What is an Alloy Wheel?
Until recently, the wheels fitted by most manufacturers to their every-day cars have been "steel wheels" Steel wheels are more resilient to damage, and are considerably cheaper to fit. Unfortunately they are almost always heavier, less attractive and smaller in both diameter and width than alloy wheels.
The term alloy wheels is usually given to wheels 'cast' from a mixture of aluminum which is light weight and great at dissipating heat and small amounts of more rigid metals whose presence in the 'mix' provides rigidity and helps prevent cracks propagating.
What are the benefits of fitting Alloy Wheels to my car?
In general, alloy wheels are lighter, more attractive, and better at dissipating brake heat that their steel counterparts. They tend to be available in standardised sizes which means competition amongst tyre vendors giving low prices and good availability!
Fitting alloy wheels normally reduces your car's unsprung weight - in layman's terms this means a reduction in rotating mass at the ends of your suspension components, giving you improved steering feel and greater braking response.
Where Can I buy Alloy Wheels?
If you're in the USA - we recommend Tire Rack
If you're in the uk - we suggest: Elite Rainham
If you're after a set of second hand wheels - click here for an eBay Wheel Search!
What does Offset mean?
Offset is the distance between the hub mounting face at the back of the wheel and the wheel's centreline.
Offset is usually stamped or engraved into the wheel and is measured in millimetres of 'ET' [ET is the short form of the German word 'Einpresstiefe' which literally translates as 'insertion depth']
Positive Offset wheels have their mounting face toward the front face of the wheel. Most front wheel drive vehicles have positive ET wheels. Eighties and Nineties Volkswagen wheels are usually ET38.
Zero Offset wheels have their mounting face even with the centerline of the wheel and are by definition "ET 0".
Negative Offset wheels have their mounting face toward the rear of the wheel - powerful rear-wheel drive cars often have wheels with negative offset.
What does PCD mean?
PCD stands for 'pitch circle diametre' and is the diametre of a circle drawn through the centre of your wheel's bolt holes. P.C.D. is measured in millimeters and also indicates the number of studs or bolts the wheel will have. Volkswagen Alloy Wheels are usually either 4x100 [i.e. 4 bolt holes drilled through the centre of an imaginary 100mm circle] or 5x100 [VR6s, GTis and MK4s]
What does Centrebore mean?
The 'centerbore' of an alloy wheel is the size of the hole at the back of the wheel which the 'hub' fits into. To help the wheels to seat properly this hole needs to be an exact match to the size of the hub.
Most modern wheels are what's called 'hub-centric' - this means that the hub which protrudes from your car [and mates with the equivalent sized hole at the back of your wheel] is 'load bearing'. All the studs or bolts do therefore is hold the wheel onto the hub!
If you have' lug-centric' wheels, the state of your studs or bolts is obviously more critical - be sure to replace these from time to time and always 3/4 tighten the wheels off the car to ensure they're centred.
What does Plus-Sizing or Up-Stepping mean?
Plus-Sizing or Up-Stepping are two terms given to the practice of increasing the diameter of your wheels whilst simultaneously reducing the profile of your tyres to keep the overall rolling radius the same.
Benefits - Plus-Sizing will improve the handling of your car! - each step will reduce the proportion of flexible tyre 'sidewall' to rigid alloy. This will improve response, will help keep the tyre tread square to the road and will improve your car's 'feedback'. If done properly speedo and odometer accuracy will be retained and the car's sure to look better..
Disadvantages - In the majority of situations, tyre inches are lighter than wheel inches. Plus-sizing can make your overall wheel/tyre package heavier. Reducing the profile of your tyres will also reduce your car's damping deflection under compression [the ride quality will get worse] Other disadvantages can include you needing more expensive tyres, your brakes looking puny and people's grannies laughing and calling your car a pram.
Fitting Alloy Wheels...
Before you do anything, check to see that you the right sort of bolts - Bolts and studs have various diameters, threads and seatings, your wheel supplier should be able to advise on this. Also check to see that you the 4 plastic spigot rings which help the interface between the wheel and the hub.
Next you need to jack your car up - do this securely and be sure to use axle stands, chock wheels still in contact with the ground and apply the parking brake. Offer a wheel up to the car and check that the bolt holes line up, that the wheel locates on the hub correctly and that there is wheel arch, suspension strut and brake caliper clearance [if you have upgraded your brakes be SURE to seek advice and measure everything thoroughly BEFORE you order!].
