I have  run my TR-4A (solid axle) in vintage racing for three years with the 
stock  differential with no problems until it lock - unlocked - and then broke 
 completely at Sears Point.  I am down to two choices. Another stock one  
since I like the way the car handled with the stock one or a Detroit locker  
which I understand works well if you are fairly smooth get your breaking done  and 
then accelerate  out of the turn without much on and off the  gas.

Any thoughts.  Reliability??  Handling??



Well Ron I agree with Bill in that the cheapest way would be to just go  back 
with a stock diff, & that the lockers can cause problems... so I will  offer 
option #3... weld the thing. Relatively inexpensive, no moving parts to  break 
or wear out, & dependable as you can get. You know exactly what it's  going 
to do, yes it will tend to push.  Set the suspension up  accordingly & learn to 
drive it & you can deal with that. Also consider  that the quickest way to 
the NEXT corner is to get the throttle planted hard as  soon as possible coming 
out of the previous corner. With an open differential,  once the inside wheel 
lifts, it's all over. Some lockers get funky through the  corner but ideally 
one shouldn't be lifting in a corner anyhow, unless you're in  way too hot, & 
that often results in problems far worse than the  differential failing to 
differentiate...
It WILL be a PITA to push around the shop/paddock though.
