I think it depends on what you want. I thought Sav mentioned in a thread that the fastest car at one of the tracks he races has a 6 speed with 4:10 gear.
I ran all year with a 6s/4.10 combo, I know VagaXT still has his 4.10s in his MSM, and I believe TrackDayHokey kept his 4.10s when he switched to his 6-speed as well. So that would be the top 3 cars this year in MC Unlimited on 6-speed/4.10 combos.
Emilio ran a 6-speed and a 4.30 all year with his NA setup, I think he's going to a 6-speed with 3.9s next year. bellwilliam ran a 5-speed and 4.30s all year, just switched recently to a 6-speed and 3.9s. For big power, 250+whp, I think the 3.909s are the ticket. 3.63s aren't necessary unless you are looking for 350++whp - when I have an OS Giken built it will be using my 3.909 setup.
