I'm looking for some testimonies from individuals regarding which spring they would select between these 2 choices...

 

I've got the Super Sports and love them.

 

Thanks for your responses, it seems that HR is the winner of this one.

 

I also have the H&R's and they give a perfect stance... and the ride isn't too bad either.

 

This is what concerns me "ride isn't too bad!"
I'm leaning toward the HR Sport vs Super Sport for this reason.

 

Yeah that is why so far my decision is to go with the HR Sport.

Here are the specs for the popular (3) on a 94-04 Mustang GT

HR SPORT
490-575 (progressive) front
205-250 rear
Lowering range: 1.6 front / 1.5 rear

HR RACE
750-850 (progressive) front
260-280 rear
Lowering range: 1-1.75 front / .75-1.25 rear

HR Super Sport
700-760 (progressive) front
275-300 rear
Lowering range: 1.75 front/ 1.6 rear

 

It seems that the (3) springs I mentioned spec out at about the same lowering distance.
The main noticeable difference is the spring rate. If your intention is to do a lot of road racing and corning then I suppose you would want the stiffer spring. In my case I want a little bit of everything... I want it to have the bad *** lowered look, I want it to ride reasonable well for a daily driver, I want it to handle well when I need it to.

Initially before research I wanted the eibock sportlines cause they produced probably the most drop of all. I was told that going that low caused all kinds of other problems and that the lower you go, the stiffer the ride etc etc.
Then I thought well I would go with the HR Super Sports... Then Maximum Motorsports techs who claimed they tested all the springs and based on their many feedback said that the majority were not happy with them cause it made the ride super harsh like riding in a shopping cart. Then I was informed that because of the minimal suspension travel on these mustangs that the best thing to do was to go about 1.25 to 1.5 or so on the drop to leave you with enough suspension travel to allow for good handling and a decent ride quality.. This was my understanding anyway. So based on all that it pointed me toward the HR Sport. reasonable spring rate for daily driver and reasonable drop without going so low you run into other issues with handling characteristics and scraping etc.

 

I have a weak bladder from all the beer I have drank in my life so I need a bit of comfort from hitting those bumps ... (laugh). There's certainly nothing wrong with what you have gone with... Plus if either of us want to change all we have to do is get another set . Either that or coil-overs .

There's a guy I work with that has the coil overs on his 240Z. The car is so low you couldn't slide a dime under it. He is into that drifting stuff... For him, he loves it and it is his daily driver ...
