I have heard 04 guys can use WRX housings and then use Koni's
But so far I have found no real options for upgrading the shocks for A-Stock on a 05 STi.

A-Stock allows you to change the inserts but you cant change the springs, ride height or mounting position and I think the travel of the suspension needs to be the same.

Anyone found anything that works for an 05 STi?

 

I believe the Koni Inserts are acutally shorter than the stock struts... What you can do is acutally convert your Stock Struts into Konis... It's called a "wet kit" We have a lot of west coast STX drivers that do this option... Either in a Single Adjustable or a Double Adjustable application. They would be built to stock specs so it would be legal.

Single Adjustable Wet Kit Conversion - $400.00/Strut
Double Adjustable Wet Kit Conversion - $ 550.00/Strut
