Hey all, just mounted my HP wheels with summers and I’m selling my stock wheels, no plans to drive this once the winter comes around since we have another car. Fronts - 255/40/19 Yokohama Advan Sport AS+ with about 70% life left Rears - 275/40/19 Yokohama Advan Sport AS+ Little bit of curb...

Hey everyone! I got my trans and diff fluid flushed the other day, had to take it to a local performance shop because I didn’t have access to a lift this time. I took two quarts for the diff (capacity is 2) and four quarts for the transmission (capacity is 3.3) and they needed to grab a third...

Hey everyone, got a quick question for you all. When did you change your brake fluid? My Mach 1 is a 2021 but only had about 10k miles on it, is it worth it to change the brake fluid yet? Or should I wait until the recommended mileage interval?

Hey everyone! Going to be changing out the trans fluid soon, swapping the stock stuff with some Redline D4 and I figured I’d to the diff while I’m at it. What have you all used for it? I’m seeing Redline 75W-85 GL5, not sure if that needs friction modifier added to it.

Hey everyone! Got the HP goodies in and I installed them the other day during some downtime, everything was pretty simple even the spoiler. Now just waiting until Wednesday to get my roof wrapped in satin black, and it should be complete until the summer wheels/tires go on!

Hey everyone, picked up a non handling package Mach 1 that I'm in the process of adding handling package accessories to. I ordered the Mach 1 HP spoiler and I found that it only comes in gloss black, not the satin black/dark gray that the HP cars come with. My question is, has anyone wrapped a...

Hey everyone! Just picked up a manual Mach 1 and I have a set of TuxMats I just put in. So far it doesn't feel like it interferes with the clutch, especially with some wearing in over time, but I wanted to know if anyone else had experience using them in their manual S550s. Has anyone had any...

Just got her in yesterday, a 2021 race red Mach 1 that I had the pleasure of picking up and driving for the first time in the snow lol. Got a few things planned, including the handling package goodies, and I wanted to get the roof wrapped to accentuate the black around the car. Wanted some...

Hey everyone, bought a non HP Mach 1 and I already have a few HP cosmetic goodies on the way. The only part I didn’t order was the front lip extension, I love the look but the decreased ground clearance makes me nervous. Has anyone installed it? What are your experiences? My car will be a year...

Hey everyone, got a 2021 Mach 1 without handling package on the way so I’m making plans for a good summer tire/wheel set to pass the time. Currently looking at the SVE MHP1 wheels, since I want the handling package styling while also getting a lighter wheel, specifically at the 10” with 35mm...

Hey everyone! Just wanted to get some input on how much fluid changes typically run on the Mach 1. In the past, I've changed oil, trans fluid, and diff fluid on my own, but I'm at the point where I'd most likely take it to the dealership. How much have you all been paying for oil, trans...

Hi everyone, just wanted to make my first post here to pass some time by while I wait for my new (to me) Mach 1 to come in! It's a 2021 race red with less than 10k miles, currently on a carrier from Texas to Michigan. It's a non HP, so I've already been planning the things I want to do (HP...
