I assume that the extra length on the STI front axles didn't cause any problems? I am just about to drop my transmission in and I'll be using those same axles with the stubs changed over.
Jeff, what's your plan for changing the stubs? You're planning on using a wrx 5 speed with sti axles right?

I am using the STI axles with the STI Rear Stubs (outer), and STI Front Inner Stubs. I had my 5 speed converted to accept stubs by Andrewtech during the buildup.

We had one on our dyno last week and really didn't see a huge increase in power over an AWD application. It was maybe 5% higher if i remember correctly.

The tune is based on 91 Octane from Safeway

Jeff - Yes, i used the STI axles as you described. I ended up adjusting my links so i have at least a 1/4" lateral travel in the axle to ensure there was no binding.

Awesome. Great to see your car making noise! I may have to come up and see it in person.

You are more than welcome to. Working on mounting the passenger seat in.
Im also going to attempt to install and integrate the STI center console. It looks very promising.

I have no issues with it per se. The dyno could just be decoupled though to run just the rear.
