Nice! No buffeting, did you use the regular enclosure (not the skeleton)?

I have -2.7 front and -2.2 rear, zero toe. The wear seems even.

If I recall correctly, you wore out a set of PSC2s. How did they reach the end - cording (outside or inside), chunking or heat-cycling out?

Stock exhaust??

"Stock exhaust??"

Yes, everything stock on this video.

"Nice! No buffeting, did you use the regular enclosure (not the skeleton)?"

I'm not sure what you're asking about when comparing to the "skeleton?" I used a case that has the side input area open where I was able to attach a long mic extension. I then wrapped the mic end w/ tape to prevent wind noise and taped the mic under the engine compartment.

There's another thread discussing sound, but as you can probably hear, I'm not sure you can add to "perfection?":thumbup:

What's that thing looks like a hairy black vagina on top of your car? is that a decal?

Max. thanks for your video. You are new to 991 track driving right? I think your lines need work for a 911. Dont copy the front engined cars in front. Brake or accelerator - you only need to be part throttle when trailing or buttoning back if not comfortable with vMax. Come in wider on some of those corners do all your braking ins straight line - hard hard hard - then turn in when going slower than you would have thought and start winding the power on as you unwind the wheel exiting the corner, harder harder harder flat flat flat! Be good to get a 911 instructor to steer your car a few laps with you in passenger to understand what can be done. The 911 is oh so different to pilot fast than the M3 etc.

Ive just had my camber changed for track work. factory gear max out negative front camber -2.15" front and 1.54" rear. I have the geo sheet and can post, This guy sets up all my 911s for track and is very experienced.

Curious how you can get -2.7". you must have used spacers right or aftermarket adjustable lower coffin arms? I spoke at length with Chuck Moreland on this.

My thoughts are past -2.5 on this car too much for MPSC2 possibly. Need better R compound to take advantage of extreme cambers like Z214/221 Hankook or NY01 or DGZ03 (M2 compound) etc. That being said haven't punted mine around a track yet new engine just a few days ago and out of country. ...

Can you all post your geo please. Heres mine factory before and custom after. below that is factory specs from PAG given to my geo guy. Ill be experimenting it from here. Our tracks are shorter than yours but have way more elevation in general by observation...

Hi Macca,
The rears went to -2.5 no prob. The fronts required replacing factory shims with beefier ones and making a change to the lower control arm bushings to get to -3.1. With that setup, tires wore incredibly even but I am compromising braking a hair or too. If driven on road ply, it will wear the insides rather quickly.

No cording. Very even wear especially to the front. Didn't heat cycle out yet but was probably close.

I see, you used an external mic. Very nice.

I see what you are saying. Yes, I noticed that this car does not like trailbraking as much as M3. But it does not need it as much either.

I still see need for partial throttle - consider carousel (Turn 2) - a constant radius 180 turn. If I floor it in the middle of the carousel, I'll be going too fast for the diameter of the curve before I can track out. In shorter corners, it's possible to aggressively add throttle as soon as the nose points to apex.

My next track day is with Porsche Club, so I'll get some coaching and display of Porsche-specific lines.

The mechanic got 2.7 at the front without shims, just maxing out stock camber. He wanted to get -3, but decided that this is close enough because I'm planning to use street tires for now anyway.

Max, I'll be happy to show you what Macca means Thursday, don't waste time :-)

My thoughts exactly :thumbup:

How many track miles, days or sessions total?

Max. I dont think -2.7 is possible without changing something? At least Chick Moreland (Elephant racing) and my guy didnt think so - mine maxed out -2.15" but maybe that was the maximum while keeping the rest of teh settings in spec.

Can you post your geo? Id like to see the rear toe angles too?

Its really important with this car that the front toe and caster angles are not interfered with when changing the cambers.

OH MY GOOODNESS??? I just spit my drink out!:p

It's not a female part.

It's Kung FU Panda! You know, "There's NO secret ingredient."

Kung Fu Panda! Love it!

Yeah. Sorry about that. Not sure I would have guessed if you hadn't told me. It did look hairy tho so I was on the right track aye. Only suggestion to alleviate future comment would be move your gorpo forward next time LOL!
