Wassup bro's?... Im am about to purchase some coils for my whip. Im just a little confused on what other replacement parts I may need to get the job done right. I've been looking on real oem to try to get a handle on it but its a little confusing with all the little parts and not actually having the coils to see exactly what the assembly looks like, I know its not as easy as buying the coils and thats all. I have dynamic drive/active steering is this something I can do or should i have my indy install it? (I've done the Alternator bracket gasket as well as some other fixes on my car) never suspension related stuff tho. All help is appreciated fellas, Thanks....

Subscribed...Been wondering about this myself. People posting coils they installed but never mentioned if they needed to get some extra bits to complete the job. Sorry, I don't have much to contribute.

BTW, which coils are you considering? Maybe that would help along with people posting.

BTW, here's a thread on installing KW Street Comforts on an 05' 545.

Leaning towards ST coils, made by KW and from what I've read are the some as the KW street comfort without the lifetime warranty. So I figure it's worth a shot.


I actually subscribed to this thread quite some time ago, doesn't show much of what was needed tho. As far as replacement parts, my car has 91k on the clock with OG sport suspension so I know some stuff needs to be replaced. Already replaced control arms and tensioners. But I'm talking about items related to the install. No one ever says what else they replaced, search button is my friend but I haven't found much

I thought ST coils are the same as KW V1, not the Street Comfort.

That KW install thread mentions keeping the existing top hat but I don't see anything else.

Yea your right identical to V1's my mistake... But yea I probably would change the top hats just because, at 91k how much longer would they have to go. Also when I take a look at real oem at the construction of front and rear assembly there's some pieces that I'm not sure need to be replaced or that don't matter because there coils. Essentially a coil does the same job as a stock spring and strut ( don't shoot me I know there's some differences) for the people that read this and try to go off, lol.. But yea I'm sure there some things I could change out so I won't have to go back in there or better yet that MUST to be changed.

Just replace your top hats and everything else will be in the box with the CO's. .

Agreed with above statement. When I had mine installed, I forgot to replace my upper shock mount with new one. With stiffer shock (compared to OEM), it had failed within 6,000 miles.

Ok cool, top hats are both front and rear correct?

You will NEED TWO of these:

Some people change out the top mount nuts, but we reuse them.
