i know that there are 13 lb and 15-16 lb stock fd rims. how do i tell the difference? besides weighing them of course?

They all weight the same And even if they werent aren't scales the most common way to distinguish weight.... https://www.nopistons.com/forums/pub...DIR#>/wink.png

yes they are all the same weight, however the earlier ones are prone to cracking

actually the VERY early wheels were a 1lb or 2lb lighter... on the back of the wheel the casting is very hollow.. thats how you tell.. They are however prone to cracking.

If so then I stand corrected. - https://www.nopistons.com/forums/pub...DIR#>/cool.png
