Outer tire wear - what to do?

[steve_wilwerding]

I'm finally getting pretty decent on the track during DEs (on street tires, anyway). I came back from this weekend's track event and pulled off the wheels to change the brake pads back to stock from the Pagid Oranges, and noticed that my tires were worn pretty well on the outside, but hardly at all on the inside. This was true for both the front and back tires, but seemed to be more pronounced on the rears.

I'm assuming I need to be running more camber. My 98 Boxster has never been aligned since it came from the factory, so (barring a little difference after ten years), the camber should be stock.

I'm trying to figure out the best way to add more negative camber. I could go with camber plates, which are probably the cheapest option, but they raise the ride height of the front of the car. I could get GT3 lower control arms, but they are rather expensive. I could go with the ROW 030 kit (I currently have the US 030 kit on the car) or get PSS9s, both of which allow about 1.5 degrees of camber on the front. The other option is to dremel out the stock mounts, which I've heard a lot of people talk about but never do.

Which is the best, most cost effective solution?

Yup, you need more camber. The "factory alignment" on my car straight off the boat had POSITIVE camber on the right, 0 camber on the left and a whole bunch of toe-out. Porsche must have thought I wanted to go circle track racing...

Either the ROW or PSS9's will help your camber problem at the track without compromising your street wear too much. Do not use camber plates on an otherwise stock suspension. It kills the handling of the car. Ask me how I know!!! <_<

GT3 control are work but as you said, they are expensive. Dremelling out the upper mounts? That's a complete hack. Can't recommend it.

What I would recommend are the PSS9's as they give you the ability to corner balance your car and you can stiffen them up for the track and then back them off so you don't lose fillings on the street.

Good Luck
