One of our local drivers was driving a cyclone S pretty much stock in mod. Speak to Alonso about it (you know the chap ;P).
But basically the things you should upgrade are:
Since spool would be best in the front upgrade the centre pulley system otherwise the plastic centre pulley to the front will strip.
Upgrade the dogbones to 44mm HD Steel universals. You will also need to get wheel axle stubs and universal rebuild kits.
Maybe upgrade the ball diff to proper diff cups, the plastic on the stock ones is pretty ordinary.
And give the c hubs to an xray driver and if they fit tell them they are great bling!!!! (the stock cyclone S Chubs are made of some really brittle plastic, throw them away and get proper carbon graphite ones).
After that you are looking for bling factor and lightening the car.
I would got for CF main deck next, that lightens the car significantly. If you replace the main deck and not the top deck i found you need a couple of shims for the top deck (dont remember what i put in there i think 1.5mm)
From what i can tell:
Don't change the pivot blocks unless you get a carbon fibre main chassis. I did it and the chassis snapped at the rear on its first run. I think that the tight fit of the pivot block and the fact thats it is metal transmits a lot of stress through to the frame. Also the stock plastic pivot blocks have shims built in already so that the roll centre is already raised. Havent worked out if the add any kickup or anti squat or not.
You dont need to add ackerman to the steering it already has ackerman built into it (i think its 4mm)
Thats all that comes to mind, he should do just fine
