I have been searching and reading conflicting responses on the SS TC springs and whether they lower a LS. I have read a 1/4 of an inch and 1 inch. Some say there is no difference. Does anyone have the lengths of each spring to see what the difference is? I have a 2009 LS and I am looking at 2009 SS TC springs. Thanks.

 

They will lower your LS about 1 inch. If you look at the quoted drops for almost all Cobalt springs they give the specs for the drop on a non SS model. The SS gets dropped 1 inch less than the LS Cobalts on the same springs so therefore the SS springs will lower your LS Cobalt 1 inch over the stock LS springs.

 

dont know LS. SS/SC free length front is 330 mm, TC is 310 mm. Rear SS/SC is 300 mm, TC is 295 mm.
FYI 300 mm = 12 inches...

so you can probably conclude based on free length that the TC trims at a lower ride height than an SC, and we know that GM say an SC trims ride height 10 mm less than an FE3 car....

 

Thank you for the quick replies as I am purchasing a set this week.
