    adam,

    look for a 4spd and use that 1-2 set with ZC 3-4-5 or ZC 3 Si 4 ZC 5. puts 2-5 in a good tight range. same setup works wonders in the FP hatch with a 4.7 and quaiffe, ~150 whp, huge drag.

    FP car use oem-height tires? Looking at gear calculators, yeah.....this is a great combo... thanks! As soon as I decided STL was what I wanted to try, I bought a 4speed, HF, and zc box . Haha

    My thought was the previous interpretation was "Gear set" = all of the gears in the case.
    i.e. you can stick a NB Miata gearset into a RX7 box. the whole gearset, not just 1 or 2 gears. However, that was a year or two ago and the phiolsophy may have changed now. Write the letter as Greg mentioned (and you did.)
    Please post response.

    3-5 is about all you need during he race but a good #2 for the green flag is necessary as well!

    I find myself increasingly uninterested in answers to questions like this...

    I also thought STL specifically only allowed complete box range swaps, AND that the difference between STU and STL language on the matter was the proof of that. Rules could have been merged, more and more I also have lost interest in the class, despite it being what I always wanted to see: limited prep rules allowing engine swaps in same make chassis.

    People are only getting these changes because they're asking for them...

    15in wheels, 23ish inch diameter rolling on slicks, 4.7. Maxes out 5th and still uses 2nd on tight corners. 13in wheels and smaller dial tires get nearly the same wheel speeds from a 4.25 final.
