Really like that spec so much so mine is nearly the same. Just threw in PTS and PCCB's.

[Phooey]

Respectable time for the GT4 @ Magny-Cours!

I've been a few times and find the car in fronts instructor makes the car stick to his lines and will not let you past, as it's by consent, YOU CANNOT use your own judgement ! In normal cars the tyres go off in 3 laps as they don't lower the PSI, so a trip to the water part to cool them downs seems order of the day.

GT4 should have cup 2's on so that's not an issue though. I would rather take the GT4 out on the road than do PEC, bar the low friction bit.
the rest is easy once you have done the kick plate and water slide , it's doable at max speed and a non event.

key was to go off line pick up loads of st on your tyres then do the low friction with tyres covered in crap, then that was better.

weird ,when I did the gt3 the guy just said..'just overtake the others '

+1

When I went PEC had no issue with overtaking. I was in a GTS and both me and the GT3 on the track where overtaking everything. It was such a small track it was unavoidable. My hypothesis is if you can drive and don't act like a tt or complete bully the front car will alway just wave you through, or on the straights your given a green light by the instructor to just overtaken when you want, just don't take the piss. just like a track day.

Does anyone know if you will be able to fit 6 point harnesses at a later date if you don't have CS? Looks like they are anchored to the bulk head behind the driver / passenger and not wrapped round the cage bar?

I am thinking of deleting the clubsport option and passenger harness for a few reasons.

1. My max budget was £75k before with tracker etc and have gone a tad over. Wasn't an issue until we just purchased a new house which is also a little over budget (always the way) so going to be stretched for a bit. Cutting the options down a little will keep the little lady happy ;-) So I am looking to make some spec cut backs to use some of the car fund to put towards stamp duty. LWB, leather and CTS are a must for me so I am already up to about £72k just with those.

2. I def wont be driving round with 6 points fitted as they are a PIA on the road and I find them quite dangerous actually in the way the restrict you (seeing out of junctions etc). Ill track it 2 or 3 times a year max.

3. I am going for yellow stitching inside and would Ideally like yellow harnesses. Being a bit OCD having red harnesses would make my st itch so I know I would just re-sell the red and try and get some aftermarket ones in yellow.

I am speccing for me as see this as a keeper until if / when they bring out a GT4 RS so no too worried about the whole it adds to re-sale value debate. I expect it will make it easier to shift but don't think its a big a deal as the GT3 clubsport.

Anyone confirm the anchorage position?

[Fish]

Pretty certain they anchor to the bulkhead. You can't retro fit CS but I assuem the harness points are welded to the chassis. Maybe not bother with CS and get an aftermarket harness bar??

[P155flaps]

Cheers Fish - Yes from videos on-line you are right determined its bulkhead. Having mulled it over all weekend decided to sell some bits to make up the short fall (some crypto currency). So despite the reservations about the red belts thought for the sake of £2650 and some thin air that may go down in value as well as up id bite the bullet and shift that for a small profit and put it into a bit of metal and fire extinguisher - proper first world issue!

Nagging in the back of my mind all weekend was that I would regret not having the half cage case just for the experience factor (plus safety).

[Fish]

Your fire extinguisher is red as well! Maybe have red stitching?

I can conform this, impossible to tell the diff now between the 991GT3 RS and 997RS 4.0......GT4 feels more 991GT3 like, bobs and weaves more..

You have a PM David......tks

Drove the GT4 at PEC today. Everything said about the car is true. Gearing didn't feel as long as I expected but short circuit meant I rarely moved out of second until the newer section. Air con didn't work and car was exceedingly hot so don't wear layers. Incredible car which really shines on the technical outer track on the new section I felt.

Spotted RHD yellow gt4 sunday whilst at silverstone. What did you think of pccb ?

