Default lowering spring differences

I'm looking for lowering springs but besides the amount of drop, is there a legitimate difference in ride? is there a soft-to-hard chart of the different brands? anything softer than stock? had to find by searching...

Spring rates determine the type of ride, the higher the rate the harder the ride but also the flatter the cornering. Springs are the strength of the system, and struts and shocks the ride control of the system. stiffer springs help you launch quicker do to less weight transfer end to end. and the same is true for for braking, stopping power is increased for the same reason. A good set of koni adjustable shocks improves the ride quality of a stiffer spring. You don't want a spring softer then what the car comes with from the factory. The factory suspension is adequate, but a set of aftermarket springs shocks and struts with sway bars really changes the car for the better.

Absolutely. What is it that you do with the car? Is this a daily driver or weekend car? Do you track it? What is it that the car doesn't do that you want it to do?

Look at the FRPP springs.
They offer several sets with varying drops & spring rates.
You can do a little study and decide exactly what you want.

I used the FRPP "B" springs because I wanted 1-1/4 to 1-1/2 drop and a softer spring (just a little stiffer than stock).
Then I do the dampening with the Koni Yellow adjustable shocks & struts.

Plus, since they are mass produced, the FRPP springs are less money than most competitors.

Cheapest isnt always the best way to go! "you get what you pay for" may apply here!

I have the Eibach Pro springs on mine, and I personally think it is the perfect drop for my needs. Any lower and I would be scraping everthing. Handles like its on rails.

The FRPP springs are not cheaper because they are a cheap product. They are mass produced on specialized machinery that is dead-nuts repeatable. The materials and parts are made here.

The foreign made springs have a lot of transportation costs added in and a lot of taxes & import/export duties too.

My point here is that you get better parts, much better materials and more bang for the buck by buying USA made parts.
You are getting no benefit by paying more for imported parts.

I'm running these UPR Pro Series springs on my car. They're made for us by Eibach, and they are made to the same specs as Eibach's Pro Kit springs. They drop the car around 1.5", which makes it handle MUCH better, but they are progressive rate springs so they have a pretty good ride quality. I highly recommend them.

When you lower your car, you'll need an adjustable panhard bar to center the rear end. But they're inexpensive and easy to install.

I would recommend our Ultralite springs (drop is 1.25" [F] and 1.5" [R]) and a set of swaybars for you.

That would provide just what you are looking for: lower ride but perfect for a daily driver, improved handling, and reduced body roll.

Not a problem. I sent you some links with our articles about how our springs and swaybars are better than the competitor's.

Good info. I've been wanting to do the same and needed to know what the basic items needed to lower the car. Anything within the $600-$800 range would be perfect

Shoot me a PM. I'd be glad to discuss some options for your purposes.

We are more known for our control arms and k-members than our springs. Like I said, our springs are actually made for us by Eibach. But Eibach springs are probably the most widely used S197 springs on the market. Eibach, UPR, FRPP, Roush, (and who knows who else) all used Eibach to manufacture their lowering springs. It's a huge chunk of the market.

Paul Brown is sponsored by Eibach and he won the GTS championship last year using Eibach products. Steeda's good too though.

At a minimum, shocks/struts, springs, and some form of camber adjustment (I will always recommend Steeda HD plates for street driven cars). If you have wide wheels/tires (285mm and wider) you will want an adjustable PHB. IMO lowering on $600-$800 is asking a bit much. Good shocks/struts are going to be about $450, springs $270 ish, Steeda HD plates, $270. That's just shy of $1000 and doesn't include the adjustable PHB ($130 IIRC).

As for what, I have Steeda Sports, made by Hypercoil, rears are linear rate 2.5" coilover springs in 175 lb/in, and fronts are stock sized, linear rate 200 lb/in springs. Drop is 1" front, 1.25" rear. With the Tokico D-specs, the ride can be a bit jarring even with the dampers full soft over rough bumps, but the streets here in Omaha are worse than some 3rd world countries so that isn't saying much. Over 90% of the bumps in the roads it's not unreasonable but occasionally you find one that really makes you cringe. A lot of that is the D-Specs, the rest is the awesome roads here...

After changing my springs I do recommend changing the shocks and struts at the same time, its a pain to do it twice. Also without matched shocks/springs the ride feels a bit bouncy.

I've just had a whole set of Steeda suspension installed this week. The car feels completely different, much less roll, dives, and car feels a lot more controlled and solid. I have the Steeda pro action dampers, sports springs, adj panhard bar, and upper HD mounts/plates. It feels a lot more "connected" to the road, feeling the dips, and such, compared to the floatier, more isolated feel of the stock setup, so the changes have all been very positive for the ride and drive experience. Plus....the car looks so much better lowered. I'll post up pics later on in a new thread. Basically, it's been a really great mod.

It depends on everything else you put in

For example.. my 1"/1.9" springs with nothing else rode a lot worse than my current H&R Super Sport 1.7"/2.4" drop with Koni STR.T
