Thanks for that Richie

Looks a similar fix to what many of the american lads are doing. I remember one not so long ago getting fixed - the lads there made it look oem. Reason for his cracking though cos he had around 650 whp

Did 'you' just weld up the one side, or do both as the same time?

What do you mean Nords, I don't understand?

Nords · 21-03-2009, 07:27 PM

I know the crack was only on one side, but by strengthening one side only, would it put more pressure on the 'same spot' on the other side? I wondered if not put a strengthening plate on both sides of the car (not one 'below' and one 'above'). Does that make sense?

Edited to say: Like this?

I think the crack is on the car, not the subframe and the photos are captioned as N/S and O/S so I assume both sides have been addressed

Some of the guys in the US cut open the boot floor (as recommended by Turners repair instruction) - which then allows you access to the "otherside" of the subframe floor mount plate and weld up the other side and do further rust proofing.

They only do this to the most extreme cases of subframe floor mount tear though.

For those interested in the structural foam method the defect number on the TIS is 41 11 91 01 00
TIS 41 03 03 (025)
