Brakes and bulbs


Recommended Posts

Regarding my03 (non - S):

1) replacing the rotors to Zimmerman drilled and sloted, good idea, problems? (also what is the minimum rotor thicknes for the front and rear's on a my03)

2) bulbs, sheesh the dealer wants $11.56 Cdn. for the turn signal bulb (PY21W)? Are they always that expensive? I see them on eBay for that much a pair... any caveats on these?

Thanks, Al

For #1, the minimum thickness is stamped on the rotor hat. You probably have to remove the wheel the read it. It will be embossed in the hat and might be quite hard to find. I have had issues with Zimmerman rotors warping on my '01S and resorted to buying Porsche OEM ones. However, the last set of OEM rotors I bought did not have the coated hat and they developed severe cracking between the holes. If you go with drilled and slotted, expect to replace them and your pads (the holes and slots act like a cheese-grater unless champfered properly.

#2, I just take the bulb to my local auto parts store and get the generic equivalent.

Good Luck,

Graeme

thanks Graeme, the place that sells the rotor said that they only increase the wear by 10%, BTW I thought that Zimmerman made the Porsche OEM rotors?

I tried the auto parts stores for the bulb, no one had it. I saw a post on another forum that Mercedes sells the same bulb for $1.83! I plan to call in there tomorrow.

Otherwise I have found a source for the bulb with a silver coating (still lights up orange) so the white light din't reflect the amber of the bulb...

I'm pretty sure canadian tire sell thats bulb in a green package. just buy some silver paint and lightly paint the head of the bulb it will look silver and still show orange, no problems there.

CT was the first place I checked, not even behind the counter...

Leaning towards the silver bulbs, appearently they are actually chrome plated.
