The group wisdom was to leave the 4.55 in place; but I find that there is a
4.31 available from England and am pondering that....

Subject: Re: [Fot] Rear End Ratios
Finally catching up on old e-mails. This may not be totally relevant to the
TR3, but I'll toss it out for the group. We normally run a 4.11 in our
Spitfire and it works great at Portland without the chicane and at Seattle,
both long straights. When we went to the runoffs in 2010, I put together a
3.89 thinking I may over rev on the long straights at RA. Bottom line is we
couldn't pull that high of a ratio and went back to the 4.11, which worked
great.
