Need Autox tire recommendation: Hancook RS3 V2 vs. Direzza Z2 star spec

Thanks

Right now, I think the RE71R is the no-brainer best tire. There's a lot of talk still about the Rival S that is supposedly shipping in April, but we don't have any testing numbers, mostly just hearsay from a few people that got to run on them after nationals last year. Since all 4 of the national events that we're running in the STU car are in March and April, it was an easy decision for us. We'll probably have another decision to make come nationals, but we'll be able to see what people think of the Rival S before we do.

On the wear issue, I think there's no doubt that they're going to wear a bit faster than RS3s, but I don't think it's much worse on our ST car with LOTs of camber. However, on my stock 370, I'd definitely be on an aggressive rotate/flip schedule to maximize their life. I'd probably aim to have a "fresh" outside shoulder mounted on the fronts for every other event.

The OSGiken Vette guys posted a picture of a 285 RS3 next to a 275 RE71R, both mounted on 10.5" wheels. The BS is only slightly skinnier, and I think you'll find that the extra grip is more than worth it.
