I have a 53 plate MY03 bug eye WRX STI non DCCD
Gearbox code as photo below. I can find out from data sheets that the centre diff is a viscous type and front diff should be an AP suretrac. But I can't find out the rear diff spec ? The rear diff doesn't appear to be an LSD as when you jack it up and rotate a wheel the opposite side wheel turns the opposite direction.
The car has been built as a rally car and I bought it with a lot of unknowns.....
is the centre diff and front diff any good for stage type rallying ? Can you get a rear LSD quite easily ?
Any help greatfully accepted
