Fantastic Joe !!! Keep it coming. Please post your alignment numbers. What about caster?

Also shows how good the Spyder is - a car costing twice as much is only 5 sec faster.
Drove mine to Vegas & back last weekend. Easily the best car I've ever owned! Crazy fast! Not the same rush as a Turbo S or GT2, but it's nearly as fast and handles much better. Revs so fast I agree - a manual would be tough! Even managed close to 21mpg with my wife in the car. Not so good when solo, even though I kept it under 150 most of the time.

The funny thing is, after other guys sat in/drove the car, they all talked about selling their car to move to a 991 GT3. Whereas, I still have no desire to sell the spyder and still look forward to driving it at a future track day.
Thanks! Much more to learn to and improve on still!

BTW, the LWB seats are great for track use. I had no problems with support even with the 3 point belts. I want to run the harness and hans mainly for saftey purpose.
The AiM system does NOT integrate with gopro. Only their smartycam system. You have to process the video and sync with data exported from AiM using software like trackvision, dashware, race render, etc.
No problems with cooling. 200F or less all day long for water temps.

I would complain to Porsche about this and demand a refund for the cost of the worthless Track Precision App that is clearly mis-advertised if it is performing how you describe.
The track precision app -
I'm sorry to say this, but it is a totally worthless POS. Don't get it. You won't use it. Just get a Solo DL and call it a day. You can't export video. It drops out, it's buggy, and you have to push start on your phone to activate every time. To add insult to injury, the only video that it put together for me was OUT OF SYNC.
Garbage.

Maybe they'll improve it with software updates in the future. I'll take a video of the video off of my phone and you can see how pathetic the sync was. Even more pathetic that I can't export the video and have to use another camera to record off the phone.....

Good stuff! My first track day with the GT3 will be in a month, so time to start getting the car ready.
Your G-meter is showing peaks of around 1.5 G, which is rather high. How does that compare with the G-meter built into the car?
The lap time delta compared to the Cayman is about what I expected for a 2-min track, and pretty huge. Translates to a delta of about 25 s at the 'ring. And of course the delta will be bigger when you have more seat time in the car. Did you run with PSM on?
Did you change the oil before tracking it?
Looking at the owner's manual and race track manual, Porsche says that the factory alignment (-1.5 cambers) is good for both the road and track, and seems to discourage changing it. And a pro racer I spoke with who has a 991 GT3 also suggested leaving the alignment at the factory settings for the track. But your cambers of about -2.5 sound more reasonable to me, based on my experience with the 997 and Cayman. Like you, I'm willing to give up a bit of grip to even out the tire wear and get more life out of them, given how expensive they are. Has anyone run the factory cambers on track? Anyone gotten tire temps? Maybe try -2.0 as a compromise?
PFC 11 pads sound good, I'm going to order them.
The hassle with the CL wheels sucks. For my first track event, wife and I will be sharing the car and logging ~10 hours of track time over 2 days, so I think we'll need to L/R flip the tires after the first day. Not looking forward to that. Anyone have any thoughts on whether these tires will last 10 track hours (~800 track miles) plus hundreds of miles driving on the road?
BTW, still waiting to hear from my dealer on what Porsche says about the passenger seat.

So, is it pretty easy/straightforward to get the timing right from the AIM system and the go pros with the right software? I am not too tech savvy and wonder if it is a lengthy and complicated process. Thanks again!
