Popular Post keith84_hk Posted August 10, 2021 Popular Post Report Share Posted August 10, 2021 Hi folks, I am developing a short shift adaptor which will fit all V6s with EA60 gearbox. The idea was taken from LotusTalk where you move the original pivot point inwards the shift lever, to create a shorter throw, which reduces the vertical (forwards/backwards) throw by approx 30%. More info below LINK : https://www.lotustalk.com/threads/short-throw-shifter.123965/ But instead of drilling the lever, I decided to make an adaptor which requires no drilling or risking damaging the lever. So the first prototype arrived a week ago and I have waste no time to get it fitted myself and I am so happy to say it WORKS! And it works brilliantly! The shortened throw reminds me the good old 997 GT3 shifter although the Porsche still has the edge in terms of 'Short' throw. The change feels more weighted as well as you now need a bit more ''push'' to change the gear, but which I am talking about a TINY amount there. Although the adaptor now fit tightly with the lever but there are few adjustments still needed before I can get it perfect, so more updates will follow 4 Quote Link to comment Share on other sites More sharing options...
KIMUTAKU Posted August 10, 2021 Report Share Posted August 10, 2021 Looks well made and a proper short shifter solution for the community! Quote Link to comment Share on other sites More sharing options...
TBD Posted August 16, 2021 Report Share Posted August 16, 2021 Love it! Keep me informed and put my on the order list. BTW: That was my post on Lotustalk. Meanwhile into the third Lotus and would eagerly do the mod again. 1 Quote If you have the choice between a Stairway to Heaven and a Highway to Hell don't forget the Nomex®! Captain, Lotus Airways.

keith84_hk Posted August 17, 2021 Author Report Share Posted August 17, 2021 @TBD Kudos for such brilliant idea! Surprised no one actually make the move of the adaptor so I thought I'd give it a go. I will be receiving the second mock up by next week and will keep you posted. I have no intention to make money from it so I am going to make few and give it to anyone who are interested @TBDyou are on the list indeed. 1 Quote Link to comment Share on other sites More sharing options...

Gold FFM C8RKH Posted August 18, 2021 Gold FFM Report Share Posted August 18, 2021 Would this work on the Evora too? Just a thought. 1 Quote I came into this world screaming and covered in someone elses blood. I'll probably leave it in the same way. Link to comment Share on other sites More sharing options...
keith84_hk Posted August 18, 2021 Author Report Share Posted August 18, 2021 Yes it will, we're all using the same EA60 gearbox with the same shift lever. Just the crossgate lever is different for later models (Exposed shifter) but we are not touching that here. Quote Link to comment Share on other sites More sharing options...
Martrack Posted August 18, 2021 Report Share Posted August 18, 2021 What is it made from ? Would have to be solid enough not to fail / break, especially considering the additional "push" needed to engage the gear. Many thx 👍 Quote Link to comment Share on other sites More sharing options...
keith84_hk Posted August 18, 2021 Author Report Share Posted August 18, 2021 The current mock up is 3D printed in Stainless steel, but I am thinking CNC it in aluminum for the production batch. Should be robust enough? Quote Link to comment Share on other sites More sharing options...

Should be robust enough? The cylinder on the adaptor is fairly thin (5.5mm), depending on the hard push I wonder whether or not aluminium would finally break here... Stainless steel would be much stronger, but certainly at a higher production cost 😐 Quote Link to comment Share on other sites More sharing options...

Leon Posted August 20, 2021 Report Share Posted August 20, 2021 (edited) This is a great idea and saves drilling the actuator arm. Nice one!! Count me in too for my Evora 👍 Edited August 20, 2021 by Leon Quote Link to comment Share on other sites More sharing options...

Mark.A Posted August 20, 2021 Report Share Posted August 20, 2021 Hi Keith, Looks like you have made a popular part for the EA60 gearbox shifter. Great idea from @TBD and for you to develop it in to a working prototype. I know it is a work in progress but as @Martrack has pointed out there is a sharp corner where the pin attaches the body this could be a stress point in the design? Once you have developed the finished part I would also be interested in one. Will be following this thread with interest. Quote Link to comment Share on other sites More sharing options...
keith84_hk Posted August 20, 2021 Author Report Share Posted August 20, 2021 Hi Mark. Thanks for your input. I think @Martrack was concerning about the material strength which we are now going to make the adaptor from a one piece solid CNC stainless steel. I understand the new shift point could stress the original arm/lever so if you look at the design, the adaptor was actually covering most part of the arm/lever so the stress could be spread across instead of at one single point.

rmaurer Posted August 20, 2021 Report Share Posted August 20, 2021 That's a great idea and is very similar to the short shift modifications performed to Renault Sport Meganes! Please can you add me to the list, happy to cover any costs. Quote Link to comment Share on other sites More sharing options...
keith84_hk Posted August 26, 2021 Author Report Share Posted August 26, 2021 @rmaurerExactly, it is not something new and I've seen the similar thing on other cars. Will put you in the list mate. I think we have 10 people now and I will give you guys update soon. 2 Quote Link to comment Share on other sites More sharing options...
