I've got 3 RA-1s on order with Toyos Only for delivery at Nationals but I don't really need them right now. I used a new set at Thunderhill for comparison and I'm not sure they were any faster than my ~ 25 heat cycle set.
Sounds like if we put our heads together we could come up with two full sets of RA-1s. I had $425 Toyo bucks and the tires were $157 so I was out of pocket a bit to get 3.
I always carry lots of spares. I've got a transmission, trailing arms, control arms, rotors, calipers, brake lines, shocks & springs, axles, radiator, computers, electronics, and lots of fasteners. And of course, beer
Who needs alternators and starters, those just add weight
