Hi all, Im from the UK and drive a '91 Miata (1.6L). Im not a serious racer like a lot of you seem on here (at least not yet anyway...), but I do like my trackdays and the occasional jaunt round the Nurburgring. I came here because I have a few questions about how to effectively set up my car for fast road/track driving, and would like to hear advice from a more focused forum like this than generic owners clubs.
I havent had my Miata that long, but recently swapped my Rotas for some Sportmax 002 wheels, 15x8j ET0, on Yokohama A539 tyres (195/50/15). Obviously theyre not ideal track wheels, but then this is my daily driver, and theyre only 0.5lbs per wheel heavier than the Rotas.
Im planning on having the wheels/suspension aligned soon: -2.75 camber (front & rear) 1/16 toe out (front) 1/32 toe in (rear)
Will this be OK? Im looking for a good amount of grip...
Also, my next concern is to do with my tyres. Obviously being 195/50s, theyre stretched a little to fit over the 8" rim. Is this safe? Heres a pic:
Im thinking once the weather gets warmer of switching to Toyo R888s. What size would you guys opt for?
Thanks for any help, it will be much appreciated. Eventually Im hoping to swap an SR20DET under the bonnet and start taking racing more seriously, trying to get sponsored and enter the Time Attack series over here. All a pipe-dream at the moment unfortunately.

Most likely the SM tire will do the best as a bigger tire will slow the car on the straights. We have done testing for ITS with bigger tires and found that the SM size tires were faster.
