there is no 1IS stuff on his website as of right now, assuming he hasnt updated it yet. i dont think he is doing a rear kit. no real reason. the rears are already 2 pot.Interesting!
350phi you listed rear brake setup as well for the MK1 IS300 in your website, would the emergency brake still work/fit? is there a need to enhance/enlarge the brake cylinder?
the e-brake is all on the rear of this car. nothing to do with the front.
the master cylinder has been covered in this thread for IS350 calipers (i believe more than once). stock one is fine.
