Porsche 992 GT3 - Track driving - Owner reviews - Page 2 - 911/Carrera GT - PistonHeads UK

Hi, I am interested to know about your experiences of track driving with your 992 GT3´s. Everything from setup, modifications, driving experience and technique etc. Here is my input and first impressions after the first few trackdays and the latest visit to the Nürburgring is that it is a completely new ballgame, at least for me having driven mainly track focused 964´s and 996´s and a 718 GT4 PDK. The speed the car builds take some getting used to and also the driving input needs to be adjusted to utilize the potential of the car. I have also tried some different wheel alignment setup but the latest one really transformed the car. If you have the time, here's is my thoughts more in detail 992 GT3 on the Nürburgring Nordschleife https://youtu.be/aIHdibO_6G8 Edited by JRN on Thursday 15th September 08:32

Great info and great driving, I get the wobblies just watching !

Top video, great driving way faster than I could do, respect. Good to see a car properly used and glad you enjoy your car.

Great review. Nurburgring is an intimidating place for me, but clearly the car is incredible capable. Second set of tyres came off mine yesterday. That wear pattern from your original alignment was very odd. Rear: Front:

Safe to say they are fully consumed!

That tyre wear; front looks okay, but rear looks something akin to insufficient camber and or slight overinflation. Geo being slightly out would result in higher temps and thereby pressure. The comments about the double-wishbone front being strong enough to cause the rear to un-stick is interesting and perhaps borne out by the wear. I was passenger in a (very well driven) 991.2 GT3 RS at Donington last month. Closely following a (nowhere near so well driven) 992 GT3, at several points you could see the rear transition to oversteer between entry and apex.

And if you don't mind me saying, very good English for a non-native person.

The outside of the rear tyre looks untouched (so rear camber is OK) whereas the front has a lot of outside wear (but still not overly uneven), so perhaps a touch more front camber would be optimal. But agreed on possible overinflation on the rear.

Outside of the rear tyre has lumps out of it..

Watching those sort of videos usually makes me feel nauseous and give up about 30 seconds in, but that was very smooth driving and good camera set up. Looks like you are having fun and enjoying upping your game to make the best of the car. Enjoy and stay safe, look forwards to the next installment.

But agreed on possible overinflation on the rear. Would tend to agree with this. The outer, broadest tread is heavily worn. The outside edge of the next, second tread section has been bevelled away. That cannot happen without weight.

Not sure if I’ve confused things with my tyre pics. Those are both passenger side tyres, most tracks obviously clockwise. Wear looks appropriate to me based on compound and physics. One positive for me is front and rear wear rates about the same. In my GT4s I’d do two sets of fronts to one set of rears due to understeer. Compounds vary across the tyre:

Here’s one of my 718 GT4 front passenger tyres:

Personally didn’t see much unexpected with the wear… given the various compounds and designated wear ratings across the surface. Just looked like Pete had used the tyre right down to its last possible run.. tread depth wise. How was the grip or were they also heat cycled out? Edited by TDT on Saturday 17th September 10:27

Edited by TDT on Saturday 17th September 10:27 Finished them off at Anglesey and they were certainly pretty greasy, probably cycled out after 5 days. Good fun though. Deep breath before Church and lift off oversteer on tap to get round the rocket left right. New boots for PCGB Oulton and hoping for decent weather. Might have a touch more camber too.

Certainly had your money's worth out of them badboy's Pete! Looked a handful in the damp at Anglesey Defo more camber needed!

Is the inside of the tyre softest and graduating to harder compounds on the outside? Your photo of the rear tyre looks like the both edges are less worn than the middle of the tyre. No traces of heat melt on the outside edge, and more tread on the inside edge compared to the middle of the tyre. That's what made me think that perhaps tyre pressure is too high but alignment fine. Either way it's an interesting contrast to your GT4 tyre!

Good read here MotoIQ- Not all cup 2 are the same On a tri-compounded tire, the outermost shoulder, only 2-3 fingers wide, is often made of an aggressive but very durable compound to handle the extreme abuse, high severity wear, heat, and sliding of a tire rolling over. Inboard of that is typically the most aggressive compound to maximize dry grip on the outer 1/3-1/2 of the tire. Meanwhile the inner part of the tire (it does not have to be the inner half and can vary from car to car) uses wet-oriented compounds. Transitions from one compound to another along the surface of the tire does not have to line up with the ribs. Often compounds will change within the same tread block. It all depends on the specific load acting on the tire for a specific car. Edited by TDT on Friday 23 September 14:42
