Anyone have these, know anyone who has them, or know anything about them outside of the usual marketing tripe that retailers have on their sites?

I'm strongly considering getting a set to try out on my Subaru, and if I like 'em...a set might make its way onto the FD.

Any thoughts?

i got a friend thats got'em on a 92' vett, says they are great stuff and he loves them. Hes road raced with them too and they do great. Grassroots motorsport has done a tire review this month and they like this tire too.

Awesome. I've been contemplating a purchase of these tires as well. I run the 712's now which are "ok" given my current hp level. I'll need something a bit more agressive in the not too distant future due to a single turbo upgrade however. Which month are we referring to (Grassroots)? The tread design is identical to their new roadrace/autocross tire but I suspect the compound is different as is the tread depth.

The same issue (sorry, can't remember what month, but on the newstand today) has a write up on the 712s, and they indicate that the 712's work better when heated up, which jives with what I have heard from street guys before. A good tire for the price is what they say.

I'm thinking about trying out some V700 Ecstas, wonder how streetable they are hehe....

Hmm...just figured out that the MXs are backordered until November at the Tirerack. Might be going with the 712s this time around, or RE730s, not sure which.

p.s. Daniel, did you have Mohammad do any custom IC ducting for you at MZM?

Hehe - no, though he did suggest it. I was holding out for the fg ducts from the Mazdaspeed replica hood guys (Attila and 65imp). Now that I think about it, should have just had M fix me up one, or cobble something together myself - everything went in March... , damn 6 months ago! Oh well, got the bike bug again so getting the 7 finished slipped a little further back on the priority list...

The 712s are fine for regular street use, and seems there are more then a few people using them as an affordable auot-x tire too, with good results. A bit on the heavy side though. Had two sets myself, though barely got into the 2nd set when I sold the wheel/tire combo. Thinking of the fun you can have using to the excuse of heating them up hehe.

enuttage

Cool. I'll probably go for the 712s then. My WRX is a pig anyway, so a little extra weight isn't gonna hurt much. And I do autoX quite a bit (though more and more with the FD).

Speaking of which, that's why I asked about the ducting. I *must* get a new radiator, new oil cooler(s) and the ducting done. The car can't handle repeated runs in the summer at the autoX right now. I'm overheating pretty nice. Road use is fine at least.

Thx D.,

Have you seen the Yokohama AVS ES100s yet? Very nicely priced, though I have not heard how well they work yet:

I have not really driven the 7 around since March, except for the occasional night workout.
Really need that IC duct badly, as that the air temp goes up to 59-62 degrees and just stays there (at night). Any day now, though...

oh, btw, hes running high 12 second passes with these tries, too.

Guys, I had 712's on my FD a while back and I absolutely hated them. No stick. Granted they were hard to kill (I tried hard because I hated them) but I replaced them before they were half worn as I disliked them so much. They feel fine, but have little grip. They are good in the rain though.

enuttage

Hmmm...everything I've read, reads contrary to this. Granted, if you're running S-03s, or KDWs or something the like, then you're running at least one price class up, if not several.

Most of what I've read about the 712s has been very good, including good stick and great sidewall strength. Tirerack's customers rate the stick as "Excellent", halfway to "Superior".

But...you're in Dallas, so I'm definitely noting that you're running in similar conditions to me on the street and you didn't like 'em.

Thanks for the input (scratches head in newfound confusion).

The November issue of Grassroots Motorsports has two tire shootout tests: one for R-compound tires and one for street tires (the ones that Tire Rack would call "Max Performance" tires).

They couldn't get the Ecsta MXs in time for the full street tire test, but in a test they conducted later, they seem to like them pretty well.

DamonB

I agree with your logic; you need to stay at the same price point to compare. Nothing against Kumho; I run Victoracers at the track. I have had old Dunlop D40s, Dunlop SP5000s and right now I have Continental Contact Sports I got for less than $100 apiece from Tire Rack. All of these have more grip than the 712. The 712 feels nice and gives good driver confidence, but its ultimate grip is very lacking. Hate is a strong word for me to use, and I hated them.

IMO, the 712s are just "ok" at best. so far best bang for the buck are the Falken AZenis. i have these on my Subaru and i love them. they are VERY sticky although a little loud. i am highly interested in these MX though. my friend has Parada Spec 2s on his 89 M3 and they are pretty good as well but a little high in price. i currently have AVS Intermediates on my RX7 but will probably switch to the MX next spring. unfortunately i dont have experience w/ R-compounds or any of the higher spec sticky street tires(S02s, A053s,KDWs) so i dont know how these tires compare to the higher spec ones.

Sit right back and I'll tell a tale, a tale of a faithful trip....

Or something like that.

My old man flew one way from NJ down to GA to buy an R1. The tires were shot, and he needed new ones for the trip north. He got the Kumha Ecsta 712s in V speed rating. Not Z, so it's not 100% relevant, but.....I yelled at him for getting them. You don't put tires like that on an FD. The *last* place you skimp is tires. I just blew 800 bucks that I couldn't afford on a set of Bstone Potenza s03 pp's in 245/40 and 265/40/17s for my Fikses and felt good doing it.

Initially my pops was like "Hey, they're not bad at all, son. You're full of ****." 3000 miles later, he was like "Wow, these tires suck. Adhesion at the limit is nonexistent. Time to get rid of 'em."

Look into the Yoko AVS Intermediates--the tire rack is practically giving them away.

enuttage

Well, after getting a *little* more input from VW Vortex, a BMW forum and a coupla other places 'round the Web, I'm definitely going with the MXs. This'll be on the Subaru first, but if they prove worthy, I'm wrapping the FD with 'em.

Rich, too bad your dad had a bad experience. My bro-in-law had the 712 Zs and got over 10K out of 'em with hard driving and autoX time. Either the Vs really suck, or your dad is WOT all the time.

Anyway, once I get 'em mounted I'll post a review. Different car, but still relevant IMO.

Last minute experiences with the tire are appreciated at this point.

712s probably make great drifting tires.

The Victoracer V700s are road usable (quiet), but stiff riding, and don't last long (duh it's an R-compound tire) Ecsta V700s are about the same grip level, but lighter in weight (this is what I've read from others who've used both the Victoracer V700s and the current Ecsta V700s).

AVS I's are fantastic @$104 each. They're even better at $94 each (255/40-17)...!

Personally, I'd like to try those new Continental Sport Contact 2s and the new Michelin Pilot Sport Cup Comps

Of course as R-compound tires go, Hoosier R3S03s are THE BEST, and I ain't just saying that 'cuz I live in Indiana, either

enuttage

Bump.

Just reviving this thread to see if anyone else has had any real life experiences with the MXs.

The Subaru is sold! So...I have no need for new tires. The new (used) car has brand new rubber on it, so no need yet.

Just doing some research ahead of time...

SleepR1

I've read the MX tires were pretty good, but I'm not aware of any Rx7 owners with the Kumho MXes yet?

enuttage

Just as a follow up to this thread...

I have the MX tires on the Audi now, and I'm quite pleased with the stick and the sidewall stiffness. I'll most likely buy these tires again. Probably for the FD next, as it appears I took a nail to the front right of Toyo at the last autoX event.

Just lettin' anyone who was interested know that the tires are extremely impressive, even with my screwed up suspension on the Audi.

How long do you think these last on an aggressively driven street only car? I'm thinking 6k maybe? A little more?

DamonB

Agressively driven? No way they will do 6K.
