well the guy says that he cant do it without the crank and to balance both its £150 is that expensive?
Utter crap.
Flywheels and cranks are balanced independantly from the factory...you can buy either individually from VW.
You only need the flywheel done if you aren't planning on going much over 7500 RPM.
I have a standard bottom end, and lightened flywheel, and it'll spin at 7600 all day, perfectly happily.
Join Club GTI, and use Hotgolf...he's the man.
Is yours a 8v or 16v?
I have a spare lightened and balanced 16v (O2A) flywheel sat in my garage doing nothing.
