This is probably the best tire for the Subaru Impreza STI, it gives very good feedback, has excellent grip in the dry and good grip in the wet, greasy surfaces are a little interesting but the car does slide predicably.
These tires like heat, put them out in snow and your going to hit something, they are a summer tire only, not keen on sub zero temps so I would suggest a set of winter tires in the colder seasons.
Solid sidewalls give excellent feedback but have a compromise with increased road noise and some tramlining (though newer sets seem better than the originals)
Excellent all round tire.

For me the best tire I've ever had or seen. I don't care of road noise (anyhow it's not that high), I don't care of high wear..., this is the perfect choice for my Subaru Impreza WRX. Dry grip and temperature stability is a miracle, wet grip is very fine concerning the tread design. Okay, noisy, very stiff, fast wearing..., but definitelly I've never seen/owned a better tire for my needs. Had Nokian Z, Potenza 050a, Yokohama s-drive, Dunlop SP3000, Firestone SZ80, Toyo Proxes, Falken 452 before..., but realy none of these can be even compared to RE070 - it's just completelly different class of tire.

Not a good choice for road sidewalls are too stiff and they tend to tramline especially as they wear.

However on track when warmed through the tires are superb, when R888 are running hot these tires just go on and on and offer great feedback

My drive is a Honda Civic type R(japan version)
the tire come with stock, it did so marvellous in dry and also when attacking the corner with high speed... done so well in grip!!
but unfortunately it was too hardcore and uncomfortable for daily use.
