Hello all! new to m3

Hi all! I'm a new owner from Spain,
Just in love with the car and discovering it every day.

The car its a 2010 model in a very clean condition with 80.000kms
6 speed manual, has cloth seats, no navigation, no EDC, carbon roof, its a very striped version which i love <3

Just want to ask a couple of things:

I'm taking the car to a M3 specialist shop here to do the rod bearings, bolts,etc.. And they told me, that also it will be good to replace the oil pump, a front silent-block and also to put metallic break lines at the front wheels.

That because all these things are really easy to change at this moment, so its worth it to do it now.

What do you think of these, its really important to do it???

Also I have attached a couple of pics of the car, hope it works

big saludos

Congratulations. If you are going to put braided stainless steel brake lines on the front, you should do the rear as well. They do make a difference.

Congrats on the car and welcome!

Definitely do the bearings/bolts, but if you decide to do the brake lines do both front and back at the same time. Maybe get your windows tinted at some point as well?

Hi and welcome to the forum! And to the wonderful world of M3s!

I'm also from Spain but live in the States. Feel free to PM me if you want to discuss further.
I have two M3s, an E90 and an E92 and both are 'strippers'. That is the best way to buy an M3!!

The technical level of the average mechanic in Spain is not high. It isn't in the US either, but in Spain it's even lower. A friend has built a track Z4MC over there and the amount of stupid ideas his mechanics have is scary.

Brake lines: no need to change these unless you are going to the race track. The OEM lines are extremely high quality, probably better than whatever off-market crap they want to sell to you.

Oil pump: M3s since the E46 have had extremely solid oil pumps. No need to change or touch it whatsoever. If a mechanic offers to change my M3's oil pump I would immediately doubt their intelligence.

I suppose the 'silent bloks' they're talking about are engine mounts. Indeed, M3s eat through engine mounts and you'll need to replace them, besides, they're right by the rod bearings anyway so you might as well change them.

For the rod bearings and bolts, I strongly, strongly suggest you buy a set of BE Bearings and BE bolts. Do not replace for oem bearings or for any other set of bearings.

If you purchase from a reputable place, like Turner Motorsports or Bavarian Motorworks, you will get high quality braided stainless steel brake lines. I have replaced stock brake lines with stainless steel and the change in feel is noticeable even on the street. This is what Turner has to say:

Stainless brake lines are a must for any track driven BMW and make a great upgrade on street cars as well. Brake lines should be replaced every few years anyway and braided stainless lines offer an additional layer of protection. Rubber brake lines deteriorate from the outside and inside. The external rubber can become stiff, crack, or get damaged by debris. The stainless braiding and Teflon inner coating help protect the outside of the line from debris. And with a stronger material the line will not expand or swell under extreme braking conditions. Stainless brake lines provide a firmer positive pedal feel under hard braking by greatly reducing the expansion that can be found in stock rubber lines. The internal of old stock rubber lines can become constricted over time even if the exterior looks normal. With a blockage or restriction you can have serious braking issues that often go mis-diagnosed as warped rotors, stuck calipers, or bad ball joints. Make sure you don't overlook your brake lines! All brake lines, rubber or stainless, should be replaced every few years and any time you replace a brake caliper.

Yes, I know that they are in the business of selling car parts and it is to their advantage to convince you to buy, but in this instance their comments are spot on.

I get where you're coming from, but note that OP is in Spain. There is no reputable source because there is no reputable vendor as there is no market

Europe has the most stringent rules about cars you can imagine.

Spacers? illegal
Aftermarket brakes? illegal
Height adjustable suspension? illegal
Aftermarket suspension without height adjustments? illegal unless installed by a qualified shop
Metallic brake lines? illegal
Different wheel offsets? illegal is they widen the track more than an inch
Different sized tires/wheels? illegal if the external diameter is more than 2% different than stock


For the record, I strongly disagree with brake lines making a difference that can be noticed on the street. OEM M3 brake lines are extremely tough.

OK thanks for the feedback, I will talk with them!

The workshop it a well know here for track M3s, maybe thats why they proposed to go with the changes

http://www.rieraracing.com/

I actualy love metalic brake lines, got them in all my racebikes, but never had a car whith them, but never had a car like this one

Talk with them. The shop that set up the Z4MC in Barcelona also has a good reputation for M cars, but it is staffed by idiots.

Here's a list of what I recall arguing about with them:
Anything more than 2 degrees of camber was crazy
Square wheel/tire setups were crazy
That helper springs made the ride softer
That when corner balancing the important thing is achieving front to rear equal weight distribution instead of equaling corner balance and setting ride height for the appropriate rake desired
That it was impossible that a 4 piston brake system could work with the oem brake booster because it had 'more volume'. They only shut up once I bothered to do the calculations that proved them wrong


There is no reason whatsoever to touch the oil pump of the E9X M3. It doesn't matter if you race.

Good luck!

OP, congratulations on the new car.

I do not agree on doing any work on the car.

Drive it for a few months to get a feel for it. Rod bearings are the theme of this forum but not urgent in my opinion.

It is valuable that you learn to drive the car and avoid driving it off the road if you do not have experience with an M car or other high performance car like it. The M3 is a little rocket.

Enjoy the car and save your money for the possibility of a real repair if you find existing issues with the car. The bearings are a latent issue but no urgent.

I have driven my M3 for 4 years, it has about 121k km, and I am the fifth owner. These cars are indestructible in my experience. And I have not done and do not plan on doing the bearings for at least another three years. I will wait until it hits 160k km.

Buena suerte, hermano!

Thxs for the answers and good thought guys!!!
Im into rallies with bikes and some times I tend to over do things hahaha...

The workshop explained me the oilpump thing, they been following the oil pressures and discovered that around 100k the pressure starts to fade and goes form 5 from new, to 3.5 or so, the pumps don break they agree, but recommend to change it if pressure is not stock.

The break lines ara a complete set, they recommend it for track use, and because I told I will use as recreational and some track days, they proposed it.

Next week I will be taking decisions. So by now this weekend I'm going for a trip over the Pyrenees mountains, to get to now a each other a bit better and enjoy a little bit !

Yes, that is their typical state. Good thing you're getting them changed!


Enjoy the car!
