I purchase this kit but they send me wrong kit.My car is double sided belt and they send me 2 belt evry one with one side ribs.

Someone know what is part number to double sided belt but for their kits not OEM.

Pls if someone have this info to tell me to fix this......

I have never seen a double-sided rib belt on the s65. The belts in the picture are the same as I got with my underdrive kit (made by Burkhart Engineering)

Those are the exact same belts I got with my Macht Schnell pulleys. My car is 2010 M3 DCT.

Hi,

I make some searches and find that steering pump pulley is not ribed anymore from Macht Snell.
In this way i think that is work on my car.
My car is 10/2009 DCT
Thanks !!!

So this is the right kit for you car, I’ve scratched my head on this too the other day but upon research they use a non ribbed belt for the power steering side. I took mine off and I’m going back to stock. They probably didn’t do the ribbed version cause there probably wasn’t an off the shelf belt that would be an easy solution. The belt they use can be bought easily in the case you need a replacement. Just make sure it’s routed under the power steering pulley and not over.

Enjoy this mod. I don't know what else you did to your car, but that was the final piece of the cake to my bolt ons for power. Understated mod that added a layer of rawness to my e92 m3.
