Apex Arc8 wheels to e46 m3

Fr = μN

where:

•Fr is the resistive force of friction
•μ is the coefficient of friction for the two surfaces (Greek letter "mu")
•N is the normal or perpendicular force pushing the two objects together
•μN is μ times N
Fr and N are measured in units of force, which are pounds or newtons. μ is a number between 0 (zero) and ∞ (infinity).

I'll explain a little better when I can get to my school notes. As you can see though, there is no varible for surface area or contact patch. It's the extra weight of the wider wheel/tire combo that gets you the extra traction.

high school / GE lower div college level physics dont explain much in the real world.
Even grad level dynamics courses only explain the behavior of nothing more than simplified models..

Long story short, your coefficient of friction isn't simply a static number, and does depends on overall contact patch area.

I like how this turned from a pchop to a physics lecture.

^oops wrong one. I'll grab my physics stuff at school tomorrow and post up the formulas.

^^ thats for static friction. I think area plays a role in kinetic friction, but im a little dusty in the physics department. I do remember that the coefficient of friction M= force of friction/ normal force, where the normal force is just mass in kilograms x acceleration from gravity (9.8m/s/s). I cant remember if there was any specific formula other than that ^^ to solve for the force of friction, and cant remember much about kinetic friction.

no it's not. I learned about traction and such in physics and area of contact isn't even in the formula.

Than explain. Because I calculate, the tires have about 6-8 (ill say 7) inches of contact in y direction and 8-10 inches in x depending on width of tire.
7x8x4= 224 inches squared of contact area for all tires.
7x10x4= 280 inches
280-224= 56
64 was a close estimate.
Of course, I am basing this assumption off the idea that
More area = more traction. << Is that not true?
But yes I want the arcs because they look awesome as well.

[325ix]

lol I don't think that's how it works...

arc's look sweetest.

[yberther]

I wanted to get csl styled wheels with more traction than the stock ones. The stock ones are 8 inches and arc8's are 9.5-10 inches. Thats like 64 square inches of contact difference.

I'd just go with CSL/ZCP wheels or replicas, I think they make reps that are a bit wider if you're so keen on it.

If you go through all this trouble to find wider wheels, you had better not try and stretch some 225s on them.

I found some replicas on ebay for like 700 bucks for all 4 wheels, but im not sure of the quality of the wheels.
And I would never stretch tires on an m3. NEVER

The VMR Reps are cast and heavier then the oem wheels. The ARC-8 wheels are flow-formed, light-weight, and VIA tested/certified in Japan.

I don't have a photo of a silver M3 running our black M3 fitment ARC-8's but on our facebook fan page you can see a bunch of combinations of vehicles and wheel colors

I love the way your wheels look. I will definitely put apex on the top of my list for now.

[Bishop]

Hyper silver is probably as close as you're going to get... Or, OP if you like the color of my Apex's, it's the hyper black.. I love the color

[325ix]

I think the apexs would look good in the stock color.

Here's a picture of an E46 running the black wheels. The car behind it is running the silver ARC-'s




Here's a while car running the black wheels.
