What year did MMC redesign the chassis to eliminate cracking Nd bump steer? Not bolt on mods but a complete new chassis coming out of the factory..

Good Question LightSpeed. Doesn't the parts and modification document added to the M3W section in this forum cover that.....? https://www.mtwc.co.uk/wp-content/uploads/2020/07/Final-150.pdf

Mid-ish 2014 onwards as far as I am aware, constructed using improved materials too it seems - and probably better made all round. Also supplied with a newer design of suspension upright that raised the steering mount points to have the same alignment as the Comfort Kit 'upgrade' that was previously avaolable.

Two separate issues I think Stephen. The bump steer being largely reduced but not completely cured by the addition of MMC's sarcastically named "comfort kit" which brought the track rod angle from steering rack closer to horizontal when static. This was offered early in production as a short term fix for early models, later corrected by different uprights which achieved similar. Most other changes/improvements including chassis took place late in 2014 when the NVH kit was introduced, with chassis upgrade kit also becoming available.

Also supplied with a newer design of suspension upright that raised the steering mount points to have the same alignment as the Comfort Kit 'upgrade' that was previously avaolable. I suspect that the factory also produced some hybrid chassis used for replacing those in early models that were cracked - our M3W is a very early 2012 example and the replacement chassis has the hard bolted (no NVH) bevel box and a front geometry that uses the very early Suplex shocks with a comfort kit that retains the low ride hide but better steering arm geometry and of course all the bracing...

Agreed - I was also told my MM it was a Hybrid chassis (2014/15) which replaced the early 2012 cracked one - they then replaced the body hence MOGster is a fairly unique 2012 with 2015 Hybrid chassis and 2016 body complete with louvred tail.
