All of them?

I'm probably the wrong person to ask, my 210 has so much Tresrey its basically completely red (hubs now ordered to complete the package...)

I will break it down though:
Shim set - Actually yes. The stock plastic shims are a bit flexy.
Bulkhead - if you want a little extra weight, but not a lot perhaps.
Shock collars, thumbscrews, buttons - Bling really
Motor mount - Its better than the stock one (more secure, runs cooler, more clearance on the shock tower) but not worth it unless you really want red
Front rear wishbone mount - Worthwhile as much stronger than stock.
Rear rear wishbone mount - Worthwhile if you want to change angles, no point otherwise.
Rear camber plate - Yes. Stronger, better position and more options.
