In my quest for springs for my 13 gt vert that are mild yet beneficial, I have come across these from Steeda:
Boss Lowering Springs
555-8245 - Steeda Boss Lowering Springs - $279.95

They drop the front of the Boss by .2 and the rear by .8, very mild but that may be different on a vert or standard gt?

Has anyone tried these springs and if so what is your opinion?

 

The boss is already almost an inch lower in front than a standard GT and .1" lower in the rear, so the drop is quoted from those measurements - i.e. the drop is akin to their other springs, although I'd guess the spring rate is higher considering the Boss's intentions, but I didn't look at the link to verify that...

 

Thanks for the info and you confirmed what I suspected that the Boss is already lower than the standard GT, so with these springs a GT has a potential of up to 1.2 drop in front and .9 in the rear. I am looking for the opposite, less than 1 inch in front and about 1.2 in the rear.
That's why I like this forum, it helps to ask question from knowledgeable people.
Thank you

 

I put hotchkis sport springs on our 13 Boss, the drop is perfect and eliminated the rake that I didn't care so much for. If you want some pictures of the setup please let me know. There is a couple of 13 Boss' running this setup. Drop in the front is around .4 the rear is about 1.2 inch leveling the car out perfectly. I'd be glad to help you out or answer any questions you have.

No problem man..

There's been some good feedback from the Hotchkiss stuff - I think they would be worth a look from you. Or possibly a combination of the Hotchkiss front springs and 55D rears?...

 

If you install these on your GT, Steeda recommends adjustable dampers.
If you put them the way the are without it would be a harsh ride. Boss lowering springs are more for performance then looks.

 

On a regular GT our Boss 302 springs will lower the GT 1 inch in front and 1 1/4 in the rear, however the spring rates would result in ride quality that could be considered a bit rough with the stock shocks and struts.

If you have a Boss 302 the factory shocks and struts handle this well, but for a GT we recommend not using the stock shocks and struts with these springs.

 

I beat ya to it.

 

LOL, snooze you lose....

 

Here are some pics of an 11 and 13 installed with Hotchkis springs. The 55d rears from what I understand are just stiffer springs without offering much of a performance gain.

 

Really like the Hotchkis setup, and appreciate the info from Jason at Hyperautomotive.

I also thank Steeda, they sent me a PM advising that the Boss springs would not work on a 13 Gt vert. I really think that was above and beyond for a auto parts company. thanks!

 

Here is a picture of my 2013 Boss 302 with the Hotchkis springs.




The ride quality is great and soft like stock.

What's this??? Ohhh just my 2013 GT Convertible with Ford Racing K-Springs. Please excuse the old picture. :-)

 

I believe they are of the same rate as the stock (Brembo) rear springs but sacrifice half an inch of jounce room for a little diminution of the wheel gap.
