I highly doubt with the stock legal maximum offset of 30mm you would be able to get a 295 on without hitting the strut...almost certain. At a 35mm offset there was very little room between the strut and also the bump stop. The 295's on the back should not be an issue though. I had 295's on a 18x10.5 from my EVO on the back with out any issue.

I have driven one of the turbo 4 cyl models on our track. I was just showing the car's owner a line and wasn't driving all out, but it felt pretty good at 8/10's.

At the National Street Tire Challenge, one showed up and made it into the top 5 IIRC.

Sorry to dig up an old post but Ive actually been eye'ing this coupe for awhile now and there are a couple of things that do make it impressive. Although the performance is no350/370, its close and definitely no tiburon. But what's impressive is that its able to perform this on low grade fuel and pushes an epa of nearly 30 mpg! Its like the ultimate economy sports car.

A few weeks ago, I came out to my car parked in a parking lot and next to me was a car that at first I thought was some kind of Lincoln or other big-*** sedan. After I got in my Z and was backing out, I realized the emblem on the trunk was a Hundai and then I noticed that it was a Genesis Sedan. That thing is huge!!! I have still not seen any coupes to compare against but if it's anything like the sedan, I can see why it's in the 3200 lb range.

Compression or boost levels must not be very high, and it doesn't kick out that much power compared to other turbo 4's and v6's. As for epa fuel economy, throw it out the window, at 55-65 mph, I can get around 33-34 mpg in my Z.

The Genesis copue is no joke. In turbo form, it is one mean sleeper. Its underated as far as horsepower is concerned. People are reporting 190 WHP from a Flywheel rated 210HP. Once the aftermarket breaks it open expect a crazy cheap time attack/road race vehicle.

Here's a shot I got of a couple at WSIR for those of you who haven't seen them...

I can't figure out why they are so excited over it, especially after hearing the specs - 210hp, 3200lbs, 19" wheels. From what I read, there's no aftermarket for Hundai parts yet.

They could have bought a 370Z which weighs the same with 330hp. Lots of aftermarket stuff available or coming soon.

What am I missing?
Dave--I'm way late on this, but I think know the couple you're talking about. Jeff and Jean S. Good people.

My co-driver (also on this board) for most of the last two seasons also co-drove their MINI locally and at nats.

The logic behind the switch is that with the MINI S out of G-Stock, and the Genesis in, it's potentially the car for the class. The only other options are older front-drive sedans that never showed well against the MINI. From their results around the region and seeing some other Genesises (that's unfortunately the correct pluralization) run, they may be on to something. Pure weight/power isn't enough to explain autocross performance, as I'm sure you know. Otherwise the Z should have cleaned up on the RX-8. There's some magic to chassis design at play.

Also, the 370Z may prove to be competitive in the new C-Stock, but it's up against the RX-8, Mazda MS-R/trunk kit cars and the Solstice Z0K/conversions. Being wider, heavier and MUCH more expensive on tires than the competition, I'm not sure it's a safe bet. It's also not the same price as the 2.0T R-Spec, which starts at $23,750. The cheapest 370Z starts at $29,990, and you'd really want the Sport Package car, which starts at $32,990--almost $10K more.

As for aftermarket parts, they're running in a stock class, so all they can do is cat-back exhaust, front anti-roll bar, shocks, stock-sized wheels, and tires plus some odds and ends. There's bound to be a way to put Konis underneath it with custom mounts, there's plenty of wheels to choose from, a local shop can do a custom exhaust, and tires are on Tire Rack. That only leaves the bar, which will come soon enough.

It'll be fun to see how things turn out this season.

What? 33-35 mpg on a Z?? A bit of exaggeration I think, unless your commute is like 5 miles of downhill coasting... Plenty of threads on here that discuss this but most of us are in the 20mpg range. But if you really could get 33mpg on the Z, I bet you could get more on the 2.0T but with 85 octane fuel.

I agree though, from what I've read, the performance of the Genesis seems to less than similar engined cars. But it doesnt seem to be significantly less. And this is only talking about the 2.0T, whereas I heard there is even more potential with the 3.8 V6. And thats under $30k which includes full options comparable to the G37. Its quite a bargain, as the post above proves to state.

Yup, that's them. I'll have to watch AutoXforum to see how it works out.

I get around 27mpg at 70-80mph on bigg-*** 19" wheels/tires. I used to get close to 30on narrow stockers. I can see somebody breaking 30 mpg at 50-55mph on 17" tires driving ever so carefully.

I would say it's comparable to a G35 coupe. There is a tad more leg space in back seat though.

Got a chance to work underneath my buddie's 2.0T GenCoupe and I was constantly reminded of the 350z's suspension. It just had less beefier tie-rods, connecting arms and what not. Hyundai claims the chassis is stiffer than an E46 M3.

I also get 28-32mpg at 60-70mph on my "performance" map.

The aftermarket is already there for the Genesis coupe.

Yeah, the MPG thing is not uncommon for highway/freeway driving on flat road. But if the road gets hilly or you start counting city driving (stop and go) the 20-22 MPG is back in play.

When I used to commute "the back way" to our old house (some hills, nothing horribly steep), I could pretty easily average in the 34-36 MPG range at 50 MPH -- until I got to the big hill, then my MPG went down.

As far as the Genesis Coupe (the turbo one), it may be good, and the price is certainly better than the Mini. We'll have to see about tire wear and how they actually handle. Who knows, maybe someone will bring out another car that has done well against the Minis (although finding an "unmolested" one might be a bit of a chore).

At one trip to Willow Springs, a Rhys Millen driven V-6 Coupe ran similar times to the Double Down 370z on the same day. For reference they both recorded 1:37's and looked similar in the amount of prep/mods done, Tires, coilovers, exhaust and intakes, brakes. Notiably, I think the Genesis had Stoptechs and the DD 370z didn't, vice versa on the exhausts. (Same Genesis pictured above).

Rhys Millen > a time attack driver

but by how much is hard to say...

Willow Springs Lap times for some comparison, a Spec Miata does it in 1:38...

True, but Mike Bonnani in the Double Down 370z is a very competent driver, and the cars were mod'ed in similar forms (most importantly on similar tires - treadwear 180-220). Whereas that spec Miata is probably on DOT approved street "R"ace tires with a rating of 80 (r888's).

I think they are prep'ed with similar mods. And the difference in drivers should be minor.

Rhys Millen Genesis
