Alex’s 350z Convertible

We worked on Alex M’s 2004 Z33 ‘vert about 5 years ago and it is a familiar Z sporting Central20 bumpers, 5Zigen wheels and a host of bolt-ons. Alex travels around the world on business frequently so his car sat idle for a long time. With just 56k miles on the clock he brought it to ZCG for a thorough once-over.


A full 60k-mile service was performed, new battery installed, new thermostat and we sorted out all of the issues. First, the car was lowered without adjustable camber arms so we installed SPC f/r control arms and Whiteline diff bushings. A full alignment followed:


A few other issues were corrected like a failed oil pressure sending unit, passenger seat problem and blown stereo fuse. The Stoptech brakes were old/weathered since their install in 2004.  We upgraded them to yellow ST40/ST45 calipers, turned rotors and our favorite 309 pads:


The 5Zigen SMB wheels were re-refinished and wrapped in new Bridgestone S-04 tires:


The Z had many bolt-ons but had never been tuned so we put it on the dyno. Baseline numbers of 234hp/230tq to the wheels indicated it was low on power. Rob UPREV tuned picking up power everywhere in the rev range for a total of 254hp/257tq to the wheels, gains+20hp/27tq. This is a great example of having a proper tune to maximize gains from your bolt-ons whether it is DE, Rev-up, HR or 370. Alex is happy with the final product:

Scott’s 300zx Convertible

Scott N visited ZCG because he felt the suspension on his 1994 Z32 ‘Vert could be improved.  The Z33 Rays wheels look sharp on this 300! We installed TEIN coil-overs and a few other goodies:

Here are the existing shocks and the new TEIN street coil-overs going in front and rear:

Z1 upper control arms:


SPL tension rods so we could fully adjust camber up front:


The rack bushings are vey common problem on z32s so we replaced them. In the back: the aftermarket adjustable upper control arms were making noise so we replaced them with OEM parts and performed a full alignment.

Scott is super happy and Enjoying The Ride!



EVENTS: SpoCom Norcal 2015

Last Saturday I attended the SpoCom Norcal Edition car show held at Club Auto Sport in San Jose, CA. If you do a quick Google search of the word “spocom” you’ll find more images of scantily clad women than actual cars–this may explain why legions of adolescent males paid the relatively high $25 spectator fee, but more on that later. Look harder though and you can find some sweet J-Tin at this show claiming to be aimed at “automotive & pop culture tastemakers alike.”


The Venue

I don’t claim to be a tastemaster of any kind, but here is my review of the show from a Datsun owner’s point of view.  Let’s start with the venue: Club Auto Sport is a large, retail/commercial complex and home to exotic-car rental agency Club Sportiva and Borelli Motorsports:


Inside the main building there were several aisles for show cars to be parked and a main stage for a DJ and wait for it…bikini contest! Club Auto sport offers private garages so naturally I peeked at various man caves…found a Porsche 959 in hiding!


The Cars

Those tall orange “Swords” above are actually the coveted SpoCom Awards. I learned that this was a highly competitive show with “teams” vying for these 4-ft tall trophies. Here is a taste of the cars placed near the main stage area:


There were about 25 cars lining the aisles inside the building…scattered about in random fashion with one aisle having only 3 cars vs 18 in another:


The car scene inside the building was quite different from the cars placed outside, and this is where I found some pretty neat machinery. Let’s begin with my roadster which was staged near this S30 sporting an old-school body kit:
