And by 'Watch', I really mean listen. The M4 may be a bit quicker and lighter and the Alfa has a Ferrari-derived engine... but how can you argue with the bark of a twin-turbo AMG V8? Just listen to it! For comparison, especially since Sport Auto tend to be a bit slower than manufacturer tests, the M4 GTS did it in 7:37 when tested by the same Sport Auto driver, Christian Gebhardt. Although to be fair, the M4 GTS is a track-special and was on much stickier Michelin Pilot Sport Cup 2 tires, so it would actually be a lot closer to the AMG with similar tires. The absolutely magnificent 981 Cayman GT4 did it in 7:42 on the same PIlot Sport Cup 2 tires and the same driver. The AMG's time is actually a very respectable time for something that isn't pretending to be a race car. And it's the last old guard in its segment still firing on 8 cylinders.

I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity. Grip is noticeably l
