tire stickers

SEMA is a hard show at which to properly appreciate cars. On one hand – it’s a show overflowing with some of the best builds you will see all year. On the other hand – it’s that same overflow that makes it almost impossible to keep your wits about you. It’s almost too much of a good thing. In a sea of thousands of cars, I feel like some inevitably get lost. The great thing is: The cars that are truly memorable, the cars you are talking about weeks and months after the show… are cars which rise above the temporary flash-in-the-pan Instagram fame. Some cars deserve to be immortalized. More than digital noise or passing fancy, they draw their inspiration from the timeless. The classic. 


This 240Z certainly qualifies as one of these cars. While it has some innovations and forward thinking design elements, it also honors the tradition and legacy of Datsun’s Z car heritage. Car owner Dennis wanted a Z that could be as menacing on the street as it was on the track. In looking to manifest his dreams into reality, he was fortunate enough to meet aspiring builder Kyle Kuhnhausen. Kyle is a fresh out of business school automotive entrepreneur with a penchant for metal work. Ok, more than a penchant… he has a gift.  From the paint scheme to the heavily gusseted cage, this car is well thought out & beautifully executed. How well executed? Well, when we talked he made sure I knew that the LS swap was a place holder engine until they built something truly epic for under the hood. WOW. Some place holder. 

Let’s take a moment and revel in my three favorite aspects of this car. 



There is the paint scheme. Nimbus Grey (or battle ship grey in some parlance) has to be my personal favorite hue on show cars. It’s rich, it allows shadows to adopt a deep dark over tone, and light reflections to be silvery & pronounced. Every truly beautiful design looks amazing in this color. So… win number one? CHECK! The Peter Brock homage striping is as evocative and respectful of the Z’s motorsport heritage as it is a tasteful modern touch of racer bravado. I dig it. Those famous side stripes actually start on the hood at the vents and then cascade over the fender and down the side forming the Brock stripes we are all familiar with. A killer design cue that is at once forward thinking and period correct. Nicely done. 


Let’s talk about that metal work. The Aero is mean, functional, and gives the car a seriously provocative stance. What’s more – it’s designed to just rip/break away cleanly in the case of a momentary lapse in driver skill (for example paying a visit to say, China Beach at the end of the straight at Mid Ohio). Well played Kyle, well played. However, as fantastic as that aero is, it is nothing compared to the beautifully executed roll cage. Meant to be a street car that can participate is serious track time… it had to be a car from which Dennis could easily get in and out. Kyle kept the safety high by fabricating one seriously artful, yet stout, fully gusseted integrated cage. Take a few moments and look at the cage in this car. I have severe race car envy. My race car has race car envy. Seriously. It is so good that it easily merits adjectives like superlative, excellent, exemplary. Bravo. 


And this is one where so many cars sort of take a pass… the gauge cluster. When a car has track day toy duties, it’s easy to just pick up a digital display, mount it up, and just call it done. Not in this car. The cluster in this car is 13 individual pieces of aluminum lovingly hand shaped into what you see before you. It honestly called to mind some of the extreme and bespoke modern interpretations currently en vogue built around the Porsche 911. The Singer cars being the most notable, they take an air cooled 911 and massage every aspect of the car… and polish, preen, & refine it until it is absolutely jewel-like. The perfect 911. Well, that’s where this Z took me. It’s like a really nice 240Z… only polished to the highest possible degree. Everywhere you look there are tasteful touches. This instrument cluster exemplifies that. The angle at which it is canted toward the driver, the alignment of it inside the MOMO wheel. It’s absolutely glorious. 

So yeah, this car is one of the highlights of last year’s SEMA show. It truly was. Bespoke modern takes on past classics are hot right now. Cars like the Singer 911s are fetching 500k and more per unit, so it makes builds like this kind of a serious proposition. Get it right and the value and classic status is legitimate. In the end, Dennis can drive this car on the road or the track, confident in the fact that he found the perfect enthusiast to execute his vision. And he can rest well in the fact that he’s now driving the Singer of Datsun 240Zs.
