Use the Motorcraft fluid in the 6 speed.

If you don't know the life of any of your hubs, I would change all four this winter. Or at least the rears, and repack the fronts.

You can overlay afterwards with race render.

Motorcraft didn't work for me. It burned up.

I'm going to try a combination of Redline MTL and Redline Shockproof Ultralight. I've had great results with the Shockproof in the 5 speed with drag reduction and easing shifting by reducing synchro buzzing going into 3rd.

Yep, I know the transmissions are very different but I heard what Aidan had said about Motorcraft not holding up to the heat.

I know the Shockproof has worked well in other applications and I am willing to give it a whirl. I'll report if it works or sucks.

Overlay what? What program records the data? Can my Race Chrono or do I need a different one?

Good idea. Try things out. As long as you pay attention to it, maybe drain a little bit after a track day.

You have good heat shielding. I think you should be fine.

Richard, how long did you run Motorcraft on the track?

Race Chrono works fine. Its a little tricky your first time but I can write up a little how to with some videos next week.

This was made with RaceChrono, RaceRender, and my GoPro

Lol

I've run the Motorcraft since 2007 I think? It's always been in my car. I could dig up my m.net posts if I was motivated and not on my phone. You burning it up is the first I have ever heard of that happening. It's a full synthetic lifetime fill for street applications. I changed it yearly with about 8 track days/year average.

It's always worked for me. YMMV.

Understandable. I'm not hating on it. Just saying it didn't work for me. It also didn't help my shifting issues.

As Mobius said YMMV.

I never sent a sample off to blackstone for analysis. Next vehicle I'll do that when I change fluid after a season.

Your instantaneous response time concerns me. I think you've been borged.

What are you guys doing to my thread? Aidan's off topic ramble thread is over there somewhere>

lol

Pilot bearing had a little bump in it when I turned it by hand so it has been replaced. Throw out bearing is good and has low miles so will be reused. Rear main is newish and not leaking. Diff oil drained and it looked pretty green/dark. More heat shielding for diff will need to be arranged. Same with fuel tank.

I think it was just off the shelf Castrol from the auto parts store. I don't recall, but I think it was the heavier stuff 90wXXX whatever and not the lighter 80w90 judging by the consistency of what came out. It has been 3 years (I don't drive it much) and I just don't recall.

Exhaust was thinly veiled with heat fabric against the diff. There isn't much space, but there will be an additional layer this time. I am set up to make more power now and will be shielding everything more. At 6-8psi it was adequate. Not so much now.

Valvoline or Mobil1 synthetic for the diff would be my recommendation. I use the M1 but the Valvoline can be easier to find.

Another vote for Motorcraft. I was about ready to give up on my 6 speed (notchy/grinding) before I replaced the Amsoil I was running and it shifts 1000x better now.

Do those have any noticeable affect on the car's aero? My car feels very unstable at higher speeds, especially on breaking/decel. It's considerably worse than other miata's I've had even after an alignment. I've been wondering if a lip and/or spoiler would help at all.
