Dream - You're gonna have to give us a bit more information than that. Have you got the car assembled with drum brakes already, have you bought the
tiger kit or are you building from book, can you weld, have you spoken to tiger.....

Dear Kingr,
I'm in the planning stage of my project.
I want to build a midengined bikepowered car.
I want to use the chassis and all the suspension of the Avon unaltered.
But I WANT rear disc brakes.

Hmmm, well, that would depend on how you're planning on interfacing the engine to the wheels and what running gear you're using. I believe modified
XR2 mk2 front struts have been used. As to not modifying the chassis or suspension, you haven't got a hope in hell as far as I can see, you'd need
to change the whole configuration of the rear end just to get the engine in, never mind if the space actually exists to fit it. There's no way that
you're going to make a front engined car into a mid engined car with out some severe alterations, if at all, you'd be better off making a completely
new car. Finally, why would you want to, bike engined sevens are rear weight biased anyway, why make it worse, you'll just at best make the steering
go iffy under acceleration and at worst make it wheely under acceleration, not pleasant at all.
Hope this hasn't pissed on your bonfire too severely. You'd be best talking to the middy group about suitable uprights if you're still determined
to go ahead.

Dear KingR,
You don't really give me much hope.
My intention is to mate the bike engine via a very short propshaft to the standard sierra diff.It is not so complicted as you think.I know at least
one Midtec Spyder wich has a configuration like this.The engine is thus placed North-South and NOT transverse via a chain!!The Tiger Avon chassis is
very suited to this.Just chop the backbone and hang in engine and triangulate the rest voila.The seats must be moved forward,shorten the steering
rack.
Why is it so difficult to have rear brakes on the Avon?

Is this some kind of pre-emptive 1st April?

If I was you I wouldnt drive the engine to a sierra diff if you are making it mid engined.
Instead use a chain and save yourself around 30-40kg.
Also you will gain more power as theres less friction in the chain than a diff.

Dream, it was addressed at you. I'll try to moderate my comments here. While I have no doubt that it is fairly straight forwards to connect a
motorbike engine close to a sierra diff, it seems like a bizarre thing to do in the context of a front engined car. You say that you don't wish to
change the chassis or suspension, and that you're just going to move the seats forwards. Well, transmition tunnel aside, you'd have to move the
seats, I would imagine, at least 2 feet if not further forwards. This would mean you have to move the footwells, steering column, scuttle and probably
numerous other things. Just extending the footwells would be bad enough for most people without having to create bespoke scuttles and the like. The
midtec spider was designed specifically as a mid engined car, the tiger wasn't, you can't really compare it. To be honest, fitting disc brakes
should be the least of your worries. If you're determined to go middy, why not just by a sylva or something like that?

The information that I gave was given in the best of faith, if you wish to ignore it, then fine. It was, and still is my feelings that it's important
to give more than just the bare minimum answer, as with so many things, there are often things that you may not have thought of, but someone else has.
Equally, when I feel that someone is embarking on something that they do not understand the full implications of, I at least try to inform them of
what they're letting themselve in for. Again, you're free to ignore me, but don't expect sympathy if it all goes titsup. You obviously have a
different view from this and only wish to have the barest minimum answers from the barest minimum of questions, so : "What is the best way of fitting
rear disc brakes on the Avon?" By taking the wheels off putting the discs on the hubs and bolt the calipers on.

So peace brother.
