looking at purchasing wheels...deciding between advan rs and hre comp 97...since comps are 3 piece look smaller, thinking about goin with 20s...will i really feel it compared to my stock 19s while driving....dont track regularly and could use my stocks for that

[Nawaaz]

In my opinion 20's would be purely for looks and may diminish performance. I would stick with 19's if you want the balance of performance and looks.

[golemite]

If you're going to keep your stocks for tracking, get the 20s

[gthirtyfizle]

I did the same.... Went with 20's. 3 pc lightweight forged wheels. Top nothc 360's. U can deff feel the difference with 20's. Even if they r light, that extra inch in diameter makes a big difference, so i went back down to 19's. Car feels much more planted with 19's.

19s FTW!

[david @ eas]

I'd stick with 19"s personally... There are several reasons behind it but most of all I think they look better.

I felt going with 20" COR Monobloc definetly was felt in stopping power. Never took on track but did race around town feeling the difference. The advantage of going aftermarket whether 19" or 20" is the added width.

These are pretty light for being 20"

I say if you take the M3 to the track get 18's or 19's. If your car is a cruiser, 20's seem to look a little better. I have 20's currently, but I do not track my car at all. It is my daily driver.

I have OEM 19s for the track, and strangely, also have OEM 18s.......

The M3 has three sets of wheels/tires
The M Roadster has three sets of wheels/tires
The X5 has two sets of wheels/tires.

I even have a set of wheels/tires for the X6 that hasn't been officially ORDERED yet......

I need help.......

If you are not tracking your car go with 20's. you will regret it later.

Beyond looks, which are subjective, I can't think of ANY reason why anyone would consider 20" wheels. There isn't a single functional improvement to be gained, but many ride/handling qualities to be lost.

Stick with 19.

Looks is a MAJOR part of cars. My 20s weigh less than stock 19s. I notice no difference in handle whatsoever. But then again Im not a race car driver.

I think the 19's look more balanced on the M3, and I can definitely feel a difference between 18s and 19s as far as comfort goes, and would imagine 20's would be even more noticeable.

I think another deciding factor in this argument is sidewall.
With 20s the tire is So freakin thin.

I will have to agree with you on the comfort. I had 18s, 19s and 20s but I have noticed the most difference between 18s to 19s which you feel the difference right away. From 19s to 20s I had to go over a few bumps on purpose to see the comfort level but there is a slight difference.

If your wheels aren't fully forged (which most companies are not, despite the word "Forged" in their company names), they will most definitely be weaker. Not to mention, the location of weight on a 20" wheel is 1/2" greater in diameter, canceling out weight savings. The difference is 3 pounds increased inertia per inch moved away from the center. This also affects how the car steers.

Some people care about these things when making a multiple-thousand dollar decision while others do not. I fall into the group who does care about weight, strength, form, and function rather than form alone.

That being said - I do think that most 20s LOOK better on this car.

I LOVE my 20's

I agree completely. Most who buy a high performance car does so for the performance.

For me, performance always trumps looks, otherwise I wouldn't have gotten a performance car in the first place.

I don't get why one would buy a performance car only to degrade it.

So you do "performance driving" to work and back? Make sure you save that 3lbs per wheel when you pick up the kids from soccer practice. Very important.

With the driving that most of us do 99% of the time, it doesn't make a difference if you have 19's or 20's.

Get 20's and keep a set of stock 18's for the track. Problem solved.
