I'm reaching out to the forum community to see if anyone knows if the following wheel specs would fit the 718 GT4 since my car won't be here until May. I purchased the wheels for my 987.1 and was hoping I could use it as a spare set for the GT4.

The specs are:
Front 19x8.5 5-139 ET54
Rear 18x10 5-130 ET40

I'm looking at it from more of a functional perspective rather than an aesthetic though I'm hoping it won't look too bad.

I forgot to add, this would be with standard brakes.

Thanks!!

So i found this site that let's you do an offset comparison and it seems like my wheels shouldn't be a problem. They're definitely going to be on the thinner side.

Front Comparison


Rear

That's assuming I entered the numbers correctly.

Can you confirm the specs you posted? I assume you meant:

​​​​​​Front 19x8.5 5-130 ET54
Rear 19x10 5-130 ET40

And when you say functional, in what way? As a winter set or a track set?

Yes, what you have correct. Thanks for catching that. At my age, fat fingering seems to be a common occurrence.

As for functional, I'm talking more about winter driving. I would imagine stock would be better for tracking anyway. I was more worried about fender, suspension, brake rubbing but looking at the comparison I posted, I can't see this as being an issue.
Always good to check with the experts before breaking any expensive bits. lol

Thanks!

Just wanted to update tire sizes. Fronts seem to be right but rears are off in my previous post.

Based on my research, it seems the following size is recommended for the rear given the limited 10" rim width.


This would fit but pushing things to the limit with tires bulging out.
