I just noticed yesterday while the car was on the lift that there was a 4-5 inch splinter hanging from the front composite spring.
It is cracked enough that I can see the fiber under the surface of the spring, probaby an 1/16 inch thick sliver.

There are no signs of impact fore or aft, and definitely no off road excursions.


How serious is this and are these types of cracks prone to getting larger or catastophic failure?

Sorry I didn't have a camera to photograph.

 

They are not common but do haapen. The front spring on my Coupe did that. I trimmed the splinter and drove on it for several months. It did not progress further. I eventually replaced it with Z06 springs.

 

i would replace asap...

i broke my rear leaf going about 75-80 mph and almost lost control......

 

Same thing on my 05. What I'd watch for is your front end getting lower. Find a way to measure it, wheel well, rocker panel, etc and measure again in a week or when you drive it. Mine got to below 24 inches at well. Replacing it is easy and springs are easy to find. I bought a used Z51 spring for under $200. Most folks say some type of engine or wheel cleaner is what made it delaminate.
