I am having the Prodrive springs fitted to my Sti8PPP as since having the car PPP'd I have noticed it tends to understeer more due to the increased power avaialability.
As the UK car doesn't have DCCD-A I am keen to ensure that the dealer dials in the best set-up after the springs have been fitted and not necessarily the recommneded Prodrive set-up. I am told that the Prodrive alignment tends to eat the inside edges of tyres.

What would be the best settings to improve handling but without scrubbing the tyres too early? I am intending to take the car to the Ring next year as well

Thoughts and advice would be appreciated

What makes you think that our settings eat the inside edge of the tyres?

I have the prodrive setup on my car (MY99 wr sport) and there is defo more wear on the inside, even to the point of me taking it to my local dealer to get the alignment checked. Had the check & was told everything was ok, as to the uneven tyre wear was told "all prodrive setups do this due to the increased negative camber".
Hope this helps, Mike.

Our geometry setting were within the tolerances for the std vehicle anyway so a std car could quite easily show the same tyre wear profile driven in the same manner.

The biggest contributers to inner edge tyre wear are lots of straight line running, ie no hard cornering, and heavy braking as this dramatically changes the geometry, adding camber and lots of toe-out. A car used as Steve is intending could quite conceivably benefit from running even more camber to stop the outside edges of the tyres wearing out. Our demo cars never wear out the inside edges......

Mike,

Thanks for your comments on this subject. I will use your settings and see how it goes.

I don't intend to drive hard on the Ring, just the experience of doing it really. I will be treating it as a Sunday afternoon drive so that it doesn't bite

I have noticed that the standard Sti settings are beginning to wear my Toyos on 18" Prodrive rims however, so maybe I drive more corners and less straights then !!!!

Have Prodrive springs and geometry on my 01 WRX and tyre wear is pretty even across the tyre (225/40 on 18in wheels)

Good luck

Nick
