Default Need help identifying springs and tophats

Hey Y'all,

I need some help identifying some parts I bought. First of all, my car is an 02' WRX sedan with Koni inserts. I bought a set of 05' STi springs before I found out they aren't a direct fit. After reading through many threads I learned that I could use 04'-06' top hats with a washer/spacer in the rear to make the springs fit my 02'.

Today I bought a set of top hats from a 04' WRX Wagon. I tried to test fit the springs w/ top hats and the rear don't seem to match. We did minimal research regarding wagon/sedan fitament and the result was positive.

So here's what I see. The rear 04' wagon top hats have a smaller imprint pattern (from the spring) than the rear 05' STi spring (spring coil is larger than the imprint from previous spring)...

Rear top hat = Smaller (coil print)
Rear spring = Larger (coil)

Are these parts supposed to mate and I have been sold something other then what I thought? Or are WRX wagon and STi rear top hats different?

Thanks for any help!
James

James the wrx 04+ rear tops (wagon or sedan) = the rear 04+ STi tops- same part #'s.

The 04+ springs have a distinctive taper (smaller at the top) vs the previous generation springs. The 04+ style top simply sits a top this tapered spring (actually a portion of the top slides into the upper coils).

If you have a large coil rear spring that doesn't taper it isn't a 04+ spring.

Pics would help.

Sounds like I've got the wrong springs... argh! Would you mind looking at some pictures to confirm your thoughts?

Thanks a lot for the help!

Can you take a side view of the top- just want to be sire it's a 04+ style?

The spring looks like it has some taper, can't tell if it's enough though.

The top should slide down into the spring and be fairly snug.

Here's what I believe to be the rear springs and top hat

James,

BigSky will confirm this, but the 'front' spring in your picture is actually the rear, and vice versa-- can you see how it's tapered?

So, do you have two 'wide' tophats and two 'narrow' tophats? If so you should be set-- just remember the tapered springs go in the back.

turn the springs around the longer spring w/ the taper is the rear sprng- you have the correct rear top and front tops- just have your springs flipflopped

Okay, so maybe I'm a dumbass

If I switch the hats, the rear fit very well with the tapered spring (as you've suggested). However, the front are way off. Is there a spring pertch in the front???

Now that I think of it, isn't this setup a MacPherson type. So there has to be some type of bearing/plate for the spring to sit on???

your not the first to switch up springs

The fronts need a upper spring perch- has three holes (beside the one hte strut goes through)- the middle of the three holes needs to face directly outward- centered on the strut. Underneath it is a rubber spring seat. On top of it nees to be a domed shaped washer- the taper goes / \

Do you have your old struts to go off of? The fronts will be assembled exactly the same.

Yeah, I have the assembled struts in the car now as a template.

COOL! You deserve a gold star my friend and have been a big help.

I thought I had them backwards (front springs are normally bigger), but the hats seemed way off. Guess I forgot that the front set MOVES and needs provisions to do so

Again, thanks so much.
James
