BMR Lowering Springs - How It's Made

[BMR Suspension]

BMR is a few weeks away from launching our Lowering Springs. All BMR springs including our 2010 Camaro springs have a LIFETIME WARRANTY against spring sag.

Spring manufacturing requires expensive capital equipment, so BMR outsources this activity to a company that specializes in spring manufacturing. Spring manufacturing is a fascinating process, so I would like to share some facts about our springs:

1) BMR springs are manufactured from chrome silicon high-tensile spring wire. This is the best spring wire available for automotive applications. Most NASCAR teams use this type of spring wire for their designs.

2) Every BMR spring is computer tested as the last step of the manufacturing process. Every spring...not just a sample from each batch. EVERY SPRING!! Each spring is loaded in the spring tester at the factory. The spring is compressed and the CNC Load Cell measures the force for a variety of spring lengths. The computer takes this data and compares it to the BMR quality specs. Bad springs (if any) are kicked out and the good ones are sent to BMR. Per our requirements, the test data for each and every spring is electronically sent to BMR.

3) BMR springs are cold wound on a CNC Coiling Machine. The CNC coiling head can adjust the spring diameter in real time to ensure that every spring is the same as the other springs. This guarantees that your right spring matches your left spring!!

4) Every BMR spring is compressed solid at the factory. Not once, but twice. This gives the spring its permanent set...and guarantees NO SAG. This allows BMR to offer a lifetime warranty against spring sag.

5) BMR springs are stress-relieved at 750 degrees F. This ensures that most stresses induced during the winding process are eliminated. This process is necessary to achieve the repeatable high-quality product that BMR offers!!

6) All springs are shot-peened to eliminate residual surface stresses. Many spring manufacturers skip this step. BMR insists on this operation as part of our spring manufacturing process.

A few more notes:

1) BMR springs are Proudly Made in the USA!!! Costs are minimized and quality is maintained using CNC manufacturing equipment. Shipping costs are low. No boats. No planes. No custom fees passed on to the customer. Just good old American manufacturing ingenuity!!

2) BMR springs are manufactured by a spring company that has been making springs for over 140 years. Think about it...when GM was founded in 1908, this spring company had already been making springs for 40 years.

3) BMR springs are manufactured by a family-owned spring company. The same family has owned this company for 140+ years (6 generations). No corporate bail-outs. No passing the buck. When your name has been on the door for 140 years, you make sure that you own the best spring manufacturing equipment available.

What size drop do these springs give?

[BMR Suspension]

The BMR springs will have a 1.25" drop on all 4 corners. The front spring rate will be 220 pounds per inch and the rear spring rate will be 460 pounds per inch.

Hey Allan: Love your products. I am planning to change springs and go to heavier sway bars. Should this all be done at once or can I do one and then the other? Any problems with ground clearance? We have a steep driveway. When do you expect to have these available? I ordered your strut brace yesterday. Thanks, Bob

Thanks for the order!!

You can replace the springs and sway bars separately. Each one will improve handling, but the biggest bang for the buck is when you change both. The total installation time will be slightly longer if you do both separately, but not enough of a difference to worry about it.

The ground clearance depends on your driveway. However, the 1.25" drop will give you plenty of clearance (even on rough roads full of potholes).

The springs should be available in 3 weeks or so. However, I am pushing hard to get them sooner.

Any rough estimate on price on springs and sways seperately?

I think I'm going springs first for a while then I'll do sways lateer down the road.

[Berean]

Are they direct install or do you recommend modifications like cutting the bump stop?

[Kwik]

You can get pricing on sway bars at Summit Racing. P/N SBP-007 $359.95 for the pair. They aren't available yet. I think they show lead times a couple of weeks out. I believe Morano Racing had the springs on their site, but I don't recall the price. They are also a couple of weeks away. The parts that I have gotten from BMR are great.
Shop around for best price. Regards, Bob

I've been looking for some spring with a 1.25 drop, I just hope they don't cost an arm and a leg like the other 1.25 drop springs!

