Let’s talk about the 8-1/4” diff

if you're rolling on 400 treadwear tires i don't even think i'd worry about it, especially if the hit is from a roll after the shift.

not an apples to apple comp, but i had an 8.25 under the dart with 3.55's and abused the **** out of it side stepping the clutch on the street and banzai runs at buttonwillow, the springs and a bunch of autox.

i'd say if you keep the one wheel peels to a moderate amount that it lives just fine for awhile.
