I have just changed the diff in my BA Wagon from the standard 3:23 Ratio to a 3:45 Ratio and had a LSD fitted the car drive's about the same as before very slight differance in the way it accelerates there is a small improvement nothing big i was going to fit 3:73 gears that I had but was told by the diff place that reco my diff it my rev to high at 100K's on the Highway and also they may be a bit noisy. The diff in the Wagon is a Dana 78 series (0578).

Did a lil burnout the other day, found out my car is LSD stick! Stocked!!
