USDM cars have clutch interlocks. Meaning you need to push the clutch to start the car. You'd want to bypass that with a thumb operated switch.

You install a momentary switch that you can push. Then you start the car. That way, you don't have to push the clutch pedal down to start it.
The first vehicle I saw locally with a clutch interlock (push pedal down to start) was an old Hyundai Accent...
I read on this forum of USDM guys experiencing crank walk horrors as a result of the interlock...or perhaps some other factors around that feature. "Idiot proof" feature to prevent the odd pushing start button while the car is in gear lol.

A switch sounds like a better, cooler option actually.

I'm glad to hear this. I'd be keen on that setup down the line. Like B Serious said the pedal will travel up faster instead of slower, does it travel up faster than stock? I've got an AP1 which already has a light flywheel

I'm went with the 8lbs ACT prolite flywheel because lighter is better and I don't have any regrets, it's a perfect setup
that's pretty light dude! Is our stock flywheel 14 or 11lb? How does the car feel pulling up the odd steep-ish incline if you ever encounter those?

Stock is around 14lbs. You might need a couple of starts to adjust but after that there is no problem.
I don't even got a idle control valve so it's way more sensitive because of that but still no big deal.
On last car inspection the lady that had to drive my car did stall it 4 or 5 times though

No IACV - how does this work and why?

AP1 Stock is 14lbs but AP2 is like 22lbs. I debated between the lighter ACT flywheel and went with the 11lbs and am happy with it. I mean I took 11 lbs off the car just by doing that. Like I said the ACT PP feels a little different from stock but I can't say it feels drastically different from OEM. A little heavier and I suppose it comes up faster but you get used to it pretty fast. I still have to put my AP1 slave cylinder on and the spoon braided clutch line I have. Might tackle that this weekend.

OEM clutch pedal feel varies greatly from car to car because of the grease drying up and disc/PP wear (and/or other factors as well?)... I've seen a huge range of pedal feel from different s2000's factory clutches

My OEM clutch pedal feel was in the middle of that range that I've seen and my ACT PP feels the same as my OEM did
