Bilstein B12 Prokit

Hey all

I have a b12 prokit awaiting figment. I'm going to do this myself but I am unsure how much a straight swap will through out the alignment/geometry..if at all?

Does anyone have any input/experience.

I am getting the geo setup but really need to know if it will be drivable after fitting.

Answers on a postcard please

Cheers
Dan

You will be absolutely fine. I went from an SE to a B12 kit with no dramas

I have ordered TRW front control arms.

Will I need to readjust the headlights?

if your changing the arms, you want to be getting it booked in for alignment straight away, as the alignment will be properly away to fcuk!

also, if you have Xenon's you don't need to do anything to the lights as long as you reattach the level sensor to the arms.

It will be booked in, shouldn't be too far off as the arms are of the same. I'm not going M3 arms.

All fitted. Took longer than expected but it's all on including new front control arms.
Booking her in for a full geo setup this week hopefully.

Took her out for a quick spin, couldn't resist, first impressions are; firm but smooth and quiet.

The standard stuff that came off was...well after 100k..completely knackered. The rear dampers didn't even extend once pushed in.

For those that are looking to fit this kit make sure you observe the "instructions" as there are OE bits you have to keep and reuse.
The strange thing is the lack of bump stop on the front shocks, the Bilsteins are about 3x as thick mind.

Will get some pics tomorrow.

Hi, I have recently in stalled the B12 Pro kit along with front M3 upgraded arms. I am curious as to how your car rides now? I am about 80% happy with the setup after a month on the road. It is fabulous on freeway's and at high speeds. The car is tight in corners and it feels firm. My complaint is the rough ride at times on city streets that are uneven. The front end can be jarring while the back end is a little bouncy. I am hoping that once I switch over to my summer tires(which are Michelin PSS's) the ride will be a little more compliant given the absence of my winter run flats.

Look forward to your feedback.

Cheers,

D
