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
