:scratch: Ok, I posted that I am about to order a set, but went to the steeda site and found all 3 of these.

The info tells about the same on all of them."

Steeda 05/06 Sport Springs - Part Numbers: 555-8215/8216

Lowers the vehicle approx 1 inch front, 1 1/4 inch rear. The 05/06 Mustang sits high in the rear, these springs will give it a more aggressive look.
Maintans good ride quality for daily driving
Big improvement in handling and noticeable reduction in nosedive

Ultralite 05/06 Springs - Part Number: 555-8206

Lowers the vehicle approx 1 inch front, 1 1/4 inch rear. The 05/06 Mustang sits high in the rear. These springs will give it a more aggressive look.
High quality lower weight wire for less unsprung weight and less inertia for the best ride quality available.
Good improvement in handling and noticeable reduction in nosedive."

Nothing about the code E bit either.

What I want it to do:

Drop the car down

Not affect ride ability :angry:

Not have to buy the added caster/camber plates to get in the alignment. :bang:


"note, I do plan on getting a pan hard bar from BMR ( its cheaper than the steeda and should do the same job. MMFF has used them on several cars now and no problem."

One more thing, I have seen other springs available: FRPP, Progressive, etc.

Can anyone shed some light on these springs

 

I've been wondering the same thing, anyone know what the difference is?

 

I got a email from Brenspeed. He says the e code is a 2nd supplier and the ultra is not as stiff as the sport?

any one else add to this??

 

I can't tell you the difference between the two, but I can tell you I have the Steeda Sports Springs and BMR adjustable panhard bar set-up... The ride quality is definitely stiffer/rougher than stock (I also have 20" wheels), but the handling is much improved... Installation was simple and NO camber adjustment plates were needed for alignment... The final set-up lowered the front of my ride 7/8" and the rear 1 1/4"... Overall, I'm pleased with this set-up!

 

When it comes to lowering and stiffer springs you can't have your cake and eat it too. You have given up suspension bounce travel by lowering the car. The springs are stiffer to cope with that and if not you will be hitting the bump stops alot more as well.

Gus Irizarry at Steeda indicated to me the Sport springs are the same (rate and ride height). That the Ultralites are lighter and softer.

 

I am more into the ride height than heavy duty performance. I am not planning on doing any road courses in the future. I feel the Mustang sits too high as she is from the factory. I am now leaning real hard to the ultra lite springs...does not hurt they are 50 bucks cheaper.

I was going with the steeda panhard brace, but it does not look as adjustable as the BMR. I may go with the BMR due to that fact.

 

Understand your motive. Just recognize it will not be any smmother or softer than stock.

 

Seems to me the only way you are really going to know how the differing performance is by comparing spring rates?
You could compare the rates to your stock springs get a bit of a feel for the change.

 

Got this info from Steeda a few months ago:

"Sport springs are the same. 1 inch lowering. Same spring rate. Rate is 200lb front, 175lb rear.

The Ultralite sport springs are also 1 inch lowering, slightly lower spring rate at about 195lb front, 175lb rear. They are also a lighter weight wire for less unsprung weight. This reduces inertia. The slightly softer rate combined with the low inertia make the Ultra-lite sport springs the best choice for ride quality.

The street/comp springs increase the spring rate to 225lb front, 185lb rear. Also about 1 inch lowering.

For reference, factory spring rates are 165lb front 142lb rear for hardtop, 144lb front, 122lb rear on the convertible."

 

thanks paul

The spec sheet I have shows(GT coupe) Fr spring rate at 136.5/wheel rate of 170 and Rear rates of 142/ 170?

Just wondering because I'm having demo springs installed for the autocross season with rates calculated as a % of these rates.

 

What spec sheet are you referring to?

I have the same one. I agree with your numbers. But the ones I cited above were the numbers given to me by Gus @ Steeda and he swears that whats they actually are. What can I say?

[img]style_emoticons/<#EMO_DIR#>/headscratch.gif[/img] I guess when I have my new springs installed, I'll have to get the stock rates measured.

 

Anyone have a pic with the Ultralite springs installed? Or is it 'exactly' like the Sport?

Seems to me, unless your autocrossing, the Ultralites are the way to go.
