Default Help me pick trans ratios

I have three choices.

Here's #1 and #2: MFactory® Competition Products - Gear Calculator


#3: MFactory® Competition Products - Gear Calculator


Work necessary for each set:

#1) Take gear stack and put it on different final drive. Reinsert into original case.
#2) Remove entire guts from one transmission case, dump into another
#3) Remove guts from two transmissions, take 2nd gear from one trans, 1, 3, 4, and 5 and final drive from other. Insert whole mess into case from trans that donated 2nd gear.


Which one would you run and why? Car is making ALLOFIT power, is FWD, and traction is an issue.

Why is this post about your FWD-powered non-Miata in the Miata-specific section of this forum?

I agonized over where to place my business on the forum for a good 5 minutes before flipping a coin between this or "BS," and went with this under the guise that there was no automotive things in the BS section, and figured i'd rather **** up a section that deals with transmissions with my transmission question, instead of **** up a section about cats, police murders, and food with my transmission question.



Wherever it needs to be moved, i'm quite happy with, as long as i have the chance of getting insight from the smartest collection of internet nerds i know. (What's that **** smell i'm getting right under my nose?)

I would go with #1.

The taller your first few gears the better for a traction limited car. If your traction issues are only in first and second I would consider option #3. Amount of work required for #3 would make me lean towards #1 even if traction is OK in third.
