Default Help with suspension for 08' WRX

Hi,
I'm looking for some input on suspension upgrades. 08 WRX. Here is what I have so far for suspension and other "stiffeners"
225/45R-17 Dunlop Direzza ZII
GTWORX/Bilstein shocks/struts/springs from the initial order
RCE lowering Camber plates (going back on after repair)
RCE Front/Rear Sways
Kartboy front end link Rallitek rear end links
Whiteline rear subframe inserts
Whiteline Rear diff bushings
Whiteline Steering rack bushings
Group N transmission mount
Kartboy pitch stop
Grimmspeed Master Cylinder brace
Shifter bushings front/rear

I'm will be adding an ALK and the front LCA inner bushings. The last time I had the car aligned the tech pulled on the wheel and control arm and either the rear bushing or the ball joint had play. I can't remember which, but will look when I put new rotors on soon. What do you think about adding a roll center adjustment kit at the same time or just OEM ball joints if they are bad. I usually get to 6-8 days of HPDE's per summer. The car is pretty stiff on my local "bad" roads but I don't mind--it's very fun on the track. I was running about -1.8 front camber with the camber plates and can only manage -1.4 with 09' top hats. My rear camber has been high and I eventually will add something to get it less negative.
With the RCE/Bilsteins and the camber plates my drop is about 1 inch. I'm feel some "twitchy/wobble" over bumps and the car doesn't feel as locked down as it used to be. Thanks for the help.

I will post the question to Turn in Concepts. I also have SS brake lines, Ate fluid and run Carbotech XP10's at the track. I have only read one post on a fender brace for the 08+ WRX body style. Is there anyone else with experience in the GT-spec brace. This seems to be the only one for this body style GH/GR

Definitely have a nice round of mods there. I would say you could replace some of the rear suspension arm bushings as well. With a 08 that has seen more spirited use as it sounds like your's has, there is definitely room for improvement there. Rear trailing arm and upper inner rear bushings would be a nice upgrade. You will reduce deflection and in turn dynamic alignment change which will result in a more predictable feeling rear. You will also gain some rear alignment adjustment capability.

The Roll center adjuster kit will be a nice addition as well. Not only will it sort your potentially (and likely) worn ball joint, but it will help correct roll center geometry as well (and quite nicely) for the amount of lowering you have on those springs.

Here's a link to the parts you mentioned you we're interested in, as well as the one's I mentioned: http://www.vaughnperformance.com/cat...on/Accesories/

If you have any other questions, drop me a line, I would be happy to help.

-Anthony
