Hello Guys,

I am posting this here as many of us in the states have been buying new rod bearings for the S54 and S65. The reason is this is one of the two major weak points of the car. If you were not aware there was a recall done on rod bearings because they have a tendency to go bad.

Because of this as a community we worked together and made our own GB group for buying bearings. As of 4/21 we have a GB in progress so if you wish to join let me know. If not you will have to wait till we get 5 people wanting bearings. That is the minimum we need to get the discounted prices.

S54 Bearing Kit -
$226.44 -- 6 Upper / 6 Lower bearings
$10.91 --- Group rate shipping to WPC
$39.00 --- WPC cost with 20% discount
$20.30 --- Shipping from WPC to me then to you
$296.65 -- Total for GB each
$5.00 ---- Just in case shipping is incorrect
$301.65 -- Total less international shipping.

European Shipping is $50-60 depending on location. If some of you live near each other you can split shipping costs.

Rod Bolts for motors that are 2003 - newer ONLY!!! 2001-2002 do not need bolts as per BMW re-use the current ones.
$42.90 ----- x12 Rod Bolts at $3.41 each and $2 for extra shipping..

*Please remember I am not a business and are doing this as fellow enthusiasts.*

WPC treated OEM bolt pricing would be as follows - This is not a coating but a treatment.

Here is what is done

2. Wear Prevention of Sliding Parts of the Metal Products
On sliding parts of metal products, a lubricant is usually used. Under certain conditions, a lubricant dries up and friction occurs. By spraying abrasive, the surface structure becomes surface pressure resistant, creating small indents to make it difficult for lubricant to dry up, and making a near no-contact state, reducing the oil temperature and preventing the friction. When WPC treatment is applied on engine parts and other sliding parts, slide resistance is lower, increasing the power and providing higher fuel efficiency, and shortening the initial engine running-in period. It also prevents burns and scratches.

3. Diffusion at Normal Temperature Penetration Coating
There is a limitation in physical property of a metal material. By spraying metal particles, its component element is diffused over the material surface and the diffused coating, and the surface gets alloyed, to strengthen the material. The treatment is used for pre-treatment of the plating and coating to increase the adhesiveness. By spraying metal particles of low melting point and low hardness, room temperature dry plating is possible.

...and #1 (which wasn't used in our application) for reference only

1. Surface Finish Heat Treatment
Surface temperature of powder metallurgy alloy increases by fine particles peening, and metal binder in the powder metallurgy alloy will get soft, and each grain will combine solidly. Structure around the surface will be changed to be smooth and high hardness and adhesion of grains will be enhanced. Therefore, it is possible to increase wear resistance and durability of powder metallurgy alloy. Using this technique for cutting tool made of powder metallurgy alloy, we can obtain the cutting tool having the good wear resistance, durability, and increasing mechanical characteristic such as resistance to chipping.

I'm thinking of ordering a set of s54 bearings off m3dragom.

I have been in contact and he said the price is 312 dollar's plus 40-50 shipment.

Anyone interested in jumping on the band wagon?

At £300 they are not far off twice the price of a standard set. I have not yet heard of anybody who has changed a standard set having any further issues. If you change them once every 60k miles that would be the life of the car for most people. I will need a set at some point but will most likely just go for OEM or King.

Good to know. I have heard good things about king racing.
I didn't realise these are twice the price of OEM. I need to price original bearings at my local and see.

Lead time is 3 weeks to you as heads up.

I think my pricing might be slightly out of date, King are £180, I suspect OEM slightly more.

Total for oe brings shipped to you guys is 332 us. That includes shipping from dealer to wpc to me then to u.

These are wpc treated hence the cot differemce. Not just a replacement bearing
