I wonder if any of you guys can offer advice .
I have a GT3RS Sachs paddle clutch (single plate) which is very good, but also very heavy.
The box is a G50/20 with GT2 ratios.
I need a lighter clutch for someone who is going to do some stunt driving in the car (doughnuts J turns etc), and I dont want them to struggle with a heavy clutch.
I was told the factory master cylinder is 3/4", and that if it will fit in the GTR, a 5/8" one may do the trick.
Im open to any suggestions as to how I can make the clutch lighter.
The pressure plate is a 996 turbo unit.
The cars around 650 bhp, at 7300rpm, but its going to be limited indoors to around 6500rpm.

Changing the master cylinder will reduce the effort but will also reduce the throw so you will have to try it to check that the clutch still disengages fully.

Thanks Steve, There was a question in the other thread about whether the 5/8" cylinder would fit, do you have knowledge on this?Steve

A small point, this mod will reduce the effort but increase the throw. So you need to make sure you have enough pedal movement - or a long enough left leg!Steve

If it’s just the professional driver your worried about why go to all this trouble with no guarantee of a successful outcome.
As a ‘professional’ if he wasn’t strong enough to operate the clutch I wouldn’t be letting him drive my car.
Are you fitting ‘power steering’ for him as well?
and giving him a nice cushion!!!!!!!!!!As a ‘professional’ if he wasn’t strong enough to operate the clutch I wouldn’t be letting him drive my car.

If its a simple change of cylinder, then thats fine. The clutch is quite heavy in traffic, so if its an easy fix then fine. If not then bugger it..As a ‘professional’ if he wasn’t strong enough to operate the clutch I wouldn’t be letting him drive my car.

Now we actually have time to set things up properly concerning the car I may as well get the jobs done all together.
As to the driver...lets wait and see.

Just changing to a smaller master cylinder will give you a lighter clutch pedal, but with a longer pedal travel to get the clutch to disengage fully. There is no risk of damaging the clutch, unless it doesn't disengage fully, so adjust the pedal travel accordingly.
