Just checked. My fronts have probably 4mm or so left, the left front is a bit worse for wear though, as I said due to crap alignment and some kerbing.
As I hope to change to non RFTs, there might not be much point in renewing these, even though yours are cheap, no doubt.
If you get stuck with them, I'll take one off you to replace my left front, or both if you're really stuck. But I don't want to try and steal them off you.
I'm just in Christchurch so I'll keep an eye here and see how it goes.
