Spyder owner bent his tread blocks back on his P zero at Anglesey !!!
Hi David - that was down to tyre pressure spiking and has recovered after the drive home. Last set of front zeros lasted roughly five or six track days and 5k miles - I'm not getting understeer despite less tyre width, less camber and less sticky rubber than the GT4. Still managing to keep up though
- I am however trail braking and loving the the movement in the back end!!
See you met Scott the other day. Top bloke. Proper petrol head and a very handy driver! Trying to arrange a trackday for when he comes down next to see you

Now that sounds like an excellent plan.... 2 Eleven v GT4 v Spyder comparison is the full fat pistonhead experienceSee you met Scott the other day. Top bloke. Proper petrol head and a very handy driver! Trying to arrange a trackday for when he comes down next to see you
I thought about a 2 Eleven but it's most sensible ( ! ) as a trailered car and I 've wondered quite how good an Exile could be ?
I spoke with par yesterday about trying their GT4 Clubsport for a day --- the cost came up to the best part of £5k (???????) with an in-car instructor for the first part of the day at least to assess the car/driver combination.
Parr are currently taking the worst case wear / reliability / hours and combined with he fact that it's still not homologated for GT4--- I'm really pleased that I didn't buy one because it wasn't rod legal. I'd hope for a modern spin on the 964RS N-GT that I used to own.
Looking at the situation now, maybe it should have been ... if legislation would have permitted the delivery fit front cage (welded in).
As an aside David --- I'm very interested in you thoughts --- would an extra small amount of negative camber make a noticeable difference to my speed ? Or might transfer wear for the outside shoulder to the inside ?
I asked Strasse on Tuesday when they were looking over my car and they suggested leaving it alone --- and driving what I have.
There is something of a leveller driving a standard car. There will always be faster cars ...

It,s a fine line Chris as you get the most from your car as it is and post the fastest times.
one must say if you are happy with all that why change anything.
if you want to go just a bit faster then a bit of extra camber will allow more apex speed which also mean less brakes needed into the corner, which means you are faster out the corner and then faster up the straight. It has a knock on effect of being faster every where not just corner speed.
I cannot see Hugh inner wear at -2.3 unless you do a load of motorway, the issue like the GT3 is rear inner wear due to the size of it.

Hello, that was me in the BMW following you. I thought we had a good run. Nice clean lines on a largely empty track in the afternoon. Car isn't fully tracked up, full interior still but decent suspension and brakes with cup tyres make a world of difference helping to rotate the car. Great driving
Have a vid of that run, so will put it online shortly.
]
Was a great few laps, what I did notice was I looked far to much in my mirrors and then that caused me to miss a few apex's it really unsettle me lol I think I def need to do more track time to not be as nervous. Have a vid of that run, so will put it online shortly.
]
That's only my 5th in 3 years., I need to get Craner sorted also I have a mental block and keep my speed down though there to about 90 where Chris was 106 !
The pressure was too much hence I pulled over in the end :-) my mate drives a BMW v8 and they are a dead heat in a drag race right the way upto the BMW limiter vs the GT4 a real 2 cars in one, nice daily and then when on it a load of fun, bar the mpg lol I had one for 2 months and I just got fed up with the small tank and high petrol costs as I do a load of miles.
The GT4 is , would you believe it worse again on petrol which makes my mate laugh now :-(
I was shocked you were always in my mirrors so nicely driven ;-)

No it isn't, the GT4 is noticeably faster in a straight line! The M3 is now sold, but I had a E92 competition pack car as a daily alongside the GT4. The GT4 was waaaaaaay faster in the bends, and far more fun too - The M3 was a comfy barge in comparison, albeit a very capable one.Edited by Porsche911R on Friday 10th June 09:20

Whats everyone running tyre pressure wise on track?
I was running 2.2 bar front and 2.3 rear hot.Talking of tyre pressures, can anyone suggest how to turn off the tpm warnings? the car keeps on telling me my rear tyres are underfilled by 0.3 whether on track or off when i repumped them up and it's damnably annoying....

I thought one needed to set it to circular path...which works for the first session or two...but after that it seems to go all haywire and unhappy. Need to read the user manual Talking of tyre pressures, can anyone suggest how to turn off the tpm warnings? the car keeps on telling me my rear tyres are underfilled by 0.3 whether on track or off when i repumped them up and it's damnably annoying....

you must have a faster GT4 than mine, or a broken M3 :-) as I dragged upto 155mph vs my mates DCT and it's a dead heat.the DCT gains him 3/10th of a seconds every gear change over my manual change of course.
The m3 feels far slower as you are in comfort, but they are the same speed.
BHP always wins it has 415 over ours at 385bhp and with the added GT4 wing drag.
So sorry to say you are way off :-(
to back up the drag race I DID FOR REAL, goto fast laps, 0-60 in both is 4.3,(we beat that in the m3 on Vbox) 0-150 in one is 23.9 and the other 22.9, just about a dead heat !!!
Yes it's faster in the bends over a car on road tyres !
we also did some Vbox sessions on my mates M3 and beat the booked times by a fair margin.
Fun is a tricky one as in M mode the M3 is a hoot and you can be a hoonigan in one and drift it every where.
I had one 2 months and also felt the weight on B roads so moved it on, and I did not gel with it at all, but it was not slow.

I have no issue with TPM it's great, every time you put the key in it again asks circuler R mode and new pressure, I say yes and it's been great on trackTalking of tyre pressures, can anyone suggest how to turn off the tpm warnings? the car keeps on telling me my rear tyres are underfilled by 0.3 whether on track or off when i repumped them up and it's damnably annoying....
if it does get it's nickers in a twist then yes it's hard to then reset it, but at Donny it ran like a dream.

depends on geo, ARB and driver style ;-), so the same old annoying question where one figure does not fit all but one which gets asked time and time again.any where from 29psi to 35 psi is the answer.
I ran 32/35psi fully hot and that was perfect for my car as it stands pyro proven with no cool down lap ;-)
I was shocked it went upto 35psi at the back. but as I said at Angelsey I tried 29 psi like some use and it went greesy after 3 laps !
Cups are very stable I find once set also, Dunlops never seem stable, so gain depends on tyre fitted.

Its not slow at all, but the GT4 is blooming quick in the right hands.

For info, my supersports would drop by 4 psi between track sessions (20 minutes after cooling down), so I always did a couple of warm up laps at the start of each session to get them back to pressure. They then felt very stable for the rest of the short (15 min) session. Never got a feeling that they were going off (but that might be down to me not pushing them very hard).ravon said:
Steve, we are in the garage under the Control Tower at the beginning of the pit lane .
Nice to see you chaps yesterday. Im sorry that i didnt get to spend more time with you. Had some problems with the brake bias mechanism on the Cup car and were trying to sort it out over the lunch break. Nice to see the GT4's going well. Some very poor driving standards on the day unfortunately. Very annoyingly dragged my GTS against a Golf R DSG in Scotland the other week. Rolling start. Those things are RAPID! Almost nothing in it up to a fairly decent speed. Only starting to pull away at the top end. Very annoying to keep seeing a £30k hot hatch up your chuff when you're absolutely flat chat! The DSG has a lot to do with it though.
