Installed MTI shifter
Installed my MTI 6 shooter a few weeks ago. After a brief break in period, it is exactly what I was hoping it would be. Good positive shift feel, short throws and not much more effort than stock.
Unfortunately it has a slight rattle at full throttle, above 3k rpm. I've narrowed it down to the little plastic cap, which needed to be removed from the stock shifter and placed on this one. So there's nothing wrong with MTI's product.
So why didnt it rattle before? The only thing I can think of, is that the new shifter doesnt sit as low as the stock one in the transmission tunnel. I took it all apart and held the plastic cap in the transmission tunnel with a pair of needle nose pliers. The lower it went, the less play there was. Unfortunately a very small change in height really affected the level of play. Anybody have any ideas?
Overall I'm very happy with it and I can barely hear the rattle with the radio on.

I installed an MTI Racing Six-Shooter in my 2000 FRC. No rattles....just a nice, firm, smooth shift. Also put a billiard ball style shift **** on it. What a great combo. I enjoy them both !

Do you have to change the boot?
Does it come with a ball?
ps. I did receive it yesterday, and the build quality looks excellent. It'll be a couple of weeks 'til I install it, because it's coinciding with sound-deadening, but I can't wait.

Maybe the plastic cap is worn somewhat and its diameter has shrunk? Just spitballing here. Seems like the plastic would deteriorate after so many shifts in its lifetime. Is it a replaceable part?

I followed the MTI instructions to the letter. I didnt add any spacers or washers. I guess it's possible that the plastic is slightly worn, but the car only has 12k miles. I'll have to check with the stealership to see if I can order just that part. It would be worth the effort to see if that cures it.
I understand that there's no way to lower the ball any further. I was just brainstorming. Everything is manufactured to a certain tolerance and was wondering if I received a shifter that may be a little higher than the others. And I'm talking a very small amount, like an eighth of an inch.
Actually I just thought of something. Do you think the orientation of the plastic cap matters? In other words, is the cap round or slightly oval?

I thought the cap is round. There's no way to secure the cap on the ball, so having it be oval wouldn't serve a purpose.
Did you get an aftermarket shift ****? It may be entirely possible that the rattle and play in the plastic has always been there, but either bushings, grommets or whatever incorporated in the stock shifter and shift **** served to stifle the vibrations.

I drove the car without the shift **** and the rattle was there. I'll try replacing the plastic cap and see if that does anything.
Other than that I'll just deal with it. There's too many things I like about this car to have this bug me.
Thanks for your ideas.

But, I am planning to re-install the shifter. The only thing I can think of is that when I took out the stock shifter, the original gasket had pretty much disintegrated, and maybe my scraping it off with a flat-head screwdriver wasn't sufficient. I should take a razorblade and some sandpaper to really get it smooth.
Also, the gasket that GM provided was rubber or plastic and the MTI is...not. I don't know what it is, but it looks thicker than what GM provided and probably didn't compact as much. I think the ball is sitting too high in the socket, giving it a miniscule amount of play. If I remove the MTI gasket (as well scraping/sanding the GM residue), the ball should sit down nicely.
Maybe this should inspire a footnote on MTI's instructions.
(For what it's worth, the rattle isn't loud. It's very minor, very fast, but it's there)

I think your probably correct about the source of the rattle being a slightly loose fit of the black plastic cap at the bottom of the shifter shaft. I've had a shortened stock shifter (no rattle at all), followed by a modified B&M 45044 shifter (rattled loudly and all the time), followed by a shortened C6 shifter (rattles lightly but only occasionally).
I was surprised that a stock shifter would rattle, as I've only heard of rattling with aftermarket shifters. Mine only does it every couple of weeks, or so, and it rattles only for a short time (maybe 50 shifts, more or less). I think the plastic cap must slowly rotate as the car is shifted, causing the rattle only at a certain positions.
I have a solid shift ****, so that's not the source. If I had an extra plastic cap, I would try to score the outer circumference with a sharp knife all the way around to slightly raise some material, increasing the size slightly. If you find a fix, please pass it on.

My MTI that I installed two weeks ago also has the same rattle. From 2000 RPM up it "Buzzes". If I hold my hand on it, there is no noise. By the way I did use silicone grease on the plastic piece. You never notice it around town, only on trips so far.

And here I was beginning to think I was the only one.
The rattle is still there, but like I said before, it is very minor. Plus, I just had the headers and mufflers installed (see perf results forum for details), so I dont even pay attention to the rattle anymore. If I drove by a cemetery, I think I could wake the dead.
Eventually I'm going to order a new plastic cap and see if that does the trick.
