GT 350 Rims and Tire on my GT Performance Pack

[Wana go Bro]

I just put a set of GT 350 rims with Pilot Sport Tire on my Eibach SportsLine lowered GT PP. My ar seems to be all over the road when I drive it. it feels like it is following the groves in the road. I have gotten the car aligned but it still feels like it wants to follow the parts of the road that are uneven.

That’s normal. 295’s on the front will do that

There must be a way to fix that. I wonder if I need a Bigger sway bar?

There are things you can do to help, but nothing is going to “fix” it. You’re dealing with a tire that’s much larger than the stock size. Talk to some of the gt350 and pp2 guys with the sport cup tires. They’ll tell ya

That's also one of the things I've read people who daily their gt350 don't like. It's hard to defy the physics of a wide, good gripping tire.

You can try running a little less aggressive tire. My Bridgestone Potenza S-04's don't tramline hardly at all running 305's up front.

I have the same issue. Like others have said, to be expected because of the 295’s up front. I did have the Ford dealer do a custom alignment so that it matches both the GT350 and the PP1 specs at the same time, which helps but won’t cure it.

My suggestion would be to run a less aggressive tire as stated previously. That’ll provide the biggest improvement. People have also reported improvement with the use of a k member brace

Just a product of wide tires. My previous car, 2019 Toyota 86, had 215s. That car never tramlined. My Mustang with the 255s does it but not all that bad. The wider you go the worse it feels. Big rigs cause ruts in the road. A narrow tire will ride inside the rut. A wider tire kind of bounces off the sides of the ruts. Nature of the beast

So I was able to adjust the amount just of tramline by increasing the tire pressure on all 4 corners. Much more bearable.

My advise is to dial in a small amount of front toe-in. it will help significantly.

Increasing tire pressure a little isn't a terrible idea.

Make sure the tires aren't too old/bald. Old bald wide tires tramline terribly compared to new wide tires.
