    So I bought four 12 oz bottles of BMW OEM brake fluid (part no. 81220142156) from the dealership for about $20 which is supposedly a low-viscosity brake fluid that our ABS and traction control systems need. I removed some of the Pentosin DOT4LV brake fluid I had in the reservoir from my failed attempt at flushing my system on Saturday. I filled up my pressure bleeder with all four bottles under the assumption I would make three to four passes around the car at each bleeder point. I ended up doing four cycles, in the following order: back passenger caliper, back driver caliper, clutch, front passenger caliper, front driver caliper. I didn't have any of the issues I had from Saturday so I think I successfully flushed and bled the system. Overall I liked the pressure bleeder system, it seemed to work well if you have excess brake fluid in there. I cleaned everything up, got it off the jack stands, took it for a spin, and everything seems to be in order.

    Some notes:
    • The BMW brake fluid is an almost lemon gatorade color compared to the amber Pentosin so it wasn't too difficult to discern when the lines were flushed to the new fluid.
    • The clutch now feels lighter but also more sensitive. It's not night and day, but an improvement in my mind. Not sure how much is up to the SS brake line, the modified CDV, or low viscosity brake fluid.
    • Overall the job would be much easier now if I had the experience, but even without any experience it wasn't too bad.
    • Removing the wheels was a serious struggle. The wheel and the hub had basically rusted together on all four corners. I had to put my whole weight into pulling each one off. I put anti-seize compound on the hub and the wheel where they made contact so hopefully they'll be easier to get off next time around.
    • While the wheels were off I weighed them. The rears, with Toyo Proxes T1 Sport tires (manufacturer claimed 26 lbs), weighed an average 53.4 lbs, so the rear wheels weigh about 27.4 lbs. The fronts, with Toyo Proxes T1R tires (manufacturer claimed 26 lbs), weighed an average 49.8 lbs, so the front wheels weigh about 25.8 lbs. That's why a set of Apex Arc-8s are on my list of mods, try and shed about 7-8 lbs per corner.

    I remember reading somewhere that someone thought that the OEM brake lines had stainless steel weaving in them so there was no point to upgrading to SS lines. I decided to cut open one of my old ones. Looks like rubber and cloth/cord (like a tire) to me:

    Yeah it wasn't bad. I would use the two guides I used for the lines and just be ready to spend an afternoon doing the swap and bleeding the system.

    My Koni Sport (Yellows) Shocks arrived in the mail today along with the Rogue Engineering rear shock mounts (RSMs). All the part numbers on the shocks and struts matched, although the left strut has a slightly rougher paint finish than the other strut and the rear shocks. Not sure what that's about but should not matter hopefully. Tracking for the other parts I ordered suggests they'll be here by the end of next week!

    Most of my goodies have arrived so that means I can start doing more maintenance/mods on my car starting next week. The things I want to try and tackle myself are:

    • Suspension refresh: Koni shocks/struts, Z4M FCABs, OEM ancillary parts (dust boots, bump stops, spring pads, etc)
    • Swap out the stock intake box for the BMW Performance intake I got from illirep (for personal future reference, BMW part nos. 13720429613 [intake] and 13720431649 [filter]).
    • Swap stock shifter for UUC Evo3 short shift kit, although I haven't looked at how difficult this can be.
    • Swap old rotors for BMW Performance drilled rotors from Tippey764. Still need to pick out pads. Any suggestions? I'm thinking Hawk HPS but don't know a whole lot about brake pads.
    • Paint the calipers yellow with my G2 kit (although I may go to red or phoenix yellow). I still like the way this looks in yellow: http://www.zhpmafia.com/forums/showt...582#post433582
    • Full exterior detail, although I may leave this one to a specialist just to start from a solid base and do future detailing myself.

    Things I'll probably leave to a mechanic:

    • Shark Injector tune
    • Power steering fluid (I have the fluid just rather not do it myself).
    • Alignment
    • Diagnose issue with my windshield washer pump.
