Some of it is based on what Sharkwerks recommends but most of it is based on what is needed for being able to fine tune the suspension a bit more for track use. Besides the springs, the rest of this is overkill for just street use. If just for street, I would only recommend the springs and a DSC suspension module.

No problem when the front lip of my GT3 style bumper is broken off, but when i put a new one on there is almost NO WAY to avoid scraping..When i lived in AZ i was able to navigate dirveways & keep my lips pretty safe, seems IMPOSSIBLE here in CA..driveways are way to steep and dips and it drives me nuts...however the car looks SO MUCH BETTER with a lip and lowered.

 

I'm in the same boat as OP but my debate is more if I should and not worried about premature wear based on the feedback on this forum and Rennlist. It's a common debate on modified cars, wearing out the shocks prematurely. The Eibach Pro Kits should not prematurely wear out the stock shocks(with or without PASM) and many say the ride is improved.

The common thing to do with this are wheel spacers as well.

 

bilstein damptronics, love them and my brother has the same. If I didn t have pasm I would of done h&r coilvers. Always been best performing and comfy and I've owned all brands kw v1,v2,koni,h&r

I'm never been a fan of swapping aftermarket springs on stock shocks. For looks purposes it can work but performance is usualy short lived as the shocks wear out much quicker while having less travel then originaly designed for.

 

how would you say the ride compares to oem ? love your car/wheels/stance

 

It sways alot less, body roll... Difference between regular and sport mode is very noticeable and I use both frequently. If my memory is correct regular mode now is like sport mode was before but a bit less. The coilovers are spun way down though which can affect overall stiffness/harshness. It inspires great confidence with the bilsteins damptronic. I am currently running 19" on mpss, the ride on 20" with pirelli pnero was more comfy but also more bouncy and less planted on hard runs.

 

How do I tell if my car has PASM?

 

You have an S so you do and this "shock" button" turns it on. Details here.

The linked article is most helpful.

 

How is this even a question? Do it!

 

Nice car Bimmerfreak...What lip is that?

 

This is mine lowered after debating for 3 weeks.

 

Wow...looks great with those wheels. H&R springs? Is that atlas gray color, or metallic blue? Can't tell in the shade but it looks really nice!

 

Eibachs Pro-Kit after a month of settling.

 

Thank you. It is Midnight Blue.
I am lowered in ZMS / JIC Magic Coilover.
