Will 305/30R-20 fit Sport Design wheels?
I did a search and could not find a definite answer. I am talking about the sport design wheels (not sport techno) that came with my narrow body S. My current P Zeros are going to be more than four years old and I am thinking of replacing them with Michelin 4S. I believe the new N rated ones will only come with 305/30R-20? Shall I also get the Porsche 5mm spacers while doing this?
Thanks. If previously discussed, please show me the links to those threads

Why not?
My car came with 5mm spacers from the factory.... and even then, they still aren't completely flush. Spacers are fine and yes, to get a good looking fitment, you should get 5mm spacers. I'm about to put mine in classifieds if you're interested. $150/shipped for 4.

So looks like narrow and wide body wheels are both 11.0" and can take both tires 295 and 305.
Offsets are more aggressive in wide body.
Not like spacers would be necessary on a 305 tire on a narrow body wheel. 5mm spacers would make them look a bit better though. Need longer lug bolts though.
Tires are only a 3/8" difference total. Split that to either side of wheel.

^^^ Yes STG, that was what I was thinking. Though the wheel for the wide body has a ET52 while narrow body has ET70. I believe ET is for offset. So, it looks like for the narrow body, the wheel is more sunk in. If I put the 305 with the 5mm spacers, then it should actually work perfect by pushing it out a bit and counteract the slight sunk in. I hope I am clear with the concept

The more aggressive offset is to push the wheel out because of the wider 4S/GTS body.
Not like a 305 tire on a narrow body wheel will rub on the inside or anything. That being said, adding 5mm spacers will make all wheels look a bit better pushed out slightly.
I'd do 305 rears and add 5mm spacers on all four wheels. Remember longer lug bolts though. The 5mm "kit" on Suncoast comes with everything.
