Tanabe NF-210 Sport Springs Infiniti Q50
The Infiniti Q50 (the replacement/rebadging of the G37) is a new car to the market, and Tanabe already has you covered as far as getting your height in order. Their NF (Normal Feel) springs maintain the luxury ride of these awesome cars, but lower your stance 1 inch in the front, .6 inches out back. Click the picture to order a set for your car!
One of the most frequent questions we get is “what size tire do you recommend?”. The most correct, but least awaited answer we can give is “It depends”. Because frankly, tire size doesn’t really mean a whole heckuva lot.
We’ve been taught, through some sort of mythical passdown of inaccurate information, that the first number in a tires size (let’s say, 275) is it’s width, in mm. If that were true, things would be simple. When you go into a store to buy a new shirt, you see the same phenomenon. Some firms clothing runs bigger (or smaller) than others. You may wear a 34 jean from one company, and a 36 from another. Modifying a car is similarly inconsistent, and rarely is simple. While the first number in a tires size CAN be it’s width in mm, it’s more often than not, a general target of width. Now, on an otherwise stock car, this doesn’t really matter. When you start altering suspension, dropping the car an inch (or more), fitting super wide, super low offset wheels, your margin for error decreases exponentially. As the Pauli Exclusion Principal generally states (and was reinforced by Einstein and many others), 2 objects cannot occupy the same physical space at the same time. So in the interest of avoiding tire contact with the body of the car, with suspension components, with the inner fender liners, etc, things become more complicated.
This pictue is one Kwame posted several years ago, and it illustrates the point perfectly.
If you saw the above picture, which tire would you say is bigger? The one on the left clearly. But on paper, the tire on the right is bigger. Both are mounted on the same 11.5 inch wide wheels. The tire on the left is a Michelin PS2, 295/30/19. The tire on the right is a Pirelli PZero, 305/30/19. If you’re trying to get more “stance”, or gain a bigger footprint, which would you rather have? The one with the bigger number on the receipt, or the one with the bigger physical dimension?
Here is another picture of the same above example: 295/30/19 PS2 on left, 305/30/19 PZero on the right
So what do you do? Check the manufacturers site! Everyone should have the physical dimensions of their tires, in inches, for every corresponding ‘size’ listed on their website.
A close friend of ours down south has a 350Z. For the last several years it served as faithful daily driver, and weekend track slut. Now that the stars have aligned, and a truck now handles daily driving duties (and doubles as the track-rig on the weekend), the Z has been relegated to primarily track use only. He runs the car all over the Southeast, and despite the fact that it (for now) is still a stock engine with some bolt on’s, it’s wildly competitive. The reason? Intelligently selected modifications. Everything on the car has a purpose. Nothing was selected by accident, and in several cases, it took some trial and error of different components in order to come up with the faster combination.
The car was recently in NASCAR country, North Carolina, for a recent round of upgrades, including a differential and ring and pinion change. While there, a former NASCAR tech got hold of it, and using some fabrication skills and NASCAR carbon splitters (the rear deal), this was the creation. Next set of shakedowns is a few weeks ago at Barber, stay tuned!
Best of the best on this 350z – Endless Racing 6 big brake kit, Zeal Coilovers with Eibach race springs, Roberuta Cup Kit (to adjust height on the fly), Esprit forged adjustable a-arms, and a bevy of Whiteline and SPL bushings. The end result is going to be out of this world, stay tuned!
Super clean R33 GTR featuring an Endless big brake kit (Mono 6 brake kit front and rear, tucked neatly behind NISMO 18 inch wheels). A stunning result (both in looks, and certainly performance). Need an Endless kit for your car? Drop us a line at z1sales@z1auto.com and see what the premier brake supplier has to offer. If you’re truly looking for the absolute best kits out there, no one offers the range of performance oriented options that Endless does. Simply the best.
Looking for a quick and affordable way to reduce the body roll, and increase the cornering ability of your 2003-2008 350Z, or 2003-2007 G35 coupe (or RWD sedan), then the ST Swaybar set should be on your To Do list. These are a solid steel set of bars front and rear, and unlike some competitors, include the required bushings. At $355 for the front and rear set, it’s a hard deal to beat.

The last wheel you’ll ever need!
This new wheel is the ultimate for sports and GT drivers, seeking an all in one solution. It combines critical engine data via the engine ecu, combined with GPS track data, and camera data, in a series of customizable pages. Allowing you instant access to multiple channels of critical data. In addition, it features customizable shift lights at the top of the rim, as well as customizable alarms for various user-programmable warning thresholds. There are also user-customizable multi-function buttons allowing you to enable/disable various functions such as traction control, pit speed limiter, radio communication, etc). Using a sequential transmission? No problem – optional paddle shifters are also offered for a seamless integrated solution. Data derived from lap times, speeds, etc can then be played back by the driver at the end of a session right on the wheel display. It’s thoughtfully produced in either 320mm or 350mm diameters, with carbon, Alcantara, and leather for the ultimate combination of strength, weight and grip. The leather features a special cool system design, which reflects sun rays and keeps the grip surface cool to the touch.

Audi B7 Avant on a fresh set ADV1 ADV005. While I’m not a real fan of the tucked look, I just know that with maybe a 1/2 ride height rise, this car would be an awesome daily driver. The wheel design looks awesome with the long lines that the Avant’s have. Contact z1sales@z1auto.com for all your ADV1 custom wheel needs.
Tomei Japan has just released 2 new items for the Subaru WRX and STi.
First up is an all new manifold design – a 4-2-2 setup for twin scroll cars. This will fit the GDB, GRB and GVB chassis. The primaries are 42.7mm, and the up-pipe collector is enlarged vs stock at 45mm. it also weighs 7.49 lbs less than stock as well! Like all the Tomei Expreme Exhaust products, it comes with all quality gaskets and hardware (no cheesy paper crap here!), heat wrap with ties. This is a true motorsport grade part, without the exotic price tag. Full details are on the attached PDF flyer
In addition, Tomei has released their new Expreme Titanium exhaust for the GR/GV STi (hatch and sedan). Thoughtfully produced in both JDM spec and USDM spec, so there is a version for everyone, regardless of your downpipe spec, and regardless of where in the world you live! This is the ultimate in lightweight, high power exhausts for these cars. Traditionally, Titanium exhausts elicit want and fear in a customers eyes. Everyone loves the look, loves the weight, loves the sound…and hates the price. Tomei has broken that mould. Their titanium exhausts are of exemplary quality, intelligently designed, expertly manufactured, and are far more affordable than many lesser exhausts. The US Spec exhaust weighs 34.8 lbs LESS than stock, the JDM exhaust weighs 35.3 lbs LESS than stock – and this is just for the catback! It’s a slip fit design, so no drama with leaking gaskets. But like many modular motorsport level exhaust components, it uses spring clamps to ensure a tight, neat seal. For those who are using this on the street, it includes a removable silencer to keep net volume at a tolerable level. Or, run it without the silence, and wake the devil.
For best pricing on both of these components, or a combo with a Tomei downpipe, turbo, or any other item, drop us a line at z1sales@z1auto.com
