Nationals.

[OZVENOM]

At the Qld club Breaky on sunday the topic of street class came up in our breaky chat . it went like this how are they going to enforce the guide lines for strreet class at the nationals how? do you determine a stock engine? how do you determine a street tyre ? and why is it only 15" rims when probably 50 % of cobras built now have bigger diameter rims ie like my cobra has 18" rims but has normal road tyres not racing spec. the tyre problem is easy to solve as the tyres have a wear rating on them the lower the number the softer the tyre most of the racing rubber is 80 or less and most normal road rubber is over 200 so pick a number at which a tyre becomes a racing tyre say below 150 as an example.
I was thinking about putting my cobra in street class as it now is not turboed and runs on std road rubber no roll cage and a very stock 4.0 ltr engine. so is it a street cobra now or is it a race class car it has brakes which are standard on the harrison kits and the suspension is to there specs too. this is my questions for you all to ponder I await your responces.

Street class could be loads of different things.
How could rim size on an individually constructed vehicle denote whether it is stock or not? The size of rim plays no different a roll as to which diff ratio is used.

Every performance shoot out I have seen or read about class vehicles on their engines number of cylinders, engine size, how many wheels are driven or if it has any form of supercharging.

I dunno maybe thier should just be a 'Dark' and 'Light' side????

Hmmm...

I intend to go, and my car is an everyday driver. Underbody exhaust, whisper quiet, 15" rims, the rest is as it comes out of the factory.... what does 'standard' mean?

But I cannot be in Street Class as I have an 8TB setup..

I guess it's a nightmare to manage, but seems to me there needs to be a better way...

I shouldn't worry through, because the closest I will get to the 'tin cups' will be if it trip over them on the way to the bar

Cameron...that could get you into the $hit with the RSPCA.

Some of the stuff they drink down there requires a cat to sit on the can.

We all know why its called XXXX

The structure of classes at the nationals or probably any cobra event will always be a difficult issue. The main problem is that these are all individualy constructed vehicles, and with there being multiple manufacturers of the base car, whom may suggest that certain components, usually taken from production vehicles, be used to complete it, and the individual constructors whom for various reasons may choose to complete it with different components, be it production or after market, does not set a precedent for a "standard" vehicle.

For many years the show n shine classes were debated and the structure continuosly altered to find a happy medium to give some parity between high budget shop built and lower budget home built cars. This debate still continues.

What I think they are trying to achieve this time, is to
open up another class aimed at a lot of the cars built through the '90's with std low output 5ltr or 5ltr gas engines, although with the chev LS engines seemingly qualifying for this class, the parity has again gone out the window.

I also don't believe rim size should be a limiting factor in class grading, as we are now practicaly forced to use larger rims as the availability of a decent 15" street tyre is practically nil. I use Bridgestone RE 710 but they are only available in 255/60, not quite the ideal dimension, but they work quite good on the track and are great in wet weather.

Even though this change will be the cause of more confusion and angst, I think it is good that the organisers are being proactive in trying to keep life in the event and not let it stagnate. They are not unreasonable guys and I think they would welcome input into setting up this class.

Unfortunatly I probably won't be entering this year, but will be there with bells on. See you all there.

XXXX....

Can we have a class for those that are....OVER .05%

Hi Guys ,Long Time no post.
David I think you hit the nail on the head with your description of the class,
Maybe it should be more aptly named Classic class or something similar.
and with that comes the contraversial part..

Classic Cobras have---

15 inch wheels
50-60 series tyres (street only)
ford engines (flame away!)
single carby
No aluminium heads
brakes that fit under 15in wheels

We all know that if you looked at all 80 or so cobras at any given nationals,you would not find one car that could be considered "stock"
The biggest limiting factor to any car on track will be the tyres grip,so what brakes anyones running is going to be limited by this fact.
Anyone can go down the road and buy better brake pads for whatever callipers their running,to deal with extra heat generated.

at the end of the day the nationals are supposed to be a fun event,anyone taking it seriously should run in the more competitive classes anyway,Maybe we could call it the FUN class.
