RA23 Loves to oversteer!

Take off your front sway bar :-P.

so i was gunna start by saying "awesome!", but that's not gunna help...

sweet looking ride (looks same as mine, or same as mine should look when it's back together...)
my experience is yes, the 23's love to oversteer - one of the things i love about them, but normally it only does it when i want it to.

i presume your rubber is good all round, and you're running the same (or similar) rubber front and rear (and not new rubber on the front and old worn rubber on the back).

Nothing beats decent rubber. Worth every cent. It's what's between your baby and the road.

I would start by softening up the back, or making the front harder, or a combo of both, by adjusting the sway bars (assuming they are adjustable).
Softening up the back will have the effect of giving you more grip at the back.
Hardening up the front has the effect of making the back softer in comparison to the front, thus giving more rear grip.
Of course this is theory, and real life can vary.
Try different settings and see how you go I guess...

Also of course, don't make the car get sideways at all in the wet would also "solve" the problem - i presume you are doing that for the fun factor - not a good idea with hoon legislation these days

maybe a bit more practice of the go-karts? hehe

suggest getting into some legitimate motorsports to get the hoon fix you (and I) desire
motorkhana's are cheap, fun and easy to get into in a stock car.

umm, i'm no suspension expert, but wouldn't this make the front softer, thus giving more grip?
The front already appears to have loads of grip from the symptons described.

try it and see, try all sorts of combos and see what gives the best results.

For rwd cars you adjust the front harder to get more oversteer, fwd u make rear stiffer

making the front harder has the effect of making the rear softer (in comparison). This should give more rear grip (in theory).

i know wiki isn't the most reliable source, but it's pretty good

http://en.wikipedia.org/wiki/Sway_bar

Anti-roll bars provide two main functions. The first function is the reduction of body lean. The reduction of body lean is dependent on the total roll stiffness of the vehicle. Increasing the total roll stiffness of a vehicle does not change the steady state total load (weight) transfer from the inside wheels to the outside wheels, it only reduces body lean. The total lateral load transfer is determined by the CG height and track width.

The other function of anti-roll bars is to tune the handling balance of a car. Understeer or oversteer behavior can be tuned out by changing the proportion of the total roll stiffness that comes from the front and rear axles. Increasing the proportion of roll stiffness at the front will increase the proportion of the total load transfer that the front axle reacts and decrease the proportion that the rear axle reacts. This will cause the outer front wheel to run at a comparatively higher slip angle, and the outer rear wheel to run at a comparatively lower slip angle, which is an understeer effect. Increasing the proportion of roll stiffness at the rear axle will have the opposite effect and decrease understeer.

so harden up the front will create understeer, cancelling out the oversteer (that's the theory anyway!)

Increasing the proportion of roll stiffness at the rear axle will have the opposite effect and decrease understeer.

so decreasing stiffness at the back will increase understeer, which again, cancells out oversteer (in theory!)

So basically buy an adjustable front swaybar and soften it up should help?

give it a go if you wish, but i wouldn't. (but again - i'm no suspension expert!)
softer front = more grip at front, and you already have loads of grip at the front it would appear.

i would remove the rear swaybar if anything and try that first.

if that doesn't help, yes remove the front swaybar and see what happens.
trial and error may be the way...

hopefully there will be a few more opinions posted.

6 year old tyres may be getting hard too...

mate, maybe it's just the massive power you have, and with throttle it's just want to going to oversteer no matter what!

put bigger rubber on the back?
