Tension struts is about $128 @ X 1 hour labor. The rear subframe bushings at $40@ X 4 5-6 hours.

What would it do to the car's handling if I just change the front tension struts and leave out the rear sub frame bushing? Labor is too costly and time consuming.

So, you guys that have ordered these parts from the dealer, what is the total?

Basically, what is the net savings over the Dinan kit?

I have not taken apart the controls arms of an E9x yet, but every other BMW I have swapped this part on did not need an alignment.

there are several other beefier arms from the m3 that can be swapped over as well.... i had a 335 and and m3 in the air and compared all the suspension components a few months ago when the m3 first came out... then i looked up the prices and said nevermind!! hahaha

At least somebody answered the question.
Now, do we have a consensus?

What are they? Please post since you have the parts # and price, it might help other members in the forum.

You are replacing a suspension link that does not affect toe. Castor is not adjustable anyway, but should have minimum affect on its settings.

Thank you very much for explaining.
It might sound like a dumb question to you, but I'm not too knowledgeable with what throws off the alignment and what needs to be adjusted to align a car.

If you are tracking the car, I would just have the alignment checked anyway.

Harold, for the rear links, this one for sure- 33322283549 - it is good idea if you have Quaife and will reduce toe out under acceleration. That is were you should stop unless you load test the other two forward links for stiffness.

Spill the beens on what you checked out on the rear.

Yah, I guess it's better safe than sorry.
Or course, I had it done after I installed the suspension, but I wasn't sure about this.
I did look, and I was reading that in most cases, Castor is almost always not adjustable.
If the castor is off then that usually means that something is worn.
I'll see how the installation goes.

I would save a lot of installation cost if I change them together with the shock and F/R sway bar. They are about 128 @ X 2.

Front control arms:

LEFT TENSION STRUT WITH RUBBER MOUNTING 31102283575
RIGHT TENSION STRUT WITH RUBBER MOUNTING 31102283576


Rear sub-frame:

RUBBER MOUNTING FRONT 33312283382 - Qty 2
RUBBER MOUNTING REAR 33312283383 - Qty 2


FWI, the front suspension on e92 is identical with e92 M3, as well as, 90% of the rear suspension. You can literally bolt on an M3 suspension and brakes ect. The only real difference between between cars is the rear track width which is minor and a LSD. This should be of no real surprise.

I measure up the M3 strut bar today and it should fit so I order the parts ( http://www.realoem.com/bmw/showparts...61&hg=51&fg=75 ). This design is superior to any straight cross over bar from a mechanical stiffness point of view and much lighter. You need ever part of the RealOEM listed page and for item #6 you need the 12 mm bolt.

Orb
This is a great thread, Orb.

Please confirm: did you or did you not buy a set of 31102283579? Were they included with 31102283575 and 31102283576?

Part numbers from http://www.realoem.com/bmw/showparts...01&hg=31&fg=05

Thanks,
Rob

Is this a trick question?
They are included.
Look at the same page that you posted and you will see that number 14 says "with rubber mounting"

If not, I have a question for you...
Who's barried in Grant's Tomb?

I saw this, but thought that I'd like to confirm with someone who has one in his hands. Sorry to trouble you with this.
