I started with 185/60 Star Specs on stock 14s for Autocross, Circuitcross, and Hyperdrives. Never really had any complaints except for the tall sidewalls.
This season I've been running 225/45 Toyo Proxes R888s on 15×8 Konig FlatOuts. They have been pretty awesome in Autocross (3/3 class wins so far) and HPDEs. I got another set of Konig 15×8s that have a set of shaved 225/45 Toyo Proxes RA1s. I'm curious how they are going to stack up compared to the R888s.

About to put 275/40/17's on all four corners of the RX7. After puncturing an R6 in a turn at a hill climb event and nearly putting it into the face of a cliff, I've decided I need a more substantial tire and am going with NT01's this time around.

I have used 225 NT01's, 245/580 R80 Hoosiers and 245/580 R100 Hoosiers.
The R80's were over the top with grip. They came up to temp pretty quick for a slick. They corded after 12 heat cycles. Never flipped or rotated em.
I am trying the R100's based on experiences of a friend. He ran R6's for years but for the last 2 years has been running R100's. He claims better grip, much longer life over the R6's and more consistent grip over the heat cycles. After 4 heat cycles I was surprised to find the R100's had similar grip to the R80's. They did take longer to come up to temp though.

You can run non-dot tires in your class. Have you considered Avons? From what I've seen, the early adopters of them in the auto-x world are going seconds faster than they used to on cantelievers/A6s/Radial non-dot. Of course adoptions is slow there because the non-dot classes are mostly filled with old people that dont like change.
I get the Hoosiers at cost through a friend who is a dealer. Between that and the ability to win some contingency tires I will stick with the Hoosiers for now.

I recently installed a set of BF Goodrich Rivals (205/50/15) and ran them last week at Road Atlanta. I was impressed. Not a lot of noise at the limit but very progressive and smooth slip that was easy to control. They are not Hoosiers but a great tire you can drive to the track and run.

$/run (competitive), Avons are actually cheaper than A6's for AutoX.
Many say A6's fall off at 40-50 runs, I enjoy them to 60 runs, after that I'm just giving up more than I'd like.
Avons on the other hand are competitive in AutoX untill they cord (about 100 runs). They are also about 1-2 second faster than A6's per the XP Nat Champs I've spoken with. These will be my next tire purchase.
PS. I've run Hoosier race slicks, R75 compound, but they fell off a cliff at 40-50 runs, after that they were way slower than my 110 run A6's.

I am currently running 15x7 Good-Year eagle slicks 23x9.0 sports car special R475. They have 6 track days. Amazing grip and so far good wear on 2000lbs all motor current car. Unsure what direction I will go next. Prob 15x9 next and very undecided on tires.

I switched to Dunlop Direzza 03g (205x50x15) from Toyo TR1's (195x50x15) both on 7" rims.
As expected the car was approx 3+ seconds quicker. I was very surprised with the Toyo's, they handled track work very well, the rubber was working well (visually) and as a road/track tyre I thought they were great.
The Dunlop Direzza's are simply amazing, Whilst I don't have a lot of car experience yet I find them VERY grippy, reasonably long lasting (equal to my friends R888 from what I can tell) and very predictable. My last track day i had a series of S bends where i was consistanly 4 wheel drifting from apex to apex (bravery courtesy of years of R Factor!) and was very surprised and thrilled to find my quite experienced passenger say he thought we were a goner at least 2 times per lap when I felt we were well under control...one of us was right, at this point I'm going to go with me becasue we didn't spin or go off track once...yet
.
Anyway reason for the post is next weekend I will be on my new set of 15x9 6UL's and 225x45x15 Nitto NT01's.
I have no idea what to expect and look forward to posting after the weekend the comparison of the Dunlop to the Nitto's.
Bare in mind our compounds are sometimes different to yours in the states, for example the R888 is a very well regarded tyre here BUT I believe we get a different compound to you guys.....which reminds me, I have a setup question in terms of alignments for the new, wider tyre...will start a new thread though.

Hankook Z214 225/50-14 on stock 14x6 wheels in C71 soft compound on a stock '99 for CS autocross. $628 a set vs. $944 for Hoosier A6s, and as far as I can tell, they stick pretty well and wear like iron. I have about 40 runs on mine, and they're not ready to flip yet.
If I drive decently, I can usually outrun all but the fastest people in the local club (Chevy Luv with racing slicks and a SBC motor, heavily modified STI with a wizard at the wheel, new Boss 302 when he's on the sticky tires, S2000 on A6s, sometimes the guy with the supercharged 3-series) , and I don't aspire to anything beyond that. I always beat the guy in the NC on A048s.
They will get slimy on longer runs (over 80 seconds or so) or if I let them slide too much. Maybe don't handle temperature variations as well as the Hoosiers.
As an aside, I'm sorry to see R-comps getting kicked out of stock class, a set of the 'Kooks is pretty reasonable and it saves tearing up the DD tires.

I've run Dunlop slicks for a while now (220/565/R15). We are limited to 8" rims in my current class. My car is around 2100lbs wet and has about 170whp.
They are a great tire. Soft in the sidewall though, which takes some getting used to. They seem to need a lot of camber on an 8" rim to work. I think the 220s would be fantastic on a 9" rim, and I plan to try that in another class when my new 9" Konigs finally arrive. They do drop off after 7-12 heat cycles (depending on how hard you drive them), but you can bring them back somewhat with decent tire dope (legal here - I use Octopus Grip). Damn expensive though so I've started to look at other options.
I recently did an enduro in the same car on 205/50/15 NT01s (again on 8" rims). Decent tire, consistent over the race distance (around 220 miles), but obviously a lot slower than the slicks (around 2.5 secs).
I've also tried the Kumho s700 slick in 200/580R15. They are a lot cheaper here than the Dunlops, and around 1 sec slower, but they seem to last better and are also responsive to doping. Much stiffer in the sidewall so they are more responsive, though that probably has a lot to do with the 200 width on the 8" rim compared to the 220.
I have ordered a set of 215 Hoosiers and another set of 245s, both in R100, but they are on the slow boat to Australia and won't be here for a few months. I'll try the 215s on the 8" rims as a point of comparison. I also have a set of 10" 6uls ready for the 245s and am very interested to see how they perform.
Kiwi, how did you find the NT01s?
On another note, everyone here in Australia is raving about the Yokohama Advan A050 R Comp tyre. There are guys here doing similar times to slicks on this thing and they seem to last forever, but are really pricey. Surprised they don't get much of a mention here, are the available in the states? I also have a set of those (in 225/50/15) ready to go on the 9" rims when they arrive.
