need to know what diff oils run on a clay track. I am new to the sport and dont know the effects of diff oils any help will be appr. I run a MBX5 thanks [8D]

It`s hard to say , it depends on track conditions . For the best answer try talking to a few locals at your track , they will be able to put you in the right direction .

if u're newbie, why not scroll back or look back all the thread..a lot of ur answer is there.. plenty of this issue is asking over and over again..

First try your car and see how it feels on the track.
Then you can move from there.
Does it spin a lot?
Which tires?
Do the front wheels spin a lot when exiting a corner and the car doesn't accelarate fast?
Does it understeer,oversteer,...?

BUT first set the suspension right and then mess with diff oils.
Make sure to at around 1 degree toe out at front and around 2-3 toe in at the rear.
NOTE that the rear toe in is very sensitive.MAX 3 degrees.More toe in=less oversteer.

10,000 in the center 7,000 in the front and 3,000 in the rear is a great place to start

Front- thicker gives you less steering responce off throttle and better on throttle "posi" traction pull out of corners because of the even power to both wheels... lighter oil gives lots of off throttle steering responce because there isn't a lot of resistance to how fast each wheel spins but less front wheel bite out of the corners because the power gets thrown to the wheel with the least traction.

Center- thicker gives more 4wd which can give you some under steer on a high traction track because the power to the rear is pushing the front tires (thicker oil will make the rear loose on low traction tracks while on throttle) but great drive with all 4 wheels accelerating the buggy hard... thinner oil will give you a lot of power to the front wheels so it pulls the buggy around on the throttle giving you good on throttle steering but lacks a little acceleration because mainly the front tires are pulling instead of all 4 digging.

Rear- thicker will give you understeer off the throttle because of the resistance between each wheel spinning to the other but if you do break rear traction both tires will be getting a lot of power making the rear of the buggy loose, thick oil can make handling a little inconsistant because of that... thinner oil will give you quick steering because of the low resistance of how each rear wheel spins and it will give you a hard time to break both tires loose because all of the power goes to the tire with the least traction which is the inside tire. To light of an oil can make the rear of a buggy feel loose everywhere.

A good base setup is 5k front, 7k center, 3k rear. Your diff setup probably wont be perfect on your first try so thats why you need a good base. After you drive the buggy and find out what changes you want to make to its handling then adjust it accordingly by using my info above. Diff setup in my opinion is the most important to make a good handling buggy. Tires being second because if your diffs aren't working correctly then a buggy will never handle right no matter what tires you have on. Suspension setup would deffinatly be 3rd most important and its very simple compaired to setting up diffs. Just take your time and ask for advice from the locals at your track.

I'm a bit of a noob but in the past I've had 5000 in the centre and rear and 3000 in the front, works well on most tracks Using 5000 in all 3 diffs atm in my Matrix but yet to take it to a track.

Do not overfill the diffs!!!! Only to the cross pins. Overfilling with 3k diff fluid is like using 20k filled normal.

I have a new ofna set up.. mbx.. whatever came stock in the diffs is what is in it.. The problem i have is on full throttle seems like the rear end of the car is going all over the place.. any suggestions?? Is it my wheel setup or do i have an oil/diff problem??
