Sporty G37 thread

I might consider a square setup instead of the factory 225/245 stagger, but 245 all around with a good tire is plenty for the street.  IME, a front-heavy RWD on staggered tires tends to push more in off- and neutral-throttle cornering scenarios.  Shouldn't ding your fuel economy much, either.  I think I lost 5-6% going from 225 square low-rolling resistance "touring" tires to 255 square hi-po summers (with larger/wider wheels) on my last car.  I went from 205 sport all seasons to 215 sport all seasons on my Mazda and I don't recall any hit in fuel economy.

Are you keeping the Civic?

Hell no The chowderheads who did the swap missed a ground or something I think; radiator fans and A/C clutch aren't working at all and it's doing weird things with the coolant temperature. Once I get that sorted (under warranty) I'm gonna get it detailed and put it on the market.

If the stability control is similar to what was on the Z, running a square setup, at least with the same aspect ratios, will be problematic. This thing has the same size tires as the Z with ~500 more lbs. I may try 245/265s.

Two things I would like to fix sooner but will probably have to wait on... suspension is definitely more floaty boaty than I'm used to. I would love a setup with the feel of that E60 535i sport; that thing was perfect. Some coilovers with mild springs (prob 9k at all corners- ~30% stiffer than stock) would do it. Also after having the 50W clear lens projectors on the Civic these OEM fuzzy 35W projectors are weak sauce. But neither is really pressing, I can probably wait a year or so to fuck with that.

Stock tire size on the G37S was 225/50 front, 245/45 rear.  These have the same overall OD (ok, the fronts are a whopping .6% bigger).  A 245/45 square setup will be invisible to the stability control system.  This is in contrast with the Z (or my car), which runs staggered widths on the same aspect ratio, so the tires have different ODs front to rear.  It's not a huge difference (~3%) and I've heard of plenty of people, at least with PP equipped Mustangs (non-PP cars run square tires by default), switching to square setups without causing issues with the ESC.  But I don't know how particular Nissan's ESC programming is since all Zs came with staggered tires.

And if your car is running 225/50 front and 245/50 rear right now and you are having wonky ESC responses, assuming Nissan's ESC programming truly is that finnicky, it's because whoever cheaped out on the Nexens also put the wrong size rear tire on the car.

lol you need my guy. He could do an R18 Civic in his sleep.

Naw they got the right sizes, I just checked. I assumed they were staggered in radius since the Z was. If I can go all square I might go 255s if I change wheels. That would let me rotate tires too.

Nissan ESC was pretty finicky. I heard of people getting ESC lights running square setups on the Z. ESC system was pretty ham fisted too.

That's why new cars suck. So unfriendly to mods.

[12,000 RPM]

Cars start at such a high level now modding is mainly for taste anyway. Going to redline in this thing takes too much commitment for the street, even merging on the highway. I still want the suspension tighter though.

Nah. Show up to an autocross with a stock car and you'll get destroyed. New cars are certainly better than they used to be, but still very compromised.

Z was 11 years old w/plenty of life in it when I sold it. I ain't

Well, I wasn't implying it will go up in smoke at age 10. Just seems like the path to a perpetual car payment.

I'm OK with that. In the end it's all depreciation, financing, and transaction costs anyway. Key is to get cars I can live with for a long time

That's a fair point.


Regardless, nice choice, enjoy it.

First commute. Jesus Christ. If this thing isn't as fast as the bike it's damn close. 20 mpg though

So nice to have a car with a good stereo and the road isolation to enjoy it. I was jamming today

[Laconian]

20 is pretty good for the G lol

[r0tor]

Hah... I get better mpg in the RX8

[Laconian]

With a stick tho

My Civic would walk it tho

Brakes are shot... crazy vibration. Ordered Centric blanks and Hawk HPSs. 355mm + 4 pistons up front, 350mm + 2 in the rear.... gonna be sick

Decided on the suspension too... going with trusty Koni Yellows and H&R Sports. Been looking into it and coilovers seem to have problems with clunking in the back, plus I have a sour taste in my mouth from those STs, which are by KW, which blew their rears in less than a year on smooth ass NC roads Stance is fucking meeeeeaaaan

[MexicoCityM3]

Nice. That suspension sounds good. I'd probably change fluids too.

[12,000 RPM]

I have some ~3 year old Motul 5.1 I never put in the Z sitting in a junk room.... I will do the right thing though.

[Rich]

brakes are probably just material deposits on the rotors from sitting on the lot.  Many hard stops might cure it

[giant_mtb]

Settle down.

[Cookie Monster]

Settle down.

Maybe the bike is that slow?


That lowered G looks good, man. I really want to get a set of rears to square my dad's G and lower it a bit. Stock ride height is terrible on these cars.

Vibration seems to be getting worse and worse. Centric blacks were cheap, rather just get it done and keep pushing. I have to do my wife's pads and the rears on the Civic so this is brake week at the sporty household.

[Rich]

I'll probably need brakes in a few months. I'll bring mine by this weekend too

These tires are awful

BFG Sport Comp 2. Better than DWS.

Great grip wet or dry, but they are LOUD above 30 mph.

Are they? I can't tell on my car. (also I have the A/S version)

Haha I don't have a big V8 to drown it out, I have the summer version and I can't wait for them to wear out so I can get something quieter.
