My guess would be tire rotation, cost effective!
the cost savings will not be amazing taking into account u have spend the time and money to go down to the shop to get it cross rotated.

there are people who go fast on staggered and those who go fast non staggered. The devil is in the details of the setup.
Oh... you could just rotate the tires yourself. Just need a jack and some jack stands. Takes about 20 minutes total to rotate all four and that's being conservative.

I wrote and meant cross rotated.. What you are talking is a front to rear rotation. I have the rear left tyre become the front right tyre and so on which requires dismounting the tyre from the rim. In doing so, you even out the wear.

What wheels are you looking to get? What are the offsets? And what is your price range?

Cross rotating will be overkill for most people. With the 22k miles I have on the current set of tires, I've only rotated front to rear twice and that's where the majority of the wear difference is. Left to right, my wear has been very even. I have to say, I help to even out the wear by doing track days in clockwise and counter clockwise directions evenly. If doing track days in only one direction, you will see more uneven wear side-to-side. Of course, if the tire setup is the standard stagger, there's no option to rotate period.

Why would you take the tire off the wheel to rotate it? I would only do this if you need to flip it because of camber wear. Otherwise just use asymmetric tires that can go either direction or just have your directional tires facing backwards (as long as you don't drive through any standing water)

Im squared and my camber settings for the front is -2 and rear -3 which is slightly off from oem spec but technically if i was to rotate tires, would I need another alignment because of how my front and rear is cambered?

No, you're good. I don't think I understand your train of thought regarding the question.

Yes I do it due to camber wear. I also live in a tropical region where it rains frequently so I'd rather keep to the direction stated.

Rear:

On the rear, I do get more inside wear than outside. On my next alignment, I'm probably going to go back to 1/8" toe-in on the rear as I've been adjusting my suspension setup and it's a little on the tight side. Going back to 1/8" should help with the rear wear a bit. Right now, the insides of the rears are about bald and I have maybe 2mm of tread left on the outside of the tire. It has been about 8k miles or so since I last rotated front to rear, so the front wear is more even across the width of the tire; i.e. still tread left on the insides.

I generally don't agree in the philosophy of adding a thicker front sway bar to regain rear traction bias again, it doesn't makes any sense, it defeats the purpose of adding traction up front to begin with, why not just leave it staggered then.
Why it makes sense: If you add wide tires up front without changing roll stiffness bias, you aren't fully utilizing that added grip up front.

-Why? Adding a thicker sway bar removes weight transfer and ultimately reduces traction, the point of adding more rubber is to increase traction. Too thick a sway bar and you just canceled out the modification.



Sway bars add body control primarily, secondarily can be used to balance traction front to rear among other means in the tool box. Adding more traction up front first and then adding the sway bar makes no sense in this regard.
Of course it makes sense. See above^^^ If you take a car that has good handling balance and add a ton of front grip, you're no longer balanced. Bias roll stiffness to the front a bit and you'll still have more grip up front vs. originally, and also have more rear grip. For me, sway bars are *the* way to balance grip after you've got appropriate camber levels and spring rates.

- I agree, but simply saying run a thicker sway bar as an automatic after adding wider front tires is a misnomer, not always is it appropriate, nore does it offer any conclusion of how much thicker would be appropriate.
So with this, one other problem I see is you can almost always have more room to run more rubber in the rear where the wheels are fixed, unlike the front.
Problem with the S2k is that to go wider than 255 in back, you have to go taller as well, which hurts gearing.

- Not true, the 295/35/17 on the back of my car would state otherwise. These have 20mm added width and the same overall height profile as a 255/40 so no gearing differences.
Also on a rear wheel drive car, your asking more duty from a tire that has to propel the car forward, so almost always having more rubber in the rear is going to create a more balanced car to control. This is my 02.
Honestly, I think people make a LOT more out of handling balance vs tire size than is really in it for a production-based car. In my (admittedly limited) experience, sway bar changes make more significant changes to handling balance than changes in tire width +/-20mm or so. I don't think there's anything magic about "non-staggered". For me, if I'm interested in lap times, I just want to stuff the widest tires I can at both ends of the car given the space limitations and taking into account gearing ramifications. For many/most tracked S2ks, 255 all around is the best solution for maximizing total grip.

- I don’t entirely disagree with that. More rubber first does give you more flexibility to tune your car to its MAX grip potential, whether your using aftermarket sway bars to change the handling and grip bias, or spring rates, or wheel alignment, tire pressure or chassis height etc etc. Knowing how many things can effect available traction to a axel, it’s why I don’t buy into the ‘add front grip, must add thicker sway bar’ philosophy. For one thing, depending on what year S2000 you have, you will have a different weight front and rear sway bar from the get go. 00-01 02-03 04+ all when through bias changes.
255 up front 295 back /thread

Run the appropriate spring rates and settings on your coilovers and chances are good your not going to find any short comings with the sway bars that came on your S.
