Most street stock springs are stock apearing but you can always paint them black or the same color as your frame.

Smowrider, Try Day Motorsports, just click on the yellow banner, they have alot of springs. You might be ahead to call them and discuss what you need, they have been very helpful when I've called them. Hope this helps ...loojack

Performance Bodies has a great selection of springs that are made stock appearing for the very reason that the rules are written

Do you guys have an material data for these springs I was trying to calculate how acurate the ratings they give the springs with my spring rating machine. What I really need is the shear modulus, but if you knew what material is actually used, I think I could find the rest. I tried calling Speedway for some data, and the in the words of the tech guys "They're made out of steel." REALLY!?!? no way.....a 1150# spring out of steel, who would have thought????? Thanks guys.

All steel no matter of what grade or alloy has the same modulus. G, shear modulus=12 million psi E, tension modulus=29 million psi.

Speedway Motors has TRU-COIL racing springs. They are totaly stock appearing and are painted black.
Rates are from 925 to 1450 for fronts and 175 to 300 for rears. Rears have pig tail on both ends like factory.

Can those springs be cut down? I put the TRU-COILS in my 82 monte and the ride height increased. I don't think its bad as long as you don't cut them with a torch.

Remember when you shorten an coil spring you increase its rate.

Springs are rated on a constant (K). For example a 1000 lb spring needs 1000 lbs to move the spring 1". The rate does not change unless it is a progressive spring with unevenly spaced coils.

glentom is correct, when you shorten or cut the spring shorter, the spring rate will increase.

you guys are both right.
On a spring tester you only measure one inch of travel. But when you take a spring and cut it it does get stiffer.
Think about kids with their rice burners and when they cut the springs they go bouncing down the street.
If you wonder about a cut springs rate just plug the spring rate tool here on the tools page.
