On Cup 2 R also!!

has to be now to get the time below 7.12 by a bigger margin than the 991.2 car, shame really all this R spec stuff as you cannot see how far the cars moved on by. I guess they wanted a sub 7 minute ring lap and should really be faster than the out going RS on those tyres, as it should be quicker on the straights with less drag than the old RS and be as fast in the bends with the new aero.

Is it purely ironic that the host of the pictures is Carscoops, something this GT3 has in abundance!

They have nowhere to go on the GT3 bar trying to get less drag and better aero.

The lighter new wheels will help and it has 10 pot brakes :-), I know we say Porsche brakes are great, but I would like more from my GT3 in the brake dept.
the 991.2 had a very old brake design and still not powerfull enough imo. Hauling the car down from 140mph needs more braking performance.

Cup R and 10 pots should I hope rip your face off. I keep meaning to change the oem pads in mine but at >£1k it will have to wait.

They should try making them much much lighter.... yep - new wheel design will help... seem to have taken pointers from BBS FI-R - but they could really try to go further... a return to fewer systems and less weight.

I've driven Ginetta G55 race cars on a couple of sessions over the last 2 weeks..... lightness is the key to everything.
Lower kerb weight yields smaller lighter braking system, better braking, turning and acceleration, better body control, better ride and handling, better efficiency and overall more fun and cheaper to run.

you should have a little drive on my Spyder, you don't need anything more on the road, and the change of direction and brakes are on another level.

My FI-R’s arrive next week Been a loooooonnnnnnng wait.

very very nice, are you fitting the cup 2.5's ie the connect tyre ?

[Porsche911R]

Cheib said:

Oh I’m all over that. I’ll be Mr “all the gear and no idea” at the next track day.

yes but you will be the one with the last laugh having tyres which look as new on the way home.
over having to buy a set every 1/2 day like some do as spending money = fun some how and "tyres are cheap"

win win the 2.5 cup 2 connect imo. faster, safer and more track days from a set.

[Porsche911R]

Cheib said:

Ah....I’ll get on the phone in the morning then!

I certainly wouldn’t be ordering wheels from BBS again in a hurry....st show. Shame as the product is so good.

You did have a custom colour as standard they are black or silver.
Plus they are going though changes.

I'm not sure that I understand the benefit of this technology? I start off at 1.8bar left hand and 1.85 bar right hand (Clockwise circuit). After 2 laps the tyres are up. I'll do another 2 laps and come in and check them. They almost never need bleeding off. Once they are up, I leave them like that all day. I never do more than 5 lap sessions. After my last session, I leave them for an hour while i mince about packing things up etc. Then I pump them up to road pressure and go home. Tyre management is not a difficult or dark science

What would I do differently using this technology?

The benefit of this technology is not for you though :-), it's quite clear it's for the novice who don't change temps (ie the ones asking on forums every day what temps to set and why are their tyres nackered after 1/2 a day) and stay out 20 laps at a time. this tech will get people to set a correct pressure and when the tyres do over heart it will tell them to come in, or do a cool down lap or 2.

the advantage for every one is setting different left and right PSI's over guessing. Unlike BMW which give you quite a lot of Data in the computer. Porsche data is just PSI. So it's one less thing to worry about and also the cup2 connect is said to be abetter tyre than the normal cup.

26 psi is a bit low imo to go out on, It's put too much movement though the tyre and NOT recommend by Michelin.
I guess OK if not pushing, hence why I drop them a bit on arrival do 2 siteing laps just to see if the tracks the same layout, or if a big curbs been put in any where etc etc, then do a bleed down, then do 3 faster laps and a 2nd bleed down.

I don't want to damage the framework of the tire running too low too early as you cannot see the damage.

Michelin are being quite strict atm about how to use their tyres as people are miss using them or using them out of their guidelines.

' Dear Mr Menegaux

My name is Mr Demon from Pistonheads, you've probably heard of me I'm the chap who's constantly posting about my driving prowess and how quick I am in my 991.2 GT3 (perfection specification I would add) although I've never taken the car on track.

I must draw your attention to your incorrect inflation pressure information:

INFLATION PRESSURE ADVICES

On the track for majority of car (*)
Cold tires
• Inflate the MICHELIN Pilot Sport Cup2 with a pressure between 1.7 bar (24 psi) and 1.8 bar (26 psi) front & rear
• Never allow the pressure to be below 1.5 bar (22 psi)

24 psi is way too low imo to go out on, and as for never allowing the pressure to be below 22 psi, this is ridiculous, It's put too much movement though the tyre and NOT recommend by myself as Pistonheads resident driving guru. PLEASE TAKE NOTE OF THIS FFS!!!!!!!!!!!!!!!

I guess OK if not pushing, hence why I drop them a bit on arrival do 2 siteing laps just to see if the tracks the same layout, or if a big curbs been put in any where etc etc, then do a bleed down, then do 3 faster laps and a 2nd bleed down.

I don't want to damage the framework of the tire running too low too early as you cannot see the damage.

If you require my services for tyre testing at Ladoux, I have a 30 minute slot at 2.30-3.00pm on a Friday when I'm not spending all my waking hours on Pistonheads.

Best wishes

Mr Demon'

All my info is factual and correct, you can take the piss, but it's there to help novices, I pointed out to the OP on the "
981 GT4 Unusual Left Front Tyre Wear" why his tyre had done the above, YOU have NOT offered any advice to the OP or any one else.

here is the letter back from Mr Menegaux :-) if you care one jot about the tyres on your cars.


