LSD and tires... like 40 TW tires
Iím looking to improve the acceleration/launch of the focus. I would like to be low 5 sec 0-60, and I know a lot of you have some data logging equipment. What have you guys done that has had the biggest impact on acceleration?
Iím assuming itís traction related like LSD and tires.

I was getting consistent 5.7 0-60 times with just traction and stability control turned off and very consistent 5.8's with Cobb's traction control and stability control turned off, which I was happy with since torquey FWD cars aren't the greatest from a dig. However, after installing my RMM and using Stratified's traction control with stability control off I've been hitting 5.5-5.6 seconds. This is according to the 0-60 setting on my accessport.

The TB Performance Torque Gusset paired with a stiffer RMM (in my case the mountune one) reduces torque steer and wheel hope to almost zero on stock power. I would say you gain a couple of tenths with just these two things. Much cheaper than an LSD, so I would start here then tires then LSD. What kind of power are you making? Stock power wont get you below 5.8s-5.9s (from 6.2s stock) even with a RMM, Torque Gusset, better tires, and LSD.
I wouldnt put too much emphasis on the 0-60 other than just for personal improvement. Car wasnt really designed with the 0-60 sprint as its number one priority. It's pretty easy to burn traction in first and second too, so i would put some extra emphasis putting your power down;stickiest/wides tires you can handle to help out, rear motor mount and maybe traction bar for bolt on mods.
This reading might give you some more insight (more so towards quarter mile but you can apply it to 0-60 to see if it helps)
Mod list here
LSD is a rather obvious yet expensive one that helps you put down the power even better as opposed to our stock "Electronic Diff" that utilizes braking and junk that slows you down and blows in the snow/bad weather.
Rear Motor Mount is a HUGE improvement that is a testimate to why it's arguably the most recommended mod on this forum along with intercoolers and stuff. Wheel hop killer for sure. Don't worry...the annoying vibrations go away after 100-200 miles when it breaks in
As also mentioned..Cobb/Stratified Traction Control which uses spark retardation to minimize spin instead of the stupid stock system which uses brakes (throws off weight distribution and obviously using brakes while accelerating hurts) just remember to turn off the stock system or the Cobb/Stratified system won't work...oh and play with the settings. A decked out car can use less slip and have better results.
Big one here...there are only 4 spots of the entire car that touch the road, two of which are the only spots that power is transferred to the road...cheaping out there is an obvious performance killer. Get good tires. It's expensive...and I need them too and I'm dreading that bill...but the difference is so worth it.
Additional stuff not usually mentioned:
Suspension bits. Coilovers go a long way with helping the car's weight distribution and weight transfer off the front tires that are providing power. Also, lower center of gravity helps more than you'd realize.
Power. Duh, right? Add power and it'll improve, but that's not really what you're asking and you knew that already.
Weight reduction. Lowering your weight by 100lbs is enough to see noticeable results on a drag strip...meaning it improves 0-60 too. Science and sh**.
Final one? Sure, you. You need to practice, practice, practice and get better at launching this car...it's already hard to launch...and each mod listed above changes it pretty noticeably. As you learn how to launch better and more smooth your times will improve. Do it on a prepped surface like at a drag strip and it'll only get better.
It's not a straight line car, and 0-60 isn't what it was made to do, but if you work on it and get all the necessary components you can improve it.

I've hit mid 5s to 60 stock by getting off the clutch just right at — IIRC — around 2k (maybe a little more, I don't remember exactly, but it was definitely under peak torque). From there, it's a matter of learning the traction limitations of the tires and holding it just at that threshold. While most of my cars have been low end torque producers, I'll admit that some of getting that traction balance right was down to luck for me and I couldn't do that consistently unless I practiced it frequently.
Sub-5 second 0-60? I'm not sure if that's possible without big turbo, LSD, traction bars, and slicks. A bigger turbo may be unnecessary, but I don't see it being done without slicks on a proper track. Even if you can launch perfectly, any imperfection in the road could cause wheel spin. Mid 5's seem to be the sweet spot, but you should compare how quick these cars are in a roll race which is where they shine. For example, I have a '94 Corvette. 300hp/350tq. My ST definitely makes more power than it and they're about the same weight, but the ST will never keep up with it from a dig and you'll never get the same kind of g-force feeling as you do with a RWD car.
Some good info here! Thanks to everyone who gave their valuable comments.
Currently I am 100% stock but I have been looking into a stage 2 package. I saw somewhere that a 300hp 400tq FoST only had like .2 improvement in 0-60 (it only had power mods) which is why I am wondering what non power mods will help get the power down better.
I understand that this car isnít made for hard launches and accel, but I am an engineer at Chrysler so all my coworkers have Challenger or Charger R/Ts and I want to be able to beat them flat out in a drag race. Whether or not itís possible with bolt ons and a tune, I want to try.

I doubt you could beat them from a dig, unless they aren't the best of drivers or you have slicks or something. I've roll raced a stock 2018 Charger R/T with the 8-speed auto, no idea what mode he was in, but I walked him from a 40 roll. Power to weight.
