’ve been vacillating back and forth over the rear axle and couldn’t settle on an open or locked diff, not to mention as well, quick change vs fixed.
I’m also concerned with roadster’s drivability and to my rookie eye; roadsters appear to a bit nervous (like me).
Therefore, I’ve listened to Sparky promote Torsen diffs, watched his video and I’m thinking he’s on to something. I’m convinced he’s right and thinks the Torsen will apply traction to the tire that needs it, which should settle “some” of a roadsters tendency to dart around. So I’m going with a Torsen diff.
I borrowed a 7.5 inch 10 bolt for mock up and axle length. And I’ve talked at length with my local diff shop (JS Gear) and they have a Torsen series 2 from a 1999-2002 Camaro and a 2.28 gear. They suggest upgrading to Mark Williams race pieces, new 3 inch axle tubes and Ford big bearing ends, as well as Currie custom axles. All reasonable recommendations. However I’m not sure this will be strong enough to handle 1000 high horsepower.
So would anybody know whether there’s a Torsen that will fit an 8.5 inch 10 bolt, as well as to whether there’s an acceptable 2.28 or close gear.
