Ktr williams uprated engine mounts

[.Stevo.C.]

The engine mounts/gearbox mounts are needing changed on my williams. I bought some second hand ones off ebay but i'm having second thoughts about putting used mounts in. Is it worth buying the KTR uprated ones or new OEM ones and whats the difference between the two?

price mainly. the uprated ones are stiff, but nothing that cant be done yourself with a little bit of tigerseal and common sense
