have you got decent shocks? also, could just be the low nature of the very low first gear....hold on just a second, have you got your bowden tube
installed right? it needs a decent kink in it or you'll get clutch shudder on takeoff. if it's not long enough you could pack it out with a few
washers, or alternatively, use a kombi bowden tube which is about 10mm longer. I had this problem and the kombi bowden tube fixed it. Also, if you
have a tranny strap, the bowden tube needs to go around the outside, not underneath.

The bowden tube guides the clutch cable from the rear of the pan (where it exits) to the arm on your gearbox that you attach it to.

Mmm, so if I'm replacing the cable clutch with a hydraulic one, are there any "tricks", along these lines, that I need to be aware of ?

leave a bend in the hydraulic hose to allow the gearbox to move without pulling the hose tight (and breaking it).

Thanks Wes - am going to use steel though to the end end of the frame, then braided hose to the slave cylinder anyway, but will allow a bit more slack
in any case.

it's the torque of the engine twistin itself and the box and if the tube is not stiff will affect smooth clutch operation.
so for a hydraulic i would not feed a rigid tube through the bracket (exbowdentube bracky)
the twistin may kink and weaken it thus shortening its life...

Where did you buy your clutch plate from, and what brand is it?
I had a little shudder in reverse only and couldn't get rid of it. I had a cheap no-brand clutch plate. Once it exploded I replaced it with a sachs
clutch, and the shudder went away.

my clutch including clutch plate was custom built by the fellas out at albion clutch works. it definatly isnt a cheapo clutch plate as it was the best
clutch and clutch plate they had on offer ( its 5 pad brass button model with thicker then stock pads) the shudder in reverse doesnt concern me to
much as it is very minimal and only occurs on first take of

Lets just say that with a BRASS BUTTON clutch plate it will NEVER be as smooth as a fibre clutch plate but that is not to say that i would change it
with the power you have with the rotary it will be one of those things to get use too.

yeah it is only in reverse though taking of is smooth with no shudder of jerking or clutch catching ( took a lil bit to get used to the weight of the
clutch though ) and changing gears is smooth and fine with no shudder or feel at all. i am thinking it is due to being reverse such a low gear.

yeah, a brass button clutch will get those vibrations and be rougher compared to a stocker.
That's why I stuck with a stock 228mm sachs clutch plate. It doesn't slip and is very smooth.

Why bother with the steel line? Extra connections means more $$$ and more complications. We used a CNC Pull type slave cyl with braided line to a
3/4" PBR (cheapo!) master cyl. Never had a problem with it.
We still have it from the old car - I'll PM you.
