I ran them at Thunderhill last Fall - too cold and wet at the event this last weekend. I really like them, great grip (do need camber to make them effective), manage heat very well, although I've been quite impressed with the N1 PZeros at the track - much better thermal properties than the N0 - manage to run 1.56 at Sonoma with a passenger in the fall with them.
I ran the TrofeoR's on my 991.1S so the tread was rather worn down, will need to purchase a new set in the next month for this year, very happy with the life of the tires also - depends happy badly I drive or how well I drive :-)

Thanks. I track w/ a pro instructor who also thought the new Pirellis were a big step up.

Both the HRE R101 and R101 LW's will clear PCCB in 19's and they weigh less than 20 lbs per making it one of the best track day wheels if not the outright best.

Street: Stock 20" wheels sporting MPSS
Track: OZ Leggero HLT wheels sporting Toyo R888R, moving to Hoosiers this season
Pads: Pagid RS29 (yellow)
Rotors: Gyrodisk up front, Sebro in the rear (all slotted)

For reference, my front brakes are the same as the Turbo steel brakes, and the rears are the same as the 996 fronts.

My 991.2 C4S w/ SPASM, Sport Package (RWS & sport exhaust) runs on sport cup 2s and RS29s with excellent results on a track alignment. I run 20” on track and 19” wheels from my 997.2 I kept for rainy track days. I recently upgraded to GiroDisc rotors. Front rotors fit with my existing caliper studs but the rear rotors is another story.

The rear caliper spacer pushed the hard brake line mount into contact with the wheel. I wish I had noticed before I turned my brake line bracket into an aluminum lathe for the inside of my wheel. Back into the garage to assess damage, no terrible but I have a shinny racing stripe inside my wheel. I put my 20s on thinking a bit more clearance might do the job. No, glad I didn’t take my nice wheels for a test ride on the GyroDisc lathe.

Anyone with a similar experience? Any positive experience with a hard brake line delete on the rear wheels? Something like a stainless 6-line kit from Spiegler or GMG? I’d like to make the Gyro’s work...

Could try bending the hard line mounting backet and line inward to give yourself more clearance.

I have the GT3 6 piece spiegler kit, but I don’t have 19.
Good fit for the car.

The 19s are Okay, they're the same size as the winter tire package so I knew they would fit and I figured I'd have more track tire options on 19" rims than 20s although the 20s look MUCH better than the 19s.

I thought about arter's suggestion of slightly bending the brake line and mount but didn't want to push my luck yesterday...

I have braided lines on the car already which is what mead me think of the Spiegler caliper braided piece to add into my setup. the bracket will clear w/out the brake line attaching bits and pieces. 11 days to get sorted before my next track day; looks like I'll be making some calls tomorrow to get it sorted.

What is the offset on your 19”?

I ordered a set of Forgeline 9x19 +40 and 11.5 x 19 +70. This should keep the inside away from anything on the inside but will look at my brake line mounts and interference. Thank you. OEM are 8.5 x 20 +49 and 11.5 x 20 +76.

I changed to the Spiegler 6 line set and ran Pagid yellows front, couldn't get rear. Ran SRF fluid. There was so much heat it turned my stock red GTS calipers Brown. Disintegrated a brand new set of rear pads in 3 x 20 min sessions.

I have since up graded the whole system to a Brembo BBK GTS. 380 mm front and Rear. They come with FM 1000 pads. Awesome for street. Used 50% front pad first track session but only 10% rear. So the 380 in rear made a huge difference. I have ordered Endless ME20 for front and MX72 for rear, and I should be able to run that on the street and track. MX72 are silent. ME20 not much squeal on street, but epic on track.

I do run 20 inc wheels. I split a Cup2. So they are not up to heavy tracking, although they were a huge imporvement over the Rubbish OEM Pirelli. I have since changed to TrofeoR and love them. Huge step up again.

I have full Tractive coilovers now with the adjustable top hats and Elephant racing control arms. I am currently running -3.2 degrees camber in front.

Cup 2's aren't up to "heavy tracking"? That must be news to the thousands of GT3 owners who've been on them since 2014.

The question was asked what they are like on point 2 which is turbo and way more torque than a GT3. Especially tuned ones. Fast GT3 guys will know the cul2 is not up to it. Sidewall is way too soft.

They are more than enough for cars and coffee guys and slow guys.

19s from my old Targa are 8 J x 19 RO 57 and 11 J x 19 RO 51; I also have snow tire setup on 19" 8.5 J x 19 RO 50 with 11 J x 19 RO 56. My 20" OEM Spyder wheels are Front axle: 8.5 J x 20 RO 49 with 245/35 ZR 20 (91Y) tires Rear axle: 11.5 J x 20 RO 56 with 305/30 ZR 20 (103Y) XL tires

For the average GT3 / GTS driver they are just fine. To broadly dismiss them as "not up to tracking" I think is a bit severe and incorrect. I have probably run through 20 sets on track in various GT cars on track including a tuned GT2 (which was pushing 600ft/lbs at the wheels). They did not spit or fall apart and I would not characterize myself as slow. I had the tread separate on one early one and Michelin replaced it.

Yes, if you are racing or trying to set ultimate lap times, I would probably not run them. To insinuate they are not fast or for "cars and coffee" drivers is laughable. Maybe tell Lars Kern that.

First off don't change my words. I clearly said they are, "not up to HEAVY tracking." You have now changed that to, "not up to tracking." Of course they are fine for the average guy. I found them an excellent street tyre.

2nd, I don't need to insinuate they are not fast I have proven it myself. Everyone in our track group that made the switch, including myself is an average of 2 seconds faster on TrofeoR than cup2. I can now conclude that cup2 are not fast. Not insinuate, but have proven it. Chris Harris found the same thing. Maybe you can tell Lars Kern that.

Many people on the board told me that the stock brakes were more than enough. Many touted that instructors and race guys said the same thing. Mine went Brown. Are your calipers brown?

I have run Cup2 for many years on many cars, but this highly modded and tuned twin turbo GTS ripped them apart. The sidewall is just too soft. There is a youtube video of a guy showing how soft the sidewall is compared to an AR-1. The cup2 sidewall is floppy. I look forward to the Cup2-R which like the TrofeoR, has a much stiffer sidewall.
