posi or spool?

[UDLOSE]

Just want to know your opinions on this. Car is a mid-low ten second car, driven on the street maybe 300 miles a year, track 5/6 times. Engine 109 2 main caps stock crank/rods, TRW .20 pistons, GN1 heads, 215/220 roller cam, 70 p trim, PTE front mount, etc. Billet trans w/ manual trans brake. probably upgrade driveshaft when doing rear. So let the opinions fly.

the spool

is real hard on axles when turning, but it is the strongest!
either way consider up grading axles too! like 30 spline or better.

I have some friends that drive a bit with a spool. For 300 miles per year, I think you'll be fine if you need it.

Locker, and put up w/ the cliking and the jerk...

Eaton makes a rebuildable unit for $420.

The only way I'd go with a spool is if you hang the hoops past the 60 ft mark.
