Hi Folks, does anyone know the Geometry settings (Front and Rear) for the MY05 WRX PPP (55 Plate)?
Our laser alignment equipment only lists upto 2004 currently and I wasn't sure if there would be any changes in spec.

Also has anyone actually adjusted the front Camber, is it the same as the rear (Loosen the nut and turn the bolt with the camber wheel on)?

Oh...and finally...Is the spec different for PPP, or should I keep it standard as afaik no modified suspension parts have been fitted, just the ECU, IC Piping & Exhaust parts?

BIG Thanks...D-an-W

 

The rear isn't adjustable.
The front is as you describe, top bolt is the camber bolt.

Sorry, when I said "Same as rear" I was reffering to the method for adjusting the Rear track...

 

ahh ok, yea similar idea then, turn bolt to adjust.

I set the rear track to Toe Out 0deg 3mins on each wheel and the front end to parallel, does that sound about right (It was the 2004 Spec I used)?

 

It all depends from what you want from your car.
I suggest you max - but same left/right - camber front with factory rear and about 5-6 mins toe out front AND rear.
This setup is similar with what Group N cars use with less camber of course(due to limited factory adjustability) and gives you pointy front and happy tail car IF you like of course!

To be honest, I just didn't want it scubbing tyres prematurely. You think what I set it to will achieve that?

 

Toe out?

I'm really not passing judgement on your capability but I found this to be far too much in the wet, and I really wouldn't recommend it unless you really are comfortable in what you are doing.

 

same here....

toe in keeps it stable and less snappy imo

The Spec on our alignment equipment was -0.03 (3 minutes toe out) on each rear wheel and parallel on the front wheels which is what I set it to. This gave a thrust angle of 0 degrees on the rear axle also. Everything else was within spec so I left alone for the time being...

 

No problem with premature tire wear I always have the outside of my tires worn more than inside but toe out gives you always more "nervous" behaviour and depends from your driving skills/style if you'll drive better or worse with such setup, I passed all the "phases" in my classic shape turbo from Prodrive's settings "toe in only rear" to Whiteline's "toe out only rear" and now to Prodrive's Group N setup "toe out front-rear" in my WRX MY03 (actually 4mins toe out front 6 min toe out rear).
It's a really difficult to answer question which setup is better for every driver and I am not a professional, just try to delete every small amount of understeer from my car!