What's your definition of "an arm and a leg"?

I think you can find Pfadt for about $300. Pedders are in the $360 range. I've seen Eibach for right at $200. I got a set of Hotchkis for under $300 to my door.

$300 for a set of drop springs is the norm. That goes for most cars and not just the Camaro.

So...as long as you are willing to spend about $300 then you'll be fine. Eibach is going to be the cheapest though.

Not sure how much BMR's are going to be but if you don't have to have them right now then just wait a little bit because I'm sure they will competitively priced.

Do you know of any manuf that has lower(2" or greater)adustable drop(other than coilovers), like air bags for the 2010?

There is no need to shop around. BMR requires our distributors to advertise and sell our products at the list price. Ther list price for the BMR springs is $229.95.

$360 for a set of springs??? By definition, that is an arm and a leg!!

Sway bars are $359.95 and springs are $229.95. However, if you buy them as a package, you get a $50 discount.

The BMR Level 1 Handling Package will include a set of 4 springs and a front and rear sway bar. The price for the package will be $539.00.

[caverman]

Nice!

I knew you would be competitively priced.

Do you have a timeline on when your springs might be available? What about swaybars...any idea when they will be available?

We started selling them at Camaro 5 Fest. Rear sway bars are ready to ship now. Front sway bars will start to ship in 2 weeks or less. $359.95 for the pair.

As soon as you get a chance you need to have pics and info of your springs and sway bars posted on your web site.

I'm still probably a couple mths from doing sway bars but I'll be researching which ones during that time.

[Xanthos]

I know this is probably a dumb question, but are your swaybars and springs going to be available in black hammertone like most of your parts? I looked on your website but couldn't find the info.

[SSmoothie]

Are you Sway bars solid or hollow bars?

Swaybars will be available in red and black hammertone finishes, the springs will be available in red only.

Both front and rear swaybars are hollow. I understand their is controversy over "solid vs. hollow" swaybars. Both sides present good arguments but here is our take on it: Progress exists through advancements in technology. You won't find any OE using solid swaybars anymore unless the bar diameter is less than 1". It is not because it is cheaper (DOM tubing is more expensive than solid), it's simply more efficient and less weight.

We have put a lot of development time into what we think are the ideal rates for this platform. Since the Fifth gen has pre-existing understeer, we designed our bars with more rear rate bias to neutralize the understeer and balance the car. Our variable rates make it possible to use only the rear bar to correct the understeer or both bars to increase overall roll resistance. To accommodate as many variables as possible we make both bars adjustable so you have 9 possible combinations to choose from.

Our front bar is 1-1/8" diameter with adjustable rates:
50%, 110%, 214% stiffer than OE.

Our rear bar is 1" diameter with adjustable rates:
99%, 173%, 301% stiffer than OE.

Wow thats not bad at all, when can I order the springs I didn't see them on the web site?

[IROCanSS]

I have BMR "stuff" and I love it. Only reason I didnt go with BMR springs is I only wanted 1" of drop and Eibach ProKit was exactly that. I feel 1.25 was a bit much for my liking. I live down a gravel lane and dealt with dragging the gravel in my Corvette for too long to lower the Camaro that much!

I too fell $360 is a rip for springs. The Pfadt kit can be nad for $300ish all day. I fot my Eibachs shipped, to my door for $205 but I got 2 kits so there was a "deal".

[Mustang Killa]

So when and where can u buy the springs?!?

I just wanted to point out some changes we have made to our springs. After polling the forums and experimenting with different drop amounts we have decided to offer two different drop amounts. Our rates will be the same between the two part numbers but instead of 1.25" drop we are now going to do a 1" drop part number and a 1.4" drop part number. The 1" springs are being manufactured as we speak and should be available in 2 weeks, maybe 3 weeks tops. For those wanting the 1.4" drop, we are still testing with this part number and they will be available later this summer.
Springs can be purchased direct through BMR or any BMR distributor (http://www.bmrfabrication.com/distributors.htm).
