I thought green cars where bad luck

....or is that boats?

I had an M3 GT in Green. Edition number 13. No bad luck there; maybe they cancelled each other out...

[Axel987]

insane, I want that sound. sent Erich a mail stating that

Sounds like a bloody ferrari!

I know - that sounds awesome!

[Axel987]

man I can't wait for those headers and exhaust.

Racing Erich also told me he could source the GT3 lower control arms for about 1000 euros a pair I think it was, supposed to be a really good price?

Yes that is a good price. Let me know how much for the headers and exhaust. I might be interested in the LCAs too but not just yet.

[Axel987]

you know it makes sense to just get the LCAs swapped too, no point in waiting

But what about Porsche Approved... will they still cover faults with a modified car?
What do these cars "need" to get the most out of them?

So far I know of:

Software remap (~350 PS?)
+ exhaust and intake (~370 PS?)
decent tyres (MPSS or MPSC2)
GT3 master brake cylinder
GT3 brake cooling deflectors
GT3 lower control arms
suspension alignment (-1.5 camber)

is there anything I'm missing?

GT3 throttlebody + 82 mm plenum + Longhorn headers

[PorscheGT4]

Not see any info to think the oem throttle body does not flow enough air.
The 82 mm unit can flow past 500bhp we are tuning for a real 350bhp !

All the car needs imo is rs29 pads SS tyres and max out oem camber for road use with top mount adjustment and fit front spacers. Plus unplug the exhaust valve.

Those are the most important things to do 1st imo.

After that, it's adjustable lca for more neg camber, rear solid monoball toe links and stiffer engine mounts with cup 2 tyres.

Then if you think the cars then handling ok then swap out headers, and put in light weight battery and seats.

To look for bhp 1st seems daft the car cannot be tracked oem set up so more power just seems pointless bar pub bragging rights.
GT3 MC does not fix any issues on brakes either just gives less pedal travel, that's masking a issue not fixing an issue !
If you don't have PCCB , then go for a 6 pot caliper conversion with 350mm 2 piece disks.

Last note, fitting lca to then only give you -1.5 is again pointless, I run -1.2 just adjusting top mounts, and on my other car with RSS LCA ( better than GT3 lca arms as you can set caster correctly, gt3 are fixed) I run -2 fast road and have shims to take it for -2.5 on track, but that does need a toe adjustment of about 3 turns to go from -2 to -2.5.

I do think people are not looking at the right things to change on these cars but hay ho each to their own and all that.

Demon,

agree with all you are saying.

I wouldn't do the GT3 MC without first trying rs29s and better fluid. Think that may be all that is needed. when discs are cracked/worned, get upgraded ones


then lca and toe links for full alignment potential... all set


out of the box, porsches are extremely well engineered with regards to heat management but to be on the safe side, i would even install the 3rd radiator which PDK cars come with.

for a bit of noise maybe the carnewal solution which should still keep things within noise limits.

But HP? I have many other lightening stuff i would do before i even go near HP

this is such a well-balanced car, why change any of it unnecessarily?

there is only 1 other angle which is to strip out ac, interior, change seats for that all out track weapon

What toe setting do you recommend with the top mounts moved to give -1.2? I have SS, but new rears and well worn fronts. I think I'll change out the fronts as they feel loose. What does the front spacer do handling?

[PorscheGT4]

very slight toe in or dead ahead, I had slight toe in on my Spyder as it helps to get heat into them a bit, I do means a nats cocks though, I was having issues with heat over winter, might go back to straight now for summer.

front spacers help turn in. all Porsche ever do these days is add front track 50MM for the RS as it happens.

Adding 14mm front track really is very noticeable with the camber at -1.2 a perfect road only set up imo.
done the chalk test on my car and I use all the tyres and save the outers.

But I have Cups 2's going on this week ;-) cannot wait to see what that brings on the Spyder, also R rear ARB goes on this week also it's 1mm thicker.

[J-P]

I find the braking performance of the R to be fine. It's the sponginess of the brake pedal that I don't like, which the GT3 MC fixes. The car is fine on track, yes more adjustment would improve things further and I'd do that at some point too but there's no escaping the flat spot, I don't want a remap for more power although that would be a nice benefit, I want it to get rid of the daft flat spot. Once those things are done, I think you have a very nice road car which you can use on track. If you then want to make it more of a track weapon, then yes RSS LCA, monoball toe links, MPSC2 etc is almost certainly the way to go. When the Potenzas wear out, MPSC2 is what they'll be replaced with, I think they'll make a massive difference.

[John McM]

Thanks. I've just booked in for an alignment and will get those changed. No adjustments to the rear?

I've been spoiled with semi track tyres on my 964 so am learning to drive on SS without the extreme corner grip. Cups would be the go, but I'll wait until my SS are worn out first, which may not be long with the camber on the car!

er , no it does NOT fix it, it just makes the pedal move less !

Car is pants on track ,you just kill tyres In a few laps esp "Potenzas" , ok I guess if you are going roads speeds ;-)

Flat spot is a none issue also, I have to go out and try and work out how to trigger it, and ffs you have to be in 4th at 28 MPh that's the only time you see it.

NO one should be in 4th at 28Mph, it's the biggest none issue of all.

So, sorry to bring up these points , But I doubt you have driven a car with a GT3 MC in it, I also doubt you have even been on track in it ! And the flat spot comment is a joke.

That may sound a bit confrontational, but your lack of any idea about this car is frustrating, and you wanted to fit 10k worth of shocks to it !

I keep SS on my R 100% of the time, with the adjustment and camber there is a lot of corner grip with SS.

No it's just typical of your general demeanour on here followed by the "I'm completely innocent, woe is me" bullst that subsequently comes from you. Glad to see you back to your usual form. My car is fine on track, for me. If it doesn't work for you, that's fine. I'm no driving God but I know what I like from a car and what I don't like. I don't like the pedal feel, I've been told that GT3 MC improves the pedal feel and I'm happy to try that and see if it works. The fact that the flat spot doesn't annoy you is great for you, I'm pleased. It annoys me to know it's there. and yes you're completely correct, my car has never been on track. And seeking opinion on how to improve my car and voice things I've been thinking of is what a car forum is for. Your masquerading as some sort of expert and irrational hatred of the GT3 is one of the most irritating things on here. What happened to giving up PH?

Please PM the email in my direction also please.

Would be interested to try them and look after the seats.

[Axel987]

Jesus christ MrDemon you are well rude, a bit uncalled for. Seem to remember some other guys on here told me you were slow as a snail on track, still you are dishing out track-advice like you are Niki fecking Lauda

I love my CR, but they CAN be improved upon, even if you think they are the best thing since Sliced bread with ham and way superior to any GT3 etc...
