Default Oversteer - how to reduce?

Hey, I've got a question - my truggy (LSP) very often oversteers and is very aggressive. Which settings do I have to change to reduce slides while exiting and in corners and to calm it down a little bit?

Now, I run:
rear camber 2* negative, rear toe-in 2*, 10k/5k/1k diffs, front camber -2*, front toe-out 1*.

I thought about changes in the rear - 3* negative camber and 3,5* rear toe-in according to Hudy Set-up book. What do u think about it?

thicker rear diff. 1k is just too thin for truggy

Thicker rear diff. Raise the rear upper camber links. Set them long if that is adjustable. (Inside hole on shock tower, outside hole on hub.) Softer rear swaybar. More rear droop.

Also, 3.5 rear toe is too much... yes, it helps keep the rear end from coming around... but when it DOES get loose it will do so more violently. Try maybe 2.5

NOTE: Try ONE change at a time, note the results, then go from there. And tires make more difference on traction than any other change.

Sometimes this can be adjusted from your radio. You may want to turn your exp. down on your radio. Try exp steering to -50 and go from there. It makes a big difference especially on slick areas. Slowing down the speed of your servos can improve the handling of your vehicle. This may or may not help your problem. Just another suggestion.

OK, so I'll try both - 2k and 3k in the rear. We'll see And also all theese angles and camber links as DOMIT says.

So far, thanks for replies!

Start with 5k and go from there... don't waste your time with 2k-3k on truggy.

Do I have to change the center, too?
For example 10-7-5, or just stay with 5?

EDIT: Tires are no problem, Calibers M2 on board

Change the center. 5k is way too soft for truggy. Start at 10k.

Check your droop settings. A ton of rear droop causes a car to "stand" on it's front wheels on corner entry (heavier front oil/springs helps this too). More rear toe will help on corner exit.

I run 7-10-5 in my XRay XT8 Truggy, and it works for me pretty well. I just adjust my camber a little if I want it to steer more aggressive and as long as I'm running good tires....it gets VERY Aggressive if I add negative camber!

I will try with 10-10-5.
I feel my car better in the corner with thicker front oil.

Try 7k fluid in the front diff. If you go with 10k up front you may go back the other way with your handling and end up with a push in mid corner and still have oversteer on the throttle on corner exit. (thicker front diff fluid increases on power steering) 7-10-5 or 7-10-3 is a good base for your diff oils, try adjusting your brake bias for more front brake to slow down the trucks rotation on the brakes on corner entry. Also, here is a link to the Xray/HUDY truggy setup book. It's the third down on the page and has alot of great information on offroad setup that will help you.

Yep, now i have something about 30/70 (F/R) and every brakeing action before corner ends up with a slide. I'll try to set it 60/50 or 70/30.

Could you also tell me basic angle settings for a truggy? I mean camber, toe etc.
Thanks in advance.

Wiktor, the best way to set your brakes is by feel, Start by dialing out some rear brakes and try driving your truck into a couple of corners to check the rotation on corner entry, if it's still too much, dial out some more.

For some basic settings,
Front 2 deg toe out 1 deg neg camber
Rear 2 deg toe in 2 deg neg camber

More front camber will make the steering more agressive, possibly twitchy.
More rear camber will also increase steering and make the rear slide over bumps and ruts better instead of catching the edges. Start with those settings and work on your brake bias. Let me know if you need more help.
