General Which trackday tyre profile?

[StoneNewt]

I'm seriously thinkin' about getting a set of trackday tyres for the Sei' however the tyres offered at the small end are rather scarce As see it I have two options, 185/60R13 & 165/60R15. Considering these are as close to slicks as legally possible not only will the 185 deliver a marginally higher ratio they'll suck up more power but the 165s will be a harder to find alloys for. So which would you go for any why?

get some avon abc10's, in imperial size but equates to 185-50-13.

otherwise I'd go 175-50-13

Go for a compound that you like, then match the size. I would stick with 13's and go Yokohama 048R 175/50, or 032R Super soft in 175/60.
