Yeah, DIY. Installation is pretty easy, I only snapped one LCA bolt and I got a genuine replacement from my local Honda dealer for $21. Heres pretty much the procedure just to give you an idea on what youre getting into.
Front: Unbolt the brake line, unbolt 2 shock fork bolts, unbolt the long bolt holding the shock fork to the strut (used a cheater bar to break it and an impact to get it out), unbolt the strut tower bolts, take strut out and replace it with your Konis, neverseize all the bolts before you reassemble.
Rear: Unbolt all 3 bolts from the LCA (the bolt furthest to the wheel snapped), remove rear strut tower bolts in the trunk (underneath the trunk carpet), remove and replace struts, BE SURE TO NEVERSEIZE ALL BOLTS
I'm sure there's a few things I'm forgetting considering its been a few months since I replaced my struts but that's the lowdown. Believe me, it's a lot better to do the project yourself to save the $300 you'd pay a shop. The total cost for parts for me to replace my struts was $40 since I replaced a bushing and a LCA bolt. That's assuming that you have the proper tools. I would reccomend a powerful impact, and a really good metric set.
