A tire that can do autocross and track days.
the 71RS warms up fairly quick and has good grip, more temp has a small drop off in grip, but it levels off.
Means you have 1-2 flyer track laps then times will drop 1 second or so.
but it levels off and you can PSH hard without any lap time increases.
track days do increase the tire's hardness, and that makes warming up for autocross harder.
the RS71RS at 75F sitting are about 55 on the durometer
after 113 autocross laps and 15x 20min track secessions, the durometer at 75F is about 70.
A BIG increase in hardness. at that point it's a track only tire or you need LOTS of temp to get any grip back.
113 autocross laps and 15x 20min track secessions and not corded yet, a durable tire.
-3.5 camber +6.0 caster Zero toe on a 1992 Camaro.
Rear end is a Solid axle
wet grip is bad unless you can get the tire warm
the A052 will still win out in low temps and rain conductions
the RE71RS tend to work better on heavier cars, 3,000lbs+
The lightweight cars like Miata 's tend to favor the A052
