Subject: Responses on brakes/rotors/shocks for 89 325i (long)
Item Subject: cc:Mail Text
List members -
I received a number of recommendations on shocks and brakes/rotors for
a 1989 325i. Below are the shortened responses. Thanks to all who
responded! I'll go with the stock rotors, Metalmaster pads, and
(haven't decided) Bilstein HD or Koni shocks.
The reply is long but if you're in the market for the advice it's a
Be sure to check out the E30 page for more info:
I would recommend Repco/Axxis Deluxe pads The factory rotors (12 month
warrenty!) The Ultimate Garage see my parts page
can supply all of these parts (I think), but the bolts for sure.
For shocks I've been using Boge Turbo Gas, because you can get all 4
for $200. I'm thinking about getting Bilstein's next time though for
I just put Koni's on my 88 325iX. Heaven.... Firm yet comfortable.
I was a little concerned as Koni calls their shocks sport-shocks, but
they are great. If you go this way, make sure you get the hydraulic
rears. Originally Koni sent me the high pressure gas rears. They had a
severe rebound that over powered the rear springs. Koni send me the
hydraulics under warranty. The Konis have an adjustable rebound, the
compression is not adjustable.
Bilsteins; I had them on my 320i and the rebound was too severe.
Never again....If you go the Bilstein way and want comfort, IMHO; do
NOT get Sport shocks, only HD (heavy duty).
Cost ? The Koni's were $480 from RD Enterprises in San Diego ($50
cheaper than Imparts in St Louis) The Bilsteins were in the $369
range from Bavarian Auto in New Hampshire. Koni or Bilstein shocks
will last 100k miles.
If you are the type to sell the car in a year or two, or cost is a
factor, you may want to consider getting Boge Turbo Gas shocks. I have
heard good things about these shocks. These are in the $225 range from
Bavarian Auto in New Hampshire.
All prices referred to are for an iX which are more expense than a
325i. (plus installation)
I would appreciate knowing how it works out.

I have an '84 325e that sees no track time either.
Use OEM Rotors. You should be able to get a discount from the dealer
(if you are a BMW-CCA member) or through the Roundel. There was some
problem with after market rotors a few years back.
Pads: I like Repco Deluxe, (the company has been sold so it is no
longer Repco, but it is the same company that make "Metal Masters")
The pads seem to last, don't squeal, and are low dust.
Shocks and struts: I put Boge turbo gas on my car last fall. I felt
for the type of driving I do it was not worth the extra $$ for
Bilstein's. If you do go with Bilstein's get the H.D.s not the
sports. I have sports on my tii and it beats the **** out of you.
I purchase my parts from: the local dealer (at 15% discount), BMP or
Bavarian Autosports. BMP & Bavarian have webpages.
ted: i just went thru this a more myself. here's a bit of what i
determined listed loosely in order of significance. Best parts source
for hardware is steve d'geralamo - hands down. he know the spec.'s on
all the hardware that both he & his competition sell. Steve is also
where i buy most of my parts from. his website is
rotors - best factory is balo. i went w/ ATE though because i wanted
to try their new factory slotted rotor. either are good.
girling's product quality is generally on par w/ate but balo is still
pads - depends on your priorities. if brake dust annoys you, go with
repco deluxe pads for < $40 per axle. if dust doesn't matter, factory
jurid pads are probably the way to go at about the same price. if you
want to spend a little more for extra stopping power and don't care
about dust, go w/ ferodo pads available from korman
(http:\\www.kormanfastbmw.com) or aj usa (http:\\www.ajusa.com)
shocks - bilstein or koni are the top brands w/prices to match. boge
is a more reasonably priced product. all three offer shocks of two or
more "firmnesses". normal & firm are generally the designations.
koni's are also adjustable. fwiw, boge was oem for the e30 m3 so i
since you're doing this much, i suggest you check the car's control
arms & ball joints (which are integral) and the control arm bushings.
keeping the bushings in good shape helps the ball joints last longer
imho (but i can't prove it). check the brake lines too whilst you're
there and its definitely probably time to change the brake fluid.
steve can help you with any all questions about parts selection and
related maintenance items to consider.
89 325i too
I think (from my experience with my 1988 325IS) that you will not go
wrong with Bilstein Heavy duty (not sport) shocks and struts, the
Repco/Pbr delux brake pads.
The Bilsteins will give you a nice tight ride with great handling but
you will not smash thru the bumps.
The PBR brake pads might offer a little better perf than the stock
pads, but they are quiet, clean and easy on the rotors.
If you decide on some track time, try the repco/delux metal masters.
Rotors? Go with the stock oems. You can't lose with this setup.
The best price I got on the Bilsteins was from all Euro at
i like the looks of the cross drilled rotors but for non track driving
just go for the standard rotors. the for brake pads I have tried two
different types. the current ones are the padgit, i believe thats the
way it is spelled, organic. the pads work well but leave a lot and i
mean a lot of dust on the wheels. i believe i will go with the rebco
ones next time. from what i have read in the digest they do not dust
as much. the metal master will give you the most positive braking but
they have the potential for wearing the rotors.
for shocks i have only one that i would recommend to everyone and
those are the bilsteins. if you do a fair bit of agressive driving go
for the sports otherwise, the standard ones will work just fine.
first of all, i would be very surprised that your rotors are worn
after only 56K miles. you probably on need to change the pads. the
rear rotors will definately not be bad. i finally changed mine at 175K
because i felt there should be somthing wrong at that mileage. in any
case, my first rotor choice is the factory. they come with a warranty
for one year that they will not warp, no mileage limit. stay away
from ATE rotors. warp very easily and will only withstand one pad
cycle ie. can not put second set of pads when time comes because they
will definitely warp. i have had no trouble with the brembo
replacements, decent price. one rotor that would be an upgrade are
the ATE powerstop. they are slotted and are of better construction
then the regular ATE, but since you only use your car for the street,
save the 20% additional cost.
now pads are a neat story too. the factory are very good, but they
produce a lot of dust. the pad i would recommend are the pbr/repco
deluxe. very good for what you are doing and very little dust and the
color of the dust is light. BUT you have to make sure that you use
some kind of antisqueal device.... paste or strips.
adjustables are great. i love them, but i go to the track and
autocross. if you are just going to use them on the street, waste of
money. the bilstein sports may even be too stiff for your taste. try
the bilstein heavy duties. great stuff. stiffer than stock, but not
harsh. stay away from the boge. you might as well have gotten stock.
