Default Driveshaftshop WRX Driveshaft & GTSpec Subframe Install

Driveshaftshop WRX Driveshaft:


1st thought was this is a big son-ova-beech. Because its aluminum it has to be... its definitely considerably lighter. Fitment was a non-issue EXCEPT for 3 clearance issues due to the diameter of the shaft:

Clearance issue 1 & 2:


Solution to Clearance Issue 1 & 2:




The hammer is always victorious:


Clearance issue 3:


Solution to Clearance Issue 3:

Unbolt and remove clamp:


Re-install clamp and refasten:


Overall, it was a fun install and went pretty smoothly/easily. I had no balance issues or vibrations post install... the car drove virtually the same and I took it to various rpms/mph combinations from idle to 8k, 1 mph to 120 mph. I will climb under and inspect in a few days.

GTSpec Subframe Install:

They are beauties-

Too bad they are under the car... and yes I need a new swaybar, lol!

Not much to say other than the driver side piece needed two washers on the back bolt for spacing (bolt just above "20" in "2006" in the pic). And the passenger side piece is not compatible with the O2 location of the TXS bellmouth downpipe. Easy fix... just have another bung welded in.

Easy install... excellent fit and finish... one heck of a piece of work... highly recommended.

Both mods get 2 thumbs up Better stronger lighter... how can they be wrong?

Special thanks to Andrewtech and James for getting the shaft to me so quickly and at a good deal... to MTS (Maryland Turbo Solutions, marylandturbo.com) for getting me lift-time on short notice for the install and a deal on the GTSpec subframes, too. Thanks Rob!

I got severe vibration from my Driveshaft Shop aluminum driveshaft from about 60-65mph. That was on an 04 STI, though.

Have you had any issues with vibration?

I've often wondered if the lightened driveshaft was worth it, and I'm glad to see someone went out and installed one. Are you saying that the car still feels the same after installing it? :O

The main reason i was considering the one piece driveshaft was to eliminate the drivetrain slop. The carrier bearing is soft and seems to flex quite a bit. Did you gain any more of a solid feeling from this mod?

I'd say, yes, drivetrain slop is diminished.

Again... I will post more soon.

I do not have vibration but i still have rubbing upon hard right or left turns at low speed. Also, at high speeds, letting off the gas the trany twists and i get rubbing. I NEED new, hardend trany mounts but noone makes auto trany mounts so i have do diy mod.
My friend Andy/Xotic also installed his and had better success. We both noticed overall improvments as formentioned in this post.

I have no problems with mine but I did cut out a chunk out of the floor area. I do rev up a lot faster.

I heard that a one piece drive shaft will put a load on your rear seal on your tranny and will cause it to leak. Any info on this would be great I want to get one for my car to go with my 6 speed.

Ok... so here's the scoop:

My shaft was PERFECT... not a single grind, vibration or ANYTHING of that matter to complain about.... well, until I hit 130+ mph anyway.

At this point the most awful grinding/vibration came from under the car... near the rear. Now mind you these speeds are what I see when running the quartermile. I keep into just past the traps...

Upon inspection, I found that the driveshaft was hitting the rear diff carrier which ground a 1/4" wide 1/8" deep groove into the shaft.

This area had been modified. A LOT of material had been removed and the clearance there should have been enough that there should not have been an issue.

Anyway... I was told to rotate the shaft 90 degrees to see if this made the problem go away.

I have 2 problems with that... 1) the shaft I have now is damaged, and 2) testing this would require another journey to 130+ mph (with a damaged shaft that MIGHT become more damaged).... not something you just do for the heck of it, especially when you are looking for a problem... any problem let alone a problem with a 12 pound 4 ft long aluminum shaft spinning just below and behind me at REDICULOUS rpm.

So... needless to say, they are sending me a new one. I am swapping in the new shaft soon... installing a new clutch and then heading back to the track. Hopefully I will have no further issues.

That is all.

Hopefully it works out for you. Afterall, if we don't get 10.9 out of that sz49.. Well, if you value your knees, it'll happen. Know what I mean?

omg, you got them to send you a new shaft. nice. mine is def chewed up alittle bit but i feel itwill be ok. But i certainly have the same concerns as you. i hope its not a time bomb and did not make the shaft weaker in any way. I dont think it did and after i put some tranymounts in it should be fine.
