Ford Mustang Track Pack Dissected by Part Number…

Update 2 (23May13): Although not entirely specific to the track pack option, I thought these two items are still insightful.

  • The 5.0L GT power plant utilizes 34lb/hr, 6-hole fuel injectors (M-9539-LU34A) that sport USCAR (EV6) electrical connections
  • 2010-2012 Mustang GT500 rear splash guards (AR3Z-16A550-AA/AB), which have a slimmer design, became standard on 2013 Mustang GTs

Update 1 (25Mar13): The rear calipers (BR33 2B118) are the same as non-Brembo/Track Pack options’ and V6 model front calipers. The track pack wheels (BR331007BB) have the following measurements inscribed on their rear spokes (19×9.0Jx42). Additionally, they are also marked as made in “China”.

The Dirty Hippo Racing team have wanted to write this post for awhile. For months, we have been recording part numbers during our various installs. We have previously highlighted the Ford Mustang’s Track Pack option in one of our most highly viewed blog posts of 2012, “How to Build A 2013 Mustang GT Race Car Without the Fluff“. We will now expound on that topic for 2013 and (soon to be) 2014 Ford Mustang GT owners.

By now, most of us have determined that the Ford Mustang’s Track Pack (option code “55R”) comes with the GT’s 5.0L V-8, six-speed MT-82 (Chinese) transmission, optional 19″x9″ wheels, Boss 302 radiator, Boss 302 engine cooler, and the eye catching Brembo four-piston, front calipers. Honestly, that was about all I knew when I purchased mine. It wasn’t until the Dirty Hippo Racing crew began to tear into its chassis and suspension components that we began to discover what other components were added (and more importantly, not “publicly” disclosed by Ford). Cue evil laughter…

  • Front struts (Designated by Track Pack sticker): BR33-18045-EE. The stock 11-13 GT and Boss302 share the same front, upper strut mounts. The ubiquitous Ford Racing GT500-style mount (P/N M-18183-C) are 2005 to 2010-era and required when installing Ford Racing’s performance strut/shock handling kits. Therefore, ensure that you are purchasing ’11-’13 front struts (for example, KONI’s 8741-1549Sport) when using the stock strut mounts.
  • Front Sway Bar (34.6mm): BR33-5482-BE E29EA. Same diameter as stock GT (Source: http://www.brembo50.com/Default.aspx?pageId=1130035). OEM sway bar began to laterally shift from its stock bushing mounts under load; therefore, I recommend an installing lateral locks if keeping the OEM unit to prevent such an occurrence.
  • Front Sway Bar End Links: BR33-5K483.
  • Front Springs: SEE BR33-5310-EA E29EJ (seen on bottom left compared to the Boss 302 OEM springs).2013_GT_vs_Boss302_Springs
    Dropping the front still kept caster, camber, and toe within GT (factory) specifications. We also compared the resulting output to the Boss 302 specifications, which appeared good as well.Camber_Caster_Settings_Post_Boss302_Springs
  • GT500 Front Brake Cover (designated with a Track Pack sticker). Appears identical in form and function to BRBZ-2K004, which I have on hand for comparison. Designed to safeguard steering components from increased heat radiating from the Brembo’s heavier workload.
  • Front Lower Control Arm Brace: BR33-5A095. Similar in form and function to Ford Racing’s M-5025-A.
  • Rear shocks: BR33-18080-EC. OEM shocks did not have adequate dampening for normal driving conditions (in conjunction with the stiff Hellwig rear sway bar system.)
  • Rear Sway Bar Bushings: 4A037 R648B.
  • Rear Sway Bar End Links: CR33-5C488-AF.
  • Rear Springs: SGR BR33-5560-GB E29EJ. Replaced with rear Boss302 springs (P/N SVR CR33-5560-VB E29EJ) to cure the rear suspension’s “pogo” sensation noted with the Brembo-specific spring package. This rear spring swap, in conjunction with the KONI yellow dampers, cured this annoying handling sensation.
  • Ford Racing GT500 Style Rear Lower Control Arm Pair: M-5538-A.GT500_LCA
  • 8.8 Rear Axle Assembly (P/N: S219-D) with Torsen Differential and 3.73 gears. Note: Synthetic lube only. Do not use Ford Additive Friction Modifier with a Torsen differential. Reference servicing documentation.
  • Ford Racing 8.8 Axle Cover (finned): M-4033-K. Includes integrated, threaded drain and fill plugs.Ford_Racing_Finned_Axle_Cover
  • Stamped Steel Panhard Bar Body Brace: 174D12A.
  • Heavy-duty, shot-filled panhard bar. Replaced with Ford Racing M-4264-A, which is used on NASA AI and AIX class S197 Mustangs and a service replacement part for the FR500S and Boss302R1 race cars. Manufactured from 1.125″ OD x.095 wall thickness 4130 chrome moly. An adjustable panhard bar was desired even prior to lowering as axle was NOT centered from factory.
  • The Brembo50.com website reports that the Ford Mustang’s with optional Brembo package (55D) came with option specific rotors, and pads. Luckily for us, Ford rolls up the Brembo option into their Track Pack option (code 55R). By the way, excellent web site!

As you can see, Ford included a lot more into the Track/Brembo Pack than we originally thought. I hope that you spread the word specifically about this post as I have encountered a lot of inaccurate information on the web. Thank you for reading and continue checking out DirtyHippoRacing.com!

    • I would need the remaining part number or year/make/model to ensure you are provided with a correct recommendation. With regards to leaf springs, a lot of older production cars share leaf springs with F-series pick up trucks. Companies such as Energy Suspension and Prothane tend to make hi-perf leaf spring insulators for these applications. I would google the part number and see what other truck applications its used in.

  4. Very good write ups. I have 2013 track pack, question regarding suspension. I would like a slightly more planted rear end. I’m not racing, but have taken it out for a few track days. A friend offered me a set of stock boss springs. Is that a step in the right direction? The front feels good but I’d like to put the power down earlier.

    The car is bone stock so far, but getting the itch to improve it.

    I sold my 04 z06 for this mustang and do miss the handling.

    • The track pack had different rear springs AND rear shocks. My car drove better (less oscillation) when I replaced rear springs; however, it launched harder (and become much stiffer) when I upgraded the panhard bar, corresponding rear chassis brace, and rear sway bar. You’ll have to decide whether or not you desire a comfortable ride or a wild stallion. Overall the Koni Yellows couldn’t hold up to my aggressive setup, so I wouldn’t recommend it for a daily driver.
