I've got a RSK B4 and from what i've researched it's apparently between 1400-1500kg curb weight, in saying that, mine may very well be a litle heavier than that with full leather interior.
Also trying to compare the RSK and WRX together is not logical, The RSK is a family sedan whereas the WRX is built for rally/speed so ofcourse the WRX will have more torque than the RSK and reach a top speed quicker due to short gear ratios, but having longer gear ratios it would make higher top end?
Does anyone which has the better top end? RSK or WRX?
