Repeating some of the previous replies...
The alloy caster adjuster is the key upgrade for the F109. The stock plastic part can break in the thinner sections if you have a heavy shunt.
The CRC side spring mod doesn't use F109 upgrade parts, but is a big help with side to side movement. I've used Associated side springs but used the same basic approach. Details are covered earlier in this thread, and seen lots of references to how to do it.
I'd also recommend running 1/12th front springs rather than the F109 kit. And as the F109 centre shock is the same dimensions as a 1/10th Touring Car kit, then Touring car springs fit it fine. I've been running 14lbs and 16lbs springs on it.
I have a wide range of 64dp spur and pinion gears. To run that spur you'd need the white plastic F109 spur gear adapter.
I'm still running kit tyres. I have got the stronger side links but these reallt aren't essential in my view.
Hope that helps
