i carry quite abit of stuff now that i think about it, not just an RAA card haha
-Jump Starter Pack
-Jumper Leads
-Torch
-Small Socket Set
-2 Screw drivers (1 phillips 1 flat)
-Multimetre
-Various duct tapoe and electrical tape.
-Zip Ties
-Dirty Towel and rags
-Cheapo trolley jack (the pole rides up front 4 hitting people)
-Wheel Brace
Last and Most importantly SPARE WATER OR COOLANT
Thats is all.......i originally put all that shit in my boot so id be prepared for a trackday but ended up leaving it all in there as its come in handy. Realistically id use the RAA card before most things cos fuck getting grease on my work clothes
thankfully i've used my emergency boot tools to help out other peoples cars so far and never my own (touch wood)
