Heavy duty clutch springs
 

Is it possible to get heavy duty clutch springs for the early 583 engine?

I know Suflex springs from a 916 fit as Matt borrowed mine at Donington several years ago and I never got to see them again, although he did pay me for them 3-4 years later
I suspect his ex championship winning 583 engine sat in garage contains them.

Try Avanti Racing http://www.avantiraceparts.co.uk I use a set of heavy duty ones from these guys - albeit for a 620 - and they work really well.

Do you know if they would they be the same spring rate as mine or would they be a little stiffer? Sounding hopeful :)

They were uprated springs for my 916, they cured Matt's slipping Clutch problem
