Square or Staggered?

[Snoopyalien24]

So all in all squared is the way to go to improve handling overall, and staggered for high horespower improved handling only?

Looks like they might come staggered stock. The JDM release party has info on the mm of the tires and they differ front to back slightly.

I'll be going with those simply because they're already on the wheels I'm using . I'm not about to sell year old tires...

Only if you want to improve handling performance. Without adjustable camber, I don't see this car having more than about -1 degree up front. A lot of us will want at least -2 up to -3.5 for Maximizing lateral grip up front.

This car has very different specs to those that the usual back yard racer is used to.

"Very different specs"? In what way?
I've tracked on McPherson struts, Chapman struts, semi-trailing arms, double-wishbones all around, multilink, etc., etc. in cars weighing anywhere from 2000 lb to 3600 lb. I don't see anything about this car's specs that are particularly novel. For sure it's been a WHILE since there's been a 2700 lb. strut/multilink rwd/irs car on the market, but there is nothing new under the sun...

That said, I don't see any benefit to going staggered, unless it's not possible to fit wider tires up front.

That about sums it up IMO. Squared will likely be better for 99% of people.

Also, I don't remember the last Subaru that didn't have eccentric bolts up front for camber adjustment. My guess is that some of these early preproduction models didn't have them but the actual production cars will. But....pure speculation on my part. Either way you wouldn't be able to get big numbers from the bolts but it would be nice to fine tune with them. I'm sure OEM bolts for other Subarus will work and they're cheap.

We will have some pretty unique camber plates for this car.

The OP didn't mention such absurd context, and Dave was making fun of such lunacy.

Who said "everyone"? Also, this is a discussion about stagger vs square... regardless of the car being stock or "boosted to the moon".

Added Greddy tire specs...

Front- 19x8.5-inch (+45mm) w/ Hankook Ventus V12 EVO 225/35ZR19
Rear - 19x9.5-inch (+35mm) w/ Hankook Ventus V12 EVO 245/35ZR19

I've driven plenty of cars with staggered setups, and square. Fast S2000 guys go from staggered to non staggered, gee.. I wonder why.

Add in the inability to rotate tires, etc.. I'd rather tune the handling elsewhere than running staggered setups, which are simply not ideal IMO for anything that's not MR or RR.

And with these cars if you do run staggered make sure your OD matches (or is EXTREMELY close ie 225/45/17 and 255/40/17) so when you get a flat in the rear you can still move the front to the rear and not cook the diff.

Not really. There are plenty of ways to move the handling balance back to neutral.

Regardless? Greddy's FD non-street car is hardly the typical application. Are you implying that their staggered setup is also applicable to a stock 86?

It seems you're disregarding the feedback of the only people that have driven the car [the media reviews]. Are you nut-swinging Greddy, defending your emotional or aesthetic preference for staggered setups, or do you actually have information regarding the 86 chassis that the rest of use aren't privy to?

However I doubt your fiddling will because of: "Hmm, I really want 215/30R19's on 10.5" +0 wheels in the front and 275/30R19's on 13" +0 wheels in the back, so how will I have to adjust my geometry, roll centers, dynamic camber and toe, and roll stiffness so that my uber-cool stanced car doesn't suck balls."


Heh...

You'll get more oversteer with square and understeer with staggered.

[Dsbj]

I'll wait and allow others to be the guinea pig.

I will probably go square to keep the balance and allow for rotation. May increase width but likely just good summer tires will do the trick. To go flush, that'll just come down to the right offset/spacer use.

Oh, and I laugh at needing to offset a 600hp car with a staggered big sticky setup. Be real. Many are attracted to this car not only because of its weight, balance, etc but also because it's easy on the wallet. If you're really going after huge power like that, start with a Corvette. 99.9% of forum members are not going to drop $20k on power upgrades.

Square on the track and weekend events, staggered for around town.

NO.

There is no feedback on how the 86 handles HP yet(except Tada's concern for suspension tuning if the 86 is supercharged). I am NOT talking about the "typical configuration".

I hope that clears things up.
