Whats the Most Durable Guibo for Track Use?

[Nsquared97]

Really, though, I don't know why I'm bothering to respond to a typical stamar post. We have determined that E30 guibos are undersized on the basis of one that was probably an incorrectly installed Chinese knockoff, even though the replacement has been working fine for years. Oh yes, and furious googling.

This.

Comparing the photo in the original post to the photo below from a Pelican Parts Tech article, it appears that the guibo is installed in the same orientation, no?

The only difference I can see, other than the buggered guibo, is the orientation of the bolts.

For proper installation the bolts should run through in the direction of the arrows moulded into the sides of the rubber guibo. The red arrow in the photo points at the triangular arrowhead stamped into the rubber.

First bolt the guibo to the driveshaft flange. Then bolt the driveshaft with guibo already attached up to the transmission flange.



This way the guibo will sit, as shown, in the proper orientation with the thicker portions taking the load under acceleration.

There are metal sleeves bonded into the rubber of the guibo through which the bolts sit. Those, obviously, prevent the rubber from squishing as the bolts are tightened.

Here's where I suspect the problem is. You must hold the bolt head from turning while tightening only the nut. That way you won't twist the metal sleeve in the rubber, possibly tearing it from the rubber.

Another reason the proper bolt direction is important is that, with long exposure to salty climates, the bolts will eventually seize solid into the metal sleeves, potentially making it impossible to withdraw the bolts from the guibo. If the bolts run as shown, you only need to remove the nuts to remove the guibo with bolts still embedded. Then install a new guibo with new bolts.

If you install the bolts the other way around, opposite to what's shown in the photo above, that would have the bolt running first through the metal flange of the driveshaft/transmission and then seized solid into the metal sleeves embedded in the guibo making it difficult to remove the guibo later.

Nope. :loco:

Looking at it again, and again, and once more, they are NOT in the same orientation. This one is backwards.

Stamar, you want to see some guibo problems? Check out the Alfa GTV6 and Milano. You must be doing something wrong if you are having trouble with yours.

like other have said, never had any issues except when something was installed incorrectly. That being said, I always carry a spare with me.

really? like you're going to pull over on the side of the road and swap it out? lol :p

because racecar! I almost had my weekend ruined by busting one, luckily another spare...actually 2...its easy to make the same mistake twice

No kidding, went through two lower radiator hose last weekend at ORP before I realized I busted a motor mount. Luckily, it was a double header race, and I was able to use a friends PRO3 to finish the second race..
