Oh, we are switching as well for the next race. I don't have any feedback on them but anotehr friend who ran an MN12 tbird in Lemons recommended the Nitto NT05s in 255/40R17s.
I bought them from Discount Tire via eBay and got a pretty good price comparable to what we were paying for 15" Star Specs ($133/ea). You just have to wait for one of their deals.

I used GCs you can buy for 10-15% off from SamsungPay during their promo periods, eBates/MrRebates portal, and eBay Cash to bring the price down further (down to $120/ea IIRC).
America's Tire/Discount Tire retail shops will also mount them for $19/ea (compared to Tire Rack Tires which for me in the Bay Area I can get mounted at wheel works for $15/ea).
At that price, it was worth trying them.
