RS3 Version 2 track feedback
Anyone run RS3 Version 2 on track yet? If so, have you run either the first version RS3 or Rivals? How would you compare?
I have seen a decent amount of autocross guys saying they are using them, due to better cold traction, but haven't seen a review from track guys yet.

Ran the RS3 v2 this weekend at road atlanta, I also ran them and the rivals with a AIM Solo DL to record G. the setups where exactly the same for both tires(specs below). both where tested as "stickers". the Rivals held a static .9G with a peak of 1.G. The Rs3 held a static G of 1G. with peaks of 1.2G. The RS3 likes to talk at the limit allot more then the BFG rivals do. the breakaway was far more noticeable on the RS3, as the rivals it was hard to notice where the breakaway point was.
On a neat side note. for the rest of the weekend I switched over to a old pair of rs3 v1 (3 years old mind you) and they were holding a static .9g. They have 50+ heat cycles and are still holding strong. very impressed with the longevity.
all tires where on a 2700lbs LS1 NB1 Miata (with driver),
3.5* camber F, 3*camber R, 0* Toe, 8*caster
225/45r15 tire
6ul 15x9 wheels.
32psi hot.

Yeah, the way you're talking about the R-S3s (note: I have only driven on 2 sets of the 140TW) seems reverse of my experience.
The R-S3s were dead silent when they were getting loose and awful under braking. Sticks like glue in the corners... until it doesn't without warning.
The Rivals like to communicate and are excellent under braking.
I'll 3rd the data for Rivals needing more tire pressure. I ran the R-S3s on a 2300# car on 9" wheels around 31 or 32psi. Rivals get set at 37psi on the same car and wheels.

IMO i didn't like how the rivals took a ton of pressure 36PSI hot and then got greasy after 1 lap. Plus i bought 8 rivals this year, I'm not going back after i had 6 delaminate on me. BFG took all 6 back under warranty, so i would look to them for some street tires. But the rivals were too expensive to replace after every event.

I put about 40-50 sessions through my first set of 205/50/15 rivals. 2/4 of my tires ended up with ever so slight tread splices that were not a problem at all as I kept that in mind with regards to my rotations.
From my pyrometer data, my rivals required far less tire pressure than what you guys are stating to be happy. For me to maintain the characteristically perfect temperature drops inside to out (10-15 degrees per section) I had to be around 32 or so hot. I found that my rivals were particularly happy with different pressures on the front outside vs rear inside. I'm not sure if the ambient temps i run in are hotter or what (90-105 degrees typically with 140 degree track temps).
I realize that this is a rs3 v2 vs thread... but thought i'd add the data point to the mix. I find rivals quite a nice tire and have had zero issues with mine. I'd like to try the rs3 v2 but the braking grip was so bad on the original rs3 that I simply did not find them fun to drive (my car doesn't have abs).

I've had the tread splice too on 3 tires. not an issue so far. braking is waaaaay better than the rs3 v1 as already stated by others. 225/45 on 15x9 and anything under 35psi just doesnt work for me. i don't have pyrometer data, just lap times. I have enough laps at this track that there are no lingering doubts about rivals needing 5psi + than rs3's did.

i'm not trusting a pre cut tire on a 400 hp car lapping daytona at 130mph+. i'm not about living on the edge like that haha.

The data is the data. feel free to do your own test. the pressure is the pressure tested, and that is the results.

BFG took all 6 back under warranty, so i would look to them for some street tires. But the rivals were too expensive to replace after every event.

I was at the same Road Atlanta event last weekend on a set of 225 Rivals (15x8 6UL, 2400lbs weight with driver) and didn't experience too much greasiness. On saturday they would break away pretty suddenly, but they were brand new and seemed to break in and become much more progressive on Sunday. Once I get enough posts to PM, I'd like to hear about those tires delaminating. Mine were also happy with about 32PSI hot.
BFG says not to worry about the tread splice, so I don't. Mine started showing signs early this year or late last year, I forget.

This picture was taken from my race video @ ultimate street car ***. every competitor is required to run a 200qutg tire. 1 session on track, everyone had BFG rivals, including me. it wasn't a leftover from last race, Daytona does an excellent job at cleaning up.
after I saw the thread I became nervous about the cuts and called BFG for a warranty. They took 6 of the 8 tires back under Warranty. So even they thought the tires where dangerous. after that I will absolutely do business again with BFG. the way they took care of the situation was a stand up effort. I'm just not going to run the rival again until they fix the delaminating issue.
