I did do Sebring last week, ran only one day. Had a problem with spoiler deployment,it did not work!
Otherwise, Hoosiers felt great. I did not get any lap times though.
A GT3RS had basically the same set up, he beat his best time 2:18 vs 2:14

I can tell you the ds2500 squeal very minimal on the street but they do squeal...most of the squeal comes from rear pads so on your Turbo since our pad size is different you may or may not experience this. The ds2500 wore out in a day and a half at Sebring and left a lot of pad build up on the disc to where I was getting vibration. The ds2500 also quickly over heated and felt mushy...brake fluid is Castrol SRF.
Then I tried the Ferodo ds1.11 and they performed better at the track but reallygrooved the rotors, transferred a lot of heat the the calipers and turned them a faded and less bright red quickly. After 2 very full days they are too thin for me to run anymore. They squealed like crazy on the street...at the track when bedded in they were quiet but on the ride home the squeal came back.
PFC doesn’t make a rear pad for the GTS...I use GT3 size fronts....Pagid has Yellows RS29 which I’m familiar with when I ran my 997 cars.

its easy...Forgeline wheels and swap out the bolt on the rear lower arm near the wheel barrel..believe it’s a Panameras part but it’s been discussed on the 991gt3 forum or Dremmel it down some....

They will fit but you have to make sure to change the tires to the right rolling diameter.

Hey David, I thought the wheel offset was different (and as a result, the fitment problem) between the widebody (Turbo S) and non-widebody (GT3) models. The tire size however is exactly the same for both.

Porsche decided to use slightly different offsets on the OEM stock wheels for the Turbo's and OEM stock wheels for the GT3's so it gives the illusion that those two cars have different fitments but they both actually share the same wheel fitments. You have a range of offsets and widths that you are able to use with any car. When you dive into aftermarket wheel options you get to see how much a car can take and how aggressive it is. The Turbo and the GT3 are both widebody 911's that share the same fitment. Same goes for any AWD 911's like the 4S and GTS.
