Hey Keith88 did you found the problem on your truck?

Yes they do, They fight A lot of wind around 125 but get close to 135 before I backed out of it can’t remember exactly as it was a few years ago and it slowed down like I dropped a anchor; I Was chasing 3 R8‘s in Mexico.

Ive become accustomed to the truck shedding speed like crazy without heavy braking at high speed... I was driving my buddy's 991.2 c4s the other day and had a "oh shit I need more brakes than im used to" moment

So leaving work I Decided to give it the beans. At 100mph truck start wobbling to the point I had to let off. Totally coming from front end. Thought maybe it was the road. Got on highway and same thing. Never done this before. 37 truck. Like unsafe to drive at 100mph unstable swaying/wobbling.

Any ideas. Tire pressure is the same it’s always been.

Were you able to identify the cause?? My 2023 R does the exact same thing.
