Good point on rim width Dale!
We used a bicycle speedo(sigma)on Deb's 250 sprint last meet with a very
small difference at 82mph to the time clocks on a very quick initial setup
(should have it dialed in exactly with ecta clocks next meet, which will help
with testing at the shop). I like your idea of running one on the rear and
one on the front to show difference and know it's not clutch slippage which
the tach can't differentiate.
Of course with her sprint, the only tire slippage she's going to get on the
concrete is if there's alot of oil on the track...haha.
