Lower Control Arm Installation
After installing the 94 spindles (Cobra front
brakes) on my 86 Mustang, I found that I lost lots of camber. There
was one side I couldn't get negative even with CC plates. I wasn't
in favor of slotting the struts, so I went looking for another way.
I chose longer lower control arms.
The 87-88 T-bird has arms about .75 longer, while the SN95 arms are about 1.5 longer, per side. My feeling was that 1.5" was too much, so I chose the T-bird arms. |

These are the 86 arms vs the 87 T-bird arms |
|
While doing the change out, I installed urethane bushings and some of the Steeda X2 ball joints. | |
The install went as usual. Rip out the brakes, struts and springs. Remove the old arm, install the new. Note that with the longer arm I had to relocate the mounting hole for the sway bar end link. I just measured and redrilled. | |
With the X2 ball joints raising the height of the spindle, to keep the same ride height I installed a provided spacer on top of the spring. However, with the longer arms, I still lost a bit of height. I'll do some coil overs later to get it back. | |
After bolting everything together I realized
that the threads going into the outer tie rod were not engaging too
much. I looked into several solutions and decided to purchase a kit
instead of piecing things together. I purchased a Steeda bump steer
kit to get a longer assembly. Hopefully I'll see some benefits from
the bump steer part also.
Another item, most of the bumpsteer kits require you drill the steering arm on the spindle for a 5/8 bolt. I didn't want to do that so the Steeda kit is made with a tapered stud like the original. Below you can see a stock piece and the Steeda parts. |

I do believe this should give me the camber I wanted. The tires were leaned in so far I had to stand them back up with the CC plates so I can get it to the shop. I'll post the results after I get an alignment. | |

"87 and 88 Turbo coupe are the same length as 94 and newer arms but the ball joint is fox style, The 99 and newer arms have a reconfigured back side (thinner) to allow more tire clearance and if rack limits are removed, a 10 % tighter turning radius and redesigned bushings" |

This kit enables owners of 1994-04 Mustangs to upgrade to 2003 Cobra Mustang
control arms. The kit features (2) front lower control arm assemblies with 50%
stiffer rear bushings and low friction ball joints. This control arm has a
redesigned stamping to improve the turning circle approximately 10% on 1994-98
Mustangs.
