I have Fuzions, I just posted a review of how they've been doing. They are pretty close to as sticky as real auto-x tires. And I know how to keep from understeering, I just have trouble doing it! It's not the understeer that is the problem, it's that I'd rather have a drift as my failure mode. It's faster and easier to control. Plus, understeer is just not fun. And it's slow. Getting more traction up front is going to be a huge deal for me, I need it!
