Arbs's will make it even better. I ran coilovers with standard arbs and still had some body roll issues on track. Replaced with eibach arbs and couldn't believe the difference. The car corners almost level with minimal body roll.
It's worth bearing in mine that the stiffer the car the more likely it is to understeer or oversteer in wet conditions. It will still do this in the dry but much more likely in the wet. My car is set up for the dry and is an absolute handful to drive fast in the wet. This is a combination of my wheel allignment, shocker adjustment and arb setting, along with the roll cage make the car even stiffer.