The wheel bolts or nuts must be tightened to the manufacturer’s specified torque. [Be sure to re-torque the after a 100 miles or so as they will compress slightly] tighten them progressively 'till they're 3/4 tight then lower the car and complete the process.
Alloy Wheel Care
As anybody who's stepped into a motor factors in the last 10 years will tell you, there's a huge variety of specialist wheel cleaners on the market, all designed to help make the job of cleaning your new rims that little bit easier, unfortunately the real key to a great finish is hard work.
Before you fit your wheels, give them several coats of good quality car polish back and front. This will help prevent the road salt, brake dust and dirt 'keying' to the surface on first use. Be sure to treat the surface of your alloys as well, if not better, than you would your paintwork. Remember, you've spent a small fortune of your alloys and they're going to be subject to the harshest conditions of just about any part of the car!
Frequent washing with mildly soapy warm water [having hosed all the loose abrasive grit off first] is the best way to keep wheels clean. Never use abrasive cleansers, electric buffers or wire wool pads on your wheels. Where possible let your wheels cool thoroughly before cleaning them and avoid car-wash wheel-cleaners at all times.
Here at Matey-Matey we're huge fans of deep-dish wheels with diamond-turned rims. If you've opted for diamond rims, there's a good possibility these will NOT have a lacquer coat on the rims and this is going to mean lots of polish and elbow-grease to keep the finish looking good.
Final Top-Tip - Fast Road and Track Driving can cause your wheels to get VERY hot indeed. Their proximity and direct connection to the braking system makes heat transfer a very real problem. Hyper heating the wheels can irreversibly change the colour of the paint on your wheels and as they heat they can expand to the point where your expensive centre caps are no longer held in-place and break for freedom. We know. We've had a set of silver wheels turn bronze and throw all 4 centre caps in just 1 hour on track!

Immigration -1 (Ref- Amin Rahman MARN 0322761)
Hello ,
Recently some changes to Australian skilled migration system have been announced. You will find details on our website http://www.ozma.org
Outlines of changes are:
Processing Priority
1. - an application with a nominated occupation, which is NOT on the MODL (migration Occupation in Demad List) will be in the processing queue no 5.
2. - applications whose nominated occupation is on the MODL will be in the processing queue no. 4
3. - applications whose nominated occupation is on the CSL (Critical Skill List) will be in processing queue no. 3
4. - applicants who have managed to get sponsorship from a state, their applications will be in processing queue no. 2
5. - if any applicant is nominated by an employer then their application will be in processing queue no. 1
Nobody can say at the moment how long it will take for an application in queue 4 or 5 will be processed . Currently DIAC is only looking at processing queues 1, 2 and 3.
Annual migration intake
has been reduced to 115,000 per year - a reduction of 14% from the previous year.
Suggestion
Prospective applicants, instead of falling in queue no 4 or 5, where they do not know when their application will be assigned a case officer, should try to fall either
in queue no., 2 by applying for a state sponsorship OR
in queue no. 3 by preparing for an occupation which is in the CSL
Note: The CSL has just been updated (17/3/2009).

Zodiac & Birthday Profile Checks.
Your personal ruling planets are Sun and Mars.
There's no way Mars will allow you to be under the rule or control of anyone else. You are independent, straight forward and enterprising in your manner. An explosive nature is revealed at times when restraint or opposition is placed in your path. You must expect danger at some stage of life as Mars rules weapons, injuries and fights.
Always prefer the gentle response to the aggressive, to minimise the negative energies of Mars. The sub rulership of Saturn means you do have the capacity for restraint if you exercise cool headedness instead.
Your lucky colours are red, maroon and scarlet and autumn tones.
Your lucky gems are red coral and garnet.
Your lucky days of the week are Monday, Tuesday and Thursday.
Your lucky numbers and years of important change are 9, 18, 27, 36. 45, 54, 63, 72.
Famous people born on your birthday include Shelley Winters, Robert Redford, Patrick Swayze, Christian Slater, Madeleine Stowe and Edward Norton.
This is a sample of the full reports available from the Soul Shop
