2019 RWD 440i

So I’m finally getting time to get these ST XA coilovers installed but wanted to get some advice on reusable hardware. I know the top hat bolts are torque to yield so they’ll need to be replaced for sure (5 front, 3 back each side)

The top hat kits i found on fcp do include the top hat bolts, but not the bolts connecting at the bottom of the struts.

Does anyone know if the front/rear control arm bolts and front strut knuckle pinch bolts are also TTY and need to be replaced? Or can I just reuse those?

Also - my car has only 45K miles and 5 years old - I’m still debating whether its worth it to replace the whole top hat or just the TTY bolts - any experience on this is welcome (but obviously I’m trying to be cheap &#128514

Can you share the link to FCP Euro kit?

At 45K miles - if one were to approach this project in a more defensive manner ...

- Inspect all suspension parts with rubber bushings
- Replace these parts and ...
- Install coilovers at the same time
- Perform 4 wheel alignment (which will be at risk later if the parts with rubber bushings are at the end of their useful life)

I had ST XA coilovers on my 2013 335i before it got totalled, you’re gonna love them, their awesome. Im probly going to get them for my 340i, how much are they going for now?

Here it is, even comes with dust boots. However, these are the 3 bolt top mounts for the front suspension- later models like mine are 5 bolt

Im thinking ill replace everything except the top mounts themselves, i should be able to buy all the rubber bits and nuts and bolts for less than 80 bucks. Of course i may regret that if i find the built-in gaskets on the aluminum top mounts are bad but I’ll take my chances and report back.

I think i stumbled on a crazy deal when I got these. First i checked on the ST website to find the right part number, 1822000G, which they sell for 1370 direct from ST (they also let you choose a spring color if you go this way). Most retailers are selling for 1450+

I found them on mlperformanceusa for 1025 - 1150 all in including shipping. I think the price is still the same on their website.
