Solid Gearbox Mounting !
IRS Beetle Solid Gearbox Mounting !
Has anyone done this in a Beetle, Baja or Buggy ?
Either front or rear mount or both of them ?
Im fully aware of the noise and vibration factor.
Has anyone got stories or better still pics ?
Can someone tell me what the advantages are of solid mounting over rubber or urethane mounts ?

When the poly-urethane mounts crumbled on No.8 Beetle a couple of years back, I solid-mounted the gearbox.
The 2 rear mounts [nearest the engine] were just a case of replacing the rubber bit with steel. I used the original cradle, and welded 2 channels[with nuts welded inside to take the 4 gearbox bolts] onto it. It was easier for me to bend up the channels, but they could be cut from RHS.
The front mount is attached to the row of bolts that hold the 'nose piece', and I used 2 shock bushes at the outer ends.
I'd rather wear a Beetle out by racing it than by polishing it!

Thanks for your response,
Does it feel different on the road ?
Have you had any cracks or issues yet ?
How long have you had it done now ?
I have solid mounted mine already during a ground up rebuild but am double questioning myself as you do ! haha
thanks

No.8 Beetle is a track car, but has had solid mounts for about 2 years. Last May it had some 'destructive testing' at the Nationals Supersprints.
There was no sign of any gearbox damage as a result. Have you braced the chassis fork?
Can you post some photos, then we all can 'pick it to pieces'.
Cheers, Greg

Just be careful if you only have a mid mount (solid) and the "banana" mounts are still rubber etc........what happens is the motor's torque is
trying to twist the Gbox case as the engine end is still able to move......not good long term.
Also re solid mounting for the road....expect your tinware to crack and tight bolts to loosen due to the vibration. Its like a harmonic vibration, you
can't really feel it but its there !. I found I had to loctite a lot of bolts on my hillclimb car as soon as I went solid mounted.
What is your vehicle going to be used for ?

I will be running a EJ22, I currently have a standard solid rear mount and mid mount (4 bolts) with no nose cone mount !
Is it legal to have solid mounts ?
I think I am turning towards Standard HD Rubber mounts on the rear and nose cone !
What are your thoughts on my set up ? Should I change back to rubber ! Majority on road driving with occasional off road sand and rocks !
It's something I want to get right the first time and not have to rip off the body again to replace parts that have only been fitted a short while or
worse still rebuild a gearbox due to cracked casing !
Thanks in advance for your opinions.
