Another way to look at it: the 992 3 and 3RS are already so fast that there are very few people to play with at track days. Make the cars a few seconds faster and you make the pool even smaller. Sure, I can go out every session with the goal of trying to do my fastest ever lap - competing with myself - but we all know that's going to be dependent on weather, traffic, tire condition and other factors.

I get it, but I'm personally happy stock and on street tires.

I admit, I'm very curious about the Manthey 3RS kit. I can't see how they're going to make it worth the cost, in terms of lap time improvement over 2-3 miles, but we'll see.

 

I ran the stock Pirellis on my 992 3RS for 3 days at Laguna and they were ok. The best lap was 1:33 as I am just getting used to the car and its insane level of grip.

I had a 600LT before which I ran AR-1's on stock wheels for the first 12 or so days and then switched to 19" wheels with slicks and dropped 4 seconds of my lap time. I managed a 1:31.

I have 19" wheels with Michelin slicks I will be running on the 3RS and so looking forward to the increased grip. Hope to drop below 1:30 eventually.... Yes of course the car is insanely fast on street rubber but with slicks it's going to be a different beast all together. I'm not racing anyone there but I do enjoy pushing myself and seeing what lap times I can get.

 

Hydrologic, Report back on the 19" Michelin slick lap times. I recently bought a set of 19" wheels but haven't mounted the rubber yet. Was leaning Pirelli DH, but a friend with lots of fast cars runs Michelins.

 

yet you can put cup 2 r on the car, which porsche says is like a slick when it's new. looks like a case of the left hand not talking to the right (lawyers and engineers)

 

I ran Michelin hard compound racing slicks yesterday at Laguna and holy crap are they amazing. The level of grip was super high and the ability to brake super deep was impressive. I was able to shave close to 3 seconds off my previous lap times with stock Pirellis and Goodyears. I might try the medium compound next but so far I'm loving the Michelin slicks. The hard compound has a specific break-in procedure on the first few laps and then do take at least a lap or more to warm up in subsequent sessions but once they are warm they are incredible. Here are the two fastest laps. The track got warmer after this session and I was only able to do 1:31's and 1:32's


This is my 5th track day with the RS and 1st with slicks. I am still getting used to the car and of course the slicks so I see a lot of time I can shave in the future.

 

Bad idea. Buy cup car.

 

No thanks. The trade-off for slightly more safety with the addition of the front cage is not worth the hassle of trailering the car, storing the trailer, adding extra hours to my track days, hiring a support team, and paying way more for annual maintenance. Not to mention you can't buy insurance and any mishap is out of pocket. This is not my only dedicated hobby.

 

An issue for me is that using slicks voids the warranty. Though Porsche tweaked the oil flow for the RS, these engines still blow up. When they do, it saves a few bucks to have warranty coverage.

 

Been there, done that. I have more fun running slicks on GT3, just wasnt the same fun factor for me.

 

How is Porsche going to know you run slicks?

Has a 992 RS had an engine blow that you know of?

 

Slicks: Porsche may never know - true.

Blown engines: mine. No engine/exhaust mods, dealer maintained, run in per spec, tracked on street tires, 1500 miles.

 

oh damn! your 992 GT3RS engine blew after 1500 miles?? Did they figure out why? How long did it take to replace it?

 

No idea why yet. Happened October 5. My dealership has been great, ordering a replacement immediately and staying on top of the factory. We heard that the new unit was to ship today, but I gather Porsche employees in Germany have joined a strike, so we'll see.

 

Lots more safety and the driveline through are bearings is designed to take the loads caused by the significantly increased grip. From cage perspective, the Cup car cage is built through and welded - very different to a front cage addition. Slicks put strain on everything from the RAS active toe motors, bearings, suspension components, drive shafts which start to loosen etc etc.

You don't need a support team to run a cup car.

Oh and if you have a drive shaft failure its catastrophic and your car will written off. Equally your car, do what you like but understand everything is a trade off when you track a car.

 

today I spent time in the 992 cup and the 3rs on the track. the 3rs for taking some friends for joyrides, cup car for lap times.

at no point did I think - man, wish this 3rs had slicks

I think the biggest difference driving them back to back and with "max effort" is the brakes- the cup car generates quicker deceleration due to the weight difference and more aggressive ABS.

the slicks (yokohama) last 90 min -120 min which is about 3-4 heat cycles

the 3rs is cool since you can tailor the rebound/compression etc but the cup car is not much more expensive to run when you factor price of purchase. I bought my used cup for 210k on BAT. It does ~1:25's at Laguna. I'll have to go through a LOT of tires and brakes and gas to get to a GT3RS MSRP.
