SVTF in H Stock.

[Reza]

Since I am done with my school, I am thinking about getting a stock SVT for next year H stock.

This is what I have in mind.

1. Stock SVTF with no options.
2. Koni Yellow.
3. Crash bolts for fronts.
4. 17x7 TD PR 1.2 E+45.
5. 215/40/17 V710 or 225/40/17 Hoosiers.

what you think it should be a very good car for H stock.

or I can go the other way and built a 2.3D for FSP but its going to be a lot more expensive.

Where is the 2.3 classed? Seems to me a base d23 car would be a better stock class contender than the SVT

[Reza]

my main concern is wheels

SVT has 17x7
2.3D has 15x6

SVT has better suspension as all also.

I'd like to see it done.... my biggest concern is gearing.

The bummer though is I've never found any paperwork to make crash bolts legal in stock.

I've driven a G-stock SVTF at a National Tour with V700s (when they were still common) and Koni Yellows, and it just didn't feel as agile or quick as my H Stock 2.0L Zetec.... BUT, it wasn't the ideal options setup.

You'd need one with NO sunroof and definitely no damn winter package. That traction control is just crap.

When did SVTs get moved out of GS?

2010 I thought... though should have done it for 2009.

...or I'm confused, but I do know they're moving.

yeah but even with 215/40/17 for svt and 205/50/15 for the 2.3 the svt has better gearing.

do you know how much camber the stock svt has with no crash bolts.

yeah I know thats why I said no options.

2010 I thought... though should have done it for 2009.

yeah that why I said next year. I have enough time to set the car up for next season.

[Mr. Blue]

The SVT might have better gearing but the 2.3 had the torque to deal with the gearing issue. I think that might be where his concern came in.

[OmniFocus]

Yep... the 2.3L comes out of the corner with all sorts of wheelspin, even with tall 3.42 gears. The SVT comes with bog-o-mania.

...which might actually be a good thing.

Reza has an advantage dealing with the SVT though, since he ran one in STS for so long.

I've been considering the switch to HS next year also. I don't have the ideal setup since I have the sunroof, mach headlights, and audiophile sub. I'm not too worried about being nationally competitive yet since my driving has lots of room for improvement. I have been looking into similar parts. I found some new Tokico shocks that I've never seen before. Anyone know anything about them?

[TennTechMan]

Oh, and why not 245/40/17 tires? One of our local guys runs 245/??/16 tires on the front of his HS Mazda 3.

[sleeperlove]

^^ Thats a (edit: not as big as I thought but still tall) tire. It will kill the already not that great gearing of the focus.

[brads03zx3]

Because a 245 won't be at all advantageous on a 7" wheel.

[TennTechMan]

I've seen a nationally competitive BS RX-8 running 285 tires on a 8" wide wheel. 245's on a 7" wheel isn't as extreme as that. TireRack recommends that tire for a 7"-8.5" wheel. I'll probably give it a shot if I go to HS.

[sleeperlove]

GRM just did a tire test of properly sized tire vs FAT tire same course, same car, same wheels. The properly sized tire was faster and produced more lateral G than the fat tire pinched.

It was on an Rx8 I believe. They did 255 vs 285

[thefrush]

More contact patch on a properly sized tire than an oversized one. Less sidewall flex.

Same kind of test done by Road and Track with a Mazda MX-5. Interesting results:

Thats not the same kind of test at all. In the GRM test they used 255/35/18 Hoosier A6 and 285/35/18 Hoosier A6.

[brads03zx3]

I can tell you I've tried to run a 235/40 NT01 on a 7.5" wheel and it was not as good as the 225/45 I am currently running. Not a very scientific test, but the contact patch was smaller, response was more sluggish, it was a pain in the ass to fit (allowing less alignment adjustment for optimization), and even the 225 is pinched. I'm a fan of properly sized tires.

ok, ok, maybe not the same but still good info

New around here and digging this one up again. We just purchased and 03 SVT this year and my wife has been using it as her AutoX/DE car. With the SVT moving to HS next year, she wants to get some R-compounds for next season (been running Dunlop Star Specs this year in our clubs Tire class). In terms of the tires lasting, I'm thinking with the lack of camber that the Hoosier A6's aren't a good option, and the V710's in the 225/17 sizes are the squared shoulder tires that don't like camber challenged cars are a bad idea as well. That pretty much leaves Kumho Victoracers. Does anyone have any experience running the A6's or V710's on a stock SVT? How is the wear? Also, with stock suspension and rims, will a 225/40 or 225/45/17 rub?

[brads03zx3]

The A6 or V710 would be your best bet if you are trying to be competitive. The victoracer would be a good tire if you are trying to save some money. No, they will not wear all that great, but if you rotate your tires every event, and probably flip the tires every few events, you should be able to get them to the cords. A big front sway bar will also help with the camber issue. Those tire sizes should fit without rub. There are a couple different theories out for tire sizes though. A 225/40 would definitely not be the ideal size on the stock 7" wheel, but it would be wide and short. A shorter sidewall is going to be more camber sensative, and a tall sidewall is going to hurt that tall 1st gear on the getrag.

I've run all the tires on other cars, so I'm familiar with them from a performance standpoint, just was curious about the wear issues. She is a very smooth consistent driver, but still has to work on squeezing 10/10ths out of the car, so I don't think she is quite at the level where she is going to notice the extra grip of the A6's/V710's over the Victoracers. I am going to be putting the H&R 24mm bar on the front end in the off season, so as you mentioned, hopefully that will help some too. Rubbing was my other concern, so I'm glad to hear those should work with no issues.

Do it! Sounds fun! 215/40's

Wheel size in the Sport of Autocross is important! If you want to do the 'hip-hop' thing and go to a car show then those 17 in wheel may be suited correctly, but if you want to enter competition do your homework on wheel size. Start with 14 or 15 inch. 13 inch would be ideal, but classification would have to enter into your problem area.
