After the crap service at Tempe Tyres, I headed straight to Australia's Best Tyre. Asked them about the BBS and Simmons and they told me what I wanted to know. Was actually thinking about the Racing Simmons but was worried about finding a tyre that would fit 17" and 6.5 wide, being an odd size.
They then told me that a customer had just driven in a brand new Celica ZZT231, driven straight from the dealer, and exchange the factory 15" 5 twin spoke Alloys with near new 205/55 tyres. I took it off them for $1050 and I wasn't even planning to buy anything that day.
