Regarding cutting the steerer tube. Are you sure your old set-up is threadless? If it is you're o.k. If it was/is threaded then you'll need a new headset and stem.
Assuming you've got a threadless, the only confusion I saw was regarding cutting the steerer 3 mm below the stem. I would clarify that and say cut 3 mm below the top of the stem. An easier way to do it, is to use the spacers to find the proper height of the stem, then remove the stem, add another spacer, replace the stem and mark the steerer flush with the top of the stem. Viola! When you cut it, it'll be recessed into the stem!
Oh Yeah remember. Measure twice - Cut once!

one last thing...make sure you file the freshly cut steerer smooth and blow out all the shavings...

A good rule of thumb I was taught is 20mm either way won't change 'much' on a bikes geometry and t should handle it. I went from 100 to 130 and my steering improved but I also made some other changes to my stem to adjust the height and length of my cockpit for me.

Honestly for me i have a gary fisher mamba 29er and switched to 100mm rockshox RL solo and I love the fork. Bike came with rockshox dart 3 and those were horrible however I did feel more confident letting go of my handlebars when i had the 80mm fork. Now it's a bit weird to steer and I definitely noticed a difference in handling. I may go back to 80mm forks just because the bike feels weird. Too bad this was not a cheap fork lol and i'm going to have to take the L on it. Also I realize this is a 17 year old post lol but I just had to say something =)

I'm restoring an older bike (rim brake) that has only 63mm of travel. Would like to go with Rockshox 80mm fork, but only rim brake can find is a 100mm Silver TK solo air. Question - Can this fork be converted to 80mm travel ? I know years ago my LBS was able to convert a 100mm SID to 80mm by changing just the spacers. Appreciate any ideas/comments.
