Are there new rear swaybars for ther 2.0 kit? I did the rear end update and the original bar seems alittle short.

Decided to run the uprgade without testing put my setup from prior , I was pleased. Made some adjustments after the second qualifier was able to place second in the amain. Biggest improvement was rear traction. Had a ruff start during the amain and a flame after a refuel was able to place third. Also noticed the rear shocks need lighter oils from t my prior setup because it has more volume. Need to redo my oils had allot of chassis slamping was sure how the new shock setup would perform went to light. Overall this is the best upgrade someone could buy for sure.

It sounds like you need to get a smaller hole piston in the back. The lighter oils will be better with the smaller piston holes. The new shock mounts are all the way out on the arm and the piston speed is increased relative to old mounting positions. More pack is what you need to help the chassis slapping. You can get more pack with smaller hole pistons on the lighter oil.

I'm actually running csi pistons very different from traditional pistons. Went with light setup just to get a feel since the rear has a different arrangement. All it needs is a bump up in WT and it will be great. If you haven't ran the CSI pistons its very different from your setup table verses when its on the track hard to make adjusmets without seeing what it does.

Which color csi piston and what weight did you end up with? I'm thinking about trying the blues with 40fr/35rr Losi oils. Think that's to light?

Thanks for that. I've got a set coming from AMain.

What kind of a difference in feel/ handling do you find with these pistons anyway compared to the stocker's?

And what setup would you use on a very low grip and extremely rough/ blown out track?
I'm 1 to 2 seconds off the truggy pace on my track right now with my buggy (no Serpent Truggies) and I would like that to change next season.

Just waiting for these piston's, my 2.0 upgrade kit, BCE chassis and the 2013 outdoor race season to start!

For low traction I would reccomend the red csi pistons, or at the very least the blues. They are designed for lower traction tracks than the blacks.

I am using the v2 red pistons in my TE buggy with 50r 60f oil front blue springs rear yellow. Might be a little heavy when the temps start to drop.

Putting on the new rear end for the Championship Race this weekend, will post results. I plan on trying both the blue and red pistons. Might drop to 55wt rear oil.

What is the major difference between the BCE chassis and the kit chassis?

Better wear, more steering, better rough and high speed track handling.
