Some thoughts on Turner Motorsports complete brake kit


I"m a newbie here but wanted to share my recent experience replacing the brake pads and rotors on my 04 325CI. I just recently bought a 2004 325CI with a low 59,000 miles and from the minute I saw it I just had to have it. The car runs excellent, however, the prior owner had installed some cheap aftermarket rotors with some red pads. I'm not sure the brand but they appeared to be a ceramic compound. The rear rotors were worn down with a lip on the outer diameter which usually tells me an improper fitting pad, there was also a lot of rust on them although the vehicle is used daily. I also had a slight steering wheel vibration when braking from 60+mph.

After much research on this site and careful deliberation I decided to go with a complete kit from Turner Motorsports. The price seemed reasonable and they claimed their rotors are the same as the OEM manufacturer.

The entire kit cost me ~$370 delivered to my house and it included 4 rotors (Zimmermann BMW coat Z) front and rear pad wear sensors (which I did not use) a set of Axxis/PBR Metal Masters pads (semi metallic compound) and a quart of ATE Super blue. Installation took me about 3.5 hrs. I was taking my time by cleaning the inside of every wheel, inspecting the underside of the car and the rotors had somewhat rusted on to the hubs and had to be coaxed with a hammer to be removed.

Once everything was put back together I went ahead and bled the entire system. I used a Mityvac MV8020 (42.99 from amazon) This one man brake bleeding kit is more than sufficient for the weekend warrior although I would not recommend if performing brake jobs for a living. if money is tight a second person pumping the brake pedal with a clear hose from the caliper to a plastic cup will do, however, I am not a fan of stroking the brake piston past it's usual point of travel. One more point to remember is to use anti seize compound on the rotor hubs, it will make removal of the rotors much easier the second time you have to do your brakes.

Once the brakes where bled I proceeded with pad and rotor Bed-in. Axxis recommends 10 stops from 40mph to 10 mph with 1/4 in between for cool down. This proved to be more than sufficient although I still do not have that initial bite that my prior BMWs had as well as my 2010 A3. I'm hoping that with another 300 to 400 miles it will improve further.

Overall, I must say I am very satisfied with the kit from Turner Motorsports (no I do not work for them and as a matter of fact is the first time I bought anything from them!) For someone who is not afraid of getting a little dirty on the weekend this is a very easy and high quality kit to install on your BMW. I do not autocross my car, however I am somewhat aggressive on brakes (late braking on turns) Next on my project list are my control arm bushings as I noticed a little too much play while installing the rotors. I thought BMW had addressed this issue by the time the 04 had come out but apparently not. I'll be buying those from

I have had the same good experience with this package. Initial bite is a little less but in the end they stop very well and there is much less dust that is not as corrosive as OEM! Not sure why the pads have such big chamfers but when the full pad area comes into play, the braking improves considerably! Give it some time for you to adjust and then enjoy! Want as good a deal with CABs ? Powerflex! or some other rotational urethane bushing.
