quick questions about EG parts compatibility
 

Due to the differences in weight in EG models ...

1) will OEM springs from a sedan be compatible with a coupe?

2) will aftermarket front rotors (Powerstops) from a sedan be
compatible with an Si hatch?

Are glove box doors interchangeable between hatches, sedans, and coupes?

1) All EG springs are interchangeable. The spring rates vary between models though

2)All Canadian EG's have the same front brakes 9.45" Dia, except for the EX-V sedan(very rare)which had the 10.25" Integra sized rotor.

3)Glove box doors are interchangeable between models in 2 differentways:

a) Models without passenger side airbags will accept gloveboxes of models with and without airbags.

b) Models with passenger side airbags will ONLY accept gloveboxes of models with airbags.

so if I sold someone with a coupe, my sedan springs, would his stock ride quality be more or less the same?

EG sedans came with 13" wheels and small rotors.
The Si had 14" wheels and larger rotors. AFAIK
