This weekend, my buddy with an S2000 was at an event and I was checking out the wear on his RT660's. He's mainly used them for autocross as a dual driver car and some street use. He's done 5 events with our main region, then another one 3 hours away (which he drove them there on), and 3 at another local region. Double those figures due to it being dual driven. He has somewhere around 10 events, 2 drivers, virtually 18 events(subtracted two his co-driver didn't come) if it was a single driver car. This would be about 110 runs.



He drives them hard and is experienced. They're wearing really well. Gets solid times on pair with my DS setup BRZ... in fact he's been a hair ahead the last few events with me on Yoks.


In comparison, he was shocked when he saw my Yoks were toasted 14 events (single driven), 94 cumulative runs. I'm impressed with how they're holding up, yet netting him great times and are cheaper than the Yoks. I think he'll get the next 10 events out of them or another 100 runs... bringing them up to about 200 runs total. That's insane.


I've taken RE-71R's out to 200 runs... twice. They heat cycle out after 125 runs being competitive, and really drop off at 150 runs. We'll see if the RT660's do that being about the same weight as a BRZ and RWD in his S2000.


I'll likely go with the 660's next time or even later this season if my Yoks die off. I haven't been impressed with them. They're good in the early stages of the season when new and when it was cold... however for summer and nearly 100 runs only, they're getting noticeably slower IMO. It's hard to spend 25% more and get probably half the life and be compromised half of the season on hot event days. It was worth the experiment though.


The Yoks would be good for a -4 degree camber setup car and doing <15 autocross events per year.... if you if only want a tire on a second set for spring/fall cool events. The RT660 is right up there with the RE with all the general characteristics of them which will get you through a year of racing (20 events) without flipping them and be able to take a range of temperatures... and even a track day or two probably.
