Are there beefier guibos that can be put in place of the standard M3 guibo. (Like the guibo from the E34 M5)

E46 M3 Guibo fits.

I duno I just checked mine this weekend when i was checking my Gear Oil. and it had strings poping out :nono I guess that what 14 psi and a 100 shot not to mention my ACT 6 puck. But would it be possible to machine a buillit disk and just give it no flex, or would that make it nearly impossible to drive, given there is no flex in the driveline anymore???

Machine a billet disk, and have a great time blowing your transmission to pieces....

So that would place way too much stress on the tranny? haha i guess it would.....

Is the E46 M3 guibo thicker than the E34 M5 guibo?

I think I read somewhere that the E34 M5 guibo would fit the E36 vehicles.

The guibo is designed to absorb shock from launching and whatnot...without having it there to absorb that shock...where is that shock going to go? Your tranny is going to bite the bullet from that....

did you notice any ill effects from that torn up thing?

im suprised you didnt feel the dribveshaft stumble. When mine ripped my shaft was stumbling. I drove it like that for a bit and the shaft bearing blew out.

You will, more than likely you will feel a serious vibration in the drivetrain. I replaced mine a year ago and it looks like I already need another one. It is like a shock meant to take the drivetrain force and deaden it. But it wasn't meant to handle our kind of torque:)

Dude that isn't a bad guibo, at the shop I work at a stock e30 came in with almost every cord showing. But nice job at killing that guibo.

Exactly what mine looked at. And I had mine replaced right before I took it to for the install 2 years and 2k miles ago :D

Did I mention that was the upgraded E46 M3 Guibo/flex disc I had torn up...

The guibo's flex is more for the rear end and drive shaft than the tranny I think. I rarely hear of busted trannys but rear ends and driveshafts especially are prone to failure on 360 rwhp cars.

Think about where the guibo is placed...what's more likely to get affected?

My guibo looked nearly that bad when I replaced it last year. Checked it recently and it's holding up fine so far.

You'll notice a big difference in smoothness when driving if it is that worn once you replace it, and you'll be doing your tranny and diff a favor by replacing it as well.

So does anyone have a recommendation for a stronger replacement guibo for the E36 or is everyone just going with the stock guibo?
Jim M3

E46 M3 is stronger and a direct replacement.

Yours is still in good shape compared to mine. I hear someone makes a urethane version which is much more resistant to damage. The guy that had the urethane guibo says NVH is not present. The guibo is probably a buffer against drivetrain stress. Since you turbo/SC guys are launching hard at races ANYWAYS, the guibo is probably not helping you.

Before everyone says you NEED rubber guibos, I think the usual arguement that BMW engineers know best and they can't be wrong is BS because:

1. RSM
2. Trunk Wiring
3. Money Shiftability
4. Nokia stock speakers
5. Clutch pedal squeak
6. Etc etc etc

I personally believe everything outside of the BMW ENGINE and FRAME is not sacrasanct to scrutiny.

When we turbo guys launch hard at the strip...well at least me...would rather have an item that costs a tenth of what a transmission causes. I have not heard good things about urethane guibos...I have heard of nuked trannies from installing either urethane or solid guibos...there was talk about this on a rival forum a while back. Personally, I'd rather have to worry about replacing the guibo every so often (which would be a while) and be able to launch without worrying about making a gear explode into tiny pieces...which I would have to worry about with a solid or urethane one...because that's the reality.

Also, don't expect urethane to last any longer than the rubber ones. Look at the properties of urethane. Yes, it's flexable...but under repeated forces, it will deform based on where the force is being applied, and will not return to its original shape, unlike rubber. Just something to think about. Bottom line...I'd say to put the E46 guibo in...if you want to play chicken with your tranny...by all means...go for a solid or even a urethane one...

I disagree. I believe whatever problems you claim above can occur with whatever material the guibo is made from.

I remember now, it wasn't urethane. It was an aluminum guibo. My point is, the guibo is not all that great of a shock absorber when you clutch drop the tranny. I have heard the exact opposite from you that the solid flex disks are great items and the people that use them have no problems with destroying their trannies or anything else.

If you don't want to damage your car, rubber guibo or not, stop launching your BMW. Every time you take you car to the track, you play chicken with your car's reliability. The flex disc will not be the savior of your car in any catastrophic event. Rubber, Solid, or Aluminum. With the aluminum one, you won't need to change it out at the regular interval of a rubber/nylon one.

Definitely, to each his own.

It may not be the savior...but every little bit counts...and I'll take that little bit...
