New PB. Fun being no. 27 at Sebring. It is only February and they run 350 hot days per year. That number will drop ? ?
Great job Mark. Strange your variance for your top three is low but your optimal is nearly 2sec faster. Im new to Garmin trying to figure that out, traffic?

These are the rears and are 295/35/18 with 1.9-2 degrees neg camber(oem)
Ahh what rims OEM? What size are you running up front and how did they last? Just about to pull the trigger on a square set of Potenzas for the track.

Not OEM, it's square titan 7 ts5 at 18x10.7. I actually have been running kuhmo v730s 275 or 265 depending up front. Can't really say on those cause my 275s I corded from rubbing the front fender liner due to rockingham speedway having really rough transitions from oval to infield so I only got 5 days out of them and then I had 265 on hand as spare that I put on. Once I'm done with those I'll swap to the re-71rs on fronts for the track.

I do have re-71rs on front and rear for my autocross wheels and they have been just as solid so I would def recommend going for it.

Just know that the RE71RS are really 1 lap wonders like the a052. They hate heat and heat cycle out fast. Traxions experience is unlike anyone else I have seen.

How my track days/years did it take y'all before you stopped lifting at 135-140 on the big straights? Car feels stable, I’m just running out of balls.

Also, did a 1:41 on my 2nd time at Road Atlanta. Decent time for stock other than conti ECF/pads/fluid?

my 71RS have ~3 days on them last season and I'm going to be taking them out for more. Maybe just dont suck at driving?

/s in case the YikesPolice try to yikes me.

Stay flat through 11 and the rest of the track will be a breeze :)

I was running 1:41s there on stock aero and just tires pads and fluid.

You going to make it out to one of our Jzilla events this season?

I hit 158mph/254kph last week which is the fastest I've driven the car, then pulled 1.6G under brakes.
Very happy with the new PB as under 60 seconds has been the goal for a while.

Didn't think it was going to happen as a couple of hours earlier it was 42c and we were chasing a misfire issue that just turned out to be bad fuel.

Maybe 3 to 4 weekends at other tracks then once I finally went to RA it took 1 day but I had put in a few hours on asetto corsa to pick my initial braking zone. Using a sim will really get you comfortable with picking and executing braking zones. Easy one to start with is the motul sign then move it 25ft eventually you’ll creep near the 300 on stock set up. For reference my time I was talking about previously was 1:38.6. At RA with stock everything (even pads) besides wheels/tires my first time and then matched it on the same rears.

Overall yes solid time for a second go, chances are you just need to track out more, use more curb, and execute braking zones.

I’ll admit I’m hard on things, but I’m not a big fan of the RE71RS. The drop in pace in lap one is substantial, even compared to a052 or CR-S. They do slow with heat cycles too, but it’s not dramatic. If you pair fresh and ~10 heat cycled tires on each axle it’s quite noticeable. I see similar life on a052s but less heat cycle death. For either the yok or re71rs I typically get ~20 20min heat cycles before a set of tires is done, so that’s like 3-4 track days. Thats either zero tread or corded done. Most of this is on a different car, similar power, good camber, 600lbs lighter. I’ve have never had RE71r or RE71RS last well for track use. I’ve been through 5 sets vs dozens of yoks. I just took some re71rs with a few dozen autox runs out on stock Supra and the front shoulders look close to done after 5 sessions, I highly doubt they’d make another day. With camber they’d prevent have made a couple more days. YMMobviouslyV
