Also according to the rules a 2" increase in rim width & dia. is allowed, so as the 280z & Z432 both used 14x5.5" inch rims a 16x7.5" rim is technically allowed, even though many seem to think a 7" is the max allowed (mainly due to porsche guys that complain I think) as the standard 240z & 260z used a 4.5 to 5" rim (depending on location..?)! (pitty the factory didnt go through with the Z432R rumoured use of 15x7 magnesium rims, but instead opted for the use of 14x4.5 steel rims as they stated that race teams will use their own rims and therefore it would be an unnessessary cost...arrgghhhh where was the foresight?!)
Yes in the case of the Z432R that's true, but the regular Z432 and Fairlady Z did have magnesium wheels. The Z432 had them standard, and the Fairlady Z had them as an option. In Portugal they were standard equipment on the 240Z. They were 14" x 5.5J
The Works rally cars also had similar style mags in 14 x 6J and 7J
I guess it just depends on how the CAMS rules define "standard wheels", whether its what was available in Australia at the time, or world-wide.
I wonder how the rule is applied to Porsches, Australia only or world wide.
