This is a little off topic, but why exactly are the coil overs lower in spring rate. I never really understood the entire point of that. And is it better in their case to be lower?

How often will you be tracking the car?

This is due to the revised location of the spring vs the OEM location? It appears from a previous post, the HDs max out around 350 lb/in front and 225 lb/in rear.

I retract the statement about not knowing someone who runs them

This is from another post:

"I called MM the other day and they strongly recommended not to do rear coilovers if im going to drive the car on the street. They said it would be too rough and i wouldnt like it at all."

To run rear COs, or not...hmm

I'll estimate 3-5 times a year, although I tend to corner aggressively (within reason) during daily driving.

Full time daily driver, including winter when I run Michelin Xi-2s.

15 minute daily commute, and 250 highway miles on the weekend (long story).

Is this your daily-driver or just like a weekend car?

Any concern about bump-steer when lowering with coilovers?

MM has on/off said not to run CO's out back. I have run them for well over 4 years and no issues. Their position, as I understand it, is one of being "un-necessary" for the street and wears out too soon. I have not found this to be the case and have no issues with them. They offer better control of the rear axle and improved freedom of movement, being the shock and spring are in the same location/path of travel.

Jrad... yes, the lower rates are due to moving the springs outward of the pivot point of the control arms. it is approx. 2 times farther out up front and like 1/3 out on the rear. A 300# CO up front, is roughly 650# OEM spring, in terms of stiffness.

Do the comparisons between the two setups' benefits remain the same when adding a PHB/Watts Link and TA into the equation?

Jazzer The Cat

The WL or PHB with TA are absolutely HUGE upgrades in lateral grip replacing the Mustang 4-link. This is going to be an improvement, regardless of what spring set-up one is running. Do this upgrade on an car with OEM located springs and just goes to the next level with CO's. In my case, I went CO's, PHB, TA all at once, so I cannot really explain the individual changes for each of these items

If you are serious about carving corners, and you should be if you are considering a 3-link, you will end up going beyond what you have on your list thus far.
