I have a 19GT PP2. I need to know what sizes and off sets are able to fit with no issues. I believe the fronts are more of an issue with the larger rotors and brakes.
The PP2 has the same brakes as the PP1, so there are a lot of options that will fit. I have SVE R350 19x10 +35mm wheels for my summer tires. They also make 19x11 +50mm offset as well. SVE has a lot of different styles in the same sizes.
I also have the Michelin A/S3+ and they are very good performance all seasons - I put them on my factory PP1 wheels for the winter. I use the R350 w/ PS4S for the warmer months.
