Sport Progressive Rear Spring Specify 1" or 1 1/2 " lowering.
A set of new coil springs for the rear suspension of the Opel GT. This is a pair of progressive rate springs that will lower the chassis. Choose either a 1" drop (2.54cm, which is a good match with our #3062 intermediate front spring), or choose a 1 1/2" drop (3.80cm, which is a good match with our #3001 front sport spring). Powder coated, manufactured in the USA. (Note: Will also fit some Kadett B models).
