It seems that having several sets of different
circumference tires would be easier than changing
gears. By default, I ended up going that route
last year with the FWD car I had. I borrowed
wheels and tires from two different guys right at
the track, combined with the extra set I had with
me, I had four different sets of tires from 22"
tall "Goodyear sportscar slicks" on 13" BMW
wheels borrowed from Bruch, to 26.5" tall on
Chrysler 15" wheels, which were the oversize I
had brought to compare against my mounted 25.5"
tall 14 inchers.
I'm planning on doing the same thing with my
roadster: 1 set of tall front runners, one set of
2" shorter 15" speed rated street tires, and one
set of really short street rated tires. Using the
formula that Mayf has posted on his site, with
the 3.08 gears I'm using, I think these tires
should give me effective final drive ratios for
nearly anything my motor might put out.
Does this work out to a "poor man's quick change,
or am I missing something here?
