Need a new set of boots for the S - I'm going to use Event Mobile Tyres as they do a good price on those Dunlop BluResponse and it all gets done on my drive.

Don't trust anybody to jack the S though - can just see a trolley jack on the outriggers or worse still the fibreglass itself... eek

Don't have any spare wheels to swap on, so the plan is to crack off all the nuts, jack the front end and get the wheels off for him to do out the back of the van, refit each as it comes off, then, drop the front and jack the back end and take the wheels off. Hopefully he won't mind a 5 minute wait in the middle as I "swap ends"...

I know I can jack on the front crossmember, but was looking under the back of the car today to see where I can jack. Fortunately I have a V8S style exhaust with pipes separated more than the standard V6S, so I think there is space to get to the chassis crosspiece behind the diff - is this OK to jack on?

Don't want to jack higher than necessary so there won't be room to get axle stands underneath but will put something under the outriggers in case it slips on the jack.

Be interested to hear how others have had their tyres changed on their S's

Might be wrong here, I'm sure someone will be able to confirm.
I use carpet between the jack and chassis to prevent any damage.
The outriggers shoulld be strong enough at either end (not in the middle) to lift the car.
The further inboard you get the better, just use soft stuff to spread the load.

Jack the car on the outriggers.

The mobile guy who did a rear tyre on Tamy used an airbag on the outrigger to jack the car.

I cut four eight inch long boards just slightly wider than the chassis. I then glued half inch thick pieces of rubber onto the boards. I then lifted the car using the points suggested in Heath's book.

If I had that little confidence in a fitters ability I wouldn't let touch my wheels and tyres either!


Talk to the guy, suggest where you'd like him to jack from, if you can muster two jacks between you I'd jack the rear on the big tubes that the trailing arms pivot off

I only jack and support the car on the main chassis members, for starters they have a nice flat section to help spread the load. I also chock the wheels that are still in contact with the ground. As mentioned on here, a nice soft cloth or pad to protect the precious chassis thumbup

I also have non standard exhaust and I always jack on cross member behind the diff - make sure you are NOT looking at the petrol tank cradle though. This has advantage of jacking both sides at once and allows axle stands to be slipped onto the angled chassis rail that runs from this cross member forwards and outwards on each side. Simples

OK, so if I jack a corner at a time, can I jack on the outriggers if I get the trolley jack as close to the centre of the car as possible? Or is it better to jack on the main chassis itself. Just worried about stability with the jack being so far inboard...

If you can muster 3 jacks it's easy.........



It won't fall over, it won't collapse and you won't bend or damage anything smile

The mobile guy that did mine had an airbag 'jack' which is great for spreading the load. Had no problem with him doing it.

Well in the end he used an air jack on each corner of the outrigger and it was fine. He really knew his onions and had done quite a few TVRs before. He protected the chassis too.

Will my trolley jack go under to the front point or do I need these?

Just a cautionary tale. If it has been waxoiled it will be very slippery. (My jack slipped and went through the rad)

There is 5" from cross member to floor on mine, plenty of room for a "normal" trolley jack.

Another good reason not to soak everything in that gungy muck that is supposed to be inside chassis members, sills on steel bodied cars etc.

I bought a low entry high lift trolley jack so I could get the front end onto axle stands when I did the clutch slave cylinder.

Rubber pad on my trolley jack protects the chassis.

Just a word of caution from damaging experience! A few of you may remember a post from me almost 2 years ago when I missed the Barn Farm run at the last minute. Many DIY jacks have pivots held in with circlips. One on mine was faulty (the groove in the pin had not been cut properly). I had the car up and was just putting a stand under when the pin came out and the jack head dropped to one side. The wheels were still on but the car slipped sideways and the stand broke a lug off the diff, oil everywhere, heart rate suddenly elevated, and no way of lifting the car with the jack and stand now stuck under it!

Moral: check your jack. If it has circlips then check they are in properly or preferably do what better quality jacks do....weld the pins to the side arms.

I used Event Tyres before on my old V8S - they were excellent I will be using them again.
