  1. I guys, im in the market for an Aurion in the coming months after i buy my house

    and just wondering what your thoughts are buying a new Aurion based on the current Fuel Prices.

    everyone says its bound to go up even further, and i dont want to spend most of my money on Petrol.

    the other draw back is if petrol continues to rise will the value of the Aurion keep coming down because less people would want to drive V6...

    so my dilema is should i buy V6 or go for a smaller car...although i need the space for Pram, shopping daily routines.

    If you are getting new or new-ish.. look into a Novated Lease even if you can afford it outright... everything gets taken out pre-tax.. insurance, rego, maintenance, petrol...

  2. the above physics is also the reason i prefer FWD over RWD...

    FWD from factory is designed to understeer for n00bs but with FWD, you have the option of creating more/less under/oversteer through minor suspension tweaks...

    I like FWD becasue of the option of control it gives me as a driver depending on situation. I do not have an Aurion YET, but with all it's traction/safety features drivability will be very manageable.

    RWD on the other will always oversteer and is ahrd to get it to understeer unless you have a severely crap selection of tyres... 'drifiting' and letting the wheels skid/bounce on a surface is the rwd method of managing over/understeer..

    example on FWD, if you oversteer, you step on brake to reduce it... on RWD, you step on your brakes during oversteer and your dead... you have to let it 'drift'.. this is why n00bs ALWAYS hit poles...

    on a side note of hitting poles, for those who know of Anthony Robbins, what he said in one of his seminars was correct and is what they also teach you in motorsport... if your about to hit something you will always hit it... if you know your about to hit a certain object.. LOOK to where you need to be. It explains why RWD drivers ALWAYS oversteer the rear side of their cars into a pole

  3. isnt toe when the wheels at the front edge are either adjusted in or out to prevent them from scrubbing or pushing and to run reasonably square to the car/steering.

    I thought camber might have somethin to do with it thinking that the tyres are on a lesser surface area therefore creating the slightly erractic steering and less road holding of the car.

    I had a quick read up on it and both appear to have an affect on the steering and road holding of the car prob a good idea to get both checked then

    most people ask for a "wheel alignment" which to most tyre shops and dealers is just the steering wheel in relation to the wheels so really paying for no change, i usally get some sort of readout on it and try and watch what they do but i try to use the more "technical terms" when explaining it so the fella might get more of an understanding of what im after.

    hey mate,

    you are correct that it is all detrimental.

    CAMBER

    Is used to correct tyre wear... when a car is lowered the wheels shift vertically off the control arm/hub.. as in the top of the wheel goes further in the arch and the bottom of the wheel goes outwards hence why severely lowered rice cars get massive inside tyre wear. This causes reduced tyre footprint against the road. A bit of negative camber is OK your wheels generally goes positive on turn ins... this is where CASTOR comes in...

    CASTOR

    is a way of DYNAMICALLY shifting camber. Adding some sort of CASTOR devices changes your camber to certain degrees dependent on wheel turn in.

    An example of this in motorsport is the following scenario.

    - You don't want too much camber to prolong tyre life on cruising so you adjust for -1.5 static camber at the front.

    - on incline/decline turn in, optimally you may want to have you car doing -2.5 or -3 as during turn the tyres maybe flatter on te road surface during said incline/decline

    - CASTOR is a compromise in that its like a mathematical exponent... static camber stays as -1.5 when cruising straight, but the moment you turn in camber shifts to -2.5

    TOE

    you may have all heard of the term TOE IN or TOE out. it is simply that... think of you feet... when your toes are in, it points your feet inwards, and opposite when out. when your car is generally turning to the left automatically it maybe because the left front wheel suffered toe out misalignment as a result of very spririted driving.

    CAMBER/CASTOR will NOT cause your car to turn into a direction, it is simply a function of TOE.

    But you guys are right, most vehicles even performance/sports ones do not come with camber/castor adjustability from factory hence the aftermarket parts available. TOE is adjustable on any car and is the only thing correctable when you take your car for wheel alignment. it is adjusted through a shaft that connects the hub to the steering rack.

    Most people who pay the ~$70 to get an alignment are wasting money.. someone coming in asking for "an alignment" doesn;t sound very knowledgable and very easy to scam money from. WHEN you do go for an alignment, be specific as to what you require and ALWAYS ask for a before/after printout of their laser calibration. Be specific when you ask for an alignment... I want this much toe and this much camber, etc....

    Hope that helps...

  4. yep a proper test is a flat road like a highway/motorway with tyre pressures all round.

    camber won't fix this issue.. it's TOE that need adjusting. but AFAIK no car comes factory set at 0/0.. whenever i get my cars aligned at tyre sussy shops i always ask for 0/0 Toe and -1.5 camber front and -1 rear.

    ALWAYS ask for a before and after printout of alignment...
