The hardware that comes with the fronts should be fine, IIRC. On the rear lowers, you need to get your own. I don't remember the sizes or other specifics, but if you do a search, Autocrosser posted this information several months back. The top bolts in the rear are a bitch to do. It helps to have a second person. I drilled the hole in the sheetmetal out just a tiny bit so I could use the hardware that came with the HALs for the top rear bolts. No big deal. I believe others have posted about using a flexible extension to get at those bolts (again, a search should turn up this info). I used my son instead. He's skinnier than me, and pretty flexible. Good luck. You'll love those shocks.
