Last week, the Hot Rod Garage crew set out to figure out which handling package — Ford’s K-spring or P-spring — works best on their last-generation 2005 Ford Mustang. Last week, the crew installed the K-spring, and this week goes on to undo the work to install and compare it with the P-spring.
The spring is part of the Ford Racing’s Assembled Handling Pack (part #M-FR3A-MGTA), which contains the following components all designed to work together as one package:
- Assembled Front Struts M-18000-A with rear shocks, Lowering Springs M-5300-P, Upgraded Strut Mount M-18183-C and Jounce Stops M-5570-A
- Sway Bar Kit M-5490-A
- Adjustable Rear Panhard Bar M-4264-A
- Includes all factory required one-time use fasteners
All in, the handling pack costs roughly $1,500 which seems to be quite the value considering all of the parts. And those hoping to fit their 2009-2014 Mustangs with the parts should know that the mods apply to all S197 (aka fifth-generation) Mustangs from the 2005 thru the 2014 model years.
So, is the Stang better with the P-spring or K-Spring, and can the handling setup really shave time off the autocross course? Find out in the video (the build & test lasts until the 11:06 mark and the rest is Q&A).
