thanks jub jub... i think i might give this mod a try. i tried using dynamat, and that stuff almost totally eliminates the noise... UNTIL it rips. it's not made for moving parts.

anyway, i am worried about removing those stop bolts. so, there are not problems at all with removing them, when using the hurst on a z06 transmission? why were they even there in the first place then?

thanks.
The stop bolts are for speed shifting-drag racing-so that you don't break the shift forks. I installed my Hurst with no bolts,no springs,and the stock knob,and I have no problems with noise or vibration. Then I did the anti-venom mod with a 1.5 mm washer to reduce shift effort. Most guys seem to use about twice that-around .1"-it's a matter of personal taste.

i have a b&m ripper and no sound proof material and notice no noise, but shifting can be troublesome from 2nd to 3rd, sometimes 5th. is this the b&m or just common c5 shifting. i modded the shifter to be lower and changed the angle, seems to be better. what do you guys prefer for c5 z06 shifters?

You invert the plug and stick it in the boot. It doesn't have any affect on the shifting. The plug is only a few bucks so if you don't like it, you're not out of a lot of money.
Are you talking specifically around the shifter about 6 inches down, where the hole is?

Maybe my boot isnt inverted. The car had the shifter on it when i got her.

The Hurst shifter was much too noisy for my taste. Part of the problem was increased noise coming from the torque tube because of the big gaping hole left by the inverted rubber boot and a increase in rattling noise from shifter vibration.

The first thing you want to do is to remove the two shift stop screws. They aren't necessary unless you are going to be power shifting all the time. By removing them the shift shaft won't make contact with the stop bolts so you won't have to worry about that particular noise.

Next, go to your local hardware store and purchase a 1-1/2 " PVC rubber plug.

Take an Exacto knife and cut a hole in the center just slightly smaller than the shaft, apprx 5/8". Do a better job than I did though.

Place upside down over shaft and down into the stock shifter boot that has been turned inside out per Hurst instructions. Note: One 2003 and later models there is a hard plastic ring inside the boot that will have to be removed. You can cut it out with diaganol wire cutters.

I didn't do this but thought about it afterward. You could take some high density foam and stuff inside the opening for more sound deadening. It is very quiet without it though.

The finished product. No bulging and looks very stock.

This mod eliminates the transmission noise that travels up through the tunnel and eliminates most of the rattling expereinced by engine vibration. All in all, a very worth while mod and it's cheap!

What does the plug look like? I don't see any pics
