To bring what I consider to be a perfect balance to the car which gives it amazing steering, corner speed and on power grip, please pay close attention to the list below (use my photos as reference);

- Add 10grams into the foam bumper
- add 10 grams on chassis by steering
- mount motor 5mm forward if you can
- what ever diff oil you use in a belt car, add 3-4k
- using a softer rear spring brings a closer suspension balance resulting in a slighter harder rear pressure compared to the front spring, this created more entry, mid and on power corner speed compared to using say an XRAY 2.7 which is way too hard.
- Use vertical rear body posts to eliminate any rear swinging weight
- I used the Xsquare suspension mounts only to quickly be able to change link lengths, the kit suspension mounts will be going back on, they are also the exact same dimensions as Xsquare

The shaft drive car is incredible, but the rear diff assembly is 51g, so all the things you see above is to bring balance to the front of the car which now stops any rear issues through out the corner.
Kit weight bias is close to 52/48 purely based on the rear diff and motor, that weight is not close to the middle of the car, by making these changes you will end up with a perfect 50/50 split even with a body shell on
