Lotus 7 S4 dual master cylinder conversion

[crafty]

Does anyone know of an off the shelf conversion from single to dual master cylinders for the S4?

Q1) Who have you contacted so far?
Q2) Will it be different from an S3?
My starting point would be John Watson of http://www.lotus7register.co.uk/.
Obviously there will be knowledge within the http://www.lotussevenclub.com/. Are you a member? Sadly there are few S4s about, so the knowledge is more limited.
Next would be the LSOS (Lotus Seven Owners of Switzerland) because I saw more S4s in Switzerland that I have in the UK. Braking on Swiss passes is highly critical! The local agent is Fredy Kumschick
Lastly, I do know someone with an S4 who is also an design engineer at JLR, so might be able to help. He has rebuilt his S4, which he has owned for decades and might have improved the braking system.

I see you are HK based, so you will have more difficulties on the parts and agents front. Isn't e-mail a blessing?

Hello Crafty, would something like this work?

You won't have room to run two masters side by side, you'll foul the triangulating chassis rail. You could run something similar by fabricating a lever and running the masters facing the other way, on top of the bulkhead. Alternatively you could cut into the bulkhead and install an after-market pedal box in its entireity, that way you'd have better pedal ratios etc too. There is obviously a bolt on option as some cars came with twin-circuit standard. The ones I have seen interfere with the air filters though.
