I personally don't like the forged wheel look. Will be trying for something lighter and personally more appealing. I would be willing to spend money for integrity since roads here are beat up by climate changes. We can go from -15 in winter to 95 in summer...reaks havoc on roadways here.

Where can we get these team dynamics wheels? I intentionally didn't get the forged wheels because I figured for $1400 I can get a pretty light set to run in the summer. 2 pounds might not make a big difference but another 7 pounds on top of that I think will make a big difference.

From me . Do you have a particular wheel in mind?

How many people in this tread have ever been on track? Been on track with a different wheel setup? Slicks?

I've been on track a bit.

40 track days last year alone. 6 so far this year. Several different cars, tires and wheels. I spend considerable time in the right seat of many different cars too.

Jim do you work for Chin? If so I'm sure you've run across my buddy Luke McGrew?

Technically I'm a volunteer. I work for track time, beer, food and the love of the hobby.

I may have run across Luke. The name sounds familiar but I don't remember him specifically.

He's an instructor with them. Usually VIR, NCM, MO, ... Black TA Viper....soon to be Black ACR as soon as the build is complete.

Big wheels are "stylish". *yawn* And heavy. I'm disappointed 19"s are the only offerings aside from the winter package. With a car of this size and weight 17"s would be more appropriate performance wise. If I go with (find?) an RS I may very well fit a similar 17" or possibly an 18" package onto it.

My 2004 WRX summer shoes: 17" x 8" OZ Alleggerita with Michelin Pilot Super Sport 225/45/17. The wheels are 15.5 pounds and the tires are 22. What's the use of 350/350 at the flywheel if heavy shoes unnecessarily diminish that?

Everyday driving will definitely see a benifit from lighter wheels. In addition to having everything that benifits the car on the race track, the engine won't have to work as hard to turn those massive boat anchors. So in turn it will be more efficient and get even better gas mileage. If the stock cast wheels were down sized and Forged, that would be a weight savings of nearly 10 pounds per corner. Factor in that it is rotational mass, that 40 pounds turns into nearly a full grown persons weight being shaved off the car.

what is the pay back mileage on changing wheels- I have stock and 44,000 with tax etc for a Focus is definetly on the CUSP

Small. Probably negligible. You may be able to notice an improvement in city driving but highway mileage will not change. There are quick forumlas to guess what the equivalent spring weight savings would be, but the end result is that your wheels would have to be a lot lighter around the rim for it to have an effect on efficiency.

But that's not the only reason to get smaller/lighter wheels.

On my 2010 Mazds 3, I went from stock 17's (23lbs) to a set of 17" Kosei K-1s (15lbs and an inch wider) and picked up about 1.5 mpg. So I would assum it would be about the same for the RS going from cast 19s to Forged 18s.

 

[133trackdog]

What about this idea??? TSW rims 18x8 with Mich PScup2's 245x40/18 will be approximately 40.6lbs per corner vs ford rs forged@ 46lbs per corner. 20 quick lbs where it counts. I went with stock wheels and will get aftermarket for Sebring days. Tire Rack has these tires with the 18s @ $59 less than the 19s..... also FW my choice narrowly over SG.

 

[JahjaMan]

So... fifteen52 Tarmac wheels, 19x8.5 ET40 will weight in at 33lbs per rim. That's 15kg per wheel.
Which is heavier than standard (12.75kg) and heavier than forged (11.65kg) and much heavier than the OZ Leggera (9.95kg).

But they look so gooooooooooooooooood.

I'm torn.

Anyone care to comment?

Buy wheels that don't suck?

Those wheels are atrocious and you should be ashamed.

You asked for a comment...

 

[Maz]

Anyone care to comment?

Sorry mate - IMHO they suck.

 

[JahjaMan]

Lol don't apologise, I know some like them, others hate. But personally, I think they suit the focus body quite nicely.

Checkout my sweet rims guyz I know it's a little heavy but yellow is my favorite color.

Lol sorry Jahjaman I'm just messing with you. If you like them, then all the power to you. They're pretty heavy, you may or may not notice a difference in handling depending on your driving.

An extreme example is the GT350R vs non-R wheels.

Do the Shelby GT350R?s Carbon-Fiber Wheels Help Performance? ? Feature ? Car and Driver | Car and Driver Blog

This is so horribly unscientific. There is no data here supporting lighter wheels being faster. The cup2's have more grip... I know they did rolling starts, but you don't need wheel-spin to see grip differences. Think cornering. One can corner much faster than the other without tire squeal to to compound advantages. And then they go to discuss all the upgrades the R has in suspension (presumably resulting in more grip as it is stiffer). It is not apples to apples and there are too many variables changing.

They should have matched rubber, or swapped wheels/tires between each car and compared runs with each wheel. That would at least help eliminate some of the car differences from the equation.

Not saying lighter wheels do not help (they do), but the article sadly proves nothing.

You are 100%correct. That is why Porsche Uses Magnesium wheels. And CNC's the round into lobes for differential, etc, etc. It will make a difference you can feel if you apply that kind of engineering to EVERY Single part that you can that rotates. That is why they spend the money to do so. It works!

 

[Alwayswantedone!]

While 2lbs at each corner wont' make much difference for handling, but the biggest gain will be in braking and acceleration. 2lbs makes a difference, not a huge one, but measurable. 5lbs at each corner would be massive. Remember this is rotating weight, not just unsprung, or even static weight.

The original author stated 10 pounds per corner. That would be a lot. Magnesium are like 17#, saving 10# per corner
