I got the same kit several weeks ago, but haven't installed it yet. I'm waiting to get my bike on the track and run it with stock suspension so I have a good comparison.
I am not a small lad - about 200 in gear. After a day of break-in at the track, I realized that the stock forks are undersprung for my weight/use - I nearly bottomed them out a couple of times.
I also a cheap bastid - I couldn't quite convince myself to go full cartridge for this bike, so decided to go with a spring/emulator kit. Picked up the TD kit yesterday and installed it this morning.
The kit is very similar to that offered by RaceTech for the Ninja 250/300 with some exceptions:
It includes new springs - slightly shorter than stock, but that's to accommodate the emulator.
New damper tubes - much better quality than stock, drilled and surfaced to provide a good seal with emulator.
New preload spacers - aluminum, rather that stock steel.
I've done a number of fork rebuilds and have to say the R3 forks are super easy to service. No fork spring compressor needed. Once forks were off the bike, it took maybe an hour to rebuild both forks. No drama, no tragedies. You do have to completely disassemble the forks to allow removal of the stock damper tube cup, but overall a nice kit that installs easily with basic shop tools.
You will need: 41 mm seal driver, 24 mm socket, 8 mm hex (allen) driver - 4" long or so, and a means to set fork oil levels - that's about it.
