Hi everyone, starting to get things lined up for my upcoming GT4. I searched on wheel offsets so I can pick out some street wheels but it seems very odd. What I saw referenced was ET61 for the front and ET50 for the rear. The front seems very high... Please see below for comparisons I used;

Cayman GTS 20" - Front ET50, Rear ET50
991 S 20" - Front ET49, Rear ET65
991 GT3 20" - Front ET52, Rear ET49

Do I have the right measurements for a GT4? Trying to see if any currently available wheels would work.

I saw the same offset referenced on Suncoast.

Wheel Dimensions:
- Front 8.5" x 20" - 61mm offset
- Rear 11" x 20" - 50mm offset

Whatever you do, make your life easy and get offsets that are close to stock. This way, when you flip flop between your street wheels/tires and your track wheels/tires you aren't flip flopping spacers as well. Obviously wheel studs and lug nuts would make all of this as painless as can be but if it's a street car and some folks don't want those, which we understand.

Shoot, was hoping it was a typo for that front offset...Means I can't leverage using a rim from another Porsche model and have to wait for one to be built for the GT4.

While we are on the subject what length of wheel studs will work for the GT4?
