I have an 02 and 06 rack that I am depowering. This means to remove the inner seals to free up the traped power steering fluid, which gets u back to the steering ratio that the rack was designed to produce. If you don't do this your steering input is going to be more difficult in quick transitions and your ratio will seem higher. Miata race guys do this often and it will benefit us 818 guys. Open for questions,
In process of bead blasting, and powercoating spindles, brakes , control arms, sti wheels and various brackets etc to install the new bushings and seals. I have a set of brembos off a sti, but I am really think their overkill so I am rebuilding a set of wrx 4 pot brakes.
