IIRC it is because it will make a the spring rate feel softer. You take away the bind and the rate goes down. That said I am still running the same springs I had before (BBK lowering springs) and my car handles and rides fine. The MM springs are on my to do list, but they are not urgent. IMO

 

I am running Tokico Illumina 5 ways, from what I gather a lot of other guys use them with similar setups to mine. They are a nice damper for the $$. My car would not really act bad unless I pushed it OR if it hit boost hard (like on a cool night). The fact is that 1st and 2nd are near useless with my regular street tires, but when it broke loose in 3rd at about 40 while I passing another car (sideways LOL) I knew I had to fix it. Depending on your power level and how you drive it might never be an issue, but my bet is that if you are bothering to upgrade these parts, you will at some point push the car, it's what we do

 

gotcha, i read about it, i just forgot why n stuff.

but yeah, i want to have the setup in the pic i posted, only retain the stock location sway bar and retain conventional springs. my car wont be built or ***** to the wall enough to need that swaybar or coilovers... my goal is a kenne bell powered 302, with a modest HCI and maybe a lil giggle gas

 

I'm running a 347 on a 100 shot and well into the 10's and never had it break loose, but then again that's on a straight line, on my ride home I live on a winding road and love to power into it like I'm road racing amazingly enough it handles quite well for being set up for straight line racing

 

My bet is that your shocks and springs are where the difference is.

 

If you're going to run a lateral locating device then you might as well run a Watts link. Not only does it provide better control than a panhard, it lowers the roll center on the rear.

 

link?

 

just the standard lakewood 50/50 90/10 set up

I know they make them for my car, not sure about all the year Mustangs though. I imagine it covers them all, though I could be wrong.

 

that thing is wild looking! why is it better? it is double the prove pf a panhard bar and on the corral mentions you could still use a torque arm
