I raced an Astute once. I borrowed one when my Ultima was grounded due to lack of spares for a meeting. My friend generously suggested I take his Astute out instead as he was racing 4WD.
It was an odd beast and no mistake. No matter what I did to it, either whilst driving or setting up, it simply would not do anything but understeer and understeer badly. The Ultima would flick out on demand if you set it up right, and handled more like a 4WD car, but the Astute just wanted to go straight on. If you could turn in early enough and feather the throttle through the corner, it was fine, as it had an extremely low centre of gravity and was as stable as anything. In tight infield sections, it just didn't want to know.
The only thing I can think of was the fact I was using a fairly mild motor, because my cells were old and couldn't take anything really potent without dumping. It could be that with a louder wind you could break traction and balance the tail on the throttle through corners. But in my experience, you couldn't slide it, drift it, roll it or do anything with it but serenely and calmly understeer. It was so stable it was almost dull.
It's been a while since I saw the gearbox end of one of these, but if it's got the set-up I remember, with the two drive belts next to each other in the drivetrain, then one of the set-up tips at the time was that one of them can be safey removed. I have no idea why they put two in, as all the second one adds is friction.
If I'm thinking of the wrong car, and there are no such belts, then ignore me and I apologise. As I said, it's been a while since I saw the business end of one of these.
