Grantura shocks

[dexy]

Any one know what the shock absorbers are off from a 1960 Grantura ,are they from the beetle that the suspension was taken from ,any idea of a newer alternative and if so part number etc etc .i have the old ones but they have been painted and i carnt see any numbers on them.
cheers neil

Hi dexy,

a detailed part number for shocks usable for the VW suspension Grantura is unclear. I tried to find out a successor of the original Monroe shock fitted to my car. Unfortunately they could not help. I repainted my Monroes as they were in a good technical condition. I'm still looking for new bushes for the lower shock mounting. David Gerald offered me Koni shocks two years ago. A friend used standard Mini shocks.

Try the Grantura Register Sales & Wanted page under

perhaps anyone can help with more information.

Spax must make them, because I have them on my MK1?

[mawds]

could they be revalved? - probably cost more though

[dexy]

i think ive got to the bottom of it ,ok its a VW suspension so ive gone for vw shocks to fit ,i gave one of shocks off the car to my friendly part finder and he gave various shock makers the dimensions of my shock to which Boge came back with a shock that matched .ive got the shocks they seem to fit .So the part no for the Boge automatic are 27-162-8 if any one has any difficulties trying to source them drop me an email.
thanks for the replies
cheers neil

Spax do make the shocks I have just ordered and fitted them to my car. They are gas filled so ok for road use but not for fia racing. I have the numbers for them if you still need them

I did the same a few years back - had my Monroes reconditioned/repainted, cheaper than buying new and no hassle trying to find a match for them.

Hey, could you give me the spax details?

Hi
Phone spax on 0906 302 7729 and ask for G4.5LL shocks and sleeve 0060332. They will confirm they have them in stock and give you a company to call to order them as they do not sell direct to public. Any problems email me back. Hope this helps.

Hi
You will probably find that Avo and Gaz could supply these as well, certainly Gaz offer a coilover with ride height adjustment and 36 damping adjustments using oil rather than gas that fits the 1800S and Mk3 for £70 plus the dreaded VAT.

You will also find that Gaz would make shocks to suit just about anything if asked.

BTW I think that you will find that most of the manufacturers use gas in their shocks in one form or another including spax but IMHO this would not go against FIA rules because in particular Spax talk about Krypton gas but its only in a small bag to stop foaming of the oil when it gets hot.

I have been looking at the FIA regs and they say nothing about gas shocks. I believe you must only fit items which were fitted to the cars when original, and raced in that spec. If you can find information on a car which was raced and bring proof to the FIA then ypu may get gas filled shocks added to the homologation sheet. At present I nop of nobody who has this information so gas filled shocks are out.

Do you have any details of AVO and GAS shocks as part number or name or type?

The listing for the 1800S and Mk3 are GP5 2282 front and GP5 2283 rear, we are talking 81.37GBP including VAT

I think if you do your homework you will find that Grantura Mk3 suspension is totally different from Mk1/ Mk2 suspension. Also although Mk 1/2 suspension uses VW tosion bars the valving in the dampers is not the same as VW Beetle and therefore the dampers quoted as suitable for VW will bolt onto the TVR but will NOT work correctly. sTeVeR

Hi im restoring a MK11a and have just brouht a set of spax using the part no given by walkonneil (spax confirmed correct) from my local Halfords for £59.95ea

[mk1S1293]

Hi mates,
I am restoring a Mk2A FIA car me too.
Original TVR FActory leaflet for the Mk2 and Mk2A refers to Koni shocks absorbers that now are KONI CLASSIC.
Anyone has an idea of KONI CLASSIC suitable codes?
I bought my car badly dismantled and having some worn Monroes.
Front ones looks longer than back ones but who dismantled the car did not indicate which is for.
Do SPAX shock absorbers comply to FIA Appendix K rules?
Thanks in advance,

F

Can't help you with the numbers but any Spax shocks will have to comply with Appendix K to get HTP ie steel body, single adjustable, oil filled and without ride height adjustment (although we generally use adjustable spring platforms and machine off the threads when ride height is set)

I was not aware the Mk2a was FIA homolated, I thought it was only the 1588, 1622 and 1798 Mk3s under 32, 68 and 160 but what I am happy to be corrected

[mk1S1293]

Hi,
Homologation papers reference number 32 from April 1961 is the correct one for the Mk2A Grantura.
It states GTS category and there are a couple of amendments referring to light alloy wheels, HRG head with 40dcoe Webers.
I hope this helps.
