Tonys screws do a kit for the Durga - I'd highly recommend it. Most of those will use a 2mm hex driver - the cheap HUDY ones are the best I've used, the ones with the plastic handles.

Spares - the usual stuff is good to have, front and rear wishbones, hubs etc. I've broken a front and a rear on the durga - generally speaking the front is especially tough, and the rear in my experience is only slightly weaker. Sometimes the inner rear wishbone can break in a big roll - but I've only done about three myself in a couple of years racing.

I never broke a shock tower - but good to have as a backup.

Definitely get a 37t pulley as a spare - along with centre pulleys and a belt or two. I dont remember if I ever really had a break on the Durga but if you don't build things properly or something comes loose and you race without checking then it can go bad quickly.

Get some shims and shim out the front and particularly rear suspension to remove the slop on the inner hinge pins. If you do this it'll stop the hinge pins popping out in a big crash and losing some vital parts - killing your race day!
You don't need loads of fancy bits of metal on the car to make it strong - I never even had CVD's on my car and it was brilliant.
