The Fleva’s are an awesome summer tire with good feel. Great for a daily or weekend sports car, but for overall grip they won’t keep up with the 200TW tires, even the older generation tires like the 615K or the old Rivals. The trade off will be better tread life (probably 30k+ miles on a set).
Gripwise, they are on par with the Indy 500, but having experienced both, I think the Flevas have better ride and steering feedback - all around I think they’re a slightly better tire than the 500’s (which I thought had vague feel and didn’t really like)
With a big turbo setup, you may find them a little lacking compared to the Falkens. Good tire and a minor step up/revision from the S.Drives they replaced but they aren’t really in the same class of tire.
