Here's the latest testing on the version 2 Sweeps and initial results are positive:

I ran the medium front and soft rears as this seemed to be the best combo for this track. I also let a bunch of the local guys that run pit 571/572 tires test them out.

The finding overall were that the laps times were nearly identical with sweep tires or traditional pit tires with 3 different drivers and 3 different cars. Overall the sweep tires generated more rear traction that pit 571/572 combo but slightly less front traction.

All drivers felt that the tires were good and could do similar lap times with both tires but with Sweep v2 tires the rear of the car felt more locked in. All drivers felt that the balance of the car shifted slightly to the rear when switching from pit to sweep tires.

I also tested the front hard tires and for this particular track the tires were a bit to hard for the temps and grip level. Car would understeer with hard compound tires. The hard tires would be more suited to hot track that has had some sort of surface prep.

The super soft rear tires were a bit to soft for this surface as it is fairly course. This tire would be better for carpet or smooth asphalt surface.

Overall consensus was that the tires had good grip and are great value when compared to pricing of pit 571/572 tires.
