Pulley grenaded. Which pulley kit is best?
2011 C63 with 59k.
Which pulley kit is best?
Weistek?
Sharduls?
FCP EURO
Weistek and Sharduls are billet.
What is FCP EURO? Is it just OEM parts or better than OEM?
I know it's not billet but it's half the price.
Sharduls seems good but i have seen people having issues with one of the pulleys rubbing on the tensioner with no solution other than shim it out.
Are there any others?
Plan on ordering a set tomorrow just don't know which one.
Any help you all can offer is greatly appreciated.

Pretty sure fcp is oem. The great thing is though if it breaks again it’s lifetime warranty forever. That’s the route I’d go and oem fitment.

If they are the exact same garbage parts i won't use them.
I was thinking maybe they were better than oem but just not billet.

They are not garbage they wear out like any part. You got 50k miles out of them so you get another 50k out of new ones. I’d use them cause there is zero benefit to the other ones other then potentially longer lasting however with a lifetime warranty I have life time too for less money.

go with the bullet pieces if you drive your car hard. my new oem pieces blew in 1 year and maybe 10k miles. took out my thermostat housing along with spraying coolant everywhere.
all it took was one full throttle press, double downshift jerked the engine hard enough to cause the plastic pulley to fail.

But i don't really need billet either. Just figured the Fcp was somewhere in the middle.
Are the three i listed the only ones on the market as a kit?

There are only two upgrade kits, Weistec and UPD. The FCP “kit” is 100% OEM stock.
There was recently a video on YouTube that showed the Weistec pulleys having super cheap bearings. Not sure if Shardul’s are better or not, but that would be the deciding factor for me. If they’re the same, flip a coin and replace the bearings with good ones and they’ll last forever.

I am a mechanic by trade and we never use cheap Chinese bearings.
Thanks for the info

I got the UDP kit and didnt experience any rubbing, In fact, noise level are just like OEM. I did have to change out a bolt style (search thread for the part #). As for bearings, they used a pretty decent type (Nachi bearings).

Ran my last C63 with the full 5 pulley UPD kit for a year. Also had a 5 pulley set on my old E55 for about 5 years. Can't think of a better upgrade for a maximum reliability/durability/longevity build. Whether your OEMs grenaded, or you are putting them in as preventative measure.
Shardul makes a quality product and many, many users have posted here and on the E55 forum attesting to superior craftsmanship of Shardul's products, especially when it comes to his pulley replacement kits!
