I've heard the Falkens run wide for their size but holy smokes those 315s are meaty! Any comparison shots to the Rivals, Yokos, or stones?
Photo attached with 315 Falken next to 335 BFG, both on 18x12 wheels. A Yokohama 315 on the same wheel is about halfway between these two width wise.
Have guys down the road from me ( Lincoln, Nebraska ) who are good Autocross Friends and they all say the 660 Falkens are a big improvement over the 615, but they are not as quick as the Rival S 1.5, Yokohama A052, or Bridgestone RE71R. Considering that two of these guys are National Champions, the site they and I run is the SCCA Solo Nationals site, that is a fairly credible comparison. But, they also feel the logical next step , since they don't get hot quite as quick as the others, they could be better on a road course? In my experience , talking to racing buddies from around the Country and from some info from Luke Pavlik ( track rat and autocrosser ) at Tire Rack ( ext. #4362 ), there may be some chance this is the case. The A052 is super fast, so is the RE71 and the Rival S 1.5, and the 660 is almost super fast, when viewed in an autocross, but taking in friend's thoughts and listening to Luke, the BFG seems to take longer to get greasy on a road course than the Yoke or B-stones. The Falken seems to be similar ( to the BFGs ) in taking longer to get greasy with guys I know , but the caveat is they are all driving smaller cars.
Hope to hear from our Falken TMO member , but if you go with a 200 TWR tire , I would lean towards the Falken or a BFG Rival 1.5 S. DaveW ( soloperformance.com ) has run BFGs, B-Stones and Yokes on his CAM-C Mustang and not sure if he has hit any road courses, but he might add some thoughts, especially since he is the Clairvoyant that knew the 315 Falkens were already out!!!
Keep in mind, tires that are great on one car may not be advantageous on others ( due to hp, torque, weight, suspensioning, etc. ) and that is part of the reason the more info you get the more you will feel comfortable in your choice. Lastly , driving style also can affect your choice , since some drivers destroy tires rapidly , whereas others seem to get max life out of their rubber donuts, and this is not just an indication of speed or talent. I know some super quick drivers who get one weekend out of a set of Hoosiers, and other speed demons who get 3 weekends and are still as quick - radically different driving style?!
Lastly, listen, listen, listen to others with alot of experience , even if you happen to have extensive track time/autocross time , yourself. Good example was a discussion I had with DaveW of SoloPerformance.com ( and a TMO member above ) awhile back concerning the A052 and the BFG Rival S 1.5s. He mentioned with two drivers the A052s just got too hot during an Autocross event , and he would be switching back to the BFGs. The Yoke might be the ticket for a Miata , but the weight and torque of the Mustang might mean it was not the choice for the bigger car. Another example is the 2nd Place car in B Street at the Nationals, last year , was a Mustang GT 350 on Rivals. The winner was a Tesla, but it was moved subsequently to a faster Class in 2020. The Rivals seem to be a top choice for the CAM-C cars also, as weight and torque/hp determine alot on how quickly a tire gets hot, or too hot.
Lots of ideas from the rambling mind of the Old F.A.R.T. in Nebraska, but I am sure others will chime in and the wonderful thing about TMO is there is a wealth of experience on here ,all willing to assist and help others.
PS - Merry Christmas , everyone!!!
And yet, other fast guys, one who works for Bridgestone, says the RT660 is at least equal to the other top tier tires, if not better. At least on big cars.
No one knows yet, of course. If you look at the Dixie Winter tour results, the 93/193 car was on Falkens and I was (#39) on Saturday. It was VERY cold on Saturday (41 degrees at start and windy) and they were better than BFG would have been in those conditions, but I seriously needed a codriver to make them work. The forecast on Sunday was for similar temps and cloudy, so I switched to my Michelin PS4's and of course it started 5 degrees warmer and got warmer much quicker making it too hot for those. Oh well, I think I improved at least one spot.
Initial impression on the Falken is good, but I need more time, in warmer weather and a chance to play with setup more to see how good. They are not world beaters, but also not slow. They have much better steering response and feedback than BFG or Yokohama, but not RE71 level. Of course, RE71 is discontinued, so it really isn't part of a discussion anyway.
And like you said, it depends on driver, and also event site - Lincoln has some odd properties that other concrete sites don't seem to have. Peru concrete loves the Goodyear SC3 for autocross, but it is not nearly as good elsewhere.
Lots of variables.
