Got big hp? But why?

Mazx6,
Your going to be limited with your setup... @ +22. If you want to run a 10.5" rim, it's got to be +28 or higher, that is if you want to run wide rubber and still come out flush with the fenders.
I'm running 10.5" rims @+29 on 295/35/19s and they protruded when I was stock height. I then dropped it on RS*Rs 5/8", had to trim the fenders, and now the tire sidewall is dead flush with the fender. I believe there is a guy running 11.5" rims, but his offsets like +43 and he's slammed.
If your looking for a wide tire at an economical price I would look to the Conti 2s (295/30/19), at 25.9" dia. and 12.2" wide. You'll see them on 911 turbos most often. They're usually around $305 with a 100Y speed rating. As an example, the PS2s @ 305/30/19 w/102Y rating will run you around $450... huge difference.

The conti2s will most likely be my next tire, just for looks...
For FI guys, maybe running a 295/35/19 isn't a bad idea, considering the tire dia is 27". Should be able to hit 60 in second gear with no problem.

The tires are potensa s03s. I've got no traction as it is. I am friends with a few other fi z owners in the chicago area who claim to have the same problems. So I guess my question is why are you guys building your motors and racing to 700whp what's the point of getting there? I couldn't imagine anything over say 525 even being controllable. Am I missing the boat here is there some big traction secret I am missing? Obviously I could upgrade my suspension but is that really gonna make a difference? Or are you guys just going for bragging rights?

I think this is a very good question or at least the other question it poses... How do I use all that HP/TQ? I have the APS ST and it breaks out all the time (which can be fun) but at some point safety and driveabiltiy become an issue.
I, like most when they go FI, already have better springs and sway bars. So besides bigger, sticker tires what else can make a drastic difference in traction for everyday driving?

Charles, the tire I have now is the 305/30/19 Michelin PS2. It looks freaken HUGE! Just waiting on the wheel to mount it to.
Beastie, start with the largest tire you can tuck under your rear fender. Then look at upgrading your suspension, softening that sway bar, and installing an aftermarket LSD, such as the ATS Carbon LSD (my favorite). All of these thing will help. You will be surprised at just how well you can hook up on street tires, from about 45mph onwards....even with insane amounts of trq and power.

Over 500whp you may have more issues but if you are under that and have traction issues do the following it drastically helps. Next up for me is a 3.3FD and a 255fr and a 295Rear or 305 if I can find one. Prepping for my power increase.
1. Get a stickier Tire PS2, RE050 A, KDW, SO3 whatever something sticky and
285 or larger
2. Correct your camber
3. Put your sways to Medium
4. Get an adjustable coilover setup and set the rear to soft.
If you can afford to do all then obviously correct your camber last. I still have some traction issues, especially when cold out or when the tires are cold but Im telling you, I have the Zeal V6. They are 6 way adjustable. I put the front on 3 and the rear on 1 and I cant get the rear loose in 3rd and barely on the top of 2nd. If they are stiff I sometimes get loose in 4th when its cold out and I haven't warmed the tires up.

Hmm thats interesting a 3.0 FD. I don't know how that would work but it could be a good thing. What I do know about the 3.3 is this. You can do 62 in 2nd where as you'd have to shift to 3rd to get there. Stay in 4th in the 1/4 mile. Do 80 in 6th at 22 or 2500rpms vs 3k. Now with a built motor and a 71 or 7200rpm limit and a 3.3FD you can probably do close to 70 in 2nd with good traction. Imagine your 1/4mile then.

Thanks for the suggestions! I have no idea a 3.3 would do that. I thought you would be at a higher rpm @ 80mph. Does that mean you would improve both your 1/4 mile times and your mpg on the highway?
Also, I did a search on your Zeal V6. They seem to be a VERY nice setup.

I would say where it is now, a 3.5 but the power is too snappy at 9.5psi so either a smoother torque curve or less power.
Your MPG should improve cuz lower engine speed and your 1/4mile should improve because you'll get better traction, longer gears so you use your power band more and less shifting. The Zeal are really nice but its not perfect. They make a squeaky/squishy noise from time to time and i wish the adjustment was electronic and not manual. Other than that only more adjustability would be nice. Its still my preferred choice.
Correct, im running my 245/35/19 PS2's with my 285/35/19 Bridgeston Reo50A's. There is no problem so far, such as VDC or because of using different tires. The PS2's do grip better but the Reo50A's are pretty close.

3.3FD
OR
3.9FD.........with a twin turbo of course
