Wevo or Rebel Racing Mounts

[jcc911]

Is there any difference between the two products?

If one if looking to improve shifting, should the tranny or engine mounts be replaced first?

To improve shifting, first inspect yout shift linkage as it may be worn. There are some bushes in the std Knuckle/Shift Joint that can be replaced.

Adjustment of the shift linkage will also improve shifting.

WEVO make some great products, I would advise to do the above before you look at engine mounts.

If you want to explore improvement do it in the following order.

1) Adjust the std linkage and replace bushes

2) Replace standard shift joint with WEVO PSJ

3) Replace standard shifter with WEVO Classic or similar shifter.

4) Replace engine and gearbox mounts with WEVO SS mounts

Bearing in mind the 915 Box needs the driver to adjust their driving style. It is also possible that the gearbox needs to be refreshed as the above products will not improve a failing gearbox.

I have done the whole WEVO thing above and shift improved the most with the PSJ and then more with a WEVO shifter. Engine Mounts was a slight improvement.

Different types of Oil can improve the 'feel' as well, but thats a personal choice.

Buy the WEVOs and support the engineering that went into developing the mounts. The other brand is just a knock-off.

I wouldn't call the RR parts a knock-off. They were not meant to be exact copies, although they are similar. It is a case of convergent engineering, much like how the diamond configuration was the dominant bike frame design for many, many years. It is still the most efficient frame design and is only deviated from for recumbants and mountainbikes with certain rear suspensions. The polyurethane part is made to Clint's specification (durometer), for example and he told me the other differences but I do not recall them at this time.

Wevo have the different coloured pads... Blue standard sports hard, black more compliance for the girls

I love my Wevos.

[gtc]

Come on Max... aside from the finish they're indistinguishable. You're a sharp engineer, so I know that deep down, beneath all the shilling you do for Rebel, you recognize this.

[Flieger]

I've never actually seen the Wevo ones up close so I can't go from personal experience. I do believe Clint's claims about the polyurethane, which is the most important part of the mount as far as what the driver and chassis feels. Apart from that there isn't going to be much room for making things different within the stock geometry unless you want an engine mount with tailfins or something.

Yeah. Not exactly rocket science.
The colour of the anodising will determine sales.

I have two Wevo and two Porsche sport mounts. I did get some improvement.

]Interesting discussion, didnt realize the history on these.
So essentially they are the same. Now that I think about it, after I turboed my engine and reinstalled, I dont think I set the coupler properly with the "preload."

I did have swepco and new bushings put in about 12K mi ago.

I may have to pull out my Bentley and readjust. The custom 964 center console makes this a PIA, but it needs to be done.

I still think I will buy a set of mounts though as it wouldnt hurt.

Rebel racing is my vote

I totally agree. My 915 shifted poorly, I did numbers 1-4 above and was surprised at the difference. I then replaced my aging Swepco with Kendall gearbox oil and was further surprised at the improvement. Not perfect, but much improved, as in I could get every gear I tried for when on the trot. I just attributed the balkyness to the syncros in the 915.

I then watched Magnus Walker's video of him driving the 277 car, and his shifts were so much faster, effortless, and perfect and knew something else had to be wrong.

So I took it to a buddy who rebuilds Porsche gearboxes for a living. He took mine apart and found that the two main bearing bores in each case were egg shaped and there were signs that the races were turning in the bores. So they went to WEVO to be modified/strengthened.

So to make a long story short, the WEVO products are superb. They took an ailing gearbox and masked its problems. I can't imagine how this car is going to shift when the bores are aligned properly combined with the above WEVO products.

I'm running REBEL mounts in my G50 car, my brother is running WEVO mounts in his 915 car. We both feel we have superior products and again we are only talking motor mounts.

[Flieger]

I don't think I would be able to tell the difference between the two types of motor mounts. I am just not that sensitive to that sort of thing. I might be able to tell the difference from stock to aftermarket. Probably not since my car is pretty racy already.

I agree that you should inspect the bushings, coupler adjustment, etc. before going with new engine mounts. You should be able to shift fine with factory mounts.

I'll be buying rebel eng/trans mounts, the gold anodized wevos are to flashy for me.

[Halm]

Unless you are going to the track, get a set of Sport OEM type mounts. You'll get close to the same results and save yourself the NVH headaches.

[911dean]

I replaced my club sport engine mounts with black Wevos. I like them alot, so much that after typing this I'm ordering some for the trans.

I do admit that I like Rebel Racing's products also.

I just had John Walker here in Seattle go thru the 915 trans in my SC and wow does it shift nicely. It was fine before, no grinding, but just a little sloppier than I liked. I ordered the WEVO bearing retainer / intermediate plate reinforcement which is a very impressive part - it looks like a jet engine part. In addition I installed a WEVO coupler and mounts on the transmission crossmember (engine mounts are OEM "sport" mounts from our sponsor.

I'm very impressed with the results, it shifts like a swiss watch now.

I am not a huge fan of gate shifters on these cars. Opinions vary, but the torsional deflection caused by cornering loads can throw the (gated) shifter out of alignment with the trans, resulting in hard shifts or no engagment. Maybe on a race car with a roll cage (which would reduce body flex), but for a street car, a properly adjusted linkage and tight coupler (even the OEM one) should be sufficient.

you should think about your post, Kevin
