Actually, Rob is the Mid-Central parts vendor. Turn One Racing is the Midwest support team, and we are also Traxxion authorized sales and service, as well as GP Suspension, Penske, Ohlins, etc...
As far as installing the AKs yourself, it can be done, but only with the right tools, the right temperament, and good technique.
I would personally recommend most people pay the $170 in labor to have the job done right by an industry professional, who already owns the tools, has the skills, and the experience, to do the job properly.
If you're one of the few truly mechanically inclined, meticulous, detail oriented, serious do-it-yourselfers who's willing to spend the money to buy fork seal drivers, proper spring compressor tools, etc. and wants to spend the time and money to see if they can do it themselves, then by all means take a shot, but be prepared to make some mistakes, and quite possibly have to do it again. Hopefully not learning the hard way.
If it were me, I'd be more inclined to try my hand at something that couldn't compromise my safety or the quality of my tracktime if I got it wrong (like painting my own bodywork)
It's really one of those things that's most often best left to the professionals. There are lots of other projects you can do on your own bike that only require normal tools, and that if you get wrong are more of an inconvenience than anything else.
Either way, best of luck with whatever you decide, and of course my personal recommendation is Turn One Racing, I hear they're all that and a bag of chips
