Coupe vs roadster doors

I have a local car I can source some parts and I have thought about an extra set of doors to get for summer HPDE. Are roadster doors compatible? I assume 3.0 si coupe doors are compatible.

why do you need separate doors for HPDE? But yes doors between roadster and coupe are interchangeable.

Maybe doors themselves, but not glass...

My thoughts are to keep my stock doors in perfect condition.

Use another set to gut completely during good weather with lexan inserts like my e46 M3 track car, loose a bunch of weight, and practice building some carbon fiber inserts.

Just entertaining the thought. thanks for your input.

There is no way the glass is the same in both models. When I got my coupe I kept hitting my side on the corner of the glass. Something has to be different than the roadster.

Something like this?

Just make sure to retain the door beam.

I recall the glass being different. (Had 2 coupes and 1 roadster)

See this for verification

Thanks guys,
The roadster doors will work as i will not be using glass. I will cut out some lexan and make some inserts for trailering to the track in the summer. I imagined "gutting" the doors just as in this post before.
