sold my track going impreza a while back now, since had a 200sx and RX7 but neither have felt like my WRX.

i want to keep with the rear wheel drive theme but in another impreza.

my problem is my budget wont stretch to a car with diff control but i also feel it would be a shame to strip out a perfectly decent impreza.

so im after an RA to get set-up for drifting.

question here is how do i remove the front diff's and lock up the rear without it being dentrimental to reliability ?

so can someone please tell me how to do this,or if you know how to ill come to yourself ?

many thanks

Paul
