I get my suspension installed next week and I have a gut feeling I'm forgetting parts. Going from stock suspension to a X74. I'm reading conflicting things about it being complete it not being complete. Here's a breakdown of what I have:

Front and rear X74 springs
2x Rear B8 Shocks 24-029940
2x Front B8 Struts 22-046140
2x Rear sport bump stop 99633310503
2x Rear Shock boot 99333310701
2x Front Strut boot 99634350500
2x Strut mount rear 99633305903
Front strut mount kit (strut mounts, bearings, hex nuts) KIT-3545001KT at FCP

Before somebody mentions "where are the bumpstops for the front?" Confirmed with Bilstein USA via a person over the phone that the front struts with this part number have built-in bump stops (because not all B8s have built-in bump stops).

For the front, can parts 5, 6, 8, 9 be reused or are those considered wearable items and should be replaced?

Same goes for the rear, can5, 6, 7, 8 be reused or are those considered wearable items and should be replaced?

I just want to get everything ordered since the car is going in on a Friday, I don't want to be without a car on the weekend waiting for parts.

Thanks in advance!

On the front I replaced #6 also since they are rubber. #’s 5, 8, and 9 are metal and I reused. I haven’t did the rear yet.

Nate.Evans

is #6 two parts? There’s a 6.5mm one and a 3mm one.

good to know about 5, 8, and 9.

CapeCoral944

No, it is 2 different sizes.

Nate.Evans

So I assume if I want to go lower use the 3mm one? Seems to be just compensating spacers after reading a bunch…Are they even necessary and can I leave them out altogether?

De Jeeper

They should be specific to a suspension package. The dealer system usually has an option code attached so they can verify its a correct match to the vin.


Autoatlanta only shows the 3mm one for our cars if that means anything.

Nate.Evans

So it should be the same case for the rear as well, being able to leave them out to lower it more?

CapeCoral944

I wouldn’t leave it out, it was engineered to be there for a reason. Maybe for noise or to cushion the strut bearing.
