Need help with Bilstein part#

[Jinx]

I did a "search" and could not find the info I need.

Exactly what Bilstein part numbers do I need?
Eibach Pro Springs Font=425/530 progressive Rear=200/300 progressive. Dropped factory height about 1.5" front and rear.
I've seen some packages listed for "lowered" cars, but they don't list the actual model # of the shocks/struts. Anyone know??


Below is why I've been looking for this info. (read it if you want to)



I noticed this weekend that the car is pulling to the right and I also have to hold the steering wheel slightly to the left to keep it straight. I checked tire pressure and they are all even. Factory C/C plates are adjusted as far as they will go for proper alignment. So my guess is that , with the Eibach Pro springs and the factory shocks/struts (installed 2yrs/40k miles ago), that the shocks/struts are starting to go?? I haven't been abusing it, no speed bumps or potholes at 20 MPH or anything like that.

I'm thinking I only want to fo this once so here's my list:

4 bolt C/C plates
bumpsteer kit
X2 ball joints
Billstein shock/struts

Trying to get a solid, yet comfortable, street ride/ daily driver.

Can all this be done in my driveway in 1 day with help? Can we "eyeball" the alignment enough so I can drive it into Day's Tire for a proper alignment? Is there anything else I should be looking into, suspension wise, while it's appart? Any comments/suggestion on parts and brands are welcome.

bilsteins are the same part number for lowered or normal hieght. You are thinking of other bands. some people run the fox body struts on lowed cars. bilstein has the same part # for both.

for the hd's the part numbers are.
v36-4138-h3 up front
be5-6418-h0 out back

you can run sports or race for higher spring rates but on a steet car the HD's are proably the way to go.

for the hd's the part numbers are.
v36-8138-h3 up front
be5-6418-h0 out back

I'm thinking a typo?? V36-4138-H3 is what Bilstein has listed.
This is why I thought I'd ask about the actual numbers (conflicting information)

V36-4138-H3 up front struts is what I have. They may have changed part numbers cause about the time I bought mine, three or four years ago, they combined a couple struts that were the same but listed as regular and sporty.

BE5-6418-H0 out back shocks... (with bloomin' onion)

They have "variable valving", whatever that means but they handle your car at stock height and they are just as good at a lowered height.

Well I swapped position of the 2 front tires to make sure I wasn't having sidewall seperation issues. On the drive to work this morning, nothing has changed, it still drifts to the right. It even does it in the opposite lane (quite 2 lane highway with no traffic allowed for this opportunity).

I've got everything lined up for purchase, however, are the last 3 items on my list really necessary?

4 bolt C/C plates
Billstein shock/struts
quad shocks ?
bumpsteer kit ?
X2 ball joints ?

Thanks for the Numbers guys

I would not do the last two.


I would put it together try to get you alinment close by eyeballing it. then take it for a drive. if you don't have bump steer leave that alone.

as long as the tie rod stays at the same angle as the control arm bump steer will not be bad.

the x2 balljoint adjusts you roll center for lowring but take the tie rod out of relation with the a-arm and it makes you need the bump steer kit most likely.

on a street car I would not do this at only 1.5 drop. you roll center is not even really that affected from what I have read till over 1" drop.

Changing the quad shocks are not necessary

Well I've decided to get the alignment, but I have to wait for the shocks/struts and the C/C plates to come in first. Just ordered them this morning. As for the rest, I'll wait to see if it's necessary. Thanks for the info guys.

I agree. It seems like the latest fad on this forum is for everyone to go get a bumpsteer kit. I guess it could be that I am one of the only ones without a bumpsteer problem; more likely, I'm guessing that people are trying to fix something thats not broken.
