These are a great product as I they give you lots of adjustability on camber and therefore scope to get lots of caster. It tends to be the case that the max camber will be 0 degrees with a standard setup. They also do well in my targa car putting up with plenty of punishment.
After I put one set on I put the car back on the ground without changing anything and took a picture to show the difference in what camber is available. This car was 0 at max camber before changing.
