Base GT wheels on a PP - Is it possible with spacers?

[tomnelsonii]

Hi Guys,

I know this is going to seem like a silly question, but with the correct spacer on the front, could you run base GT wheels on the PP model? Is it just the caliper that will not clear, or is there an issue with the diameter of the rotor as well? If it is possible to run the base wheels, what is the thinnest spacer that would work? I did a search but couldn't find the info. Thanks in advance guys!

The inner barrel of the wheels won't clear the caliper.

Ah, okay... so it's not the width of the Brembo caliper. The issue is that diameter of the larger rotor, combined with the space required by the caliper won't fit inside the wheel? Is that accurate? Basically then, no 18 wheel would fit?

Its the inner diameter of the wheel barrel that needs to be able to have 18.75" to clear the PP calipers

My understanding is that there are also issues with clearance between the caliper and the "spokes". How about the premium 20" foundry wheels? I've been seeing good deals on rims and tires and I'm trying to figure out what will and won't fit.

They can work, here is why

The GT PP is a tall caliper but its flat, The GT caliper is short but the housing is larger, now I have seen the foundry on the GT and it works so I believe they would work on the GT PP as well.
