There were various ratios available from the competition dept., 4.10
(available as an optional ratio on the TR4's from the dealer) and then
4.33, 4.55 and 4.88 (actually 4.875).

Just for the record, I run 3.70 on my street car and currently run 4.88 in
the race car. The race car is going to get the 4.33 set over the winter.
And I'd better get "crackin'", there's about nine weeks to the first event
in 2003. YIKES!

I have thought about 4.10's for the street car (and an O/D) but the race
car uses up most of my Triumph $$$. The race car also uses up some of my
mortgage money and some of my food money. If I still drank beer, it would
use some of that too. =:-0
