Rear Toe IN-Toe Out?

[billy-bones]

I know the stock slash,comes with 3 degrees toe in for short coarse control.
But how much would that toe in,take away from top end speed,on hard surface,drag racing?

Drag racing a slash?

I guess I was just wondering if it could have anything to do with the fact,that my stock slash smokes my mod with pro line trans,every time.
And not by a little. I'm wondering if the pro line was a wast of money?

In any of my speed run setups, I would set the toe to zero by running flipped 1.5º bearing carriers. It does make a difference. Slip angle gets skinny-- when the truck goes to step out at speed, you generally won't be able to catch it. But you will pick up a few miles an hour in the top end. Now if you're trying to do anything other than go fast in a straight line, keep the toe-in.

Thanks,I keep one for more flat surface speed running(stock trans)and control arms,with -1.5 toe, with tekno axle carriers.The other is for short course,that's the one I run the pro line trans in.I got rpm rear control arms,with+1.5 degree toe, Tekno Axel carriers,not sure if the rpm come with preset toe in? But both 3500 velineon set ups,the stock trans stomps it.Must be the toe in on the pro line?

That's one sweet rig!! ow some heat sinks,got to have m.
Where do I get a set?
And what pinion to spur were you running to achieve those speeds?
