I had the FRPP Springs and sway bars installed a couple of years ago. I also upgraded to 18" FRPP Black Bullits with Kumho 255/45/18 tires. VERY firm ride! I kept the OEM struts/shocks and have finally decided to install the Eibach Pro struts/shocks (to be delivered today and installed this weekend hopefully). The FRPP Springs and sway bars are manufactured by Eibach for Ford (same as the Pro System). The OEM Struts/Shocks are not designed to work with a lowered suspension, thus a harsher ride. Several things to remember:
- If you change the sway bars to the FRPP or Eibach ones, set the bar to the middle setting on the end of the sway bar. There are three holes to adjust your amount of anti-sway. I have found the middle setting just right, but may change it after I install the Eibach Strut/shocks.
- Even going from 17" to 18" wheels will give a firmer ride. Going to 20" wheels and tires will give an even firmer ride. Remember you do not have as much sidewall to absorb road shock, etc....
- Every system is matched to a certain point, so you may want to stay with the same brand for all the parts. Yes you can combine (for example) Eibach springs, Tokico struts/shocks & Saleen sway bars. But you may not get the best ride, stance and control as a matched system. Trial and error does not always work. Review this in Magazines and on the various forums. There are a lot of "Lessons Learned" out here. I for one have had to take a step or two back from time to time.
- What you like and I like are two different things. I do not care for 20" wheels, but they do look good. An identical car (power, suspension, etc..) with 20" wheels/tires will be slightly slower than a car with 18" wheels/tires. Not myth, just Physics. Rolling Mass of the 20" wheels/tires is greater than 18" usually. Yes you can get lighter wheels, but they are for racing not the street generally. Greater chance for warping, bending, etc. on the street. The track is a much more controlled surface, so no ruts, pot holes, etc to warp the wheel. Some will argue, but I have proven this in real life against similar Mustangs to mine.
Whatever you decide to do, research it to death (unfortunate you have to do this), talk to different tuners, read the forums, read the Magazine articles, talk to local Mustang clubs, then bite the bullitt!
You may have to take a step backward from time to time unfortunately. Good luck.
