Having no idea of Scott's experience level or driving style, I want to offer
one different view:
It ain't all about the equipment you have on the car.
Perhaps you can slow down to go faster.
I had an epiphany of sorts at the 2000 Solo II Nationals, after seeing some
photos of myself in a key corner that were taken by the trackside photog
there. He caught me in the same place on two different runs. On one (first
run) I had major rear wheel lift. On the other (third run) I did not. And I
was 1.6 seconds quicker on the third run.
The car is a Mk. I Spitfire, D Prepared in Solo, G Prod in road racing. And
yeah, it has a welded-up rear so wheelspin is not really my problem.
The difference? On the third run I backed off sooner for the entry to the
corner, got on the gas sooner and was accelerating through and out of the
turn.
When I came hard into the corner and was still braking heavy as I turned in,
I got that inside rear wheel way up in the sky. Made for a really
spectacular photo, but I could also see the error in technique. Already into
the turn, I was still trying to get slowed down.
When I got my braking done earlier, when I was shot at that same spot in the
corner the car was flat, all four on the ground, and actually looking very
un-spectacular ... but demonstrably faster.
Not so easy to do. Man, you just KNOW you can go deeper into that corner.
Yeah, you can, but then it takes longer to get back out of it again, and
that is the key.
I'd attach the photos, but Mark's program would just strip them. [That's not
a complaint; it strips all kinds of bad stuff too! :-) ]
