I have been running Nitto DR's at the track and still can’t seem to get any traction. So I’m thinking about trying some ET Streets but I really don’t want to break the rear end or burn clutch packs up.

What kind of life expectancy will I be looking at on a stock 3.23 rear-end “98 with 63k on it” Will I need to get a rear end cover “like the T/A or Mac” fluid change? If so what’s the best fluid to use?

Mods are
Fastoys ram air
Direct flow lid
Bkk 80mm tb,
Hooker headers
Hooker y-pie
Slp loudmouth
Build 4l60e

i will be add a cam and ls6 intake this winter so i will be hurting for traction even more next year
