May be possible, but one would be forfeiting his factory engine warranty. Even the dry-sump cars are very clear about this restriction (no slicks on GT3 or RS either).

When folks say "slicks" what specifically are we referring to? IOW, does "slicks" include something like Hoosier R6/7, or are we putting these more in the R-compound category, meaning slicks refer to true racing rubber? Just curious.

The Clubsport has the same calipers, pads and rotors as the 991 Cup....mfg by
Performance Friction. Looks like the hats are different than the 991 Cup.

Slicks are not street legal. Something like a DOT approved Hoosier R7 is R-Compound, but not a "Slick".

It's possible that the difference in the hats may simply be to account for the 5-lug hubs, rather than center-locks.

How's this for technical info:
Warning:
Don't flick your cigarette out of window while driving
GT4 Aerodynamics likely to result in cigarette getting sucked into side intake flares

Not sure how they would know what tire was one the car - does the ECU keep track of max Gs? Agreed that R7s, once up to temp, are a new sort of magical substance. They are about as close as you can get to a full slick, like a medium/hard compound. My first set of 19s will be shod in these

The GT4 Owner's Manual probably does ban the use of Hooisers. Sure Hoosiers are DOT tires, but Hoosier clearly calls them Hoosier Racing Tires and advises NOT driving them on the highway--the sidewall is not substantial enough.
Hoosier:
NOT FOR HIGHWAY USE: All Hoosier Racing Tires including DOT labeled Hoosier Racing Tires are designed for racing purposes only on specified racing surfaces and are not to be operated on public roadways. DOT labeled Hoosier Racing Tires meet Department Of Transportation requirements for marking and performance only and are NOT INTENDED FOR HIGHWAY USE. It is unsafe to operate any Hoosier Racing Tire including DOT tires on public roads. The prohibited use of Hoosier Racing Tires on public roadways may result in loss of traction, unexpected loss of vehicle control, or sudden loss of tire pressure, resulting in a vehicle crash and SERIOUS PERSONAL INJURY OR DEATH. Exception-"PRO STREET"
Porsche:
Racing tires
The fitting of racing tires (e.g. slicks) [emphasis supplied] for sporting events is not approved by Porsche. Very high cornering speeds can be achieved with racing tires. The resulting transverse acceleration values would jeopardise the adequate supply of oil to the engine.
Porsche therefore refuses to accept any warranty or liability for damage occurring as a result of noncompliance with this provision.

I wouldn't put words in Porsche's mouth, even Hoosier's own warning to cover their own butt.
This one is simple. If it is DOT approved, it's a street tire. Porsche can't reject a street tire. A Hoosier is a street tire.
