135i caliper pistons from centric - anyone use these?
I found these on ebay. Since BMW doesn't sell them and the only other options are quite pricey. I wonder if anyone who doesn't track their car has given these a go.

Here is a picture of my pistons and dust boots. The ceramic tip and the dust boots look perfect. How big of an issue are the pistons if someone doesn't track their car? They look perfect to me.

Just to add a general comment on the centric pistons - I'd wager if you're not tracking your vehicle, the centric stuff should be good enough for a daily IMO. The stock pistons are no problem on a street vehicle, and show issues only on regularly tracked cars with many track level heat cycles/exposure. For that the racing brake or turner piston upgrades are an option.
EDIT - Sorry, forgot to say Centric is one of the brands I'd trust, if they were no-names then that's a different story. |

Under track conditions or even for a daily? I was going based strictly on company size/recognition of course. Most people replacing pistons are going for an upgrade so I suspect the sample size of people looking at using standard replacements is quite small...

I bought these calipers used and I feel strongly that a non tracked car probably will not show many issues but I like the idea of replacing them with a solid metal substitute if its viable. I wouldn't have any plans to track the car either but its more for peace of mind. |

verdict is in. Aluminum pistons. Honestly, this is the most inexpensive route to get solid metal pistons for caliper rebuilds on the 135i.

I don't understand why you want to replace the stock pistons. The phenolic tops are actually a design feature to reduce heatsoak in the caliper. They can stand some degree of track use. You have to do some serious track use to damage the stock pistons. it seems to me its only people using specialist track brake pads, and semi-slick tires that complain about the durability of the stock piston. The first failure point of the stock brakes is likely to be the dust seals, which will degrade at high temperatures. The OE dust seals available as a spare part from BMW.
