So update,
Everyone I have spoken with about this is very please with the work Stuart has done,
I have gone for the F160 package, ultralight flywheel and clutch, wrapped primary pipes, decat pipe, dual oil temperature and pressure gauge.
While the cars with them it makes sense to also replace the following
Clutch slave cylinder, water pump and tensioner , oil and filter.
So I will be selling my Caterham lightweight flywheel, 310 cams, Air box with K & N filter, etc etc when my cars done in early May ready for the Taffia run.
