[BMR Tech]

Most people don't realize how much work goes into manufacturing top-quality springs. BMR Suspension offers a LIFETIME guarantee against SPRING SAG.

Here are the manufacturing steps used to make BMR 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. I say they know a thing or two about making springs.

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.

I have a few questions for you.

I just ordered your upper and lower control arms to try and help with the wheel hop on my 2012 gt. Would drop springs help with my launch at the drag strip?

How much of a drop is on your springs from stock?

Would I need any other parts such as mounts, struts or adjustments to use them? If so what do you recommend?

I have the brembo set up which comes with a spring that is a bit more firm, how would the feel of your springs be in comparison?

Thanks in advance for the feed back you may have. I ran some of your stuff on my 08 g8 gt and look forward to upgrading the mustang.

Thanks for your support! The combination you purchased should alleviate the wheel hop. Did you happen to get the Upper Mount as well? (UCM002) Our springs will also help combat wheel hop, and have proven themselves at the drag strip.

How much of a drop is on your springs from stock?

There are variables that come into play, however the average drop on the 2011+ GT is slightly over an inch on the front, and almost 1.5" in the rear. We have a picture of a 2011 GT on our site:

Would I need any other parts such as mounts, struts or adjustments to use them? If so what do you recommend?

I generally recommend upgrading to GT500 mounts, as well as a quality set of adjustable front struts for maximum performance. If the customer does not want to spend the extra money on the struts, I recommend atleast installing new upper mounts. We sell them, and they are easily acquired at your local Ford Dealership.

I have the brembo set up which comes with a spring that is a bit more firm, how would the feel of your springs be in comparison?

Our springs outperform the Brembo spec, and provide a similar ride with a more aggressive look.

Thanks in advance for the feed back you may have. I ran some of your stuff on my 08 g8 gt and look forward to upgrading the mustang.

No problem! We appreciate your support! Let me know if there is anything I can help you with! Keep an eye out for our upcoming sale too.
