This is what i came up with to even the balance. Not shown in pics are two new 2mm shorter outer battery stoppers in 2.5mm cf. Identical otherwise to the originals but shorter. Made the holes 2,7mm so I could set the screws directly in the cf without a nut. It works and it is rock solid.
This moves the lipo 2mm closer to centre.

Pic1. A 1mm thick cf plate witch is 5mm wider than the chassis so electronics can be mounter further out. Only one hole shown in this pic but I made two so both holes in the chassis secures it firmly. Also used the hole in the servo mount so everything is one piece.


Pic 2.
With electronics mounted


pic 3
Shows the 0.5 mm space between chassis and tray. The tray doubles as a battery stopper inwards also.


pic 4
Tray mounted in the car.


The idea is to even the balance and now my ride weighs race ready 1349g with a mazda speed 6 Lw body and the balance is perfect. Got space behind the esc for a motor fan that will make race weight legal.
Another advantage with this is the ease of maintenance in case of a quick chassis swap or some soldering work on the esc. It does not affect chassis flex either.

Your thoughts?

thats pretty cool, except you effectively made the chassis thicker by bolting it down in more than one spot and changed the way the car flexes.

Can you just use the one bolt to the servo mount?

I dont trust the single bolt in servomount It is only 1mm thick cf. A hard crash could snap that right of so I used two holes. Dont know what they are called in english but the aluminium bushings got some more play (3,25mm inner dia) around the screws and the nut is tighten not all the way on top of those. Not to the cf at all. Look closely at pic 3.
So I understand what you meant but I thought about it in advance. So the tray moves along with the chassis just fine

Thanks for your input!

Has anyone tried shortening the front wheelbase on asphalt? What did you notice? I did this and it made the car more stable. Am I missing something or did I do it wrong?

I wonder how accurate this is:

The photos that are with the setup sheet show shock positions 4 front / 5 rear, Also the short ball studs are used on bulkheads. If the picture is of the car he was running...

Also standard towers standard length shocks are being used, thought they may have kept the shorter ones.

From these pics, the car looks to have regular shock towers and shocks

I loose a little of front bite and made the car push a little. I use it more of weight transfer thing than wheelbase. But thats just me.

Front:
Arms are moved forward.

Rear:
Stock shim positioning

Therefore, I have it set to long.

You probably already know this. If you move your arms forward, this changes your ackerman. So adjust accordingly.

Sounds good. I'm going to try it on carpet this weekend. Our carpet is like really picky super sensitive asphalt. Come down and race with us! BD7 s are dominant especially Berger and Mejia's.
