Heres one I haven't seen. Even tried to search it. I have an 88 Formula that I autocross and do minimal Time Trial events with. I have installed a OBX LSD unit into the F23 tranny that is in the car approximately 5 years ago It has proven to be not as effective as desired. New belville washers and bolts installed as directed prior to install and removed and checked once after the second season of use I am wondering if welding/locking the diff would be an option to totally illuminate one wheel spin? Has anyone raced their F23 equipped car in this type of competition with a locked diff? Would the tranny survive? Worried about the potential to understeer? Also for FYI, tire choice is currently Hoosier A7 245-40-17 at the rear

It would seem a welded differential would cause 1 or both of your rear wheels to drag in the turns or break something in time. A limited slip differential would be better in my opinion if its traction your looking for.

I had a welded diff on my 4 speed 4.10 Muncie and I loved it. It requires more of the driver to steer the car but you can put the car where ever you want and throttle steer it on the path you'd like it to go. When braking from high speed (100-120mph) the car is very stable, it doesnt wander left or right. You axles will wear out quicker (play between trypods and hosings) I now have a limited slip made in Serbia. It behaves just like a welded diff but I don't have the hopping while making tight slow corners. So, if you ask me if I recomend a welded diff for the track? I'd say yes.

Acceptable idea on a road race car, but bad idea on a slalom car. A welded diff doesn't work well on a tight corner and also introduces understeer that is probably the last thing you need. An LSD or even an open diff works better on a tight course.
