akane and all fours are pretty much right. st185's , well my one did and i have heard similar comments from several others , are prone to unpredictably switching between under and oversteer.
you would be doing very well to hold a slide for any length of time in one. its been a while since i had mine, but usually it would understeer first, then flick into oversteer very quickly and it pays to be prepared for it. the best i could ever reliably get it to do was stick the tail out briefly and pull it back in. if you're not fast enough youll find yourself facing the other way.
it might be a bit different on gravel and grass, but i did a grasskhana in my one and it was still a bitch to predict what it was going to do.

if you get on a track i guess youd wanna try and stay smooth through the corners and dont throw its weight around too much

Quoted from http://www.nsxprime.com/FAQ/Track/highperfdriving.htm ...


website wrote:The following steps can be taken to decrease oversteer (increase understeer):
[PM]

increase front tire pressure
decrease rear tire pressure
smaller front tire section
larger rear tire section
more positive front wheel camber
more negative rear wheel camber
more front wheel toe in
more rear wheel toe out
more negative front wheel caster
stiffer front springs
softer rear springs
stiffer (heavier) front sway bar
softer (lighter) rear sway bar
more forward weight distribution

The OPPOSITE of the above will decrease understeer and increase overrsteer.


There are far better cars you could choose to take to the track than the GT Four, especially if you want to get it sideways. If you're going to stick with the GT Four, then it needs to go on a serious diet (as has been stated), and replace the sway bars. A stiff rear sway bar from Whiteline is highly recommended by most GT Four entusiasts as being very helpful with reducing understeer / increasing oversteer.

(a little off topic)

what would happen, if you ran a different ratio rear diff on a 4wd car?

So the output ratio to the front and rear wheels were different?

Punch the clutch if you're feeling crafty :lol:

You would kill your centre diff quickly. Imagine running different sized wheels on either side of a RWD or FWD car.

Very very twitchy car that gets worse with speed. Its common to do this with offroad cars, it makes them turn in quicker. However it severly limits their top speed, for all enduros the diffs are pretty much matched. (and remember this is on a "non grip" surface!)

I found the handbrake was the biggest aid to getting it sideways in a useful fashion on grass - in my 185. Not great for the handbrake, mind you... (foot down in second or third gear driving all four wheels while handbraking the rear pair... heh)

Theres some shots of me doing it in the video from the Auck/Ham Grasskhana a coupla years ago..

hhe, my old Corolla(85 1300FWD) would smoke up the Kellys... man... they sucked as tyres.

Saw a Mazda GTX on a skid pad with space savers all round, it was the most putrid smelling smoke that I've ever smelled.
