Getting a Cams licence is not at all difficult. You need a car club licence (pick one they are cheap) & then send CAMS a cheque for less than a hundred dollars with their form. If you want one for a day you can organise that too. Simply put the threshold for money/forms/competence for doing a track day with a club is so low that there is no reasonable excuse - none at all - to do something stupid instead. It is not the money, it is not the skill level required, it is not the time required. It is simply that people cannot be bothered doing something they incorrectly perceive as being too hard. That being the case there is no reason to link motor sport to anything that happens on the roads. There are countless numbers of resourceful, competent and dedicated people who work tirelessly to organise & participate in motorsport all around the country. The more people try & link tragic accidents like this to the sport the harder their job becomes. So stop it. If you want something to do go down the park & kick a football. It works just as well in stopping people from having accidents in their cars. Oh and one last thing. It is government money that has, to a large degree, allowed the expansion of the Collie motorplex & that will allow for further expansion in the future. It is also government money that hopefully will allow Wanneroo to expand. So just think before you tip a bucket of sh!t onto the pollies for doing nothing.

In the same manner as there being no time & place on a public road there is no reason to link such unfortunate occurances to motor sport or motor sport facilities. At all.

Let me guess you are running castor rods with a rod ends rather than bushes and the outer upper suspension link bush is lasting next to no time at all?

Here are a couple of photos are are tenuously related tot his thread.

Well I would like to see Ari Vatanen over Mosely. Maybe that way the WRC would get looked after properly instead of being permanantly fkd about. He is already a politician so doubtless will be familair with the back stabbings etc. Hard to see how he could do any worse than Max has done these last few years.

The good thing about Webber is he doesn't carry on like a bitching school girl when someone else does it to him. He is an (overly) aggressive driver at times but to give him his due, when someone else does it to him he just gets on with it. As for the rules - it is F1 - the rules are whatever they make up this week. Just went to down to the news agent. Usually they have a half a dozen or so copies of Auto Fiction. This week there are atleast two dozen. I reckon someone thinks there may be a Webber induced sales bump.

Well said. Schumacher was the one who started all the swerving off the startline to push others out of the way. It has only got worse since. Hopefully Webber will learn from this & not do it again.

Yeah - wastegates & wastegate actuators are not the same thing.

Most Blitz rims have the size, offset, manufacture date etc cast into them on the inside of the hub. Take the wheel off & have a look. Are you happy with the size/offset of the rims you have? Remember the calliper clearance is not related to the offset. I have a set of Blitz rims that only just clear the front callipers on my GT-R. The Volk CE28's I also have clear them by a good half an inch in all directions. The rims are the same size & the same offset ie 17*9 +22. So changing the offset is not the key to fixing the problem. See this for sizing. http://www.nismo.co.jp/en/products/competi...pdf/wheel02.pdf

It would help if you stated what the offset is. There are two issues. 1. Getting enough room between the calliper & the spokes of the rim. This has nothing much to do with the offset. 2. Getting the offset right. From memory a number of about +12 is ok for a R33 gt-r (not sure) but you need also take into account rim width, tyre width, suspension camber. Basically offset is all about how much of the cars track width the rim provides. A smaller number givers you a rim that sticks further out into guard which is a bit upside down but there it is.

My Cusco castor rods aren't bent. What they do instead is slightly offset the position of the rod end at the front of the castor rod.

Then try Nisswreck

There are a number of reasons 1. Cold fuel is more dense. 2. Hot fuel will vaporize. 3. The cars dump a massive amount of heat into everything. Historically cooling the fuel was at its most important when the cars were limited to 150 litres for a grandprix. This was in 1988 for the turbo cars from memory. The extra few % of fuel gained was invaluable. Presently you are only allowed to cool the fuel so many degrees below ambient. This is what BMW got in trouble about at the Brazillian GP a couple of years ago. All pumps are affected by the temperatures of the fluid passing through them. All pumps heat up the fluid they are pumping - the most pronounced example of that being your turbo. As an aside if you think of the 20000+rpm the F1 motors used to run at then you can get an idea of the tiny period of time the injector has available to deliver fuel to the motor. To help in this regard the pressures run in the fueling system in the F1 cars are, by comparisiion to road cars, massive. Yes but there is nothing much you can do about it other than increase the efficiency of the fuel pump or lower the rail pressure. Broadly - the hotter the fuel the more prone you are to having pumping issues & vapourisation issues. Also a cooling inlet temp can allow more ignition advance giving more powah. Some fuels have a marked cooling effect on the inlet system. Alchohol based fuels particularly. The old turbocharged indy cars did not need to run intercoolers simply because of the fuel they used.

Well firstly, thanks for the appraisal of my experience. Yes I well understand what people are aiming for when experimenting with different gases in their tyres. Simply put you are after a gas that shows little change in pressure for a given heat input. There is next to no difference between air & nitrogen in this regard. Which was my point. As for the gas damaging the inside of the tyre - no race tyre I have ever used has died of old age. They either A. Get punctured/flat spotted/damaged in the side walls from saw toothed edged kerbs. B. Get heat cycled too many times or over heated & lose their grip, ie go off. C. Get worn out. The life of a race tyre is short & ugly. No one I have ever met cared less about the insides being subject to chemical attack. In any case when you go to a track you change the tyre pressures regularly. So unless you bring your own nitrogen you are wasting your time.

Unfortunately the demise of the straight six is less to do with the motor itself & more to do with making the car easier to design for frontal impacts.

Yeah that is pretty much what I did.

Yeah its Wanneroo so clockwise. Only four serious corners, three right handers - 2 x 180 degree & 1 x 90 & one left hander (90 degrees plus a little). Plus a few less substantial wiggles. Give me a break (please). It was cold, it was wet, I was tired, out of practice and err, um refer to the driver's book of excuses for further info.. Oh and it was the long track and none of the other AWD's managed to go any quicker on the day.

Adjustability is all good up to a point. The point being you cannot adjust a Whiteline bar to be as stiff as a Cusco one. So you need to have a good think about what rates you run rather than just pick a bar because it is cheap etc. Actually does anyone have the diameters (internal & external) for the Nismo bars???

Well brand association can work - but only up to a point. I would suggest that the link between what Toyota sells on the car lot & F1 is too tenuous to be useful. On the other hand rallying (the sport Toyota gave up to go into F1) has done wonders for any number of manufacturers - Ford, Subaru, Mitsubishi, Citroen, Lancia.....

To answer some of the various questions: Sort of one of those things - you either know someone with one who uses it for work or you can't get them. I was pretty happy with the fronts to be honest. Did you just call me a tool? Just used it the once (it rained later) to check that the settings were about right. I am reasonably confident they were.

Yes I am by that stage (past the marshals post) - I also changed the shot for you.

As I said RE55's work fine on a wet track. Here is a photo taken by BNR#@ on the weekend illustrating the point.

As the title says here are some shots of my tyres after fours laps of Wanneroo last weekend. Should be pretty self explanatory. Car is an old R32 Gt-R. Laps time was nothing special (65 second laps) and the track was cold & a little greasy. Thought they may amuse someone.

Unless there is standing water ie puddles on the track you will be miles infront with the RE55's.

Actually the issue is different to what you have described. Take the case any random team. At present they can spend as much as they can get. If the business is profitable at those expenditure elvels then a budget cap will simply remove a very large amount of the worth of the company. How are they going to slug sponsors if the same sponsors know they can only spend $100 million a year, for example? The other issue is how do you price a component made in house. You can't go down to Woolworths & get a price check from isle 5 for a secondary circuit bypass valve CNC machined from the heart of a solid forging of unobtainium, now can you?
