Looking at a mini-vaca outing this summer which would involve an 800 mile return road trip with two track days in the middle, in a .1 GT3. How do folks find track camber/toe settings fare for tires subjected to longer highway miles? Is it in the realm of possible to do this trip with a track alignment (-2.3F/-2.5R camber) and PSC2 tires and have the tires not cord inside shoulders? The easy answer I know is rent a U-Haul and tow the car but there’s some good backroads along the way that it would be part of the fun. Maybe try a compromise tweener track/street camber setting? Innovative ways to carry 4 track tires??

Don't over think your plans.

The alignment settings that you propose will present absolutely no problem for street / highway driving. No consequences what so ever.

The only precaution would be in heavy rain - definitely take it easy. Other than that - you are good to go.

Enjoy!!

I have 2.7F, 2.4R, and I did a trip from Seattle to Sonoma for a day, then to Thunderhill for 2 days, and drove home, no problem. The inside edges still had more tread than the outside shoulders of cup 2s at the end of it.

As mentioned, you’ll be using totally different parts of the tread on the road versus track with a track alignment. It’ll be fine…

Joining the chorus here. Stock alignment will work best for 2 track days plus 800 road miles with fun backroads. How old are your tires?

Really depends on how much u emphasize ur track experience. Running 2.6 F / 2.4 R with 20/80 ratio so min time on track but u can't compare the experience vs stock alignment. I really havent seen my road tires, mpsc2, get destroyed either. That said, gt2rs only has 5000 miles on it, and i have separate wheels for the track, BBS fi-r s / Nankang AR-1s.

Also, just a note, i really suggest trailering as I've seen too many track days ruined by flats, damage on the way to the track. If u can trailer, much preferred but I get it if no truck or access to solid trailer.

Hmm, my experience with stock alignment on past 996 and 997’s has been destroyed outside shoulders in 1-2 track days. This trip will be undertaken with fairly fresh (1-2 track days Cup2’s. I’m more concerned about cording the inside shoulders with the heavy track camber on 800 miles of hot summer roads. I will be doing an alignment in any event between now and the road/track trip in the summer so hence wondering if I should go full track settings or like 80/20 track/street compromise, say 1.8F/2.0R. But from comments here sounds like I should be ok with the former.

I have two year old Hankook RS4s with 10 track weekends with 1000 to and from miles awaiting new tires on Apr 18th. At least another 500 local miles. Will run the RS4s one last time Apr 15-16. 2013 BS camber is -2.5F/2.0R. You can definitely see the inside tread wear from the negative camber street miles more than the outer edges. The rears also show negative inside camber wear. IMO and experience you won't cord the inside in 800 miles, but you will see the wear. That said the -1.8 won't give you the best outside shoulder wear and you have more HP and weight. Again, IMO RS4s last much longer than PSC2s so you might see more wear. Hopefully someone with to and from miles on PSC2 will comment. The UHaul is the safer bet. With todays supply shortages I'd check replacement tire availability.

Stock alignment has worked fine for me for 7 years. 4 Smokies road trips with track days included and multiple times tracking 1 1/2 hours from home, there and back in the same day, with no issues. Tires held up fine (except for the right front tire which was destroyed at AMP, but that would have happened with any alignment).

If you are worried about the track alignment wrecking the tires why wouldn't you just stick with a stock alignment?

IMO the stock alignment in the 991.2 GT3RS paired with MSPC2 is pretty nailed in for both worlds.
Works super well on the road, and you have a decent tire wear in circuit.

Hi Skid, your alignment numbers totally fine for your plans, I would start out on a brand new set of Cups, fresh oil , and brake pads with plenty of meat on them , and you will be good to go to have fun there and to and from getting there !!

I wouldn't go with track settings. Stock is perfectly fine for your purposes. The 996 is different. My experience is that stock settings in the 996 indeed will wear out the shoulders in a few trackdays. So I had it aligned for track. Drove from Cleveland to Watkins Glen, about 300 miles, and corded the inside of my track tires by the time I arrived. Good thing my wife also drove our Suburban as I had a second set of tires..

One caveat on the MPSC2's. The outside shoulders will wear out faster on track use regardless of camber. One of our fave track rats, I believe it was Trakcar, went all the way to -3 camber, and he only succeeded in slowing the car down. It has to do with the dual compound feature of the tires. I've had better luck with Dunlops. With only 2 track days on your itinerary, though, you'll be fine with the MPSC2s

What are your toe settings? If you are at zero toe, or a touch of toe out (as is common for a track alignment) you will be fine with significant negative camber. Street levels of toe in with high negative camber is what will create quick wear on the inside of the tire.

Palting

If you are talking to me, the 996 was track aligned to zero toe to slightly out. IIRC, camber was about -2.5. front and -2.0 rear. Great on track with even wear. Corded the inside on a 300 mile highway drive on relatively new tires

Montaver

Was aimed at the OP originally. I drive to WGI and back (4 hours each way) with 3 days at the track, nearly 900 total miles with -3.0 front and slight toe out. I get no real inside tire wear to speak of. Are you sure there wasn't an alignment issue? I wouldn't do 20k a year on this setup but if were talking something like Cup2's which pure street driving they are dead after 10k anyway.
