Drop Hats.....

[RobertB]

I have a pair of E90 hats here and noticed the hole for the shock is larger than the E30 ones. There's also some sort of countersunk bushing there. Do you install as is or do you remove that "bushing"?

Do you have this on your M3? I'm thinking of getting a spring hat... until I saw this E90 spring hat thread. :)

Now that I've peeled the label from over the hole I can see that..lol..(putting away my grinder)

They are not completely concentric with the strut shaft so the oblong portion of the "drop hat" rubs on the inside of the strut tower. I had to grind mine down so that they were round/concentric in order for it to not rub. Also had to POR15/repaint the inside of the strut tower from where it scraped. Take care of this before the steering binds up on a corner like mine did. Not fun.

Do you have a photo showing where to grind?

Thanks

the spacer on the e90 hats are not welded on they are splined and pressed on

So can anyone give me the part number for these? Im trying to order some.
I was given this part number 31-33-6-764-093. When I type it in on Tischers site it says its for a 128i? Is that the same part as the e90 3 series?

I asked for an e90 drop hat today and I'm holding that PN in my hand after buying it at the dealer for $10.91. After comparing it to the e30 version they sure look totally identical except for the height, the drain holes are in different positions & there is a spacer welded to the bottom of the e90 version that I'm sure I will have to deal with somehow.

The e90 one is thicker and being non magnetic also seems to be aluminum.

I think I may have found it. Is it part #15 in this diagram

Wtf im running these drop hats with bilstein sports and H&R races and they make grinding noises when turning. What the hell?

Yes JOMs should work with drop hats. The top of the spring is the same diameter as a stock spring, and it seats in the stock spring hat and strut mount.

I dont think he noticed that they were JOMs.

But don't JOM's work with drop hats? It's what it said in the Group Buy post

[CabbE30]

Why is that?

Its not just pointless, it wont work at all.

Why is that?

I got confused reading the posts, I'm considering on getting e90 drop hats but I can only get the 10mm drop from removing the spring pads upfront? Any downside to doing that?
