Are the motorsport c springs the same as the bullitt springs? Do they have the same spring rate and drop?
No...The bullit springs are specific rate & the c springs are progressive. The drop is different also. Bullit will lower the car 3/4" front & rear, but the C springs drop the car 1.5" in front & 3/4" in the rear....
