MY14 bolt upgrade?
 

Hi everyone, I have a 2013 twin and I was doing some research on the SPOON Rigid Collar upgrade and came across this post where Vash said he upgraded some bolts to a MY14 (2014) bolt and it improved the handling of his car.

I've done some searching/googling and haven't been able to find much information on this upgrade.

Who can point me in the right direction? Is the MY14 bolt a cost effective upgrade?

They are actually 2015 bolts, you can read more here:

From reading about them years ago I got the impression they didn't do much but I can't be 100% sure on that.

It also appears the front 4 "updated" bolts had been changed again from:
