Increasing preload makes the spring more stiff...
spring stiffness does not increase, however, "increasing" or "stiffing" will increase riding height (see setting sag.)
i had my sag set up by some onside suspension guys. they put a ziptie on one of the forks to see how far the forks travel. its about 5 mm from bottoming out. i read online it should be about 10 mm. do you guys think increasing 1/2 turn on the preload should get it pretty close to 10 mm?
Front needs to be turned a bit..try to go full (stiff) and measure and back off till you get there.

Bottoming out should be adjusted by adding more compression, not preload. No matter how much preload you crank into a spring, it doesn't change the spring rate.
heres where im getting some info.

If the forks bottoms out, reset the cable ties and increase preload until the cable tie stops around 10mm above the limit. You should always leave about 10mm travel for emergencies like slamming into uncharted potholes.
If your spring rate is right and your compression damping is where you like it bottoming out is controlled by your oil height, not your spring preload or compression damping; those methods are simply a patch for correct oil height.
Most guys I see on the street have got waaaay to much pre-load dialed in, turning their machines into miserable buckboards. The settings are there for a reason.
adjusting the damping does more to your spring go check out dave moss videos on onthetrottletv.com also feelthetrack.com really need to get it right

Dave's videos help you set your suspension up at the track and bandaid any problems, like adding preload if your bottoming out. I don't think it' exactly how the pro's do it.
