We get clutches mad especially all the time for customers.. we use sachs motorsport.... having "on off" clutches is just crap and completely unnessecary.

happens all the time at the pod just get over heated, but i still say its down to carless driving. allot of the bite comes from what material is used.. race clutches are not designed for cast iron

Mr Broster's Black Diamond clutch (which was new) used to slip under heavy load in his Corsa, it was hard work to drive because of this (it was adjusted correctly too, should have been fine) Too much power for it...
Paddle clutch in, no slipping, much better car to drive.
It's a tuned engine, the same as Butler is building, he's aiming for a bucket load of power, so he needs a decent clutch IMO, and a paddle clutch is the best way to go, instead of messing around with crappy 'fast road' ones.

you dont need anything special to have a good reliable clutch. its just when people think they need a powerfull clutch for whatever reason they just asume they need a paddle one. think of all the powerful production road cars out there that have nice light clutches.

if your building tuned 1.6's ie 200bhp, a twin plate 7 1/4 is the way to go

hummmm....... a light clutch can be achieved by the use of a hydrolic slave cylinder........ makes life easier.... also if a car is designed to have 400bhp it will have the design to put the power down onto the road..
then again have you ever drive a 172cup, the clutch in those standard is harder work than my awful pointless waste of money paddle clutch.
i didnt want to go out and spend money on a clutch, but i needed to, it took the fun out of driving the car.
if you have more power than standard on a buget car you will need to improve things like brakes and clutchs, its pointless saying you dont need to because you do.
you cant compare a fast production car to a modified car.

you cant be serious! im aiming for 240+bhp with my spec NA 1.6 16v. i will be using a helix paddle clutch, i wont have monumental torque so i will not be needing a twin plate clutch..... yawn

im not sure that high torque is a reason to use a 7 1/4".... just dont worry about it i must be wrong, either that or not all paddle clutches are awfull to drive with

my head work was carried out at my work, Jamsport
i can see why a twin plate would be benificial, but unless your into serious motorsport i personally dont see the advantage, if i had alot of power to put down then yes again i would see it as a must.
paddle clutchs arn't that bad to drive with. there is alot of rubbish about clutchs floating around and yes people dont need a paddle clutch on their nans micra agreed, but its a nice relativly cheap upgrade to any track car IMO

ive never been impressed with paddle clutches, we always get a sachs motorsport spec'd for poeple who want something a little bit better, also find if they do slip they fall apart.. so try to steer clear.

glad its working for others though, 240bhp 1600 is ideal for track too

Appreciate the advice. In all seriousness its nice to see the debate, obviously you both have different views and personal preferance is a crucial factor.
I am only assuming a twin plate would be more pricey than a paddle clutch. One that wont slip and handle track abuse well is good for me so the paddle clutch seems to be the right thing to go for, for now at least.
