Wevo shifter against factory short shift kit?

I currently have a factory short shift kit in the car.
I received a Wevo for Christmas, so it will going in pretty darn soon.
I can give a good comparison at that time of the differences I see.

Walter,

It's a simple 1 min job.

The reverse lock-out sits on top of the tower on the rhs. A small cap screw holds it in place. Simply remove the pin - AND don't loose the parts...

For road driving the lock out is OK. I found that on the track the lever catches the pin in 1 out of 3 VERY FAST down changes and that is of course no good. I believe that the brutal treatment is to slightly modify (angle) the lock out pin - but I have never nicked reverse with my Wevo.

When adjusting the fore and aft dimension, be sure to have the rubber shift tower cover pulled up. As has been suggested, sounds like when shifting into 5th the lockout cam didn't spring back toward neutral, in which case it doesn't do anything to prevent pulling back to reverse.

If there is anything good about it, the reverse grind is, all things considered, relatively benign. Not good, makes you feel stupid, etc. But long term it isn't going to shorten the life of the tranny or cause you to need to replace gears. It is not like you are actually partially engaging these two gears. It is not even like the grinding you can get with worn synchros in forward gears, or if you rush your shifts and "beat" the synchros. I drove from Denver to Santa Fe, drove around there (including an autocross), and drove back with a transmission improperly adjusted internally so that when not in 5th or reverse it was almost like a light knicking all the time (muffler was so loud I didn't hear as much as others at the autoX did). No real harm done.

For a lower buck alternative to the WEVO, try replacing the two bushings in your shift coupler with ones made without the oval center hole that Porsche favors. That gets rid of an amazing amount of slop at a cost of peanuts (especially after you have gained experience adjusting the coupling.

Then consider adding a Seine Systems Gateshift or similar aftermarket product to spring load your shifter to the 3/4 plane.

That's the setup I run on my street/track and track only 911s with the RS factory shifter, and it is great. And saved money for other improvements.

Anyone have an updated opinion on this?

My 82SC has what I believe to be a factory short shift kit. This is based on what multiple mechanics have told me. I have no other experience with 915/Porsche transmissions/shifters. Although my shifter works well enough, I'd prefer that it center itself and any improvement in precision would be great.

I have a '75. When I first got the car it had a factory short shift kit. I switched to a WEVO and was immediately impressed with the improvement. My application is racing.

I have about 17 years of experience with my car and the WEVO shifter.

I know the folks at WEVO and I was a relatively early adopter. Great product, great people.

Recommended.

Look up the Seine Gate shift kit. I put one one my factory short shift and really like it.

You should not be nicking reverse with the factory shifter. The factory shifter works well and if your struggle with it, you either need to work on your technique or your car needs adjustment/repair...or both. While you may prefer the feel of another shifter (and if so, buy one), you need to fix those two problems before masking them with another shifter.

It seems that a lot of folks replace the shift bushings and coupler bushings when they install their new shifter and then are in awe of how well it works...attributing all improvement to the aftermarket shifter. At least half their problem was probably the the bushings/adjuster.

nonetheless, the Wevo or Rennshift install is an improvement to the factory shifter, even with fresh bushings.
adding the PJS coupler makes it 100%
For my experience I cannot say otherwise.

I’m not having any issues with my factory short shift kit, I just want it to be as good as possible. Rennshift and Wevo both look like good options.

[Rodsrsr]

I've been running the factory short shift for years and it works just fine. I really don't see the need for improvement, especially at the price point of a Wevo.

Then put the Seine gate shift kit in it and call it a day. It's a cheap upgrade to the short shifter that gives you the same feel and crisp shifts as the Wevo for A LOT less money. I have driven both, I am not guessing here.

That actually looks like a great option. For $150 it seems like it would be hard to go wrong.

Disagree with the Wevo = Seine "same feel " comment above.
I use a Seine on my road car,79 SC (yes a great product/improvement to the stock shifter -with new bushings).Absolutly recommend it.
I use the Wevo on the 86 DE car.It really adds a level of precision to the 5 shift notches or planes ,so to speak,that you won't feel with the stock shifter with any modification(s). Is it (wevo)necessary to create a crisp accurate repeatable shift motion ? No,it isn't,but then a 3.0 L doesn't zing you the same way a 3.6L does.

My 84 shifted fine with the Porsche short shift kit and Seine shift gate. It definitely wasn’t the best shifting car, but it didn’t grind and all the synchro work as intended.

I just bought a Rennshifter and Wevo precision coupler last week. I installed the coupler first and it made a minor improvement. Admittedly my stock bushings were not worn (64k miles on the ODO) so I wasn’t expecting much from this change.

After that I installed the Rennshifter and it made the shifting feel dramatically better. I’d imagine the Wevo is similar but I’ve never tried it.

Who would have thought we could get two differing opinions on something?
From a function standpoint, the Wevo and Seine are spring loaded. The Wevo spring loads into the 3/4 plane. The Seine has spring pressure into the 1/2 plane which effectively does the same thing the Wevo does, if you pull out of 1/2 it automatically goes into the 3/4 plane. The biggest difference is there is less side to side movement in the shift arm because of the way the Wevo spring loads. I'd argue it's harder to accidentally go from 5 to 2 with a Seine than it is with a Wevo since the Seine has a lock on the shift arm that has to engage the tab that is installed on the top of the shifter housing where the Wevo is only spring loaded. There are no gates in a Wevo shifter.

$611 vs $150 if you want the shift arm to be rock solid, spend the extra $461. If you're okay with a slight bit of side to side play in the 3/4 plane, go with the Seine.
Not trying to get into a pissing match here as I'm sure there will be a lot of different opinions. I'm just pointing out that there is no big difference between the Wevo and the Seine in function or in the feel of the shift. The greatest difference is in how tight the shift arm is in the 3/4 plane. The Wevo uses a spring on either side of the shift arm that contact a tab on the bottom of the shift arm. When you are in the 1/2 plane you have spring pressure on the right side of shift arm. When you come out of the 1/2 and into the 3/4 you have even spring pressure on both sides of the shift arm which centers the shift arm in the 3/4 plane. Out of the 3/4 into 5/R you have spring pressure on the left side, but as I mentioned there are no gates like there are with the Seine system.

The biggest plus for a WEVO -apart from the function- compared to others is the clean and solid design!
as well as it's offering the classic rod or the billet rod, and further offering long or short knobs, as offering long or regular length rods.

very stealth under the oem boot, nothing sticking out, no drilling, just sweet... and this you only buy once in your life... costs are long forgotten, whereas the happyness for it stays forever.

edit: and what I personally love most is the quick install of those beautiful 917 knobs

cabmando,

Good "xsplaination".(old detroit boy term)

No technical argument from me.
