First install of springs. Does this look right?

Installed some lowering springs today. Only had time to do the front Passenger. I followed the DIYs on here as well as Bimmerdiy.com. I know the perch is a little off but it was straight until i went for a test drive around the block. Is it ok for it to be off? Also does my spring look straight? I really hope I don't have to take it all apart and start all over. That would suck

*Also the small opening goes on the bottom right? Just making sure cause the lettering for my Megan Springs are upside down. I'm just double checking. WOuldn't want anything to go horribly wrong

IMO, structurally I don't think you have an issue but perhaps the spring is upside down and thats why it didn't seat right? Also, the ride height might be off if the driver's side is seated properly. BTW, I had this same issue with the spring twisting out of the perch...I removed and seated the spring properly. Just have a shop do the spring install onto the strut. (I paid $20 for the side I had them do)

I don't think the spring is upside down because the other side doesn't sit on the shock at all. Damn I really don't want to take it all apart again. Anybody else have any insight?

If the lettering is upside down then obviously the spring is upside down.

Not true. I installed Vogtland springs a few days ago, and the lettering was upside down on the coils.

Yea I've also heard some people say there tein have been upside down as well. So basically it's the side that sits well on the shock? Cause the other side doesn't sit on the shock well at all. I'm 95% sure I installed the right way but just curious if I will have problems with the perch being a little off.

Was the spring in the perch and then twisted when you reinstalled the top hat? I don't know if it is possible, but you might be able to re-compress the spring while it is still on the car. Its worth a try and if you can relieve the tension you might be able to twist the spring into the perch.

No It was seated properly until I took it for a drive around the block

Kinda weird that it twisted with tension on the assembly. This is probably a silly question, but did you torque it down to proper spec.

I would install the other side and not worry about it. The worst thing you'll have to face is a difference in ride height, but to be candid, my ride height varies between both sides and my springs sit in the perch anyway.

Wheels bounce up and down 1600 times in a mile of driving. As the shocks lose pressure with age/ mileage the movement of the springs gets more exaggerated. After 50,000 the shocks are ending their life and you start to see this shifting over the spring perch.

SO I finish installing the fronts. Weird thing though. When I try to torque the 21mm bolt on the very top of the shock/hat the spring turns with the bolt and it won't torque. Is that normal?

Did you use an allen wrench in conjunction with your socket to tighten down the nut?

I just tightened them as much as I could when the shock and spring combo were off my car. Then when I installed everything back I tried to tried to tighten it to the correct torque and all it did was move my spring as I turned it. Should I be worried?
Note: I tried tightening it when everything was completely done and my car was sitting normally not jacked up.

I finished installing my rears today and will upload pics tomorrow. Really nice drop with Megan Springs

Edit: Is it Ok for me to have Koni shocks in the rear and Oem in the front?

Unless someone else chimes in, the way I understood how to tighten the nut on the top of the strut assembly was to use a spark plug socket, thread the allen wrench through the opening and then tighten down the nut while holding the allen wrench in place so the assembly would not rotate...IDK, but that's the process I used.
