Hi all. I have a 90 miata with a vvt swap (i/h/e and standalone) and 6 speed. It is basically a track only car and at the moment it has a 4.1 diff but I also have a 3.9 just sitting here. It kinda feels a bit busy but I have next to zero track experience so I dont know how my opinion will change over time. What rear end would you put in?

i plan to stay na until im faster than the car which wont be for a while. the car is setup for forced induction though (forged internals, injectors, oil cooler etc) so its always a little tempting. ill keep the 4.1 in. i think the issue is that i havent had more than one track day at any particular track yet so getting a feel for the new tracks and the new car is a little bit much to be taking in at this point.

Work on your driving, but keep the 3.9, you'll want it once you go forced induction. Throw it in if you want, but it's a waste of time currently.
You'll just end up using 3-4-5 instead of 4-5-6. Shifting isn't the place to shave lots of time. Especially once you start running more power.

good to know. im not too worried about dropping lap times. i just got the feeling from my track days that i was kind of between gears for a lot of the corners and its hard to focus on other things when that happens. i guess that just means i need to go faster and avoid the lower of the gears all together.

I second sticking with the 4.1 also.
