Thinking about shimming the drivetrain up 1mm in order to flatten the driveshaft angle. Can I expect more traction or less. Never used this adjustment when I had a conventional TC so was considering giving it a go. Anyone who knows what effect raising the diffs has please chime in.
Tony Tam did this at TITC
I've been running HUGE ride heights outside which does the similar change. 6mm front, 6.5mm rear

The higher positions gives me flatter car + more responsive car. It feels like it yields more overall traction > looking at the rear of the car - the driveshafts have a much less radical angle. I havent tried the same car on carpet but on low/med/high bite asphalt the car has been a contender.
In addition to other explorations like running higher ride heights, softer chassis and t-cut top deck the cars have been awesome (pun here!)
Good luck!

The best mousetrap so far is:
R1 sells this unit. Buy the unit, run their fans or another. Dont look back. I have ran the same fans since November with this mount. You can still side-mount it if you want or rotate to the 10 o'clock position to get them out of harms way.

I also tried EVD driveshafts in the rear vs the standard driveshafts. The EVD appeared to make the rear more predictable / easier to drive and yet adding some corner speed. That being said, the conditions changed so it was hard to come to a confident conclusion.
I think it is worth exploring more and it appears Mark has had good luck raising the drivetrain too during an extended period of testing / racing.
about the video : every few minutes or so there will be a title overlaid explaining the changes made to the car during each segment.

Mike, Jake and Mark - Thanks for your prompt responses, it means I can do this job today - and sorry for the long post, I just wanted to explain where I'm going with this.
I'm making a 2mm chassis so I can lower the car by 1mm for the same ride height. It should bring the overall weight down with BRCA tyres (+LW SP6), and increase flex but without using the cuts which (might) make it smoother to drive. Last year I milled down an old worn plate to 2mm and quite liked it.
The main concern was the thinner plate will steepen the driveshaft angle, and by your responses this is definitely not good. So I'm going to add 2mm underneath the drivetrain so its 1mm above default. As a bonus I wont have to cut a recess for the motor which means the chassis will have even flex throughout.
Yesterday I started on the chassis, and milled down the shock brackets to reduce the required recess to 1mm so the chassis doesn't wear out too quickly.

Hi all,
can someone insert pictures that explain how to install the shims under the drivetrain and how it affects the assembly of the car and the upperdeck in particular?

Interestingly while chatting to Awesomatix owner & designer Oleg Babich over lunch he told me they are set to enter the electric offroad market potentially next year. Breaking the design trends with his A700 touring car, Oleg said so far he has only had time to put together some rough design ideas for the buggy but asking him if it would feature his unique damper design he said it would as he wanted to come to he market with something different to what is already on offer, a formula that worked well for the Russian newcomer when it entered touring cars.

ROAR Region 2 asphalt series wraps up tomorrow @ MRH, Awesomatix USA will be there in force

If anyone tries this , just don't forget to reduce the number of shims under all the inner "camber/caster" ( upper ) links to maintain your current setup.

What do you guys do setup wise on asphalt when the track gets hot? Like 140F plus.
#3929
If you arent running spec tires, go up 1 shore 30s to 36s, etc.

We have ran most of the summer with 135+ track temps. Our cars tend to stay more consistent in the warmer temps with the dampener design.
