Default diff settings? i keep loosing control.

i have a NTC3.. ver.2, and no matter what wheels and tires i run, once i get about 70% throttle, the back end starts to wonder out and throw me into a spin.

im running my rears as straight up as i can see.. 0d toe.. and

should i be running a 1, or 2d toe? and what precentages should my front and rear diff's be?

i think im tight in the front, and loose in the rear.. whats going to give me a straighter line?

thanks all.

I run as much as 3 deg of toe and up to 4 deg of camber to get the rear under control sometimes. I would not run you diff loose just to stop the rear wheels from slipping. Rebuild the diff and keep it tight enough to keep it working and not slipping.

Sometimes we run the diff very tight so it's closer to acting like a locked rear end.

If you run a lot of camber you will need to run the car some to get the tires to cone some and you will feel the traction coming up in the rear.

What rear tires are you running?

thanks for the advise, im running almost 0degree everything.. and a high ride.. 2 thick spacers in the shocks.. i for the parking lots, i need alot of road clearance.

so tighten up the rear diff? see thats what im not too sure about, i guess i'll tighten it up.. the book says a tight front diff.. and a loose rear end will provide as little steering as possible.

i want to be able to run top speed and in complete control.

so after thinking things over, i think the best idea is to run 1 or 2 degree tow in, and 1degree camber.. remove a shock spacer, and hope to soften up the suspension.

im also running new associated wheel tire combo.. and even tried some HPI advan tires.. new everything, and the back end kicks out.. so it has to be my suspension.

They are talking more about going into a turn on a race track after you are already at speed.

I sent you a PM.

Start with the standatd setup in the back of the instruction book or the optional for foams. If you don't have that go to AE's website under setups.You need the setup tools, hope you have them. The stock setup is actually a great starting point. More rear toe is needed to control the "on power loose condition". Also check the drive cup from drive shaft to front diff isn't broke. PN 2270. This can go bad causing only rear wheel drive. Check by lifting and turning rear wheels while PRESSING down on front to see if the front wheels turn. We have broken this a few times and visually it appears OK until you test it. You have to put pressure on the front cuz I've seen it still spin the fronts until you put pressure on the front.

The body is the difference. Nice looking car, but it needs the wing for high speed downforce.

The big bumper also traps air. You may want to consider another body that the racers use. If you take a look at a racers body in the back, they cut the rear bumper as high as the rules allow for.

You are asking for alot by running on that kind of surface cuz I know. We try to practice on that between races and its no good. My advice is standard setup with rear diff extra loose and use throttle control. The tighter the rear diff the more its loose. So go "tight front and loose rear "diff settings with the softest tires you can get. Foams at 35 shore.

If it has loose dirt on the parking lot it is always going to spin the wheels. Yes, a rear wing makes a huge improvement.
