3000M Springs,shocks,discs & calipers
Discussion
)
Seriously (just for a minute), as I understand it, the M does use Ford / Triumph parts as some of the major elements of its braking system (TVR didn't manufacture their own callipers, discs, shoes, drums, etc. - as far as I know) but the key is knowing which bits are from where and, as typical of a small manufacturer, TVR changed this frequently (just look at the thread on here about bumpers!).
Certainly springs and shocks are specific to TVR as they need to be tuned to the chassis etc. and although it is possible to buy springs of any free length and rating you need to know what was originally fitted (or what is considered the current "best" option) - same with shocks.
The long and the short is that if you aren't sure get advice on each part and, in the long run, it may well save you time and money to get parts from someone who really does know the cars.
I've had mine (a Tuscan V6) since 1986 and have had just about every nut and bolt off it at some time and I still get caught out sometimes!

I started this thread, as I have two Taimars, one high mileage and well looked after but needs attention. The other, low mileage but has all the problems of being stored in a farm 'Coach House' for 14 years, mice, flat spotted tyres and porous alloys being the minor problems. A lowish milage scimitar GTE that has been in regular use seemed to answer a lot of the problems, if the parts fit I would have two problems solved in one. Am I living in cloud cuckoo land?
THE short answer is no the Scimitar has not got the same calipers/disc/shocks.
The long answer is from 69 on there was 3 different calipers used, early Vixens ran the TR4 set up 16p caliper, (imperial thread hose connection) AND disc (thinner disc and the caliper matches the disc in that the aperture is smaller). Later Vixens 69- and 72-73 M's ran the TR6 16p caliper (imperial thread hose connection) AND disc (for the TVR the 16p caliper uses the smaller shanked 11/16 head 7/16UNF threaded bolts AND SHOULD have large pad retaining hole and pad to suit), on M's IT IS IMPORTANT that the jump pipe from the hoses to the caliper suit the caliper thread...THEN the 73-80 car ran the 16PB caliper (metric thread hose connection with jump pipe to suit) AND TR6 disc. (again for the TVR, the 16PB caliper uses the large shanked 3/4 head 7/16UNF threaded bolts and should have the small pad retaining hole and pad to suit) Adrian@

I have a Scimitar SE5A which has the same front suspension/brakes as an SE6 but not an SE6A.
The calipers from the SE5A & SE6 are Girling 3 pot and also fitted to cars like the Rover p6B, Jag XJ12 series 2, Wolseley 6 etc. The SE6A has 2 pot lockheed brake calipers.
The brake disc on the SE5A/SE6 is TR6 and I think the SE6A is too but I'm not 100%. The disc of my SE5A looks identical to the one off my 3000S but I haven't measured them to make sure.
The front spring/shocks on my SE5A are no where near the same as my 3000S. Also the SE6/SE6A is a much heavier car than an M so I would have thought that would also count them out.
The only other part of the front suspension on my SE5A that looks identical, but ahain I haven't taken any measurements is the upright, trunnion & stub axle.
I did bolt one of my calipers from my SE5A onto the 3000S to see if it would fit, out of interest, and it does but I would imagine you would need to change the master cylinder as the caliper is bigger.
The bottom line is take Adrians advice and an extra bit of advice would be not to take any short cuts with brakes as I always think it's important to be able to stop.

Just to confuse everyone some more...The calipers from the SE5A & SE6 are Girling 3 pot and also fitted to cars like the Rover p6B, Jag XJ12 series 2, Wolseley 6 etc. The SE6A has 2 pot lockheed brake calipers.

The TVR griffith was homologated to utilise Girling 3 pot callipers a la Jag
It may be that your M can be fitted with the 3 pots from the scimitar??
