My Velocity Blue LMP750

[2021LMP750]

Good morning everyone I’m new to the forum and wanted to introduce my 2021 Mustang GT Premium with a LMP750 kit installed on it. It is a dealer installed accessory kit from Long McArthur Performance in Kansas.

My car is in Velocity Blue. Has a stage 2 Roush Supercharger Kit, 6 spd manual, custom leather seats, and a links well 12.5” tablet screen installed. We have affectionately named the car Sonic (fast and blue) and we are planning to get a custom plate that says BluBlur

My last mustang was an 07 GT and this is a major step up in power and handling. I love this car so far.

I’m excited to join the forum and look forward to learning more about these cars from you all.

I am also new to the forum. I own a 2018 Mustang GT (17017 miles) with a dealer installed Roush Phase I supercharger kit wih the TVS R2650 blower unit.
Orange Fury Metallic. Performance Pack 1, MagnaRide, Active Exhaust.
See posted photos.

UPDATED 8-1-2025: My Mustang GT now has rolled over to 20100 miles. Drivn daily in the summer to and from work (20 miles on e way) when the weather forecast is quiet (no storms). I am amazed how good the with the latest tune I uploaded from Roush in April 2025.

I also changed the throttle body that came with the original 2018 Roush kit (2017 Shelby GT350 analog with digital conversion module) with the Roush suggested 2019 Mustang Bullitt digital throttle body. The vehicle is pleasant to drive as an everyday commuter and gets it on when you press the GO pedal! Just stay clear of rain storms.

I thought they generally swapped the wheels out on these?

They sale the package in stages
Interior, exterior, engine, and suspension/wheels.

When they made my car only the engine and interior stages were purchased.

Welcome to both of you. Great looking cars. You're going to need wheels and tires.

Welcome to the forum. Beware, there a number of DBs lurking around here too. And some people act like they know what they are talking about, but dont. Anyway, weed through it and you will figure out who knows theor shit. Good luck

I wanted some color contrast on the hood so I purchased the Roush Gloss Black Hood Heat Extractors and installed them this week. I love the color contrast. Adds so much more attitude to the front of the car.

Welcome to the forum!

Since you’re new to the S550 and it’s forced induction - and even if a prior Mustang owner, it’s very very easy to get the ass to come around and kiss ya….

And one other thing - if you’re in a climate zone where temps drop due to seasonal changes (winter), do not attempt to drive on “summer only” tires below 45*, unless you have very good prior experience doing so…. A S550, with a supercharger, new to the platform, and hockey pucks in the winter don’t mix well, even if there’s no snow or ice on the roads.

Do your research on tires and as stated above - there’s a great deal of tech and good folks on this site. Ask questions, plenty will offer help.

Good luck with the S550, it’s quite nice!

Took some time and spray waxed the car today. Naturally I had to take some new photos. I can’t believe the way this color shines when it is cleaned up and waxed.

+1 on not driving on summer cities below 45
I had a gt500 with 650 hp the car is basically not driveable when it cold.theres basically no traction as said the tires are like hockey bucks. If you don't hit heavy throttle you'll get used to it so you can drive it i did but be really easy on the throttle

My 2018 Mustang GT Premium Performance Package 1 (Roush 2650 supercharger) even with new Pirelli P Zero Nero all season tires is not safe to drive below 45 degrees, in rainy, snowy, or icy conditions. If you live up north like me, leave the car in the garage over late fall, early spring until nice weather returns.

The summer tires that came with the car at 8700 miles were worthless for street use unless heated up.

We took the car out for a 6 hour round trip cruise this week for my wife’s birthday. Naturally we had to take come pics.
I also just ordered the ford racing bright pedal set and the light weight steeda clutch assist spring with gift cards from my birthday gifts this year. Looking forward to the additions to the car.
