On my Acura I ran GM syncromesh FM. Very smooth shifting. Looking for similar shift feel on the m3. Not going to track the car, just spirited DD. I don't abuse my syncros, double clutch, and live in a temperate climate. What MT oil does everyone recommend on the m3 for smooth shifting...

I have a GX model (Canada), I think it's the SV-i in US, 2.0L manual transmission. That base model doesnt have a tachometer, so I shift by the engine sound.. It works well but it constantly bugs me not to know at what RPM Im shifting during spirited driving / acceleration.. Can somebody tell me...

I'm going to be changing my gear oil and am curious why it seems if someone is using Redline why they are using MT90 (75W-90) over Redline's recommendation to use MTL (70W-80) which would have a closer viscosity to Mazda's spec of 75W-80. Thanks for your input!

FS: CA - 2010+ Redline Goods armrest cover FOG LIGHTS SOLD Up for grabs is a Redline Goods perforated leather armrest cover. It's got a double stitch of light grey and blue to somewhat match the dash of the skyactivs. It fits really well. Just put it over the armrest like a sock and wrap it...

any of yall using with RedLine or amsoil right now? I'm planning to do a drain and fill. is it ok if i mix it with the OEM fluid?

if this is in the wrong place let me know - but just wanted to throw out a quick question to preface - im retarded... driving home on the highway today, little tired a bit hungover... was NOT paying attention, and went to pass, was going to put it into fourth (was going maybe 65mph?)...

So i noticed that the 2.5 redlines sooner than the 2.0, why is this?

Got the redline hood kit today and installed it. had to deal with one stripped bolt from factory, otherwise easy install. A couple of pics. Pat.

Just got finished installing them. Well written instructions. They work and look great! nice smooth 2 stage action. And no more prop rod. The hood lifts slightly higher than w/ stock proprod Over all I'm very pleased... Just a few notes 1. Buy a GOOD rivet gun!!! My cheap-o rivet gun did not...

The title pretty much explains it. I was tired of looking at that cheap e-brake plastic, and Redline recommended changing them both to be sure that they matched. Is there anything that I need to know about the install, or is it straight forward? This will be my first mod on the car! Humble...
