I would definitely swap the S550 for an R34 if I wouldn't get bent over on the price 🤙
I might know a guy with one sitting in a container in central pa. I forget if he can open it this year or next.

Upgraded front brakes: Bullitt Brembo calipers, new rotors, stainless steels lines, and dust shields.

Also added some Steeda STH goodies:
  • poly vertical links (bought from a member here)
  • bushing support
  • alignment kit
Never understood what suspension compliance meant until actually having a suspension that feels compliant... all the "floaty-ness" in the rear is gone. Dips and bumps in the road no longer feel bouncy and exaggerated. Plus, the car stays tight and planted through the curves. Probably no need to do the IRS braces, but we'll see.

It drives incredibly well now, and the brakes look awesome!

Cleaned her up, courtesy of @DFB5.0 recommendations (and some that aren't).

Obligatory vertical links comparison

How did the SS brake line install go? I have a similar kit (950.61021) that I am planning to install. By looking at the SS lines, appears they are the same length. However, the factory brake lines are different lengths (driver vs passenger). Did you have any issues?

Finally got into the 11s at the track! She was consistent all night +/- .03.

You still don't understand what suspension compliance means.

You had suspension compliance (and too much of it), and you've removed some of it. Now your car feels tight and planted.....in comparison to before the Steeda parts.

Compliance is the "floatyness" and softness that is built into a Mustang's IRS.

No, that's just shit design and damping.
Compliance doesn't have to be deliberately designed in. Although on the S550 it is. That's precisely why it's there, to keep NVH low and stop customers from complaining. And damping is part of it too.

Wife did that 10yrs ago and ladder hit oil pan. Motor was toast. I feel your pain.
My first first thought was to straddle it. Looked short enough but it was too long. Safely swerved but not enough. Just barely caught it. I wasn’t the only one that hit it. Crapping thing is Apex has these wheels on back order until November. Taking it down to see if it can be used until new wheel comes in. Have alignment checked etc. think she is pulling to the left. Grrr

Sure hope you're not planning on using those on the road.
My 22’ GT is a dedicated 1/4 mile bracket car. It’s not driven on the street.

I didn’t have any issues installing the new lines: the Stoptech kit worked out perfect. I appreciate the guidance here on other threads to replace with SS at the same time.

I‘m not sure on the measurement of the new lines, but, you’re right, the factory lines are different lengths depending on side: 16 Inches and 15 3/4 inches.
