Holy Tramlining!

[Booboo]

With that much negative camber have you had issues with the inside shoulders of your tires wearing fast?

Perfectly even wear so far. Only about 700 miles on the PSS with the new alignment tho. Monitoring the tire wear every month, so far so good.

With the prior factory alignment, all my cup 2 tires were more worn on the outside after 4k miles(shouldve kept an eye on them oh well)...so I switched to max neg camber and keeping an eye on the tire wear...time will tell. Reduction of tramlining was a huge unexpected bonus of the alignment.

Replaced OEM size MPSs (f295/r305 35s) on 2018 GT350 with R replicas and OEM size R tire PS4Ss (f305/r315 30s) tramlining gone, smoother/more quiet ride, and turn in/grip improved significantly on the street.

Any issue with the fitment of the 315 in the back?

No issues and should have added on R spec replica wheels 11 f and 11.5 r

I'm currently running 325 on stock rear wheel with no problem (short notice available before trackday)

Another vote for PS4S. Did that on my 16 and it was instantly (mostly) eliminated. Some people will swear by the 2 point brace - but ask yourself, how is Ford going to put out a super stiff track car but allow the core structure of the car flex in a way that changes alignment when you're just going straight down the road. It's all tire width+compond+alignment+roads. That's why it feels different even if you go down the same roads. PS4S, my man.

Did the brace/alignment routine and thought it made it slightly better but I seriously believe its more the placebo effect - all phycological. It was so bad on alot of local roads that it was either consider selling the car or double down on new tires. Take your eye of the road for 2 seconds and you're partially in the next lane or fighting to keep it in the lane. Tiring driving it just for a cruise.

Went all in on wheels/tires - 20's with roughly R specs. 305s/315s MPS4s tires. HUGE different. Zero tramlining - 100% gone! Tires make the car feel more planted and a slightly less light on it's feet but much less nervous. For around town it's a dream. I should have done it on day one.

Yeah... especially from someone coming from Cup2s - a normal street tire weights somewhere around 3-4lbs more, each! So yes, I also noticed the planted feeling... some people like the twitchyness and rawness of the cars (especially the Rs) and I get that but it does get old after a while if you're street driving and honestly, didn't change my enjoyment of the car at all.

Not saying alignment can't help or contribute, but...tires. I changed to my current Continental ExtremeContact Sports and did absolutely nothing else, nothing...100% eliminated. Put my take-off tires on my sons completely awesome S197 car (full Steeda suspension, BMR k-member, the works)...all over the damn place.

I tried hard to get those Conti's, but nobody could find the rears. Not Tire Rack or any of the usual suspects. I needed tires, like yesterday, and found some P Zeros on sale for 15% off + free shipping. Love them so far, but haven't tracked them yet.

So, gotta admit that street driving this car can be tasking when it comes to rough or grooved roads. I'm currently running pilot ss 295/35/19 up front and 305 in the back. I have also installed the steeda k member brace. That did not seem to help at all. What kind of tried and true recommendations does anyone have to help minimize or even eliminate the tramlining.

I read a lot about tramlining before I bought my 2018 6 months ago. Now 6 months and 4500 miles later I had forgotten this was even an issue until I saw this post. Running pilot super sports.

Hmmm... Your previous owner probably got a neutral alignment?

I've got super sports in the front, with the factory alignment. I'm on my 3rd set of front tires, and all 3 have worn heavily on the inside. My car tramlines like it wants to murder me.

I've had mine for a while now. They're great. I thoroughly enjoy them and they're wearing great also. I forgot off the top of my head (I'll look tonight), but I think it's a 300+ tread wear tire. Maybe not as sticky as some others, but meets my needs drive great, and they've never unstuck for me, and they look phenominal. Would not break my heart to run them again. I refuse to run a Michelin, especially the 4S because IMHO, they run too big, and everyone and their brother has them, LOL I haven't checked in a while to see if they're hard to get. I'm going with the GoodYear SC3 (non R) next time just to mix it up a bit. That's a good looking tire too.

Post pics of your Pirelli's; would like to have a look.

which tire are you running and what size do you have on the front? Stock springs or lowered?

Stock GT350.
MP4S
325/30/19 rear
305/30/19 front

No rub on track (have 3 track days on them at thunderhill East).

I don't find the tramlining that bad. Currently have over 12,600 miles on my cup 2's.

Any idea as to what your alignment settings are? You seem to be the leader when it comes to cup 2 mileage.
