Get some track tires in 18" on some wide and light wheels and you'll see that this will make you several seconds per lap faster.
the other parts will never improve your laptimes as much as a good pair of shoes.
I 50% disagree. At the end of a typical north american 20 minute HPDE session...you are pretty tired from hanging on for dear life. So harnesses made a HUGE difference.

Not to mention how you feel at the end of the day. OEM Belts - sore knees, sides bruised, and tired shoulder muscles. Harnesses - great...laughing at the guy with OEM belts. I have a lot more confidence in my E90 with harnesses and drive a lot better. As you add more grip, the beat up sensation will only get worse.

I also 50% agree because tires do make a very noticable and significant difference.
