Hi Simon
I just rejoined blatchat for first time in 3 years or so. I also need a set of CR500s to get me through my MOT in May having destroyed my current CR500s at Odiham airfield 2 weeks ago (because I got a puncture in a slick so was forced to use my road tyres).
Anyway the reason for saying all that is I wondered if you were in the same boat, just need to make up a set to get through an MOT, as I may have a couple of serviceable ones out of the set so maybe we could make up a set between us Also I believe you must live very close to me (I'm in Elvetham Heat, Fleet)?
cheers
