cant seem to find any full installation youtube videos for the 8th gen nor 9th gen, i only found reviews. As for the HFP suspension, i can only find the manuals for the civics, not accords. If you could link me, id appreciate it. Im having a bad day searching..I believe its just a direct swap. unbolt the stock struts/shocks then replace with coilovers, bolt back on. Check out 8th gen accord coilovers installation( if any on youtube) it is pretty much the same process.
Also, there's a installation manual for HFP suspension on college hills honda, follow that and you're good to go. good luck
