Do some research on those CUP tires as they will only

increase the load on the suspension.

I'm really questioning these guys smarts if they recommend 19" with stickey tires on a 97 with a known to be marginal with 18s stock suspension. If only you had a '98 as it was then that the suspension was strengthened.

Also as you go up in wheel size, you use a tire with less crush space. So, when your tire hits a bump, pothole or whatever, the space the tire can crush to absorb the blow before the expensive wheel gets involved is less the larger the wheel you use. And if the tire runs out of crush room, it gets pinched between the hole/bump and the rim and the tire gets cut. So if you are going to use these wheels on your Boxster, you'd better be from an area that has awfully smooth roads or you'll be making repeated painful $ acquaintances with one of the wheel repair places at beyond $150 an incident (if it can even be fixed) and with the tire shops.

What exactly changed on the 98'+ suspensions compared to the 97'?

Very tempting, I would likely go ahead and do it, though I would find some way to strengthen the suspension and stiffen the chassis a bit to make up for a somewhat older, flexy car which now has a lot more power.

Also, the price of labor here does seem a bit high. You better get one hell of a nice job done for that price. Should be amazing though at the end of the day!
