Default HT Autos STI side skirt extensions

2003-2007 "newage" WRX - which is 2004-2007 with the STI style skirts for us USDM folks. The pair is made of black polyurethane and includes some install hardware. No instructions provided.
http://htautos.co.uk/shop/subaru-imp...irt-extension/
I was unable to find any useful part detail, issues, or installation posts when I was considering purchasing. So I finished installing these on my WRX and thought I would post something up.

Package Contents - they are lengthy so two excuse the two photos


Top side closeups



Bottom side closeups



Hardware - it's useless



Purchasing:
I'm 85% positive the US distributors are not keeping inventory on any of these. Basically you order from someone in the US it's still going to ship international from the UK. Personally it irritates the crap out of me that distributors do not disclose that. Looking back I probably could have saved some money just going with a direct purchase from HT Autos. I had compared the shipping between both sources, figured import duty was unlikely, but C Card currency fee was likely. Either way shop smart and you should be fine.



You want info on the matching rear lips?

The installation was not simple so I'm still working on how to best describe what it took................
Since you have to remove all of the lower push clips I recommend pulling the skirts off the car and working on a bench. It beats laying on the garage floor.

Remove the rear splash shields. These are meant to redirect air around the rear tires for improved aero.


Obviously these are not going to fit once the skirt extensions are installed so for now leave them off. They are likely only effective with OEM width tires. Many of us have moved away from OEM width and offset tires/wheels. Most of us would not even notice a difference either way. I suppose some larger shields could be found to mount directly to the extensions if you were so inclined.


This is what their hardware is meant for? Yea that's not going to cut it for my install.


Perhaps this is not exactly the orientation they mean but with NO instructions how the heck are we supposed to know. Anyway you put those in...it's still poop.


I used the holes in the skirt and extension as my location reference. Then had some clamps to hold things into place while I moved down the part.


When I got to the front, wait what the #$%^&* is this?


The extension will not sit flush to the skirt and the push clip holes are very much out of alignment.

Sort of difficult to get a good photo that shows where the conflicting fit is occurring.


After some handy grinding away of extension material it now sits flush onto the skirt. In this photo you can sort of see how the lines now "just" meet up.



I cleaned (multiple times) all of the mating surfaces with alcohol and allowed to dry. Then removed the film from the adhesive tape and pushed the extensions into the skirts. After that I clamped them into place and let them sit for a few hours to adhere. No photos of that but you should be able to get the point.

Instead of the included hardware I went with alloy pop rivets and backer washers.


Started at the rear holes working my way forward adding a few extra rivets along the way. Ended up with a very solid attachment.


Now just snap the skirt back onto the car and focus on the lower push clips. My car was built with 909140020 push clips and some of them would not snap into place. Seemed as though they were too short. I found these other push clips 909140055 which specs showed an additional 2mm of length. Dang they cost 3x as much too. After arriving these did not seem longer at all but they did clip into place fine. I believe that my original clips being used were my real issue here.



Installed



Opinions:
I am using HT Autos' rear lips and a Vltd front lip so something between made sense. Since I have a 2006-07 WRX, it's sort of the red-stepchild basically STI side skirts and a WRX rear bumper. The version of skirt extension to fit my side skirts have to be designed around the STI versions. Honestly they effed up the mold design on these in a way that looks fine but really makes the install a pain. I about feel that I should have gotten these free or at discount for the install hassle and providing a realistic review instead of a fanboy fluff job.

Thanks dumb mold

The perfect extension that I have been looking for a while now. Any thought of adding their diffuser?

I thought the 2004 STI had the blocky WRX style side skirts though?

No not the one from HT Autos.
I currently run an OEM Subaru 2006-07 STI rear diffuser but I'm contemplating installing the HKS Kansai type diffuser I bought awhile back. Let's be honest, rear diffusers are all about how they look on 99% of the cars you would see them installed. Nearly no one installes rear diffusers in a manner that serves a true aerodynamic purpose. I personally do not find the HT Autos GD rear diffuser aesthetically pleasing and it completely covers up the rear tow hook. I also do not think their rear diffuser could possibly reduce tire wash from occurring with those shallow vanes. Mearly car show fodder...

Mine have the same as yours. I know the WRX have the blocky style.

Thanks for the input, I was curious. I agree with the diffuser too serving little purpose of true aerodynamics. I have contemplated getting the Subaru OEM diffuser to add a bit to the rear. I did not think however about it covering the towhook, but I also haven't planned on going into a ditch anytime soon.

Ahh I see on the skirts.
I am still of my opinion that a rear diffuser on any street Subaru (and many weekend track Subarus) are all show and absolutely no aero advantage at all...likely more disadvantage. You rarely see them installed correctly let alone accompanied by a proper flat bottom. That's even before you start thinking about what they are doing on top of the car too.
I also don't think anyone plans on going into a ditch, at least I hope not. I do see how someone might install that then find out later that the tow truck can't hook to their car to get them out.

Thanks for doing this. I am looking to buy these and I couldn't find much info on them. Do you have any pictures of them with all the lips on the car?

Not yet, car is confined to a garage until spring. I will eventually update both review threads with an overall photo.

Good info here. I do plan on purchasing these after i find some WRX side skirts. I don't like the design on the STI side skirts of 04-07, they just look out of place. Only time they look good is if you were to run chargespeed extensions - but even those look out of place if you don't run the rear spats.

Thank you for the detailed review/installation.

If you have plans on installing the HT Autos diffuser, I suggest you it the toe hook hole as well as a rectangular shaped for the box circled in the second picture. It creates fitment issues, and makes it "sag" on the passenger side. Very very low quality mold and build. But i do like it over the OEM diffuser. I have yet to clean the fins, it's been about 3 months and it doesn't nearly pick up debris as I expected.

Btw, the diffuser is two piece, and this was the right piece.
