Castle Combe today!

[tscaptain]

Don't know whether I should be pleased or not with this photo! Had geometry set up at Centergravity the day before! Great day at CC, very quiet, only about 16ish cars, open pit lane for most of the day. The PDK was excellent and "involving" in manual! Note the Gen 1 Carrera S wheels (2nd hand for track day use only!)

So many responses....

"Does your 997 feel light at the front"

"Do numberplates give cars a character?"

....and so on[]

Looks great by the way [8D]

 

[tscaptain]

Actually Mark, after Chris had changed the geometry (what it came with from the factory was all over the place!) the front end doesn't feel light at all. It felt really planted all the way round, even with 3 wheels on the ground!
Think we did number plates on another thread!!
Great fun day had by all[]

I think its a great picture []

Certainly shows that you were trying!!! []

Great weather today but coombe was a bit to far after the meeting in Derby with the local regions...

Thanks Gary. Certainly a good work out for the car. The photographer chappie was pretty chuffed with himself too. []

That's a terrific shot, one for the garage wall! Good to see the car (and box) working well.
What made you think the factory settings were out - did Chris at CG find them outside the factory tolerances or did he just tailor them to your preferences?

Peter

 

[tscaptain]

Well, to be precise Peter it went something like this....
On rears different camber each side, both outside factory tolerance (too much negative) Left rear toe in too much and outside tolerance.
Fronts - left camber outside tolerance and different from right. Both front toe out giving total of -0.13 (tolerance is 0 to +0.05!!!) Apart from that it was beautifully set up! Not bad for a 7 month old car with 3k on the clock![] I suppose the OPC would say it has "settled on it's springs"!
Chris set less -ve camber on rears to make it less understeery (and not wear out the rears so quickly!) and equalised the front cambers on the -ve end of tolerance to give a bit more bite. Also slightly toe in overall for stability over the bumpy stuff. At least I think that all that he told me. 4 hours with Chris and you get a bombardment of info![] He aimed for a "neutral" set up for fast road/occasional track
I thought it handled ok (ish) before but is lovely now. After a couple of sessions on track today I felt really confident in the car. Money really well spent and a masterclass in geometry to boot.

Hmm, perhaps I should book a CentreGravity session.

Great photo TS, I am still to do my first car track day. How did the brakes hold up? Any fade?

PS: The rear spoiler is up, so you must be doing at least 70! []

"Alan desparate to save tyre wear on at least one corner."
"Alan wished he put two sacks of spuds in the front storage space."

Great to see a Gen.2 doing track days already. Give that PDK a good testing for the rest of us!

 

[tscaptain]

Hi Marc,
Brakes were fine, some interesting smells from various parts of the car after each session (and I don't mean from the inside!) I think I was getting an average around 80, topping out at 135 just before you brake for Quarry. Had to let quite a lot of air out of the rears in particular to keep the pressures around 40 (That's what Chris told me to do!). It was my first time at CG and well worth it!

Hi Chris,
[][][]

PDK in Auto and Sport+ is unbelievably quick and always in the right gear. Guys on the pitlane wall commented on fast the change was as I went from 3rd to 4th past them! It does rev the nuts off though. I used the day to experiment really, trying all the diffferent options.

I was with Chris at Center Gravity all yesterday - and I can now declare that, after much modification and experimentation, I have found Porsche 911 nirvana!! (I will write up a big report later)

Alan - great pic, glad you had fun!!

I was going to go and watch, but thought it was the 21st.
Now been informed there was a printing error in PP []

 

[tscaptain]

Yes Rich. Those attending got about 10 days notice of the change of date! The next date is correct, I hope, on the 16th April - I'll be back for more fun![8D]

Would agree a great photo, but I am puzzled that geometry settings could be outside factory tollerances in six months of use, or maybe
there is insufficient time given to weight the seating, allow for empty fuel tank etc. to adjust correctly on the tight production line.
Porsche insist that all used cars for sale have their geometry checked and corrected. Surely this could be extended to new cars in the
pre-delivery check without hurting the pocket of the OPC.

You and me both, John! But I have the print outs to prove it! One can only assume that they weren't in tolerance in the first place. Certainly is both more stable at speed and better balanced than before. I think the greatest deviation from the factory tolerance was on the rear cambers - which certainly could be due to settling down on the springs/compression after 3K driving?

 

[Jane Smart]

Alan, that is a really great picture and as someone pointed out, one to be enlarged for the garage wall I think []

My car had settled over time thus altering the settings, you will read how much Alex's had settled in just a short time aswell and thats after a new suspension setup.
You would hope they are checked at PDI though wouldn't you []
As ever standard setting are to cover the worldwide supply and many of us have had a slight tweak for our own personal requirements.

[tscaptain]

It begs the question as to how many are driving around with settings way outside of factory tolerances? I really wouldn't have expected to have mine checked after 3K and then find they were so far out and unequal side to side to boot. Glad I did though![]
