Didn't leak and doesn't come with a gasket. I actually made one just in case it helped with any nvh

Just realized you opted for the 3" version so that might explain some things. I put down a thin bead of rtv and never had issues.

If you were talking about the synchro jams at times my friend has the IRP shifter and he has the same thing happen when he shifts fast. It's just a typical thing with the short shifters since you can cover the gate distance a lot quicker

I had the shifetr for a day now and around 4k-7 the shifter does have a somewhat violent rattle/ vibration does your shifter do that?

Melvin

Yeah it does that with mine too

So its been a few months, are you still liking it? How bad is the vibration and rattle? I would think that the inclusion of the OEM lower bushing would have helped with that.

Melvin

I still love it. It still has a vibration above 4k which is definitely noticeable but I don't mind it too much considering the benefits. It hasn't gotten worse at all, and I think the OEM bushing is doing it's it' well

chr

I have the one without the bushing and the vibration is noticeable but I dont care at all has no slop either but I do wish I got the taller shifter

Reviving old thread. Is it more precise? I have the 99-00 6 speed and struggle with the 5-4 shift. Don’t feel like I need a short shifter but would like to increase shifting precision. Trying to decide between miataroadster angled and this GRacing.

Did you decide on either shifter? I'm in the same boat, this vs the miataroadster shifter.

Anyone else have any long term reliability updates?

I bought the GRacing one. Yes it feels better and yes it’s easier to find the gears with the 6-speed. But my god does it make a lot of noise. I can hear the buzz/rattle even with my helmet on, at speed. Not for a street car, IMO.

Was your cut down to allow the factory bushing? I'm wondering if that is the source of the sound.

it was not. I specifically asked about that before I ordered, and was told that it was not necessary and it wouldn’t help. So I followed the advice I was given and here we are. I can’t say if it would help, because I have not tried it. But I think anything would be better than what I have.

My car is primarily going to be street driven so the GRacing shifter may not work for me. I may just spring for the miataroadster shifter..

I'm curious where the vibration on this shifter comes from, if running the oem bushing like Melvin doesn't fix it I'd imagine it's vibrations from the trans and shifter body possibly causing the shifter ball and the body to cause the vibrations. Maybe open it up and add some grease in the shifter.

On my MR shifter all the buzzing comes from the plastic bushing they use to make the kit universal to both 6 speed ball sizes.

So there's the cup in the transmission, the bushing that goes in, and the ball on the shifter, they've got some play in them. Unless the bushing is press fit into the cup it's going to buzz against any slack it can find, and it will. The itty bitty teeny tiniest little bit of force onto the shifter will shut it up, maybe not even enough to load the selector forks...

I've been meaning to take mine out and cut a groove in the OD so it can take an o-ring, then press fit into the cup a lot better. I do not think the weight of the shifter and **** itself will be light enough for the buzzing to continue, either that or it shouldn't be audible. Could probably just deform the thing a bit, make it a press fit, but o-ring is more easily reversible...

On the stock shifter the ball bushing is molded press fit onto the shifter ball, not a drop in bit like the MR. It can't rattle, uses the weight of the shifter to stay put.
