i think so too.Quote:

yep, all very valid points here people
thats why i intend to go down to 15' and it should be okay for me, esp. on crappy sydney roads :D
having said what i said before,
just say u are putting 10 inch wheels on a lamborghini its not going to be faster.
to a certain degree I think wheel size to performance also has a lot to do with the torque of the engine.
but i guess smaller wheels are better for handling?
big wheels good for drags (in relation to the amount of torque)
Yes, they are right. Most of drag racing use 14"-15" rims.
drag uses small rims
with GIANT FAT wheels though
nope, larger wheels on low profile rubber better handlingQuote:

i have 17"s and they arent heavy.. they weight in like about 8KG each wheel.. my old wheels.. also 17" were 10KG each wheel... but yes... it does make a difference..
its not just the weight of the wheel though. as mentioned earlier its the distribution of the weight. if you did high school physics you'll remember a formula ( cant remember exactly) which is used to calculate the work required to move something. i'm sure someone on here does some more advanced physics and can clarify on this. but anyway, the greater the distance of the mass to away from the fulcrum, in this case the centre of the wheel, the more work is required to move it. so, larger wheels have more weight distributed further away from the centre and therefore require more energy to rotate them.
Drag cars use larger tyres so they can run a larger contact patch on the road. All of the wheel and tyre weight doesn't mean a thing in the world if you can't get power to the ground. Mind you, serious drag car run lightweight wheels and lightweight brakes.
Race cars use larger wheels so they can use larger brakes, and lower profile tyres mean stiffer sidewalls, which means less tyre flex, which means more control and grip when turning.
Running larger wheels means your car will make less power at the wheels, but this may be irrelevant if the car makes a lot of power. Wheel selection is a compromise between power and handling.
For racing: 17" is too big.
For street: 17" is very sweet.
Depends on what you think!!
you'll prob find that going anything over 2 sizes from what is factory will tend to drag the car down abit. Like all above stated the rims will lag you depending on torque and the car's performance. From factory they make the cars with the rims for a reason, namely they are cheap and perform better with the standard wheels.
Also if you get lighter wheels you gotta be careful as they are made with alloy and are easily warped due to the large potholes in Sydney!
(i've got a set with the same prob) :(
Problem with steelies is that they are quite weak compared to forged/cast aftermarket rims. Expect steelies to bend/warp under track use!Quote:
