Nice rims, I bet those would looks sweet on a Boxster. I also concur it seems like a good price for 19"s, it's sux that the set of tires would cost you more than the rims.
The only thing to me is that the set doesn't appeared to be staggered as it is listed as 19 x 8.5.
You
need 9.5 - 10.5 in the rear....at least imo.....
