Just thought I'd put a key pointers that I have on my set-up that may help you that you can research
- Maplin washers to replace the blue ones.
- Move Yellow spring out one hole on the back, change front to Blue springs.
- MI5 front end mod
- 30 degrees timing on motor, gear car to suit
- Ascari/Ferrari Bodyshell
- Rebuild diff as per the guide on the GT12 section of Facebook.
- Reduce droop? Haven't done this on mine yet but have been meaning to!
But to me, MOST importanly - weight balance!
- Target 950g overall weight
- 60% Rear, 40% front weight bias, or as close to as possible!
- 5mm washer to space off motor to try and recentre weight
- Add 30g-ish to non-drive side of pod to balance weight
- Add/move any other weight to try and get the car balanced left to right - makes the car LOADS more predictable.
Hope that helps
