stl gear ratios rule interpretation Q

[tom91ita]

Doesn't the GCR define "gearset"?

if not, then mix n match should be okay.

what combo of gears are you looking at?

"gear sets " is how its actually written...2 words

I'm currently looking at ZC 3-4-5, the 4.7 I have, one of the quaifes I have... I'm getting the engine running first, then I'll drop the trans and play with it over the winter

When we wrote "gear sets" I believe we intended that to mean gear pairs, meaning you can mix-and-match gear ratios within the box.

Write a letter to be sure.

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.

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.