"" Regarding your query for the track usage of MICHELIN Pilot Sport Cup 2, please find our recommendations below.

MICHELIN Pilot Sport Cup 2 is a track tire, which meets the legal requirements for use on the public highway. It has been specifically optimized for use on a dry track.
On a wet track or road, where there is a risk of aquaplaning, adapt your driving style by reducing your speed and leaving the safety and driver assistance systems connected.
For track and road handling reasons, the fitting of a set of 4 MICHELIN Pilot Sport Cup 2 is strongly advised.

Before Fast Circuit Use always:
Verify the condition of your tyres, checking for wear & damage
Build up to the temperature of the tyres gradually by a few more moderate paced laps

Pressure:

Hot tyres
The optimal operating pressure of the MICHELIN Pilot Sport Cup2 must be between 2.2
bar (32 psi) and 2.3 bar (34 psi) Front & Rear
Never allow the tires to run below 2.0 bar (29 psi) HOT

To warm up the tyres and adjust the inflation pressure:

1. Cold tires: inflate the MICHELIN Pilot Sport Cup 2 with the recommended pressure

2. Bring your tyres up to temperature with a run building up the pace with a run of 3 to 6
laps (dependent upon the length of the circuit). The first few laps should be more
moderate and not close to the limits of the tyre/car (respecting the limits of the
driver/car/brakes/tyres will prepare for a better track day) Bring the tyres up to
temperatures progressively especially if the tyres are new

3. Return to the paddock, and immediately check the hot pressures of the tyres

4. Re-adjust to the recommended pressure

5. Repeat a second run of 3 to 6 laps at a more normal pace getting closer to the potential

6. Re-adjust to the recommended pressure for a 2nd time

7. You can then use this pressure for the rest of your Track day

After running on the circuit and before returning to the road:

Always check the condition of your tyres to ensure they are safe and comply with relevant local traffic laws
Allow the tyres to cool ideally before making appropriate pressure adjustments
Re-adjust your cold tyre pressures in accordance with the pressure recommended by the car manufacturer
If they have been disconnected/switch off, re-instate all safety systems, driver aids and tyre pressure monitoring





There is also another Tech doc about swapping over the Cup2's side to side which talks about groove direction and how the tyres has been designed for the left of the car, and hence why you can swap tyres on the front to even out tyre wear.

I would say most will order a touring this time round, which will knock the current prices a bit on those.

Link removed !

Steel rear brakes pccb fronts :-)

[Porsche911R]

new seat design, phew...

looks like the bottom of the folding and a new top. I hope it now has tilt and heating with height adjust the best of both may be.

A fixed carbon bucket will be fine for me thank you. No heating, leather or stitching options thank you very much.

Merc and BMW always use Carbon Reacro Pole's. Porsche seem to want to redesign the seat every model.

My DTM is very special and uses the correct seats and has 3 way passives as standard. BMW know how to throw the book at the top models.

That looks nice. The 996 GT3CS was Porsche's version of a propper Club sport driving tool. Built to drive to the race track and race it. Lightweight buckets etc. It wasn't as stripped out as the 964/993 RS Clubsports before but Hardcore drivers forgave it that for the motorsport hardware that the car had. Then the 6RS came along and went a little way towards the old C/S models but had scope to lose a lot more weight. Since then to be honest, the RS has become a bit of a nonsense, morphing into a car designed to be all things to all drivers. Surely thats what the vanilla GT3 should be. The RS should be something far more focussed than the car that it's become. I think that Porsche have really lost their way with the RS models. Someone may argue that perhaps there should be a super lightweight RS version - but that is exactly what the RS should be anyway. It wont be a popular veiw on this forum.

I agree the RS models are a bit naff for a RS model and today weigh more than the standard model !, but still class leading in the field today still lapping faster than the new 765LT even !

Porsche you have to buy a stock model, drive it to A-workx in Germany and spend £30k on it. And in an ideal world £50k and the modern buyers not going to do that. The RS to date has gone the LGBGT+ route, not sure what that means for the owners ;-)

The thing with any GT3 is the DNA is there to make it want you want it to be if you wish. Manthey are killing it and of course 51% Porsche owned so many routes to make a GT3 the car you WANT to own.

I think it’s a real shame they’ve lost the genuine lightweight ethos.....”add lightness”....I know Weissach pack etc is supposed to do that but it pays lip service to the principal. Imagine if they made a modern day Carrera Clubsport or 964 RS...the latter barely had any more power than a Carrera it was all about weight reduction, stiffening the shell and chassis improvement.

I think at the price these are at they cannot do it, all they can do is redesign the aero.

when you buy a Pista and Ferrari knock 80kg out of a car you pay £280k for it a GT3 is £111k

My GT3 cocks a wheel on a bump so you can spin it, the chassis not moving. The engine's done, the 991.3 was aback step imo due to regs, the itb are hype imho and not true ITB's !

shame no WP for a normal winged GT3 which is already the lighest .1 GT3 they make anyway.

I worked out with really not much hassle you can drop 250lbs from a manual GT3 (inc the cage removal) and that's with out fitting RS carbon bonnet and plastic rear and side glass.

you could see a 1340 KG 991.2 manual GT3 imo.

why has it got a manual gearbox and paddle shifters ?

Same weight but only 10bhp more ?

some odd stuff there.

not odd, it's a mule to get click bait and the hype up and it's worked.

Fair point....lightness costs. But imagine a factory car minus 150 kg....they could charge an awful lot for that car.

Be nice and £280k :-(
