    Interested in the comments regarding the Safety Devices brace, which I fitted in conjunction with Reddish RACP strengthening plates. I just wondered why people feel it might not be a satisfactory solution when, as far as I'm aware, there haven't been any subsequent failures after fitting? Please don't think I am looking to enter an online row, I am just keen to get opinion/s from people who have more experience than I. :)

    From an Engineering perspective it shouldn't really do a great deal because it doesn't connect directly to the subframe bush itself or even to the panel that the bush is welded to.
    It will add something by stiffening the rear end and the panel it is connected to is actually in turn connected to the RACP.

    The difference with the SME Brace, as well as the Gosling and Mason is that they directly bolt to the subframe bush, this is much better for energy dispersion.

    For safety device :
    Pros:
    -immediate feeling of a stiffer rear end
    -serious build and strong
    -plate to we welded provided
    -4 points bolted is better than 2
    -overpass any 2 point bolt in bars

    Cons:
    -welding to upper panel could be tricky ( provided plate is thick, upper panel is thin...)
    -main barrel above rear strut are too high, impossible to reach dampening knob
    -main barrel above rear strut have a too big diameter, bolt can't be put without grinding the tube
    -after 50km, rear strut bolts goes off, after a toroughly tightening and 50km more = bolts goes off on more time ( could be removed by hand)
    -heavy stuff
    -upper panel welding and bolt in, dont correct the softness of the rear end panel ( as chris explained)

    In fact I have checked SME, safety device, vince bar and the CMP kit.
    Tried as a first step the safety device, but not satisfied of poor fitment ( grinding, bolts going off ) and at the not fully correcting the rear end softness.
    CMP looks satisfying, but fitment in chris's workshop and lighter kit finished to convince me, and including all the price is also competitive.

    At the end the safety device is not "bad" , but only not as good as I was expected.

    Road trip we can go together mate and he can have 2 convertibles to practice on! We can take which ever one he isn’t using at the time and test the ‘brace’ at the ring proper R&D that is :beer:

    Would the ‘weld in’ type brace be similar to the vince brace option for the convertible? I’ve heard the convertibles have a stronger RACP due to having strengthning to compensate having no roof but they still crack and lack of access to the rear strut towers would mean that only a weld in style could be the solution am I right I’m thinking that?

    Here are a few images of the Internal weld-in Brace in its JIG. This will be delivered part assembled as shown with as minimal amount of effort (and therefore labour) as possible required to fit it, the main work will be opening the floor section to gain access (same as with Vince's) and then re-fitting it once the internal brace is welded in.

    I try to make everything I do as simple as possible whilst also being effective, although sometimes what works for one doesn't always work for another.

    As if by magic the SME bolt-in brace also fits straight into the internal brace, allowing those that have already purchased the bolt-in to retain it.

    I really need to look at a Vert to see what's possible, I am sure something could be made to work. Then weld-in kit will of course fit, but it would be nice to be able to link to the turrets as well.

    Would you be prepared to sell me the above ‘kit’ I have an incredibly talented welder mate and could look at how it would fit in ? Just a thought .... I’ve seen that the vince guy offeres a ‘kit’ through other forums

    Sure, it will be available really soon. I am still finalising a few details before I go ahead and order everything for stock.

    I changed the design slightly of the internal weld-in kit today, I thought it looked a bit awkward....
    This is much cleaner and now has one main point of contact onto the chassis leg rather than two small ones. Both are shown in the pictures, lower one is the new design.

    Ordered the bolt in kit last week so cant wait for that to turn up. Would you say it would be ott to be ordering this as well or is the bolt in SME sufficient enough? Thanks.
