I have been told by Peninsula that a small hole has been found in one of my outriggers when preparing the chassis for a fresh coat of waxoil. Their comment this eveing was that a body off job may be necessary to repair it.

Once i regained conciousness i asked them to email me a picture of the effeted area, which they are doing tomorrow.

Im sure I can recall a discussion on here as to weather it is necessary to take the body off to repair the outriggers. If anyone has any experience or opinion on this i would be grateful of any advise before dicsussing my options with Peninsula.

Last winter they had the car in for a coat of waxoil and the mechanic told me my chassis was in very good condition and that i shouldnt have any problems with it!

This was done body on. Its the front drivers side corner behind the wheel. Both round section and square section badly holed. The garage didn't want to lift the body.

When I had mine done, one of the original options was to do the work with the body on, although they said they would have to cut into the floor and then repair it.

I opted for body off as an opportunity to do other work with relative ease. It was probably the best thing I did, as the full extent of the problems could not be seen until the body was lifted.

Watch out for the dreaded cracked welds!!

There is an an article in the maintenance section of the tvrwedgepages about outrigger repair. Is the problem with the 400se the lack of access to the outriggers because the sills are not removable?
If the damage is just one small hole and the rest of the outrigger is sound would it be possible to weld a small metal repair.

I replaced both outriggers body on. Followed the advice from Wedgie and saved myself some big money in the process.

I too was told by a reputable TVR specialist that it was a body off job. I did all the prep work myself and left the welding to an expert as that's the most important part of the job.

The only downside, is that I discovered my interior was rotten when gteeing access to the sill bolts so I thought I may as well do the whole lot during this winter including a respray!!

The body off for a small hole seems a bit excessive to say the least!

I always wondered if it would be possible to repair the outriggers using angle iron. I guess its where the repair is needed though which will probably be in the most inaccessable area.

Ouch - sorry to hear that Dave.. need to confirm how big a hole this is exactly and where it is positioned on the outrigger - Richard will know what your options are.. but with the body off they can thoroughly check the rest of it to ensure it is all caught.. incidentally - Gerald is right, the sills are not like those on the 350i, ie you have to cut them off to get access (depending on location of problem) which then means body repair as well .. if you take the body off you are likely to have some stress cracks from the movement - unavoidable but then you will get cracks eventually through normal use.. I tied it in with other work to cut down on labour (rear brakes, bushes etc etc etc..) but still not cheap... even though they checked it last year rust doesn't take much to manifest itself annoyingly.. little consolation - hope you can get sorted for as little grief as possible..

Forgive my ignorance but does it really matter ?

Does that mean it fails an MOT ?

I have seen lot's of comments about chassis problems, mainly outriggers, and some of the measures taken seem a bit drastic.

If a small hole that's accessible then weld it up or bung something in it and paint over it. I am probably wrong but surely the outriggers are there more to hold the body than for any impact protection or overall chassis strength. I am no expert at all (as you can probably tell) but unless they are likely to fall apart or you want to have a car in A1 condition then certainly if body off is the only way to repair then better to wait until a few other bits can be renewed at the same time and go for a full sandblast / powdercoat restoration ?

BTW IMHO the answer to protecting the chassis is in my previous posts about the CAT electronic device - 150 odd quid against a body off job seems a good bet.

Dave's car is really immaculate - so I would guess he would not want to paint over it ... the outrigger on a TVR does form a major part of the side impact protection too..

If it's not just surface rust and you have a hole - then the damage is probably much bigger than you can see .. I'm sure JMorgan will agree (see photo..).

I'm pretty sure Peninsular can be trusted to tell it like it is !

well iam in the middle of replacing the outriggers on the 350 ,its fairly easy job if you got removable skirts ,i noticed quite a bit of rust came off when scrapping the tube around the front section. so i decided to take the skirts off only to find the back plate had gone on the near side not so much the tube , but on the offside the plates front and back had gone and about 8inchs of the tube .so iam gonna renew the lot on both sides then i know they have been done so far its cost no more than £30 new tube ,plate and bolts. i suppose they wernt in to bad a condition for an 18 year old car !a lot of the tube which i cut off was in good condition just seems where the plates were welded onto them they had rusted through .
now as for a body off it carnt be as bad as taking the body off a 1960 Grantura which ive had to cut the fibre glass to reach the chassis not looking forward to re glassing the body back to the chassis .

Frist of all thanks for all the advise. Spoke to Peninsula today and they have had a thorough look over the chassis again. There is only one small area that needs replacing and they have advised the most cost effective way to do it is to cut a hole in the GRP in the drivers footwell a few inches across to get access, replace the knackered section and reapir and paint the GRP. Once completed there will be no visable evidence of the repair.

They have quoted 6 - 8 hours to do this with a cost between 300 - 400 + VAT. I simply dont have the spare cash to do a body off job and they now think that would be overkill for one localised area of rot, so Im going to go with this suggestion.

They have promised to take photos of the repair at various stages. When I get them I'll post them on here for anyone whos interested.

And the outrigger holds the rear hub reaction arm! So all loads under acceleration and braking are fed into the outrigger. Best to make sure it is really ok. And better to do it once and good, instead of having to worry the next year again.

Dave sorry to hear this but I guess it's something we must all expect sooner or later. I have it from an authority (aka Seamus) that a body off job is likely to cost £1500 minimum which is a heavy bullitt to bite for anyone. Hope the lighter repair turns out OK, don't forget it's got to support those heavier wheels

Dave,
Post the photo and I'm sure clear advice will follow though on the sound of it the body off option for a small hole does seam OTT though as Nacnud will testify Penninsula are generally on the money with these things.

I had both outriggers and seat belt anchor points replaced by Peninsular. Admittedly this was done on my old 350i, so didn't need access by body removal.


They did a very good job too.....and it was nice (uh hum)...when i finally got the car back..!
