There's always the grand debate between drivers out there who comment on
suspension systems by "seat of the pants" tuning and feeling. And while I can respect that, it is just not reliable.
Suspension manufactures spends 1000s of hours tweaking their systems to work best together. When you start playing the mix/match game, even though you might think your car handles better, you may be for worse in the end. All the constant tweaking/swapping having numbed you to the fact.
I always suggest sticking to a complete
suspension package if you're serious about on road performance and even mild track days. (road course, not drag)
Multimatic, the company who originially developed the FRPP
suspension package, did a wonderful job. The kit gives your street Mustang a good look and much upgraded handling. All while not being too bouncy/jouncy.
It even does a darn good job out at the track,
for what it is.
Any one who pieces a
suspension system together, you really can only get proof of such a setups performance with track times. You need to go out to the track, run laps and see if the Frankenshock setup really did work better. If you just want a lowered ride and soft
suspension, get some Steeda Ultra lites and some Monroe Sensatracs! (I kid I kid!)
It's easy to make a car feel more solid or tight yet compliant by mix/matching. But you have to be able to quantify the results to justify throwing away 1000s of man hours of testing.
I've installed and driven on many
suspension systems in various FOX bodies and SN95s over the years and this is what I have learned. In the end, a well tested and developed "system" always performs better. Street and track.
