I'm still struggling to see how something with large-span triangulation like the Zcars / Minitec is little-to-no better than the thin span on the AMT. Just to be clear I am not stating that one configuration is better than another just the thought process which lead to the choice I made, be it right or wrong, both have advantages / disadvantages. I have simulated 0.9g braking and 0.9g cornering and in the configurations. Talking specifically about the top arm on the Minitec / Z cars or any frame with this kind of top arm joint spacing: By making the joints seperated by this amount (not that dissimilar to the standard A series lower 'arm' arrangement, but definately a step further with the Minitec arrangment) we pretty well if not totally decouple how the longitudinal (braking) and the lateral (cornering) forces are fed into the upper arm joints. I have no idea what gauge / type of tube is in the Minitec subframe or what it weighs, my subframe still weighs just over 11 kg (If I keep the shear panel it will add another 2 kg once lightened). The original XE subframe I took out of my car weighed 33kg, Watsons subframes (Metro / MGF based) weigh in at 30kg before Watsons add additional structure for the Honda engine mounts - I have weighed these myself so am confident in the numbers. The Z cars link you posted is for a RWD engined car so they can add a completely uninterrupted frame work out to this point as there is no engine to get in the way. The following images show the additional mount (outlined in red) that were always intended but have only just been made, this tube will be integrated into the bulkhead, it falls nicely into the corner of the bulkhead but will have additional metal work tube/s to spread the load fed into it the bulkhead better ![]() Basically a long 12.9 bolt goes through the tube in red, through the upper arm spherical joints and through the subframe ![]() Incidentally the red tube is much longer than it needs to be, I will cut it back once it is fully integrated into the bulkhead, the yellow line is the approximate position of the bulkhead to give some idea of how much these additional mounts stick out. It helps the rear part of the upper arm especially and will reduce the twist and lateral movement (the washers are temporary as I appear to have put the 'proper' spacer somewhere safe :) ) Cheers Edited by Aubrey_Boy on 13th Jul, 2017. |

RESPECT!!!!! Looking at the images above, I believe you do have at least 25" increased span, maybe as close as 50% over the AMT frame. I also did not click you were intending on using K-series hubs - what are the major differences - i.e. what is the most significant improvement over the mini hub? Is it the KPI relative the the hub axis, or a reduced distance between the swivels or something else? I am loving the details of your build btw, and looking at the pictures of welding is an inspiration. I can't wait to see the final exahaust manifold all welded up. Are you doing the welding yourself? Can I ask what rods you use for the T45? Hope im not intruding in the build, but i built my latest frame around k hubs for the scrub radius improvement. Did this after me and Abs (16vminiclub) put our minis back to back, each in each others cars on the same road. We both had ~200hp at the time, and i was on A(metro) hubs and him on k hubs. difference was staggering. not to mention, larger wheelbearings better balljoints and much larger CV joints :) ![]() awesome build, never much liked the really narrow, single sheer mounting points on the inner of the upper arms on the AMT frames. turbo 16v k-series 11.9@118.9 :)

This is super-interesting. Are the K-hubs the same layout as the mini hubs - i.e. similar taper, similar distance between the swivels?

Cheers TurboDave, as far as rods go it's just the standard industry recommendation: A31 if NOT heat treating A32 if heat treating All of the TIG welding is done by a good friend, he's a Motorsport fabricator but with the build up to and the race season now having started it's getting difficult to get stuff done. I'm ok-ish with a MIG for body related stuff but intricate work like the manifold and safety critical things like the subframe and suspension I just couldn't trust my own efforts. TurboDave16V said:
I also did not click you were intending on using K-series hubs - what are the major differences I mentioned earlier that I had to rethink the coilover layout, the main reason is that I really want to keep the track width sensible and in doing so I couldn't get the lower coilover mount in a position to give the behaviour I wanted, tbh for a good while I had admitted defeat and just accepted what I had. As more parts were positioned I mocked up a few options and decided on what is shown here: This is the centre mount for the horizontal coilovers, the tube coming out the back is just to reduce the subframes main lateral tubes tendency to bend / bow when loaded, it will be stitched into the main crossmember in the bulkhead, because the coilover is near parallel to the tube most of the force is dealt with by the subframe tube itself. ![]() They also reduce the unsprung weight and the weight of the coilover is much lower in the car, no question ride height / corner weight adjustments will be a PITA, but proper wheel rate behaviour is more important than convenience.

Just interested how it felt as a direct comparison on the same car with your previous A series Metro hubs / steering arms. Did you use all the whole K Metro subframe & parts or a bit of both?
