wheel tire combo is same diameter and will drive 0.50% over speed 60.3 @ 60.0

Picked up the car last week. Will included pic's when set up is done.

Why stagger?

If you don't have a good reason, no need to stagger the tires.

yeah, x2 on why stagger.

Run a square setup

OK, why square..

the car has mild oversteer, will get more grip from Hankook tires (compound & lesser sidewall) all around

seems back could use even more grip (and/or weight), hence more width

front could suffer from wider tires, harder turn-in

If you all are saying keep square for looks/maintenance(rotating) I understand.

If you all believe it would handle better than a staggered setup I'd really like to understand why

I know I don't want a car with understeer either

But I'm just an ex karter... it's great having a car with a wheel on each corner

All comments appreciated Thanks

mild oversteer is better than understeer. With 215/245, you'll probably end up with more understeer than you'd want.

Also, if your goal is handling, ditch the 20lb wheels.

If you are going purely for looks, your setup will work great.

I always am puzzled when people buy one of these cars and then are hell bent on dialing back the oversteer. There are literally thousands of cars that don't have that particular handling characteristic, why buy one of the handful affordable ones that is defined by it?

To each his/her own, I guess but it's just odd.

The car is neutral as heck. Any current oversteer issues you currently have are driver related, not car related.

So far, a car that is characteristically defined by oversteer and another it's neutral as heck and I'm a crap driver .

Thanks for something constructive "aznatama"

Truth about the car and a great handling setup is probably somewhere between this vast opinion.


Thanks anyway

Why square?

Because unless you are pushing out a lot more power than stock, 235 all-around is great for track use.

I can get the car sideways easily without even trying. I can keep it sideways if I want to clutch kick the car to hell & back.

Wider front (235) is not harder turn-in, not with street tires.

I have 245/255 for street use, and it works great too... but I don't push the car hard enough on the streets to know what works or not.

Your setup will yield more understeer. So you know what you don't want... put two and two together.

QED.

It is neutral. I can get the car to understeer or oversteer easily. That's neutral.


Never did I claim that you were a crap driver, just that the behavior of these cars are defined by the driver assuming fairly stock suspensions (obviously one could tune the suspension to make it tighter or looser). Give your suspension mods, the car is still neutral.


Slight changes in how you drive will fix any oversteer "issues" these cars have. Same as with the S2000 guys who used to do 180s in intersections.

are you going to autox or track at all? I spent a few autoX on stock wheels to see what the car did before adding grip, see what you think it needs. there is a general consensus that 245/40/17 square is a pretty solid setup. I thought the car was pretty netural with stocks most of the laps, during the event I only had to kick out the back end on one corner to compensate for a little understeer.

you just bought the car drive it for a while before you decide what you think it needs. Unless its a street only car, in which case do whatever you want.

BTW for future reference:

If you are soliciting a comment on this "wheel/tire setup", you will get vast opinions, up to (and including) comments about you as a driver. For all we know, you are just a name on a screen with no background information.

If you don't like it or don't appreciate it, you can always call Tire Rack for a different opinion.

No one is here to insult you, but you already have your mind made up it seems. So who cares what we think right?

BRZ is Neutral, and it is often described as an "Understeering" car when compared to an FRS......

My thoughts... You want to be the cool guy in the parking lot picking up all the highschool girls. LOL
