I ordered this springs for my 2000 Camaro Z28 to replace the factory springs with 55K on them. I paired them up with new Bilstein struts and shocks and KYB strut mounts and plates. I got 1-5/8” drop in front and 1-7/16” in rear. Advertised at 1-1/4” all away around drop. The car rides better and handles better. Only issue is my long tube headers and crossover pipe are close to ground, have to pay more attention while driving. On a stock exhaust car this wouldn’t be as big deal. The car does look much better and handles better so would recommend this product.
