Falken Azenis RT660 review

“Stock BBS id go with stock size 235/45/17. I did it with RT660+. Handles great and looks great imo. Think I have a 12-15mm spacer. No roll no rub”

“Re71RZ is vastly superior. I got a deal on the RT660+ with some take offs for a 305 square setup for my SS 1LE (6th gen), the sidewall stiffness is not up to snuff for a heavy boat like the Camaro. They aren't any faster than the Goodyear Supercar3 due to the sidewall stiffness issue at least on this platform. I believe they're okay on a lighter car, but I will be switching to RE71RZ when I run these out. They're essentially the same price at this point, pass and go for CRS or RE71RZ”

“Weird wear on Falken Azenis RT660 These only have 2 days of autocross on them and maybe 200 miles of highway. The outside edge of each section is worn all the way down to the wear bars. I was told I could have too much air pressure but Im not sure. These are from the front (275), the rear tires (305) are barely worn at all. On a 2017 Mustang with a recent alignment. Leer más”

“I got a set of rt660s for my autocross setup. From my experience they’re grippy, especially when warmed up. Ive felt like they also lose grip progressively enough to where you have time to correct yourself. I haven’t looked back since I got em.”

Tough to make any hard conclusion given the lack of availability with Yokos and everyone thinking Yokos are the best tire. Most serious efforts bought yokos early and sat on them to run at nats. I don't have any direct experience but will say that the RE71RS is making a good appearance in my locals as well. As far as I can tell, I do not think there's any reason to assume them to be slower than a RT660. They should be faster than a V730. Jury is out on Yoks but people are assuming the stones to be a few tenths off. I love my Yoks but I think the gap between the Falkens and Yoks is overstated as is. Wear and heat tolerance for the Stones are still up in the air too. They're clearly in the running of fastest 200TW as far as I can tell. I think they're supposed to be good in the rain too. All of the finer details, TBD . i think there's a gulf of performance between the rt660 and a052's, easily 1.5-2.5 seconds on track, maybe less at autox, but on a track i've found the rt660's hate trail braking or early power.”

I have V2s ready to replace AR-1s on my C7Z and have high hopes based on what I've been told anecdotally. My exhaust tips are also nicely heat-blued. The valves have an audible and annoying squeak when cycling, but no codes so far. I ran V2s in 315/335 at Lap Attack weekend before last and was expecting to pick up a second from 1:18 previous best on V1s in 285/315 on half inch wider rims though surprisingly didn’t and ran the same basic time as 315 square RT660s. Figured the extra width and “better” compound would show clear gains, so am a little disappointed honestly.”
