Thanks Harry,
As always a wealth of good,carefully considered sound knowledge and info.
I don't like my chances with the Nankang but I am going to try. Spoke with the importers in Auckland and there is nothing in the country so they would have to be specially indented . That in itself would not be a problem but I have to go through a retailer- that is where it could all just get too expensive by the time they put their margins on. At least I a a base line figure to work with thanks to your link to the ones for sale in Aust.
I do have another option that I am considering and that is there are some old stock of a medium compound Silverstone slicks 160/530/13 that fit my rims available from Palmside here in Chch. In theory I should not be using them for classics but heaps of guys do and no one cares apart from the big meetings. They would certainly cover track days and smaller events and at $120 each are now very reasonable buying.
I just feel a touch awkward using them when others are playing by the rules although I must admit I'm getting sick of watching the tread disappear on the R's...
Looks as if its going to have to be a complete rim change to get the 185/60/13's in those rear guards as well, I test fit a Revolution minilight replica and that is giving me 10mm extra inset to play with but its still going to be tight- bloody 4 doors!
Cheers
Dave
