Installed Road Magnet Springs
Hi guys, over the holiday weekend I installed Road Magnet springs on my car.... About 1.5 years ago, I used to have CM springs. I liked the drop they provided, but the ride was terrible due to the soft spring rates. I decided to go back to a stockish ride height, and installed a low mileage set of SS/TC FE5 springs. The SS/TC springs handle/ride like a dream, but the wheel gap started to bug me again. So I started researching all the lowering & performance springs for our cars. After weeks of reading threads and comments about different springs, I limited my choices down to two. It was between YYZ springs and Road Magnet springs. The YYZ's just didnt give me the drop level I wanted, and the price wasnt in this years car parts budget. So Road Magnets it was. I contacted the company, and they turned out to be great people. They are a U.S. company, and only use U.S. materials. Their parent company has been designing/producing coil springs since 1907. The reviews I read on their springs for the Cobalt were all positive, and that sold me even more.... Here are some of the specs, along with a link to the thread about the test car used to design them.
- High Quality, high tensile chrome silicon spring wire
- Double shot-peen to reduce stress & fatigue
- Cylindrical design helps achieve consistent, accurate spring rates
- Durable powder coating
- Made in the USA with only USA sourced materials
Drop = 1.0" front, 1.5" rear
Spring rates = 310 front, 260 rear

Below are some pictures of my car. Mind you I took the photos right after install, and didnt even drive with the new springs yet (roads are crappy here right now), so they will settle a tad. I will give a review once I get a nice clean day to put them through their paces.
On a side note, I don't want to hear I should have gone with this or that spring. I did a lot of research on springs, and these were my choice that best fit what I wanted. I'm not known for following the herd in terms of modifications....
Other suspension mods on my car:
SS/TC struts
Koni rear shocks
Powergrid endlinks
Moog cabs
Hardcore rear sway bar

Did you get their Ion springs? https://www.roadmagnet.com/products-by-make/chevy
They don't have a listing on their site for CSS springs... https://www.roadmagnet.com/products-by-make/chevy

Contact them personally. That's what I did.

I didnt snap a good full side shot. I'll get one for ya next time the car is out.
Umm, they were $220 shipped. They are up to $250 shipped if you opt for a different powder coat color on the springs. I just went with the standard blue color.

I didnt test them yet. My car is spotless and the roads are gross so I'm going to wait until they get a little cleaner after the snow melts.
I listed the springs rates for my Road Magnets, I think the springs rates for YYZ's are on CED's site.
From what I read, the ride is very good.
Yeah, all the reviews for a lot of other platforms seem to rave about the quality of these springs.
I must say just from installing them and working with them, the quality is def top notch.
They came in a nice package wrapped in plastic with some info sheets and a registration form.
They have a nice warranty as well.
My CM springs came in an unmarked box not even wrapped or packaged nice with no information at all about the springs.

The Konis and the hardcore bar were the most noticeable changes in terms of handling thus far.
I cant wait to test the new springs out once the roads dry up a bit.
I would like to stick with the 45s, but I had rubbing issues in the rear when I used to have CM springs. That was prob due to the soft spring rates. Offset of my wheel are +38.
I'll do some testing with these tires and if they dont seem to rub with the Road Magnets, I'll stick with 45's. I like the beefier looking tire.
Thank u sir!

it really comes down to what you plan on doing with the car.
if you just cruise around town and the 45 will fit without hitting anything , then it will be a little more cushion for the ride.
If you plan to do any autox/track stuff then i say bump it down to a 40 and runn a narrower tire to reduce the roll over when cornering.
but in Stage's case, i think the 45 he is running will be more beneficial.

Spring Rate / Lowered Height: SS/TC vs. YYZ v5's vs. Road Magnet
GM SS/TC front: 154 lb/in linear
GM SS/TC rear: 160-228 lb/in variable
YYZ front: 138-265 lb/in variable
YYZ rear: 105-325 lb/in variable
Road Magnet front: 310 lb/in linear
Road Magnet rear: 260 lb/in linear
I'm guessing the amount of drop has something to do with the reasoning/design behind the rates so I don't think that can be a true apples to apples comparison.
From what I gather, the YYZ v5's drop the car approx. 13/16" front, 1" rear, so you are getting roughly .2" lower front and .5" lower rear with Road Magnet. Roughly.
Also I called Sean at Road Magnet to confirm that the spring rate for the front/rear that Staged07SS posted weren't reversed, he says it is posted correctly. I thought they were reversed comparing to SS/TC and YYZ's.
