Robi’s 370Z was built to show just how fast a fully streetable 370Z could go in full street trim with street tires and a daily driver friendly suspension system. The car is amazingly stock. The VQ37VHR engine is completely stock with the exception of a lightweight 3″ single outlet, center exit exhaust system built by Robispec and Motul 300V 5W40 superoil. Currently even the downpipes and cats are stock. We guess that this exhaust is probably worth about 6-8 whp over stock and sheds about 60 lbs of weight. Robi muttered that the car only made around 260 rear wheel hp on his dyno, which is about what we would expect for a stock 370Z with exhaust.

| Robispec makes one of the 370Z’s lame cosmetic features functional by putting the exhaust right through the middle. We really love the looks of this exhaust system. |
Often tuner cars reflect the creator’s personality and Robi’s cars always have a unique feel to them. They are forgiving and easy to drive at the limit. Robi is mostly known for his work with the Mitsubishi EVO and Subaru WRX but Robi’s work tames the notoriously hard to drive Honda S2000 into a smooth riding touring car that your mom could lap quickly at Buttonwillow. Similarly his 370Z can tear it up at the track and drive around town no problem. Robi’s wash and wear, stock engined 370Z was less than a second behind Import Tuner Magazine’s 500 plus hp, twin turbo monster 370Z with Formula D driving ace Tyler McQuarrie behind the wheel. From working with Tyler at Falken, we know that his natural driving gifts are far beyond drifting. Bolting in the Tyler steering wheel gasket is probably at least a 2 second a lap advantage over other talented drivers.
The real magic of any Robispec car lies with the suspension system. The Robispec 370Z starts with a good, yet reasonably priced base. KW Variant 3’s are used all around with a twist, Robispec valving with a foot valve with a higher blow off rate giving a slightly more digressive compression damping curve. The additional low speed compression damping gives a snappier response to driver input and a little more body motion control than the standard valving with little ride penalty.
