I wanna ride Mike
Just as long as @Sandshark is not the dick on the end of the rope who pulls too much and rolls your newly built car over for you. LolIf you don't carry a jack, carry a tow strap. Throw it over the roof and tie it to the roll cage. Hook the other end to your buddies car and he can lift both wheels on 1 side off the ground for an easy tire change. Technique is almost faster than using a jack.
I carry epoxy stick, you would be surprised of what it can fix!
