Strange that one group swears by these tires and another says they get greasy. Sounds like a lot more at play here than the tire.

 

The tire can be driven for 1-2 laps and put in NT01 lap times without overdriving the tire (excessive howling, driving through understeer, or oversteering out of corners). But it can only do that for 1-2 laps, then it falls off. I think was in this thread that someone posted about have a conversation with a bridgestone rep who told him that the RE71 reall had a temp range of 110-150*. If you're not getting your tires above 180* on a track, you're not driving the car very hard. After a cool down lap at my last track day, my NT01's had an average temp of 195* across the tire...

 

I guess I haven't noticed the drop off as my lap times both on AX and track tend to remain consistent and even getting a bit faster. This unless I over-drive the car which at my last Evolution driving school I was told that I do (cant disagree with the instructor as I notice it myself sometimes) with an adjustment (i.e. not over-driving) my times got faster and tires remained consistent. With that said, when I do push the car/tires I do notice the tires fall off... I guess then wetting would proce beneficial. These are just my opinions/experience... to each their own I guess. I wonder if camber plays a roll as im -3F and -2R.

 

I love the tires, but they get greasy once they're hot.

The front-heavy Evo is hard on tires, and the problem is worse when class-limited to narrower tires. The Miatas on 245 RE-71Rs and the S2000s on 255 RE-71Rs never have any issues with fall-off here. But the S2000 corner weights are under 700 lbs up front, whereas the Evo front corner weights are around 1000 lbs. Then the Evo fronts have to deal with AWD power as well, while the S2000/Miata fronts are just along for the ride.

For AX in STU, the situation is much better with the 265s than it was with 245s, but I'm still dealing with it.

Our local AX region also tends to do more runs than normal. It's not uncommon for us to have 10-12 runs in a day, so I'm often doing 6 back-to-back runs. Maybe 7 with a rerun in there, but if it gets to that point I usually call it early because the tires won't be up to the task at that point.


If the Rival S ever becomes available in 265/35R18 I'll try a set. My original (non-S) Rival was a decent tire with good heat handling capacity.

 

This is what I was thinking. I'm not sure why I get faster, either. I'd say I have approx 3-4mins between AX laps (we get 5 runs only).
I'm definitely not slow, and if I'm not pushing the tires, then that would make me feel like a stud LOL
I do get some howling and I very rarely push the car into under or over steer. Maybe once or twice while exploring limits on the course.
Maybe I need to push the car harder.
2.8°F, 1.6°R camber.

 

I like the RE71s so far. I prefer it to the ZII and AD07. I have never used RS3's so no point of reference there.

My evo is sub-3K lbs., full Ralliart bushings, front and rear sway bars, and MCS coilovers 10k f/11k r.

 

3-4 mins between runs?! Dayum thats quick! If we are lucky we are at about 20-25 mins between runs. Our events typically have 150+ drivers but we do usually get 6 runs.

 

Yeah, small group. Once you're back to staging, you only have a few mins before you start creeping up, again. Not really time to do much.
It's over pretty quick and only the 5 runs. The cost per min of seat time is horrible compared to HPDE. The only reason I still do it is because I have friends out there and its 10min from my house. LOL

 

If its such a small group, why do you get so few runs?

 

I just looked and they seem to average about 40-50 people per event. They start at 9am (closer to 10am, really), break for lunch for 30mins (turns into about 45ish), then end around 5pm, or so.
It's always been 4-5 runs which is the #1 reason I'm kinda against it. As a non-member, i pay $45 per event. Even at the $30 member price, and considering 46sec lap times, that equals almost $8/min of seat time.
compared to 100mins for $200 at Buttonwillow LOL ($2/min seat time).

 

4-5 runs all day, or 4-5 before lunch, and 4-5 after? In vegas, we usually have 3 run groups, each gets 4-5 runs per "session", and 2 "sessions" per day...

 

You get 4-5 runs, that's it. Morning session is run groups 1 & 2, after lunch is 3 & 4. On the bright side, the session you work is over pretty quick LOL. You work 1, drive two (or vise versa) or work 3, drive 4 (or vise versa).
Just not worth it, IMO. But don't try telling that to the "cool kids" out there. They get really, really defensive when you say anything negative about AX LOL.
It's a horrible value.

Here's the last event. No lunch break, they were done by noon, to avoid the crazy heat. They were in and out in less than 3.5hrs, from what i understand.

Is this a small car club running this? Or this the a regional SCCA club. Just asking because SCCA rules dicktate 5 min between run. I know our SCCA group some times
Have smaller run groups and try to run car through with only 2-3min breaks between runs. A few of us just take our allowed 5 min so we are not hot lapping the **** out of the tires and cars

 

SCCA, yes. They sometimes get 5mins, yeah. Depends on the turnout.

 

I mean whether its 3,4 or 5 mins its still pretty damn quick! With 5 mins between runs you'll def heat up those tires quick!
