So apparently (according to a reputable wheel retailer)
Quote:
reducing 2kg overall wheel weight offers the same straight line performance equivalent as removing 20kg from the car

The x10 is a rule of thumb when working out inertia/rotating mass/energy consumption, etc for wheel weights. (Much like why lightened flywheels offer such good performance increases)

Who has lightweight wheels on there car, and did you notice any differences in performance?

You can work out the maths with how insanely effective a set of proper light weight wheels could improve performance if the above is as true as it apparently is.

I'm going to do more investigation.

Fancied a set for the RS but never knew if it was over hyped and would only come into effect for dedicated track cars :?

Would like to know the truth :D

I know people who have lightweight wheels and they have noticed a difference from before and after.

Really, you would need to see this kind of test done over say a quarter mile with 0-60 timings ect down the strip done on an average of 3 or so goes on each different wheel type.

I think my friend steven or mark had lightweight wheels on his teg, ill ask them and find out and see what they thought of them if they did :)

Dan would be good to ask, he has Enkei Lightweight wheels as standard on the Ignis and hes just put run of the mill alloys on.

I noticed a difference going to from my old heavy wheels to my Pro race 3's :) Mainly on the initial acceleration, but not so once moving :)

:thumbsup: That's what we like to hear! 8-)

Only issue with my wheels is that they are quite light as it is for 15" Enkei OEM wheels, but it was more a fact that some other 15" wheels may be slightly heavier than mine but provide better brake clearance so it was weighing up the pros and cons.

My friend steven had standard wheels on his car, mark said he had some lightweight wheels, he said he did notice a small difference on acceleration but that was mainly it.

Probably a question for the DC2 forums :) they will give you a good answer im sure and its more related to your car too. Im sure with boost it wont matter though :lol:

Yeah most people put Rota Slipstreams on the Dc2's for weight purposes as they are a very lightweight 15" and 16" wheel for a good price.

With boost it won't bother me too much as traction in 1st and 2nd will always be an issue on 15" alloys, but useful for all to know as I know Dc2's are heavier than fiesta's, but even saving say 40KG of inertia weight would make a HUGE difference on any car!

Of course upgrading to a better more lightweight brake system will also help with unsprung weight so another thing to keep in mind, but that's off topic!

i think the wheels on your teg are the same as my ignis but wider.

mine are 15X5J and they weigh only 5.5kgs per wheel.

if i was you i`d find out how much yours weigh so you know when your looking for new wheels.

i was looking a those rota slipstreams for the ignis in 15x7J they are 5.4kgs per wheel.

When i stuck the 17s on mine temporarily i only had them on there for a week so didnt drive it much and they wernt my wheels so didnt go hammering about on them but it definately wasnt as responsive/quick with them on. but then again that could be down to the fact the rolling diameter is much larger on a 205 40 17 tyre than a 185 55 15.