Good to hear more positive posts about the driving experience! The car you were in is the yellow one they had on show at the preview evening, they are using that for PEC and it has air con delete hence why it was so hot

PCCB were excellent. I wasn't pushing hard on the handling circuit but on the new section where I was in 2, 3 and 4 and carrying much more speed, the brakes were working harder. Much harder. Did about 4 emergency stops and lane changes and then continued round the handling - no fade or juddering or even a sound from them. Pretty sure that there would be some objecting noises from the brakes if I was doing that in my R (running steels). I have spec'd them on my GT4 anyway and I think it's the right call.

I edited my original post to say that I never really moved out of second as the gearing was tall enough not to require it.

My driving consultant was very good but didn't know much about the car having only driven it for the first time that day. He seemed to think that the aircon wasn't working versus being deleted - we ended up on the kick plate to cool the car down a bit. If anyone specs their car without, they're braver and more committed than me.

One thing that was good about the car was that the assistive systems were not as intrusive - I recall driving other cars on their track and even with ESC and everything off, it never really gave you full manual control.

I despise the electric hand brake in the GT4 - would have been more fun with a manual hand brake as well. Really easy to balance the car on the throttle though.

[anonymous-user]

A couple of camera phone snaps as well.

Great Tks for the write up and pics pccb may be the way to go then by the sounds of it though regular steels Wont be lacking . So will you be tracking the car much? Just thinking of the whole issue with pccb on track (though I personally think its totally blown out of all proportion )

I've opted for them and I'm going to have to agree with you when you say it's been blow out of proportion. I think if you a tracking the car 2 / 3 times a year and follow the correct cool down procedures and change the pads to RSC1s when on the track you'll be fine.

I've got a couple of friends with the latest Turbo S who have tracked quite a few times this year and the gen3 rotors according to them have come on so much. They are even using standard pads and they are showing very little wear

Did you have the opportunity to switch all the assistance systems off at any point? If so, how did the car behave?

Good too hear about the PCCB - I've opted for them as well

I will track the car probably 2-3 times a year. I've read all the debate but then I've also spoken to people who regularly track with PCCB and they have not had any real problems - one of my mates put his car in the kitty litter and a stone that got caught did some damage to the surface. He replaced and swapped out to steels and then put the PCCBs back on when he sold the car. They're both heavy track users - 5-6 track days a year - Bedford, Silverstone and Spa so I'm inclined to trust their experience.

The first thing I did was turn everything off but the instructor asked me to leave it on for the first couple of laps - likely to assess my temperament and what I was like as a driver. After a lap, he just turned it off for me and let me get on with it.

The handling and control the car affords. Fantastic. At the kick plate, we were avoiding the plate and going in at higher speed and flicking the back out and balancing on the throttle and figuring out where the assistive systems would kick in. It's very neutral as you'd expect but it feels very alive in your hands. I felt like I should have taken the R up for a back to back comparison for feel but there's time for that when it arrives but the steering had good feedback - it's certainly far better than any other 981 series car I've driven including the GTS but not having driven any recently, that may not be fair comment and I'm relying on memory.

It was very easy to drift the car and balance it on the throttle on the low friction surface, flicking it round the tight corners leading up to the circle and then out again really shows just how good the chassis is. I felt like the session was very short but when I looked at the time, I'd been out for ages. I felt like I hardly scratched the surface of the car's ability. The wait till December has been made more torturous.

Regarding PCCB, one thing you should try on the back track is an assessment of braking distance - there are white lines across the 'runway'. My instructor asked me to hit maximum speed from the start line at the opposite end and aim to emergency stop the car on to the opposite line based on when I felt the stop would bring the front wheels to a stop on the line. It took me three attempts - I kept stopping too short because the brakes were so good.

"on the low friction surface, flicking it round the tight corners leading up to the circle and then out again really shows just how good the chassis is."

not sure how that shows up how good a chassis is , on a low friction surface, you can do what you did in a car 20 years old and it feels great.

How are people deciding the 981 chassis is better stiffer than the 987.2 cars ?

it's NOT possible !!!
