What do u guys think?

Very interesting, but wouldn’t fit a one to the ///M

I can see the appeal but again no way would I put one on the M.

Really good SSK is all we need, plus i cant imagine the synchro's are going to like that setup too much.......

Looks beautifully engineered, would stop the missed shift i got today as hadnt driven the m for a while and forgot how far right you have to push the shifter from fourth to fifth, didnt think it was too much mone either ,except it would be the same but in pounds over here. Like most on here tho i think to put that in a standard M probably wouldnt look very good. In a focused track car tho , epic mod

The Zeds just not that kind of car IMHO. In a 600kg racing car brilliant.

Had an hour out in the M earlier, I just love that rifle bolt gear change, it would be sacrilege to remove that imho, it’s a fundamental part of the Zed M’s DNA:driving:

I’m not opposed to a sequential gearbox - I’d love a bike-engined Westfield - but I’d like to see a video of a car being driven with that attached. I suspect the “lightening quick” shifts would be baulked, especially on downshifts. It’s a nice idea and looks well-engineered but it won’t behave like a designed for purpose sequential gearbox.
You need mechanical sympathy to shift quickly in the ///M and I can see this leading to rapid failure of the synchromesh or other components.
I broke one of the cast metal selector forks in the gearbox of my 225 TT from habitually slamming the car into third gear under hard acceleration without due consideration for the fact that the gearbox was designed for pottering around not full bore upshifts. It had 80k miles of (ab)use in my hands before it broke and the selector fork was only around 8mm in diameter and cast from a porous metal, but it was clearly not fit for purpose in a car driven like the sports car it was pretending to be.

I would love a proper sequential shifter.
But to me this solution doesnt look that well engineered
Sure I can see why people could be attracted by a bulk of machined aluminium, but the shift action looks clunky with quite a lot of play. It looks more like an afterthought than something thats designed from the ground up (Obviously its exactly that, a bolt on solution).

I have no idea what something like this is going to cost (expensive I guess), but I would save op for a proper solution like a quaife sequential; that seems to shift more like a proper motorsport sequential. It basically works the same as a motorcycle gearbox (drumshifter for each fork).
And you can of course spec it the way you want in terms of ratio's and gear types etc (note straight cut gears in the video below for example)



Or a Drenth sequential but those things are completely unaffordable.

edit, I found the presale price on this bremer shifter and its $2.4k. After shipping, vat etc, thats about £2.4k, so not that expensive I guess (a quaife sequential is about 3 times that)

I should of put it in the lounge.
I wouldn’t dream of putting it in my car, just wanted to see what people thought. I like the gear shift the way it is in mine

Honestly; looks like crap...and cheap...who puts that in their car?

I see you’re ambivalent about it
