lol, OK. So, the JE pistons are lighter than everything except the TODA ones.....glad I said that JE 'tend' to be heavy....obviously on the Mk4 they are relatively 'light'..
HKS piston: 362g
TODA piston: 318g
Standard piston: 376g
Standard rod: 771g
HKS 'H' section rod: 594g
Rods are weighed with bolts and small-end bushes fitted. Pistons are weighed without rings or pins. It's also important to note that the TODA pistons aren't really viable for most Mk4's as the compression with them would be around 7:1. Would love to build a mad 2.5 bar monster with them though. I live in hope.
