I run standard settings too on track, sometimes making rebound softer on the rear axle. Interesting that OP is happy with the front being so soft on both compression and rebound. Cool video! |

And nice driving! I hope you are not still actually in the point-by group though... your car control and experience is plenty good for open passing! I was half-expecting you to pass the lot of them on the inside at Riverside

Nice video Ti-Jean! Was hoping you'd dive-bomb them at Sunset, lulz.

Nice. I've been experimenting with left foot braking and doing it only on the street for use later in a select few esses where I need to set the front a little.

http://www.koniracing.com/rrtuningguide.cfm I found that increasing bump in the front makes the car understeer quickly where I could go quite a bit more stiff in the rear. Rebound setting was not as clear to me. I might try a bit stiffer rebound next time but as is (12F/12R), I was happy that day. I think most people with KW CS run the recommended bump setting of 6F/6R but for my car, I can say for sure that 8F/4R worked a lot better and got rid of the understeer at slow to mid speed corner that day.

Left foot braking is a very useful technique. It is something I used regularly on my track VW GTis, even if they were MT. I was taught the technique while doing some dirt road rallying. It brings a whole new dimension to playing with weight distribution and the tire friction circles as you can simultaneously use brake and throttle at the same time. As OC3 said, I find it more difficult to do on the M3 as I only use the standard 3 point harness. If I don't brace myself with my left leg, I tend to move around a lot. I still use it in some corners though, especially long decreasing radius turns.

I ran 2 more track days on the set, and so far *knock on wood*, no issues that I could tell.

Not sure how bad yours look like, but this is the first one on mine (second one is slightly worse). This photo was taken after 1 track day on the tire.

I bought my fourth set of NT-01s last Fall, and the prior three sets going back to 2007 I never had any issues with; however, all four of the latest NT-01s had tread splice failure after about 12 runs at a CCA autox on the Performance Center track (perhaps a total of 15 minutes of use). They were properly heat cycled and driven prior to the track use.
You DO NOT want to drive tires with tread splices opening up like these have at high speeds especially. Contact Nitto and demand service. When I sent pictures of what happened to these tires (and after so little use), they offered to refund me and have Discount Tire send them back for analysis. I bought them in November, and I think the build week was 32.

Yeah, I do believe this is a problem with recently-produced batches. Anyhow, not sure which Nitto office you've been talking to, but the one here in SoCal have been very difficult to deal with (slow, near-complete lack of communications, etc, despite providing photos, proof of purchase, etc). And, after all that, the most I can expect is a store credit based on pro-rated amount of remaining tread depth. You have Nitto contact info I can try?

I was dealing with Steve too. But, rather than "no tread wear," I think Discount Tire being involved in your case is the key here. I bought mine thru a local tuning shop and they certainly don't have the big name nor the volume like Discount Tire has.
