Here we go!

Please post pics and provide some feedback once you have pulled the trigger.

I shall. I changed the spec slightly. Should arrive around Thanksgiving.

I personally prefer an 18” front and rear wheel size. I’m running HRE R43 Fall-Line wheels F 18x9.5et21 with 275/35 and R 18x10et17 with 285/35.

I don't at all. 18" rears look like Sprinter van wheels to me.

19/20, but y'all get the idea.

20” wheels have a much higher mass MOI and, therefore, rob horsepower and torque to the wheels. Perhaps great for aesthetics but not performance.

What? I’m going 18/19.

Pretend he said 19".

Just like he pretended to read 20

Thanks!

It was a mistake but I guess you haven’t ever made one, correct? If you start off with the first diameter listed incorrectly then it’s obvious the second diameter also will be listed incorrectly. 18”/19” is the correct diameter stagger.

Sure, an 18” non-staggered wheel diameters makes the rear look like a “Sprinter van” Personally, I’ll take function over form any day even if it looks like a “Sprinter van”…Same principle applies to a 19” rear wheel which has a higher mass & mass MOI, especially if it’s a two or three piece wheel design, and more tire mass & mass MOI as a result of being placed at the outer radius. This means there’s more parasitic mass and mass MOI to linearly and rotationally accelerate/decelerate which reduces the torque and hp that reaches the ground. The s65 has a relatively low flat torque output vs. rpm so it’s something you can clearly feel. My ‘00 ap1 s2000 with the f20c had 16” wheels and my ‘05 ap2 s2000 with the f22c had 17” wheels. Any torque advantage the NA 2.2 L 8.2k redline engine had over the NA 2.0 L 9k rpm redline engine was negated by the use of 17” wheels with wider rear tires. Replacing the stock 17” wheels with 17” Volk CE28N wheels recovered enough lost torque to be felt during daily driving and out on track.
