just bought a set of stupidly light 16" oz wheels, a friend of mine recons that for every kilo you take off the wheel its the eqaulivent of taking out 25 kilos from the car weight. is this bollo(ks or not?

His figures aren't right, but the theory is correct. It's the same idea as lightening the flywheel.
What wheel/weight are they?

i thought as much, they are 5 spoke 205 16" white oz rally wheels, not sure on the make, they bein repowdercoated at the mo, will get them on the scales soon as they are done. ive been through loads of nice wheels, but these take the pi$s for how light they are

Having lighter wheels will always to your advantage.
The whole thoery comes into place when upgrading to a bigger size. The bigger the wheel the more weight is transfered further to the centre of the wheel. Remember physics lessons about weight and pivots
Also note that a 16" tyre is heavier then a 14"
Lighter and bigger wheels at the end of the day will probably net nothing regarding weight reduction/ inertia Vs smaller/haevier wheels.
You will gain a better contact patch (foot print) , better room for a bigger brakes. and more stress on the drivetrain.

ill get some pics up soon as they are done, dont think they make these ones anymore, ive had leggras ages ago these are way lighter
Light wheels are also a great help to aid unsprung weight on the car, as this cant be delt with by the cars suspension.
I am seriously thinking of going down to 15ins wheels for racing next year. I have found a 15ins wheel that just fits over my 310mm discs and Willwood calipers.
Plus the wheel is only 5 kgs. Will be interested to see the weight of your wheels.

Here is a site which contains alot of wheel weights, very helpful, but no pictures

but this site has alot of wheels including their pictures, just cross-reference
