What do you think of this custom shift ****? Feeler?
I recently took posession of a beautiful CNC Machined Stainless Steel short shift ****. A good friend of mine, Clint, from So Cal, is an engineer, and developed a CNC program to cut these *****.
I have showed this shift **** to several people at ZDAYZ, and most everyone that has seen it really likes the look and feel. It's a very different and unique shape, vs. the other ***** on the market. And unlike the aluminum ***** that get VERY hot in the sun, this one stays very lukewarm to the touch.
Take a look...any comments? I am sure Clint will chime in with his commentary on how he developed this ****. If there is enough interest, my company is thinking of ordering a special production run of these shifters.
Any thoughts or suggestions are welcome.

Looks nice! Reminds me a lot of the Nismo GT ***** except this one has a lower piece to it. So you're saying this SS **** stays cool? I'm a bit skeptical on this one unless this material is mixed with something else like Titanium which does stay fairly cool. SS/Aluminum under direct sun light is like grabbing an iron & ice cold during winters.

Stainless steel remains MUCH cooler than aluminum. I hear you on the AL heat issue....thats why I never bought one. Even on a cool day, the sun shines in the **** soaks up a lot of heat....I could barely put my hand on it for a second. If you get a chance, feel a Kinetics sheetmetal SS plenum after the engine has been running...they are relatively cool to the touch. If that was AL...you could fry an egg on it.
The SS **** stays much cooler. I havent tested it on a 100 degree day, but so far, its been about 90 degrees in Charlotte, and it has been cool enough to grab and go...without burning your hand.
Mia, the cost will be roughly $100 shipped.

I actually really like the look and feel of the stock ****, but just wish it wasn't so tall. I know that sorta thing would be much more difficult to design and manufacturer though.
What I don't like about a lot of the shift ***** like the nismo is how thin they are. They feel like they poke the palm of your hand rather than rest in it and feel comfortable

i haven't a clue about machining, sharif -- can titanium be machined by the same tools in the CNC machine that SS can?
if so, any way I could get a Ti version? (i can probably supply the blank) I just love Ti quite a bit (stays cool, very lightweight, very strong, etc...)
thanks

This was originally intended for personal use, as I failed to locate an aftermarket **** that suited my personal tastes and needs; something that was esthetically pleasing, significantly shorter than stock, firm feel and provides excellent grip (no slips during my road races).
It is solid billet CNC construction out of 303 stainless steel, polished ... highly corrosive and scratch resistant with excellent thermal property (8-10 times better than aluminum). It is shorten quite a bit (from OEM length) for improved appearance and to gives the sensation of a more precise and shorten throw. The shape was designed to be non intrusive to the face of the palm that also facilitates a good grasp while discouraging slipping.
I made two for the heck of it and one of em found its way inside Sharif’s immaculate Z. It's looking good there Sharif! I think it compliments your interior well. Your shifter boot looks kind of out of control there though buddy. Tuck some in son!
303 stainless-steel was chosen for its mass, durability and heat properties. Titanium was originally considered, but proved to be more troublesome to deal with (for my machinest). It's only advantage being better thermal properties. Even then, thermal conductivity of different alloys of titanium vary wilder across the chart. I did liken the fact stainless steel was twice the density of titanium. The secret to a solid and direct shifter is mass. I had an early prototype made out of 6063 aluminum alloy. It looked really sharp, but it just didn't feel right (too light). Every shift felt very cheap and hollow ... much like the oem ****. We won't even get into how ridiculously hot that sucker would get just under the sun of a mild 85-deg. day; easily causing 3rd-degree burns if one were not wary. Into the trash that one went! Under nearly all circumstances ... the SS **** will be warm to the touch. Only under the most extreme condition will it get extremely hot.
Here's a chart showing two physical properties of the metals:
Material ............ Density [g/cm3] ... Thermal Conductivity [W/m-K]
------------------------------------------------------------------
Al alloy (6063) ......... 2.71 ............ 180
Al alloy (2011) ......... 2.82 ............ 138
Ti (alloy) .............. 4.5 - 5.0 ....... 4.8 - 16.3
Stainless Steel (303) ... 8.03 ............ 16.3
I'm glad some of yall like the design. Here are more pics:

Looks great
I would not mind having one in my Z
100$ shipped sounds about right, but if you get a large interest going, hopefully the price could drop a little.
How much does it weight over stock ****? I don't mind something with a more "solid" feel

Overall I like the way it looks. I think maybe going a little bit bigger on the diameter might be good to help it feel better in your hand. Like sentry65 is saying the smaller diameter ***** tend to dig into your hand a bit.
BTW if you can't weigh the ****, could you get a measuring cup and check it's displacement? So long as the displacement measurement is accurate you can figure out the weight.
I'm interested in this critter.

I've actually seen it and shifted with this ****.
As soon as i gunned it thru the different gears, i knew i had to have one.
For me, non-slipping is VERY important also.
Not for my road races but my highway rushes j/k
In the past, i've used the following ***** in chronological order:
Stock => NISMO Ti GT => UTR Titanium (blue tip) => THX SS **** (hopefully soon)
I'm rocking the UTR one presently. I prefer the UTR over NISMO GT because it slips less. The GT **** felt better in my hand but had a tendency to slip once in a while (mornings or dry hands) The UTR slips less because it seems to be less "porous" and your hand seems to attach to it better.
With this SS ****, it's pure grippage. Your hand doesn't have to BALL up to grab the shifter.
Instead, it's a true "pistol grip". However, still allows you to grip it from the top like a ball.
Can't wait til i get my own.
