Good point!

He put down some incredible lap times at MRLS with the S2000 that i think will stand for quite some time.

How would you compare the RE-71's to the Dunlops? I am only used to using the Dunlops and was thinking of switching?

Between Dunlop, Michelin SC2's and the RE-71; which would you choose? 100% track for me - zero street driving on my GT4.

Re71r everyday all day. Cheaper, last longer than Dunlop, and equivalent grip.

Thanks for the referral Joe; I appreciate it.

Question - do you find the RE-71 sustains grip fairly well throughout your runs? Or do they grip well and fall off quickly? I've asked a few other drivers (in other platforms) locally about the RE-71. I've heard feedback that they are great for the first 1/3rd of their session but fall off.

Just curious on your observations.

Can you update on what alignment settings you are at presently? I

Lastly - what hot temps are you shooting for?

Thanks,

Chris.

If price is no issue, Dunlops for me. RE71 are nearly as sticky and far less expensive. I also did not have any issues with consistency. PB of every seasion with RE71 was in final laps. Great tire, I won't use anything else for now.

Your feedback may be from people who are over driving the car. Pressures will spike if you are over driving and then you lose grip. If you are driving well, the pressures stay stable.
I've found that the Re71r are the most consistent tire I've ever driven on. Some of my best laps are at the end of a session. If you read this, you'll see that I'm not the only one that has seen this:

I think the cup2 and NT01 are good for about 5 laps before they start to lose some grip. I've only run dunlops once and can't recall.

I've been hitting hot pressures of 33-34.

I agree on the RE71R consistency throughout a session... it's been my experience as well, and that includes quite hot track days in Texas.

Running Dunlops, I found them to be more consistent than the Cup2 and for the traction to last longer through the session, but not as good as the RE71R.

Current alignment:
-3.2F, -2.7R
Zero front toe
4mm total toe in rear
9.5 degrees front caster
Sway bars set on middle front and rear

Tires looking like they might wear even finally

Yargk

Very interesting. What made you go back to middle/middle on the sway bars? Can you tell the difference between 4 mm and 6 mm toe in the rear? Are you getting 500 track miles out of the tires? Finally, how many days do you have on the ME20s now, how's the wear, and how's the feel with the current wear?

(In my experience, with worn cup 2s, the car felt a little lively under braking, but with new RE-71Rs, the car was quite stable on corner entry, I have 3/16s total toe in, =4.76 mm. Also, I'm on middle/middle sways, but I'm going to try middle,hard next.)

DC640

I'm at middle/middle -3.0/-2.2. Zero toe front 6mm toe in rear. Having only 4 days on the track w dunlops, front tire wear is even I do have swift springs upgrade.

orthojoe

After I bumped the camber up even more, the car was starting to oversteer on corner exit, so I went back to the middle settings and that appears to have solved the problem. No difference in corner entry stability or rear end stability under braking with 4mm total toe in. I would have left that alone, but my guy decided to put it at 4mm after he did the alignment and said to try it out.

Mech33

Tarret rear toe links still, right Joe?

orthojoe

Technically, erp, but yes. Did you end up going with tpc? I can't remember

Re: me20

I was able to get 8 days on the me20s, which is 1-2 days more than ds1.11, towards the end the bite wasn't quite as good, but still good enough and felt very similar to ds1.11 at the end, which is still good
