Vibra Technics : feedback

Postby akavia » Fri Jun 10, 2016 10:19 am

Hey - I have got 1.8T conversion, daily car, had the car for over a year now.

Originally the car had G60 front, gearbox and rear engine mount.

Initially upgraded front mount to Vibra Technics, VR6 variant, not the racing type, was impressed so changed gearbox and rear engine mount to Vibra as well.

After a few weeks subframe bolt came loose - fixed this. All bolts were properly torqued/tightened.

Now subframe bolt is loose again :'(

Should I change gearbox and rear engine mount to original G60 versions? To give more compliance to engine movement and help the chassis?

Would do you think? Its a everyday car.

Annoyed - Vibra were not cheap.

Hi mate I've got vibra all round on my mk2 vr6 and whilst I like it it's very very solid so I would say changing it would help you but it's only my opinion.

Front subframe bolts were loose (again).

Tightened them and now its ok, not excellent. If they get loose again then I will replace them with new bolts + Loctite.

I need to be gentle with the car, harsh or jerky launches causes the engine to knock. Not sure if its because of the vibra mounts since they are stiffer and the whole car is suffering.

Cheers.

Is the captive nut inside the chassis leg solid?

Yes and no.

Driver side is original one, as it came from manufacturer.

Passenger side weld broke off. So fitted a larger washer and nyloc-nut, rather than welding a new nut.

Gearbox mounting bolt was loose. Used spring washer this time. Got a new torque ratchet. Seems better now.

On the rear engine mount the mechanic used slightly shorter bolts, threads were just about engaging, don't know why. I got some new, stainless steel, longer ones from tool station, now drives much better. But the rear engine mount has some movement, squeaks, prefer it to be a bit more solid.

What do you think of early 8V/16V rubber mount + poly insert. See here;

I cannot see why even a solid engine mount would cause enough vibration to loosen a subframe bolt. I would suggest other factors may be the cause of this. I sell Vibra mounts at work and have never had this fed back to me. as stated earlier in the thread a double check of the subframe bolts and captives is in order. Hope this helps
