Default HPDE + Auto-X + Street: Rt615 vs Z212 (again)

I know this comes up, but I really searched and didn't find any threads that seemed to answer a few of the questions I have on both of these tires. If I missed it, please let me know and I'll go read with my tail between my legs.

My intention is to only have one set of wheels in the long term, as after running the numbers it would take about five years of re-mounting tires to pay for the second set of wheels. Right now, we have a set of 17x7.5 Prodrive GC-07's that I don't see us parting with any time in the near future, so tires need to fit on those. We (my wife and I both) are hobbiest auto-xers (don't take it too seriously, but have a good time and are sometimes even competetive) and are starting to get more into HPDE events. We have Bridgestone 950 (I -think-, the car is at home right now) on there now, and the last HPDE chunked them pretty bad. So, we're in the market for a new set as the seasons start approaching and I think I've narrowed it down to the Hankook Ventus Rs2 Z212 and the Falken Azenis Rt615.

The WRX is our second car, so it doesn't get out much and thus winter isn't something I'm that worried about. However rain is definately an issue. I would also like to go 235/40, but the 615's aren't available in that size. But I understand they may be wider than other 225's, so we could go 225/45 for the 615's.

Ok, all that said, it was my understanding that the previous gen Azenis got greasy pretty quick, which seems like they would be a handful on the track. Are the 615's the same way? I've seen a few posts about the z212s on the track that seem favorable, so I'm leaning that direction. However, I thought I'd ask if there were any opinions of the 615's on the track before I go ahead and purchase.

Thanks!
Mike

212's are $13 cheaper a tire. $50 difference over the total set. The performance is so close that the cheaper tire wins.

Excellent. It does indeed sound like the cheaper tire wins.

Thanks!

I used the hankooks last year for autox. They are great. Good heat tolerance and progressive break away. I'd definitly by them again. Tire rack is stupid for not carring them.

Actually TireRack doesnt carry Hankook because they wanted to buy our tires INCREDIBLY cheap, and you know our tires are sold cheap to the public already so that is one reason why TireRack doesn't sell our tires.
Just know TireRack buys other manuf. tires vvveeerrryy cheap, wish I worked there or was management , haha

Last update I got was that they were going to be available March 27th, if you can with that long. The Falkens are more heat resistant than the older ones, but I'm sure the Kooks are still better in that department. My concern would be with the weight our cars on the softer walls of the Kooks. Though softer than the 215, the 615 is still pretty stiff. So if you prefer the feel of a stiffer tire, the 615 might be your preference. 225 or 235.

I ran a set of z212's last season (got a set -right- when they came out) and did great with them. I honestly like the tires. I put a -bunch- of autox runs on them and they held up very well. They're toast now, but they got me through.

I won my class for the season, and for sure the new tires helped. Of course, coming off of toasted tires, going to new ones will be an improvement 9 out of 10 times...but I feel like I was quicker on top of the 'new tires' effect with the z212's. Grippy!

Now, having said that, I did get a set of RT615's for this season if for no other reason than to 'see what the other side has' now, and they were on sale for not much more than z212's. So, "what the heck", right? I had rt215's in '04, liked 'em, tried the new 'kooks, liked 'em, and now I want to try the new 615's. Thus far, just street driving, I like them. My first event on them is in a couple of weeks.

Definitely not as stiff as 215's, and a bit stiffer than z212's, but that's all 'feel' stuff. People bag on the z212's about the sidewalls, but once you adjust your turn in accordingly, they offer -great- mid-corner grip, IMHO. They're in no way as soft as the average crap-radial, I think sometimes that point gets lost in the translation. People hear "kind of soft" and imagine RE92's Far from it!

I'm too crappy of an autox'er to make 100% qualitative statements about any tire, but I'll hazzard to say pseudo-qualitatively: "they're as good as any other tire for 90% of the drivers likely to drive on them"... meaning.. if you're like me, a typical weekend-warrior not bent on conquering the autox world, then z212's are a great, -affordable- option. Oh, and I'm sure they are capable of conquering the autox world, just not w/me behind the wheel

In conclusion: I concurr with U_S: flip a coin, both tires are good, both are capable of winning.

After your track session with the 615s let us know how they compared with the Hankooks. I'm waiting for the 615s to come up in the 235s but have been considering the Hankooks. I have the Bridgestone RE070's and am used to a stiff sidewall on my wagon. Used to have the Michelin PS2s - nice grippy tire on the street but the sidewall was too soft for the track.
