The 2012 H Stock Thread

[Phone]

So while Andy Hollis and friends try their luck in STF, I'm going to be autocrossing with my local club this year in my Mazda2 in the TIR class. I already picked up some stock sized wheels and I'm waiting on some money to pick up some Toyo R1Rs and a rear bar.

Have:
2012 Mazda2
15x6 et45 BBS Wheels off of a 1995 M-edition Miata

Getting:
The wheels refurbished
Some 195/50R15 or 195/55R15 tires
A rear bar of some sort
1st place?

Sidenote: does anybody know the weights for the alloy wheel? If not, I'll have an answer within a few weeks.

I will recommend to get the 195-50-15 all around, there is a big difference between the 50's and the 55's different layering of compound..

Not to mention the gearing hit of going to the 55 series tire.

OE wheel/tire combo is 31.4 lbs

What's TIR? Is that a non R compound tire class? If so Id have loved to have that class available.

Around here in northwest ohio if youre not running a hoosier a6 in H stock (or equivalent) you arent in the top 4 in H stock

Weight of that wheel is 12 lbs per:

195/50/15 ftw, also I've had both 50 and 55. (but I don't autocross!)

It's Open Classes, but on street tires. It's basically for those who have done the math and said, "I don't like autocross that much to be paying for $15-30/60 seconds". Good group of folks.

Thanks for the input on the 50 series tires; just need to clean up the BBS wheels, now.

Awesome...wish I had that class...(would have kept my mazda3 hatch then).

You're in luck! Looks like the SCCA is going to try out a Road Tire class. It'll probably be a few years until they nail down the PAX.

In 2 months I start STF with springs which puts me out of HS forever...but...thats not to say I wont autox my next car (probably a 2012+ mustang in a couple years)

I'm running H Stock. Did a couple of event last year in the car, I plan to run full season this time around. I'll be using the car as is for now. I plan to eventually run STF as I wear out factory tires and what not, so I'll be using the car as it came from the factory.

Can't touch rear bar in HS.

 

[Phone]

Yeah you can. It's either front OR rear bar. Not both.

Page 77 of the Feb 24, 2012 rule book.

 

[fam]

was gonna say the same thing but didnt have the 2012 book handy at the time.

Unless you want to waste $$$ on hoosier a6's youre better off running a stock 2 in STF...it has a better index.

I'm just going to run in a TIR class, like I said before. I'm not going to Nationals and I'm not that invested in autocross emotionally to be able to blow 1k on Hoosiers.

I'm using last year's R-S3s that I pulled off of my Miata and just installed the rear bar: this year is going to be a god damn blast.

I managed to get the traction control to fire while merging onto another freeway on a cloverleaf, I guess it's good to know that DSC does do something. :v

BRB, tripodding.

I just ran my first AutoX and felt very competitive with a showroom stock car. The only thing that I want to do right now is upgrade tires and wheels. I am stuck on the decision between running an R comp and a ultra high performance street tire. It seems that most guys are going with the street tire index, but I don't want to mess with all the extra mods so I am leaning towards the r comps. Can anyone/everyone weigh in and share your experience/opinions.

 

[fam]

Street tire index is the way to go. Only upgrades you can do is cat back exhaust...shocks...one sway bar...air filter..mess with camber a little.

 

[pa11cub]

is the dunlop start spec the tire to go with for stf? How about r-comps, what tire is favored.

 

[fam]

hoosier a6 is prefferred r comp.

As for street tires they are all comparable but have different advantages\disadvantages based on what you want in a tire. Read Andy Hollis' street tire faq thread but for lightweight 2's in the dry, the toyo r1r is the shiz..but it doesnt last as long as a re11, kumho xs, dunlop star spec etc
