Fixing the notorious "Tramlining" issues with running wide front tires on your S550 with the Steeda 2 Point G Trac Brace!

[kai20035]

Maybe it did something for you guys running 285s and under...but with the factory 305 cup2‘s on the front of my R, I wasted the money on this bar.

I'm not sure what else could be the issue as with me I first checked my PSI's on each tire, didn't need an alignment so ran into this G Trac brace on Steeda's Youtube video addressing this problem and wanted to try it. The complete video is in the link below. I had my son drive my car today and even he noticed the major change!

Yes, cause my Bridgestone Blizzaks WS80's I use for my winters feels like there's 1000 pieces of bubble gum stuck on my tires! I go through a full tank of gas in 3-4 days...

lol...what is this “winter” you speak of

cmon down to San Diego this summer, and I will throw the cup2’s on for you to take out on a Friday night...you will burn an entire tank before midnight, I can guarantee it

I have 275 squared on mine but have never had a tramlining issue. Is 275 not wide enough to cause that or is it just me?

You're running the this Steeda Extreme K brace? I didn't take that route because I don't track my car so it wasn't required.

My car drives like a ho cart. It moves left and right as fast as I can move my steering wheel and the front and rear track and slide perfectly. I installed the Steeda extreme brace up front as well as BMR Front Radius Bushings, and BMR rear Cradle lock out II kit, and some other Braces. I also had new two price Forged wheels made and running 285/35/19 front and 325/30/19 rear. It does ride stiffer, but not much noise increase. It is day and night difference. Really, drives like a ho cart hard and fast.

Don't think 275 would cause tramlining as this problem usually starts with 285+ tires...

I'm in Ontario Canada and in a COVID lock down but if I'm going to SF I'm not going back to Ottawa! 🥸

I also fitted the Steeda 2 point brace yesterday

I upgraded the the hardware a little as my subframe had very few burrs and the Steeda spacers were a little loose (I know others have had to grind them down a little bit as they were to tight) :

Very easy to fit, I was back at home by 9:00am after doing the the work myself on a borrowed lift :

I’m not sure the rear IRS stuff will be as quick or easy ... lol

Nice European tail lights and yes I didn't realize we had those burrs sitting in the sub frame but my guys just used a long skinny screw driver to pop them out! I did my rear IRS components when I got my 16 GT within the first year. I floored it one day and almost ended up on the curb! After that ordeal I ended up putting in the Steeda sub frame brace, Steeda IRS & sub frame bushings, BMR Street differential bushings and put away the race ones cause it causes some NVH & J&M vertical links. Now I can launch from a dig or a roll and not have to worry about ending up on Youtube's next Mustang compilation of "Mustang's that love 2 dance!"

I test drove a 2020 with the PP2 that tramlined pretty bad, turned me off a bit.
Understanding it's a different car but I when I run Eagle F1 Supercar 3R's on my Mini the car tramlines all over the place, straight as an arrow with the factory Pirelli's, if that's of any value.
BTW: Haven't grabbed a pony yet cause covid prices went crazy but want to follow this thread.
A nearby dealer has a 21 with the performance package, is that the equivalent of the older PP1?

I don't know about the brace but I agree with those here about tires. My HPP with handing pack uses 265 40 19s all around. The stock Pirelli PZero Corsa 4s tramlined. When they wore out and I fitted Michelin PS4S the tramlining disappeared.
