If the UK STi7 has got a front and rear Suretrac diff, what's so special about the front one?

 

Because other UK supplied Imprezas (possible exception of 22b UK ?) have an open front diff not an LSD.

 

All other impreza's have an open front diff, I think that also incudes the 22b. AFIK Prodrive only changed the diff ratios on the UK 22b's

 

Ok, so what's a open diff do or not do then???

 

it wont lock up like an lsd type diff

 

I assume that an LSD slipping wheel will eventually stop then, whereas an open diff wheel will still slip as power cannot be completely diverted???

I don't believe this is correct. I understand that many Type R and Type RA cars were supplied with a front LSD unit.

I deliberately put "UK supplied" in my original post for this very reason, but it suffered from Chinese (Japanese?) whispers on its way down the thread....

 

I think front LSD's on all Impreza's before the UK STi 7 (with the possible exception), had an Open diff but with an option for a front LSD?

For example, Scott's STi 5 RA V-Ltd had a front LSD but it was an option (as ticked on the options list). Or was it just the on STi's that this was an option? (and presumably still is on the JSM STi 7?)

Dave T-S,

I actually quoted the statement I was quibling with and it sure wasnt your one.
