- Team Associated RC12L4 - Advice to minimize/fix oversteering - 09.08.2005 -

 

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.
