Thumbs up Clay oval beginner set-ups!!!

Is there a site where a racer can find out basic set-up info for a truck. I just started racing a Losi XXXT on clay oval and having a hard time finding what works. Not sure of hard or soft springs or mix and match. Shock oil weight. Ride height. Any elp will be appreciated!

Default Talk to local racers....

Without knowing how the track is configured, your best bet is to check out the local fast guys (or gals) at the track you are racing at and see what they are running (tires, shock oils, etc). Any of them should be glad to help you..

They will be able to tell you better than people on a discussion board who may or may not have seen the track in question....

Default hey, thanx

Have talked a bit with the kings of the ring. But they are a bit tight lipped when it comes to the key set ups. I just need to find out what does what to the chassis. Not familiar with oval set ups. Its easy to look at the tires, but as far as springs and what they do on an oval, I lost!

as for springs


stiffer right rear= car turns more or becomes loose on exit.

stiffer left rear= car turns more on entrance or becomes loose on entrance

stiffer front springs less turning.

now if you go softer the opposite will happen.

as in softer front springs the car will turn more

Default useful information

(found this on a website a while back thought id share it here)

The Handling Guide

Directions: Do one of the following change to your vehicle at a time and drive test.
Keep good notes (It's hard to do at the track but try to keep a log it really helps).
Also, don't forget to have fun....

Phase 1 (going into the turn)

If the vehicle is loose at turn entry then..(needs more traction)

(1) Right front spring is to soft use a harder spring
(2) You need to add more crossweight - by adding a round to the right front spring (add weight to the left rear tire).
(3) Change left front spring to a softer spring.
(4) Lower chassis - keeping it level with the rear.
(5) Reduce front right caster (no less than 2 degree min.)

OR If the vehicle is pushing into the turn entry then..

(1) Right front spring needs to be softer.
(2) You need to reduce the crossweight - by taking out a round to the right front spring (add weight to the front left tire)
(3) Increasing right rear spring tension by one round
(4) Increase front right caster (6 degrees max.)

Phase 2 (the middle of the turn)

If the vehicle is loose in the middle of the turn then...(needs more traction)

(1) Increasing the crossweight by adding a round to the front right and left rear evenly (add weight to the left rear tire)
(2) Use a harder spring to the left rear
(3) The right rear spring needs to be decrease a round (less spring tension)

OR If the vehicle pushes in the middle of the turn then...(needs more steering)

(1) Decrease crossweight by taking out a round to the front right and left rear evenly
(2) Use a softer spring to the right rear
(3) The right rear spring needs to be increase a round (more spring tension)

Phase 3 (coming out of the turn..)

If the vehicle is loose coming out of the turn then..(needs more traction)

(1) Stagger needs to be decreased on the right side
(2) Increase crossweight by adding a round of spring tension to the right front and left rear evenly (add weight to the left rear tire)
(3) Check if right rear spring tension is to much - if it is then take a round out of spring.
(4) Decrease rear springs evenly to the right and left rear.
(5) Use a soft tire in the rear

OR If the vehicle pushes coming out of the turn then...(needs more steering)

(1) Stagger needs to be increased on the right side if present.
(2) Decrease crossweight by reducing a round of spring tension to the right front and left rear evenly (add weight to the front left tire)
(3) Increase right rear spring tension a round.
(4) Increase rear springs evenly to the right and left rear.

Default great answer, thank you

Finally an explination I understand. I truely didnt know what did what to the trucks handling. This will help a lot as to what the truck is doing. At least now I can try to get through the turns and not spin out every time. Wasnt sure what to do. My adjustments only seemed to make it worse no matter what I did. Will be going to practice in a bit and will let you know how its doing.

Default wow

Thanx Viper, have raced 2 times using the set-up guide you posted. What a difference it made. Still working out the set-up but, have gone from pissing the other drivers off to holding my own. No spin outs in the middle of the corner. Now need to work on my left index finger (throttle control). went from20 laps to 34 in two weeks. Once again Thank you.

u can also space rear hubs left side forward and right side to rear. ie shorten left wheelbase will help on exit push , left side will pull more on power out of corner

Default tire trick

i used to run a XXXT on a dirt oval and i found that the stock truck tires have way too much side wall roll.

so a trick i learned in get your self some new truck wheels and some buggy rear tires, i used hole shots, put the buggy tires on the truck wheels. makes a nice low profile tire with almost no sidewall roll and it looks awsome. make it look more like an oval car then an offroad truck,

another tip: glue one side at a time ( may sound like a DUH commet) but it its not 100% dry the tire will pull away form the wheel. when the one side is done just strech the tire to the other side and glue it, you will need to hold it for a little bit or a few rubber bands

crashking, it helps to know what type of track you are running on. Is it clay, dirt, something else? packed or loose, does it stay together or fall apart throughout the day, is it glass smooth, wavy, bumpy, or worse. what are the generic tires of choice? dimensions and runline of track? is it oval, paperclip or other??
