My L4
tends to oversteers a bit when i exit the corners (low to medium
speed corners), is there anything i can do to minimise/fix this?

For Asphalt:

RC12L4

5 degree block

2 caster shims forward

Change to one in front and one back

Camber approx -1.5

Change to 1 deg then check tire wear you need to set this so your
tires wear flat

Toe = 0

This should be ok. I run 0.5 toe out

T-Bar: AE Thin one

This is good. I run all 3 pod mounting screws with a green center
shock spring

Damper Disc lube:

Try some diff lube. Get some teflon tape and put it on both sides
fo the top pod plate. I bet this is 90% of your problem. I think you
are under damped.

Tyres: Jaco front purple, rear pink

Perfect

No damping goo on king pin

Try some Trinity "Red Stuff"

Dual Rate: 70-75%

Should be less than this. Sounds like you are pushing too

Steering Exp: -40%

I usually run this linear. Expo can mask handling problem. You
car should be smooth on center on its own without expo.

Front Springs: 0.22

I run .020"

Motor: V2 9 double

CA on tyre sidewall

This is really bad on asphalt. Only do this on carpet. This may
be a big part of the problem.

The CA on the sidewall is there
to reduce side bite. This is good on carpet to prevent digging
and traction rolling in corners but bad on asphalt. On asphalt
it will make your car push if the fronts are ca'd or loose if
the rears are ca'd.

Where are you racing? I have never heard of traction compounds
being completely outlawed. Usually you use an odorless compound
or a completely benign traction compound like suntan lotion.

If no traction compounds are allowed you might want to try
platinum compound rear tires for more grip.

On Asphalt you should use thin
suntan lotion as traction compound or Trinity Tire Tweak. Sauce full
rear and 2/3 of the inside of the fronts.
