Apparently Topspeed types fit low drag tyres for top speed runs. If you folded down the Stag's seats and fitted Micra wheels you'd be onto a winner for your cliff run.Thats so very true slip is important - I missed gear cos my hand slipped off the gearlever when I tried to change up.
Of course I wont have that problem if I use the LC going down
Apparently weight saving makes you faster too so maybe borrowing some cylinders of hydrogen to stick in the boot would add a couple of MPH. With the seats down you'd be able to get loads of cylinders in there and double the effect.
