yeah but rally-a-coupe you still dont want mass amounts of body roll cause that aint good either, you need to as much as possible keep the weight evenly distributed (why i bought a 1200 as it has natural balance and light weight) on all four tyres as this will achieve maximum traction (going sideways is cool but aint always fastest). for this reason i reckon keep the front end flat with sway bar AND strut brace to reduce understeer but leave the arse end as independant as possible (i.e. as much like IRS on 1600s as that is a very good setup and the reason why people rally the 1600). the thing to watch out for with sway bars is though that if you upgrade to a really stiff one you will achieve better traction but also increase unpredictability as when you do manage to break traction the car becomes a lot more difficult to control.
thats my 2 cents anyhow
