Ah ok I see, I've not driven a car without powersteering before so it should be interesting
I see what you mean about going home, I think I would be very tempted to just boot it and see what happens on a clear track!
Most powerful thing I've driven is my dad's 840Ci Sport it's got just under 300bhp and humongous amount of torque but weighs over 2 tonnes! A bit of a boat round the corners! My brothers car is around 1300/1400 kgs and with the engine swap and modification it has around 220bhp, quite a quick one that
Dunno how much power our M20 engine will be putting out but I hoping for around 190, over 200 after the rebuild/stroke to 2.8 ltrs and a hairy cam so it should be quite fun
As for setup, your best bet is to find someone who can corner weight the car for you - with you sat in the driver seat. This should optimally balance the car for when you're driving - what they do (IIRC) is adjust the height of the suspension until there is equal load on each of the 4 corners. I would hope someone who can do that will be able to give advise on geometry setup and tyre pressure. Generally though (If im not getting this wrong!) tighten up the back end and it will over steer, tighten up the front end and it will understeer. So what you want is a balance between the two. Tyre pressures and damper settings are easier to do yourself as you can make adjustments, go for a drive then tweak further.
