GT4 was traded for the .2 GT3, cannot help but think that the new .2 GT3 engine in a GT4 platform would be an ideal combination, although have not tracked the new GT3 yet, so far I prefer the size and driving dynamics of the GT4.

but the new 4.0 is out of this world! worth the price of admission for that alone

Congrats mate. In that green colour as well? Would be beautiful. GT3 has always been my goal car, hopefully one day.

A 500hp 4L in a GT4 would be epic. Deman have done a GT4 Stroker kit which takes it to a 4L and approx. 500hp.

Looking forward to seeing it out at the Burrows Day. I should be there on the March 8th one.

Charlie,

I am a huge fan of the monoball bits, as they provide you the feel with almost no concessions around NVH. I have used them on all of my Porsches in the past, and if you search for every last tenth then they certainly help. Confidence and feel is where the lap time comes from.

I haven't fitted the front bar (Warwick has) but the rear made a huge difference for me. So my front is new and unused but Warwick likes them both apparently. The GT4 rolls way too much (soft springs) and the bars help that certainly. Again the faster you go the more you notice this, so its all relative. The faster you go the more these parts make a difference. Plus with the monoball bits if you do one part you might as well do them all, That's why I did them all.

DSC Controller is a must in my opinion, and it's a 10 min swap and will cause you no issue when 3rd gear fails, or you just swap it back out, very easy to do.

I upgraded the rotors and pads purely for longevity as Porsche rotors wear very fast. The girodiscs last a long time and have much better cooling (72 vanes). braking performance didn't really change much, as the softer Porsche rotor do bite hard, but save the expensive Porsche rotors for the street. The DS11'1 pads feel better than the stock pads also, more consistent. With the upgraded rotors brake temps are much reduced after each session.

My plenum, Headers and Evolve Techniq tune however blew me away. My power graphs speak for themselves...Couldn't recommend them highly enough. The standard car feels like the handbrake is on until 5000rpm, where as now it pulls hard and from low down. 430hp easily...

The extra aero bits certainly have slowed me down the straight by a few km/h but you can feel it in the turns. My speed through turn 1 is a prime example.

But like anything Charlie you can throw lots of parts at a car, but you need to push to extract the benefit of these bits, its a very slippery slope mate.

Cool let me know

Snowman.

Yeah I have them. I'm 10km/hr slower down the main straight at PI but 10km/hr faster through T1.

At Bathurst I was also about 10km/hr slower down Conrod but I was 1s faster across the top. The net result at both tracks has been pretty much identical lap times though with and without the aero. But I think the aero looks cool and you definitely feel like the car behaves better even if it isn't any faster. So I'm leaving all of mine on..

Snowman.

Also - Mark and I both prefer the Trofeo's at 32 hot.

Charliekay

Understand mate. I have done some good times at SMSP and Wakefield on not so perfect laps, so I think if I can get a few more parts to get the car to behave better then I can do some great times. I am aiming for a 1.05.xx @ Wakefield and done a 1.07.10 with traffic and the car as is.

Can you PM the price for the DSC controller and Aero parts and I will do some research on the other bits.

Thanks.

If the car behaves better then it will probably help improve overall lap times for me because confidence plays a big part, especially at places like Bathurst where it is my first time racing it and don't really have deep enough pockets to risk damaging it.

mungee

No more than 30 for me as the car gets very greasy for me anything above that. I usually try to run 29 hot. But be careful as some gauges vary as I have discovered. And 29 on mine might be 30 on your etc etc. At the last supersprint Hamilton's, mine and another gauge all showed 3 differing results, 1/2 -1 pound between them all.

GAZZ

I ran the GT4 at Barbagello for the first time in the GT4. Wow, now I see what everyone is saying about the tall gears. It was ridiculous. 2nd / 3rd / 4th, WTF...

Also ran the Trofeo R's, miles ahead of Pilot Sxxx and Maxx. Fantastic road rubber, but A050 they are not... Hit 1.46 lateral G's. yeehaaaa.

Was out at Wakefield yesterday for PCNSW Supersprint and went home with a 1.05.33 which I am exteremly happy with. It came from the 2nd session of the day, but unfortunately the day was cut short due to an incident on the track and the track needing repairs and deemed unsafe. I think there is a 1.04 in it so will try get it in August when we are back there.

Here is a video of the lap.

Warwick Morris

Congrats and awesome lap mate. You are certainly doing the GT4s justice. I saw a photo of the car from the "incident"; no chance they're going to buff that out.

Charliekay

Thanks mate. Was expecting to see you there.

No chance they are going to buff it out. Unfortunate for the owner, apparently it is only 2 weeks old.

O5C4R

must of been enormous to damage the wakefield park track enough to close it down considering how it looks normally ha ha - driver ok?

Charliekay

Driver was fine, car not so much.

He went straight on at the fish-hook and into the tire wall. Because of the damage caused to the tire wall it wasn't structurally sound and was unsafe to continue with the day incase someone came off again in the same spot.

There were a few people taking photos of the car afterwards so some will probably find their way online.
