Does anyone know the difference between the IROC spring and Berlinetta spring. I have an 85 Berlinetta, I am getting ready to put in rear springs Moog # 635v. I ahve a question about the front springs though, as they are my next project.

Moog lists a 5276 for the berlinetta and #5662 for the IROC. Auto Zone stocks the Iroc for $37 the 5276 is not stocked and costs more. They also list a Z28 spring #5608 for $60.

What difference will these make in height or ride?

Thanks

 

ride height won't change from factory height. if yours are wor out, it wil raise the car back to factory height. the differences in springs are the rate they compress. the z28/ iroc are stiffer than the berlinetta.

 

where did you find the moog info.
