Gavin-
I can't confirm that the rack is the same or different, but I can say
that I changed my steering ratio by changing to Spitfire/GT6 steering
arms. They're shorter, creating the closer ratio. Only trouble is, you
need a torch to heat them and bend them straight to clear the brake
disk. I'd guess it's probably cheaper and gives the same result as
buying another rack.
BTW, I checked with my local racecar builder/expert, who told me he's
seen lotsa these done without subsequent heat treat, and none have ever
snapped. Don't heat them cherry red, just enuf to bend them in a vise.
