changing the chassis seems a bit extreme just to cure a loose car...

Id start by taking some of the steering off the front end as you probably have way too much and thats whats making it unstable on the back end.

Also you havnt pointed out whether its on power or off power your struggling with and on what surface

More info as tom says please!

What surface are you racing?

What tires are you running?

If you could post your complete setup and name/post pics of the track it would help

my point was that the OP stated the rear kept breaking away and without asking any details you suggest he spends £71.98 on parts...

I have lots of suggestions towards reducing the car breaking away, but as Tom pointed out more info is really needed.

Right...

I'd suggest trying stagger ribs on the front, if you haven't already. They make the car much easier to drive and more predictable through the turn, whilst keeping plenty of turn in.

After that my suggestions would be:

- Stiffer front spring and/or move to the outside hole on the front arm
- Front uptravel limiters, ~2mm
- Try changing wheelbase. Depending on your driving style longer or shorter could work.
- Check ride height is ~21mm front and rear. If the tracks not too bumpy try lower it down a couple of mm front & rear.

I appologize, I just didn't want to see this turn into another brand trashing thread....nothing but hate comes out of those.

I never heard of the rear slipping out on a carpet surface so I assumed it was on dirt....

Thats why some of us are club racers and others are factory drivers.

Have you checked your diff? If the diff is "dead" your car will be loose in rear end.
