That was the key, and a first lap melee behind Dave allowed the Z to stay up front.

But even then it was a struggle- I saw what was left of the A7s after that race and there wasn't much (corded). If Dave had any more pressure, or the Mustang driver had not panicked at a last ditch attempt, the Z might not have emerged the winner. The SCCA tech crew ordered the Z torn down and--to my knowledge--is still the only 370Z competing in SCCA T3 competition for 2015.

For us west coast time attack junkies, please tell us what the "SCCA's reputation" of the Z is? For us out here, it's a good enthusiast class time attack car. martin is working on it becoming a good limited class car. everyone seems to agree it is not a good "street" class car. Serious question.

Our specs are basically:

Enthusiast: Full interior street car with bolt ons, 200 wear tires, no engine mods, no non oem Aero. 2 way coils, sways, and springs allowed. Allowed driver seat replacement only.

Street: tire limits, 5"/roof limit on aero(no active). , turbo 57mm and SC limits 68.5mm, no lexan, still 200 wear tires(I think), can remove full interior,

Limited. Lexan permitted cept windshield, CF body panels allowed, body geometry modifications allowed, no turbo/SC MM limits, UTQG 60.

Not sure how that stacks up to SCCA classing, but can tell you we would get totally screwed in the street class.

From the 240Z onwards, the Z has had an enviable competition record. With National Championships for almost every model from the S30 through the Z34, the Z has been viewed as an overdog for some time now. The SCCA competition racing board (CRB) currently has given the Z34 and the Z33 (HR-powered) one of the highest weight penalties (cars must weight 3400# with driver) in the T3 class. The VQ37VHR must also utilize air restrictors (50 mm) to limit top end.

Of course, there's other classes where you can race the Z unrestricted and at a lower weight, but you get to take on cars like the C7, Ferrari 430 comp. Porsche 997 GT3 and the like.

And I would say the same is true out here in TA. Since our enthusiast class has a 45K off the lot list price cap, the only cars conceivably faster than it in its class are either cars that are built to spec and a few years old, or , that's about it really. Old M3's, Old C4's, etc that have depreciated and have been designed to win in that class. However the Z has big challenges being competitive in the "street tuner" class. Namely HP/Weight issues with the tire spec vs boosted up 2500 lb cars. Would be very expensive to bring a Z34 to that level when instead you could build a 240SX which has dominated TA out west in those types of specs.
