Corse I rear suspension failure

LuckY I took today to check things over before driving to Stoneleigh tomorrow.
Rear right upper wishbone rear weld has failed/ripper.
The front mount weld is also damaged and allows the mounting tube to move left to right.
This allows the wheel twists and the damper spring then makes contact with the wishbone. Obviously the toe in goes all over the shop.
Anyone haD similar problems and how did they fix them?
Anyone know a good mobile welder in St Albans as engine will have to come out?
Anyone know any dimensions so I can make sure any welding is back in the right position.
Craig said something about beefing up Corse I rear mounts but I assume mine had been done?

Thanks

Yet another corse I failiure....

This has been covered a few times on here, or the old site. Yours has not been modified, See below how my chassis was modified by Arthur before I bought the car, as it failed 8 years ago..

I am not saying that this is the best way to do it, but this has worked for 8 years, including a few with the turbo engine... I did have to re-do one side, as when the strengthening had been done, the pivot tube was in my opinion not corectly aligned. I dont have any dimensions, but the tube should be parallel to & in line with the lower chassis rail, so horizontal & pointing straight forwards

Thanks.
Just need to find someone to do it, a I can't weld!!

I will buy some steel and start making plates like yours. What thickness please?

Here's a couple of pics of one I did about 8 years ago. I used an extra tube to brace the bracket & then filleted it inside & out with 3mm plates. This was on a Thema 8.32/Ferrari version of the chassis.

As I am taking the engine out, should I switch to one of your cable gear change setups?. Do you do 5 speed to fit the Corse tub?

Hi,

Slightly worrying to read this thread having just driven to and from Stoneleigh but after a quick check this morning found no problems with my car.
Another project now added to the list - will probably be much easier to modify and beef up in some way before any breakage.
Hopefully fabricate something with engine in with a view to improving at a later date next time engine out.

Bob, surely you've heard about this problem before?
Steve, that is worrying with so little use.
It looks as if the box section has actually torn from the photo. Is that correct?

The weld on the tube section has completely torn away from the tube. This allows the wishbone tube to rotate and this has torn the weld out of the box section. The white line is the shiny bare metal from engine side.

Hi John,

No not heard about this before other than knowing about Neil's/Arthur's which I had obviously wrongly thought was a one off problem.
Never mind there seem to be a few ways to rectify it especially as mine isn't broken yet.
