Sporty G37 thread

With the tires that close to the fender, you're going to have to roll 5sure. That purple car has a slight pull in fact.

With enough camber you may be able to get away with a slight roll but even then I wouldn't be so sure.

Why not just spec wheels that fit instead of f'in around with spacers

[12,000 RPM]

Because stance is life bro.

[12,000 RPM]

OK, I gotta get the ball rolling on this shit. Friday night, gonna take off all my wheels and go get the new shits mounted. Then while they're doing that, swap the front studs to get the spacers on. What a mess But it's going to be so sick once it's all together.

Sounds like a fun Friday night.

I don't see the wheel change appreciably hurting the ride.  The sides of his dark colored car getting covered in dirty road spray when driven on wet roads, or stone chips, is the most likely issue I see.  There's a reason tires are spaced to align with the fender lip near the bottom of the car, where the car is narrower, rather than the top of the arch.

But that is like the absolute limit. Praying I don't need to get fenders roll't.

WUT      

that would be wacky.

Yeah, that's gonna be a PITA.  There's a reason I have mud flaps on my truck, and it isn't necessarily for style.

This reduces street cred.

I want mudflaps, but for style reasons.

Stretch.

Can't wait to see the first ever G37 stanced on Giovanni wheels.

[FoMoJo]

I haven't been keeping track.  Is he putting coil-overs on it?

I'm gonna jack up a rear corner tonight and really see how much clearance I have once the tire begins to tuck. Front tires will need an extra half an inch and the back won't change.

My back tires are already essentially flush with the fender and I haven't noticed any extra grime or damage.

Back tires don't steer.

I'm in.

What's the final setup actually?  What coilovers, what kind of drop, alignment specs, etc?  Wheel & tire size?  Sounds like pretty aggressive stancing.  If that's the case, I don't think handling dynamics are necessarily the end goal.

[Cookie Monster]

Won't the car be extra oversteery with almost an extra inch of track width up front?

Weren't Pontiac Grand Prixs designed like that?    They had a huge difference between front and rear track.

[12,000 RPM]

Final setup will probably be:

- 19x9.5 +35 wheels and 255/40 tires square forever
- Reasonable alignment specs (~-1.5/-1.75 camber F/R, zero toe)
- Tein Flex Zs (Basic Zs are actually really good on the street but just a hair soft. Would be nice to have adjustable damping too)

Goals for this were, in order of priority
- Aggressive fitment
- Reasonable cost of operation/ownership (so no 305s or w/e, no super sticky fast wearing tires, no crazy alignment; square tires were mandatory)
- Good handling/ride balance
- Low road noise (so again no super wide tires)

I think it will work. I was just foiled by the OEM BBK; it's always a crapshoot with that. I would have thought a low offset wheel would mean MORE clearance, but that was not the case.

Yeah, for ultimate FWD cornering grip and mega s/c 3.8 utilization.

They also did it back in the day on the Bonneville. Google "Pontiac Wide Track."

The V8s had reverse stagger tires as well.

[93JC]

"Wide-Track" was an old Pontiac ad campaign going back to the '50s, and it was more marketing pap than anything. Latter-day Grand Prix GXPs had a wider track in front to accommodate the 5.3 L V8, but regular V6-powered Grand Prixs did not. Pretty sure the Impala SS and Bonneville GXP did too.

EDIT:

The V8s had reverse stagger tires as well.

255 vs. 225. As far as I know that's where they got the extra axle track from: wider, deeper wheels. I don't know that the underlying suspension was any different between V6 and V8-powered Grand Prixs but I don't think so.

[r0tor]

Why in the world would you run more camber in the rear then front?

[12,000 RPM]

That's how the suspension geometry works. I might get a camber kit for the rear

[r0tor]

Remind me to get more popcorn

It was suppose to help with torque steer..........

The staggered tires helped with terminal understeer.  Wheels/tires don't affect torque steer (that's up to halfshaft and suspension geometry).
