Still waiting for my appointment.
I'm not much use for input but trying.
Your tires are wearing really well. The front pad wear reduction is a surprise..
I can see pressures at 31/32 - 32/34 being ideal for most tracks and conditions.
Camber -2.7 seems plenty. I think -3 is too much for the front and my tear Dunlops wear perfect with -2.7. I will try 2.5 all around with MPSC2. I figure now they last longer but heat cycle out.
I got rid of the Dunlops so I can try next setup with fresh MPSC2.
First annual service. Plus PDK oil and spark plug change. Also requesting info regarding mystery 13 page track setup modifications recommended by Porsche.
We'll see what what done in Germany and what not.
Fender liners for sure and raised the car for sure.
"But If the tire continues to grind in the rear wheel housing,
we can install Bump Stops according to a recent technical information, approved by Porsche in the rear shock absorbers."
TRAKCAR and others, attaching a slightly updated version of the doc posted earlier. This was updated by Porsche July 5th, although I don't see much difference to the original, maybe just the spacers for the rear springs?
When my car gets back to the States, I am going to get a baseline alignment done and see if I can track down the magic 13-page Porsche doc.
^^ Thanks guys.
Champion Porsche, both dealership and Motorsports department have had no information about this yet. Will find out what has and hasn't been done to my car and report.
running in open passing, advanced group
for those in bay area I'm running 2:00 at T Hill over the top configuration. this was 2nd day in the car and I dropped 5 seconds of my personal best in my previous gt3 991 so I was happy with the progress and this set up. no rubbing anywhere. I have not changed ride height. goal is to get to 1:58.
almost forgot. I was at Thunderhill the other day and it was hot- 95- 100 degrees. I was running MPSC that had one track day on them. I was running front hot pressure at 31, rear hot was 33 and I was happy with this set up. So far tires look even wear but I've only had two track days on car- keeping an eye on wear.
^^ See if you can get correct measured ride heights if at all possible.
My car has been unstable with front toe out, but that could be because of the bumpy track and -3F camber.
I agree with your camber settings -3F and -2.7R was too much.
I was at the Glen this past weekend with the RS and noticed that my left rear tire was cording again on the outside. This happened the the first left rear tire after 40 heat cycles and happened to this one at about the same point.
I was a bit surprised as a now have 2.7 degrees of camber in the rear whereas on the first set I only have 1.7 degrees of camber.
I looked carefully at the wheel housing and think that it is rubbing, though in truth, I never heard anything that sounded like rubbing, so I don't think it's a particularly hard rubbing.
I have attached pictures of the corded tire. Note it is corded so far outside that it's actually off the tread. I thought it could be from running the tire too hard before they are fully warmed up, but then put a piece of painter's blue tape where I thought it may be rubbing and ran one session. You can see that the tape has been blackened suggesting rubbing.
I called the dealer today and they are going to call me back about the technical bulletin. One question I have is should the work under this bulletin be done under warranty or is Porsche going to try to charge me for this because it's only a problem at the track? Anyone have this done yet? Under warranty or at the owner's expense? If at owner's expense, any one have a rough cost of the work?
Looks like another case of needed fender rolling (mine were rolled from the factory, April build). Haven't heard the suggestion about RWS, interesting.
