This is an opinion board. Anyone who cant distinguish that much on their own needs to stay off the internet at all costs.

For Porsche to say "No Slicks" is quite telling. They are not likely to be honest about why either. So its likely that we will have to find out from another source.

You're also talking about a company that positions virtually all of their print and video marketing for the car in a track environment (see all videos to date except the late to the game "Emotion" and every photo in the hardcover book) while at the same time voiding the warranty as soon as you drive onto a track.

Any corporation says whatever it wants, whatever marketing lies about has 0 to do with what sales department and legal enforces on their customers. Different departments, no connection whatsoever. Complain to VW if you want, but - ...

Some of us come here to learn something. Stating your opinion as fact is counterproductive to that, and to the board in general. $.02.

I dont really care. If the original statement is true the writing is on the wall. No matter the abundance of denial. The educated will generally come to the same conclusion based on the evidence at hand.

Like I said, if someone expects nothing but facts on a car forum, they are sorely misguided.

I have seen 991's in race trim. From chatting with some of the teams running them, the modifications are relatively minimal - engine is fine actually.

I think the gt3 issue is with the trick suspension. Think about it, you've got an electrical mechanism that is working AGAINST the grip-G in some cases to hold a particular toe angle. Increase the grip and you need to increase the power of the RWS. It seems straightforward to me (albeit appaling)

lets see. First deliveries very soon...

Completely agree.

BBMGT3,

This is why I posted the aforementioned. I really doubt the 991 3 has oil starvation issues.

If the RWS proves to be the reason as suggested, well they should have gone without it because I'll bet my nuts a set of slicks would allow the car to lap the NBR way faster than the RWS and no slicks... I've got the feeling that the RWS will end up being like the CL debacle of the 997.2 cars amongst the track guys... If there will be any such guys...

wanna911

It must be really bad if they are all out saying no slicks. With the CL, they at least put their money where their mouth was and ran a CL version in the 24 hr race.

Slicks are ultra sensitive to toe changes and will blow out on you in a second. Now that I think about it, it's akin to an issue that myself along with several other 996 TT guys have had. Fine static alignment specs, but too low of a ride height on the 996 caused too much toe out under heavy loads. Slicks blew out within a day if not a session or two (Michelin, Hoosier, Yokohama). DOT slicks lasted much longer and treaded R-compounds life seemed almost normal, with a little toe tapering. Feasible RWS could cause a similar scenario and slicks blow out.

a logical thing to presume would be if this car matches chassis of a 2013 cup then probably a sound thing to do will be to move entire cup`s rear axle suspension into this gt3 chassis, but it will probably cost ungodly.

When Porsche published the GT3's NBR times there was an insistence on needing more data, needing segment times, factory figures were suspect, factory drivers were sandbagging, etc. Need more facts before conclusions can be drawn. No one should assume anything positive until we have facts. We're data guys.

One single post and a lot of ifs later, though, negative assumptions abound about this subject.

Curious. It may turn out to be true. Just saying'........

If RWS proves to be the reason as to why stickier rubber isn't allowed, I would argue that this is the first legitimate argument against one of the 'improvements' made to the new GT3. That being said, I only plan to use oem tires or oem type of tires for the track anyway.

I'm still curious if an R6 type of tire is 'not allowed'...

Manifold

Speaking of tires for this car, I've used the Dunlop Sport Maxx Race on a Cayman R, and found that they have decent grip, but they can't withstand serious track use. I've corded several of these tires at inside or outside edges, and camber changes didn't prevent it. NT01s on the same car with the same alignment had no problems with wear. Maybe the DSMR will hold up better on the 991 GT3 ... or maybe not. And hopefully the MPSC2 will do better.

It's too bad nitto isn't an oem supplier...
