All Classic Japanese Series

15.Composite panels may be used but only if originals are no longer available – all cars must weigh in at a minimum of 90% of their factory curb weight.
16.A roll cage to MSNZ specifications must be fitted.
17.Interior trim may be removed but door cavities must be covered. Aftermarket dashes may be used. An approved race seat and harnesses must be used. Passenger and rear seats are not required.

that sounds like room for ripping everything out and balancing the car as long as its to curb weight is factory, useing steel weights n stuff in the frount and back

[Dell'Orto]

so basically it has to be a standard as old car BUT has to have roll cage? who does that?... if your going to bother putting in a cage then you would want to upgrade everything else too. apart from that it seems like a really good idea!

Well no, read the rules - engine and suspension mods are free, provided its the original motor and original suspension mounting points. Meaning you could use an AE86 with coilovers all round and powered by a Formula Atlantic motor

What was the AE86 new, 860KG ish? If so then you have a minimum weight of 775KG ish and I would think a full Atlantic motor would struggle with that weight, not enough torque. The TRD Group A engine spec would be better IMHO with more torque and better mid-range with the injection.

Short diff (4.77 or >) and TRD gearset should help with that.

1.07 is pretty fast on road rubber TBH.

Road Legal rubber, there are some pretty grippy tyres which are road legal.

Dunlops, toyo's etc, all realistically road complyable race tyres

[mjrstar]

i reckon that need a more open class that is not so heavily regulated. ie: engine transplants, an mild body mods, that way you could have some wild road registered cars out there tearing up the track. I don't think the cars will be wild enough to make the racing exciting to watch.. time will tell i guess...

Its called OSCA, or SuperGT. You probably want to go further than you could achieve with a road registered car.

[Leon]

Yep, there's about a million classes out there that cater for a fast club car.

Every second year or so, somebody writes a set of rules that really perfectly suit the car they own and race, then they try to get enough cars together. Meantime, everyone else moans that the car they already own will need something done to it to meet the class requirements.

Then after x races, they merge with another class to get numbers up.

Yeah for sure but then again there are slicks

At Puke the difference for most cars from DOT approved to full slicks is 4-6 seconds IIRC. So you are going to have some QUICK cars doing 1.07's on DOT tyres.

[Emperor]

my best is 1:08 on Toyo RA1

and thats in a Pro7Plus Spec batty?

[Emperor]

Weighing 1190kg, 190kw at wheels, so prob bit higher power than your average classic stock car.. But imagine a turbo starion or something lol

[strx7]

alot of the vehicle that would run in a class like this would be lighter though so it gives a good indication.


Was Barry running full slicks or semi slicks for the NZPC Time Attack day there???

[rollaholic]

semis iirc

ae92 levins would qualify too

tho not with a 7agte haha

[strx7]

semis iirc

At Puke the difference for most cars from DOT approved to full slicks is 4-6 seconds IIRC

So you're saying Baz would go sub 60's on slicks....................

If the rest of the package is up to it probably.

That time difference was a race preped Porsche on full slicks to DOT tyres, however it was a few years ago and DOT rubber may have progressed faster than the slicks.

And I was wondering what I was going to do with this when I had finished.

Have to pull those flares off dude

[Leon]

Depends if he can come in under 'it was a factory option' clause. Although in another clause they mention wheels being inside factory guards.

[TRD Man]

They were never a 'factory' option.
