I'd hardly call that a shell "Not Marv".Weight split is different from sedan to wagon as the wags held 70kg more over the rear than the sedans. This doesn't change F:R bias much, but there is a lot more weight up high on the wagons. Also, it was the MY03-04 JDM STis got the better cradles for roll centres.
Anyone wanting a cheap Gen1 shell in NSW should keep their eyes out in about 12months time as an RS sedan shell will be coming up cheap. Might even have an STi RA motor, FMIC, 440s, 3" exhaust and parallel rails in it, too...

Paul, are there any tracks other than SEQ available to you. I know we have spoken about this, but it seems suckfull that there is nothing closer to you.
For the benefit of the others here, you may want to outline the opportunities open to someone like you to race and who does a bit remotely. Also how you expect to get your vehicle to the track.
