Thread: Road Magnet Discount Code

You have read incorrectly Stratton.

The RM's do drop the car 1/4 inch more in the front. A negligible difference in my mind, it might be important to some folks.

"Better" is a judgement call, the two (2) types of Forum Exclusive Springs are different.

The RM's are a linear rate spring and a bit stiffer than the progressive rate Hypercoil Gen II's.



The Hypercoils are a progressive rate spring and a bit softer than the RM's.


On the initial "hit" on a pot-hole, the Hypercoil springs start at 110 and progressively get stiffer the farther they compress, ending up at 290.

On the initial "hit" on a pot-hole, the RM's start at 325 and stay there throughout their travel.

The RM's might be preferable for a street car that is more prone to autocross or track duty. Benito Malito certainly thinks so.

The Hypercoils will undoubtedly be more comfortable than the RM's on the streets, and can certainly handle an autocross or track duty with aplomb. (Dave Coleman and Mike Kojima certainly thought the Hypercoils mated with AGX's was a solid track-worthy suspension.)

The RM's (on this current coupon) are just over $200. The Hyperco's are just over $300. "Only" a hundred bucks difference, but that means the Hypercos are actually about 50% more expensive than the RM's. That makes zero difference to me, but could easily be important to other folks.

What is better to me? The most comfortable performance spring for daily driving. Ie....The Hypercoils. No question.

What is better to Benito Malito? The RM's, no question. He prefers their "more predictable" and stiffer nature.

What is better to you for your driving habits, roads, budget, and preference?

However, there is no "best," the Hyperco's and RM's are similar, certainly close in specifications, but different. Each has their own unique characteristics and driving experience. It is about what you prefer and your goals and uses for the suspension.

^^^^ Good synopsis, Shawn. Main point is that, between Road magnet and Hyperco, there is no right or wrong choice, just a matter of personal preferences.

A factor in my choice was chassis stiffness. The B13 has a lot of flex, but seems to be fine with 325/250lbs. B14's have a stiffer chassis and can tolerate more spring rate before the ride suffers.

My B13 has sub frame braces and fender braces welded in so it can take a lot higher spring rates and still be plenty comfortable.

So for me Road Magnet is the best choice, and at this price, too good to miss.

Another thing to take into consideration is passengers. car's handle different when they are loaded up.

Either way both spring options are good, but for the discounted price of the RM's atm you cant beat that with a stick!

Good points.

Like you my B13 chassis is nowhere near stock. Fully-overkill-foamed, fender braces, IKEA brace, Octotat 3-pt rear strut tower brace, and Cusco 2-point front strut tower brace. Which for me is not about running higher spring rates, but extracting the maximum comfort and performance out of the most comfortable performance springs.

However, a braced-and-fortified chassis certainly allows for a higher spring rate with the same level of comfort as a lower spring rate (all else being equal).


Agreed. With the coupon, this deal on RM's is a raging bargain. Amazing that you can get such good performance springs so inexpensively.

^^^ Absolutely. I don't know why the importance of chassis stiffness is so ignored.

People continue to put money and effort into suspension modifications that can't reach their potential if the car twists like a pretzel.(and all factory B13/14/15's flex)

In any situation, from straight line drags to corner carving, the car with the stiffened chassis always has the competitive advantage. Like you point out, there is even an improvement in ride comfort.

Installing sub-frame braces/fender braces was the smartest modification I've ever made.
I'd like to follow your lead and foam fill someday. I'm thinking the foam not only stiffened, but made things quieter too. Double advantage?

Agreed on all of the above observations. If I buy another B13, the first thing to attack is the chassis fortification. It is the foundation upon which everything else is dependent.

Yes on both stiffened and quieter. Double advantage, no doubt.

Once I get my CSK's back from Truechoice (Koni Repair Center) and installed with my Hypercos and Ultra-Fortified Chassis, I'm *thinking* it will be both glued to the pavement and comfortable as hell. Possibly more comfortable than a fully stock suspension.

Further, if someone was committed to the RM's, chassis fortification would be a very good step towards keeping the vehicle comfortable while allowing the stiffer RM springs to do their thing.

Got my Road Magnets last night!

First thing I noticed was the quality, from the thickness of the springs to the powder coating.

I knew everyone on the forum has been happy with these springs but I learned things I didn't know from an enclosed brochure.

The springs are actually made by a US company that has been manufacturing springs for over a 100 years.

The springs themselves are:
* "high quality high tensile chrome-silicon spring wire for superior strength and durability"
* "double shot peen processed to reduce stress fatigue"

"The springs are manufactured to very close tolerances to consistently produce highly accurate free length, rate and squareness."
This keeps the car level and the balance consistent in all directions, and prevents variations in cornering."

It also seems they make springs for more than just street cars, as there was a reference to the Bertil Roos Racing school, who use custom designed Road Magnets on their Formula 2000 racing cars. They wrote "More consistent performance is key for our decision to standardize on Road Magnet."

I really liked their warranty statement which said:
" We expect you want to drive your car. Most warranties suggest their lowering springs are for show purposes only. Road Magnet springs have been designed to perform on the road. We stand behind the quality and performance of our springs. In the unlikely event of a failure you may send them back for replacement or a full refund."

So.... I ordered these based on the recommendations of other forum members, and because I wanted a higher spring rate than the Hypercos, but mostly because the coupon price was too good to pass up.

Now that I know more, I realize I got more than my money's worth!

Hi all. I just wanted to update this thread. I did get my Road Magnet springs. The hardest part was waiting so long for the agx struts. They were on back order at the manufacturer for up to six weeks. I ended up finding some in stock and at some good deals. I installed it all this weekend with the help of another forum member. Here are a couple cell phone pictures.

Definitely gives the car a nice slope, from the rear down to the front. Looks good and Road Magnets are serious about performance too.

What are your driving impressions on the improvements in handling? Had a chance to push the car hard yet?

By the way, nice wheels. I used to have a set, Enkei RPO2. Only weigh 12 pounds apiece for the 15X7 but they're really strong wheels.

(Thread Jack) I'm actually looking for some Enkei RPO2- J.
