Subframe mounts MGF

What's the dela with subframe mounts on an MGF?

Do they deteriorate? What happens when they do?

How do you fix them?

TT MK7 exhausts for MGF and TF sold out next batch ordered. .

They don't rot like MGTF ones do.. as the water doesn't get in due to the rubber

The rubber perishes though and can allow for movement

Most people who are looking to 'upgrade' for fast driving/track days swap the F ones for TF solid ones.. as the subframe mounting to the car via solid mounts improves handling

The TF mounts (especially the forward facing ones) however rot for fun

I created my own 'cyberman' mounts... basically TF mounts (brand new) sleeved with 3.4mm seamless tube, spot welded and seam welded into the TF mount for extra strength and will take a lot longer to rot through

Ive also fitted sealed plastic bungs too (no water in, no water out)

There are stainless ones for sale.. but some debate about how strong they are compared to steel

The car is a 96 F
I'll check them for rot either metal or rubber. Would their rotting explain the car trying to steer itself under braking and not being stable at high speed on the motorway?

Car is currently hardly driveable

(Possible a stupid question here, but...) have you checked out the EPAS? Sounds a bit like a knackered assistance motor!
Just a thought.

Check your rear wheel bearings & play in the rear suspension, ball joints etc. if it's unpredictable handling it is more often the rear rather than the front.

when I took the mounts off my MGF the rubber had split all the way round, couldn't tell when they were on the car, I'm in the process of changing mine for some TF ones and following in DD's footsteps have "cyberman'd" mine too as its an awful lot cheaper than buying heavy duty ones that are no better

I know that the TF front mounts rot as already mentioned here,but can the rears also rot/wear to allow movement?

The rears (4 holes) are thicker to start with.. And as they face backwards don't get anywhere near the same punishment

I've only ever seen fronts rotted away..

My rear rotted away and had to be replaced.

Err...That doesn't sound quite right somehow!
