NZeder's Datsun 260z Build Thread

[nzeder]

Hi Dale, now that is interesting. You see I have never taken the rules as you have pointed out. I will quote your post from above.

"original materials as per STANDARD SERIES PRODUCTION VEHICLE” and then this gets over ridden with “Period modifications are permissible”

I have never read the rules that way. I read it as "stand series production vehicle" without the other over the top of that. This is how I come to the conclusion that an escort with bubble arches (forest flare) or an ISMA 240z (pic off car #33 above, that car in question is a good story) is not T&C as they don't have standard series production body work. The should however fit schedule k if all other components fit schedule k ie escorts with arches must run 13" rims as that is all that was used in period with the flares.

Now to answer your point about NZ racing. The 240z did not start running here in NZ until after the Datsun Z Club formed in 1981 and it took a few years to the marque accepted by others so 240z started to actively race at taccoc, datsun z club, lotus club and other until mid 80's so for NZ racing period correct.

If Ricky's car is to represent the period "era" of one of the international zeds then sure ideally the front should change. I guess after Ricky's car was damaged (only panel not bent was the roof) then he could have imported an isma body kit like the car above thus giving him 14" more width in the rear 7" a side, running 15x15 rims or 15x12 for wets and have hugh grip and therefore be faster than he is now but still be 100% 1975 period correct.

I have thought about building an isma 240z after all they won the 1974, 1975, 1976 and 1979 GTU driver championships and manufacturers championship in 1975, 1976 and 1979.

My understanding is as you've written here Mike. Using the Escort as an example, you can either fit larger diameter wheels as per T&C, but you can't fit the forest flares. But under Schedule K, you can fit the flares, but you must then run original diameter wheels, as raced on in period. I view Schedule K as being similar to FIA Appendix K, in that what you're essentially building is a car that is a mechanical and aesthetic replica of a car as it raced in period.

A common sight in NZ classic racing, is when people mix and match T&C with Schedule K: eg (using the Escort again) they'll fit the forest flares as allowed under Schedule K (but not T&C), but then also go up a size in wheel diameter, as allowed under T&C (but not Schedule K).

But that just my interpretation of the rules, and it seems I'm just as confused as everyone else.
