I keep thinking that my car seems rather tail happy if I provoke it. I could quite easily donut it in the dry if I lanched rapidly with some lock on, and have tail slid the car out of junctions when in a hurry (semi deliberately).

In the wet i can provoke power oversteer in 1st gear no problem, and just in 2nd if on boost.

SO, i am wondering if the Legacy box has a different centre diff, uprated over the normal impreza turbo one. I've heard this mentioned once before in a thread, but didn't believe it.

can anyone confirm or deny?

Paul,
I've heard that all Subaru wagons both Impreza and Legacies have rear biased torque split (33/67 or 40/60 I'm not sure). I know for a fact that my 2nd gen Legacy GT wagon has a rear bias 'cause I've a RR printout with separate front/rear power curves to prove it.

My Impreza wagon could also be a bit tail happy in the way you describe so I think its a wagon / saloon issue rather than Imp / Leggy issue.

Ive never felt that way about my car. Oversteer can be provoked, but very rarely power oversteer. Only by letting off, or throwing it into a corner, usually in the wet. In the dry its understeer nearly all the time. Dry trackdays are boring, wet trackdays can be fun though. I also changed the rear anti-rollbar for a saloon car one, which is stiffer, to try and loosen the rear a bit.
Any slight tendancies it may have to oversteer, are due to the extra weight getting thrown about at the rear of the car I think.
There was no noticeable change on my car, even after I changed the box for a UK impreza one, after mine had a disagreement with a 6Krpm launch.
Do you have the same tyres all round, as this can make HUGE difference.

 

Paul, do you know what suspension Geometry your running? Or what about tyre pressures?

Two reasons I say this, my old suspension set up (on a UK Impreza saloon) - with about 1 degree each side negative on the rear 1.5 each side on the front and 7 mins toe in each side front, 5 mins toe in each side rear - was very power oversteer biased...in any gear except 5th!

On the tyre front with too low or too high pressures at the rear it does want to move around a fair bit!

Anyway I'm not surprised it will oversteer with lock on from a launch

 

Tim,

I don't know the geometry off hand, something like 1.2' neg camber front and 40 toe in (is that thou or minutes? done at Leda).

Anyway, if I do give it some when pulling away from a junction, the front inside wheel doesn't spin.

Same tyres all round, Kumho 712, 33psi I think, might have set the rear at 31psi, was a few months ago that I checked.
