Lowering springs for convertible?

All the makers of drop springs list the same set of springs for the coupe and the vert. How can this be? The vert has almost 400 pounds on the coupe, they have to come with stiffer springs right?

With the Pedders springs you will want to use the 1" drop rear springs due to the weight,it makes for a nice drop on the vert.

Well we don't make a specific drop spring for the convertible. With the extra weight of the convertable top you will find that the car does sit a little lower than a hard top with the same spring, but our 1.25" drop kit will still work as advertised... it will just sit a bit lower.

If you're looking for the ultimate in ride height control you should probably look into coilovers. Drop springs do indeed work for the Verts, but they will sit a little lower than their hard top counterparts.

We offer a convertible specific spring for the Camaro.

http://www.hotchkis.net/2011-convert...l-springs.html

Hotchkis Sport Coil Springs for the 2011+ Camaro Convertible offer a sleek lowered stance, dramatically improved handling and superior driver control thanks to a lower center of gravity. Our engineers poured over computer modeling and track testing data to create the ultimate new Camaro spring that improves handling while offering a sporty yet comfortable ride. Hotchkis Performance Springs were developed as a complete front and rear balanced system, giving the Camaro an aggressive stance and Corvette-style handling, especially when combined with Hotchkis Sport Sway Bars. Precision wound in the USA from the highest quality high tensile steel, they are finished in Hotchkis' durable gloss powder coat.

Features:
•1" Lowered Stance
•Higher Performance Rates, Front 210lbs/in, Rear 440 lbs/in
•Cold wound high tensile steel for strength.
•Durable powder coat finish.

Benefits:
•Sleek, lowered stance.
•Dramatically improved handling and control

Pedders 220035 rear coil carries the extra weight of the vert perfectly, as Bruce already posted. They also just happen to be available in a complete package through Bruce at this link.


They just happen to be ON SALE in a great suspension package. http://www.camaro5.com/forums/showthread.php?t=230468

Birth of a Lowering Spring: Inside Pedders Suspension



Pedders Suspension is a brand that might be familiar to enthusiasts of the domestic aftermarket. For more than six years, Pedders has offered suspension components for Chevy Camaros, Ford Mustangs and Pontiac GTOs. What most don’t know is that the company is far from an upstart in the chassis game. Pedders Suspension has been in business in their home country of Australia for over 60 years, starting back in the mid-1950s rebuilding shock absorbers.

Headquartered in Keysborough, just outside of Melbourne in the state of Victoria, Pedders Suspension has a unique business model for their domestic market. Their products are distributed solely through franchised Pedders Suspension retailers, of which there are over 130 in Australia. Think Jiffy Lube, but for suspension needs that range from the inspection and alignment all the way to polyurethane bushings and coilover swaps.

Here in the U.S., Pedders’ business model is completely different, utilizing a more traditional distribution route. In their short time in the American market, Pedders’ products have been used by GM, Lingenfelter and Saleen. Pedders sells the gamut of chassis components, including coilovers, polyurethane bushings and CV shafts, but their core product is springs. In fact, Pedders likes to refer to their manufacturing facility as the “World’s Best Spring Plant.” While that’s up for interpretation, having witnessed the birth of a spring, firsthand, we can attest that quality is very much at the core of their values.



Here’s how Pedders Suspension springs are made:

Birth of a Pedders Spring - Step1

Step 1:
Pedders’ springs begin life as steel from BlueScope Steel, an Aussie company headquartered in Melbourne. Instead of sourcing cheaper materials from China or India, Pedders insists upon using steel that is ISO accredited.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 2



Step 2:
For heating of the metal rods, Pedders relies on gas instead of electricity. With the latter, dips and irregularity in power can cause inconsistencies in the metal. Each rod is baked close to 980 degrees C.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 3



Step 3:
After the steel is heated up to temperature, the glowing rod is then coiled around a mandrel. The solid steel mandrel does not flex or bow with repetitive use. Pedders has more than 100 different steel mandrels in varying shapes and sizes for varying applications.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 4



Step 4:
The next stage in the spring production is quenching, a process in which the hot coiled steel is cooled by oil. The spring is still soft at this point, lacking any memory.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 5



Step 5:
Once the spring is cooled, it goes back into the tempering furnace where the coils are cured. Temperatures are adjusted to suit the gauge of the wire—the thicker, the hotter.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 6



Step 6:
After another cooling phase, each spring is ground to appropriate size and fitment.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 7




Step 7:
For the final step in strengthening the steel, each spring is shot peened with military grade shot.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 8



Step 8:
Pedders scrags 100 percent of their springs. Scragging is a quality-control process where each spring is fully compressed, testing its load for up to 2 mm in variance.

Birth of a Lowering Spring: Inside Pedders Suspension - Step 9



Step 9:
Before they are boxed and shipped around the world, the springs are powder coated. Powder coating gives a spring its brand-distinctive color and protects it from the elements.

The wheels are ADV One Track Spec 5.0, 20x9 & 20x11, the rear spoiler is a MPD1. I have lots of pics but I travel a lot and they are at home. I had a thread on the wheels a while back, you can search for it under my user name.

I had BMR lower spring for 3000 miles, during that time , I checked alignment 3 times, every time springs get lower cause out of alignment cost $300. I am finally switch to KW v1 coil over, going to check alignment next week to see what happen.

At justice Pete.. I have to challenge the heating of metal being better by gas vs electricity inverter based metal induction heaters are far superior than any gas fired oven. Inverters don't care about irregularities in power. Since the early 80s inverters have used power factor correction caps. These induction biased heaters are accurate to the .000 I have to believe that a gas regulator can be dialed in that precise. I've repaired the power supply or inverter on many different type of metal heaters for various applications far more sensitive than a spring. Not to mention the waste of fossil fuel that big ass oven uses. These 3phase inverters pull less than 12amps per leg when heating pipe to over 1200f. They can heat a 12 foot 12 inch dia. Pipe in seconds accurate to the .000. This pipe handles the steam from a steam power station.
