Ended up making my roadster a track only car and switched out gear and differential, Used in Roadster for 600 miles.
They were professionally installed and removed from Alternative Auto in Michigan. Still meet all specification, had Roadster up to 150mph and no vibration, $199 for both,
New at Summit close to $700 for pair

Let us know, how it compares to the clutch pak. Isn't the Auburn the cone type?

Excuse my ignorance, what rear does this fit?
If applicable, how many axle splines?

After making my Roadster a track only car I wanted an even higher bias torque, so I switched to the Auburn Pro diff. I like the design and engineering around this differential.
