Try shimming the front arms forward and the rear arms back. Then shim the rear uprights all the way forward. That gives a longer wheel base and moves the rear tires more towards the center for more rear traction.

Also try 5,000 center diff oil. And tray 400cts in the rear shocks for more rear weight transfer. And limit the rear down travel so there is less weight transfer to the front. And use the lower inner camber link hole in the rear tower. You are using the upper hole which provides the least amount of rear traction.

ok thanks i will try 400cst oil and the arms.rear downtravel is set to match the front.I thought that upper hole in rear camber link gives more side traction in the rear??Also can you explain me something?Everyone use fast and torque servo for steering so i purchased a new steering servo with 0.008 speed and 13kg torque.In the track the steering was so fast that i forced to reduced turn speed from my transmiter a lot.But i did not reduce the return speed.Should i reduced also the return speed??How drivers managed to drive with so fast steering??I want the car to have smooth steering.One more question titanium screws bent easier than steel screws or the opposite?

I use high torq servos, I do not like high speed servos.

Titanium is much weaker then steel but lighter.

What other bodies will fit best on the BR6 2.0 ?

What companies make option parts for the car?

I've fitted the bitty force for the 808 xray. Others use mbx6/7 bodies with good results.

Vp pro has some shock pistons and springs. Intech has a variety of hop ups. Check out dialed rc for all the intech options and parts

What sort of things would be worth upgrading out of the box?

i use jconcepts silencer body for mugen mbx7 fits very nice

Short rear arms & offset uprights, lightened outdrives, pistons, bladders, and springs are the most important.

proline phantom body for mbx7r does not fit, just a heads up so you don't buy something you can't use.

If you use the Optima flexible body mounts, any MBX-6/7 body will fit. You just have to cut it out differently. Mount before painting it.

It ended with a XB9 from Sweep Design and it looks like this.
