M Rear Suspension
Discussion
Hi,
Quick question, any reason the M does not use the second (rear) mounts for rear suspension?
I see the mount points are there on most chassis design and if they were used it would replicate the earlier Griff and also Tuscans that had dual mounted items.
In my limited knowledge would have dual mounted items help with keeping things less fluid and more rigid?
Given I remember replacing diff mounts on my 3000M given movement with torque would snap the mounting points.
Cheers

Mark, do you mean use the lugs that mount this seat belt mounting bracket. (Edited to say ...if you did not take the shell off the chassis then they are most likely still on the shell AND IMHO you do not want to remove them UNTIL the shell gets replaced on the chassis these brackets will align the shell onto those lugs, remove them and prepare/paint them afterwards. I have spare 'sets' AS, there are different versions for different models).

Yes...that is the seat belt mount bracket pick up point lugs....the other picture is of a Thurner chassis car and some have either single spring/single shock- single spring-dual shock or duel spring and duel shock (TVR aquired and simplified the set up from Elva which led to TVR trying different set-ups over the years) .

PS I doubt that dual spring M is a simple easy option as IF you put the top pivot bolt in from the wrong direction the nut clashes with the spring (I would hazard a guess that it would have issues that would need to be resolved first) I have seen it on cars, but not done it myself.

Was that seatbelt bracket used on later M-series cars only as my early 1600M has never had them from when I bought it 40 years ago? Perhaps it was at the change from static to inertia seatbelts. Geoff
I was just thinking the same, my 1600m just has bolts and washers through the fibreglass wheel arches. Might retrofit something like this if it was the norm on later carsGeoff, Tim,
That I know of, the second set of lugs are on all the M Series chassis that I have seen, (TBH I have added the anchor brackets to the lugs, on all the car that have not had them), so, unless there was an attempt to have two shocks, which as I have said, would require a little bit of forethought in reducing the length of the top pivot bolt and using a slim nyloc or the second shock spring clashes (I am not saying it is not possible to run dual shock/springs because I have seen them fitted).
With regards to inertia seat belt it maybe that there (90+ odd cars, 1300/2500/Vixen S4 with the M chassis) was an option to have them and these are additional brackets for the option.
Over the years there are 2 different anchor brackets, I posted a picture of the earlier version (although the second version is drilled differently for the 3 different versions of shell), here is my pattern item, for when I need to produce one given that they destroy themselves in the wheel arch over time!! (see the picture) and the then width of the 5mm plate allows it to be drill as required.

My 1600M must have lost that when it was rebuilt when it was only 7 years old! It has only ever had the belt bolted through a spreader plate on the top of the arch. Geoff
Geoff...They rot away, and need replacing... in the last picture that whole plate did, I have just cobbled it together for a pattern. A@ Gassing Station | TVR Classics | Top of Page | What's New | My Stuff
