FYI I have just submitted a group tire order to Ruth at Gee & Gee Racing in Leduc.
For WCMA racers outside of the Spec Miata class who are using the same tire, I believe the price is $247 a tire this year. Its still a great deal considering the USD exchange rate lately.
Give Ruth a call at (780) 986-7223 if you need some.
