I have tried to lighten my car everyway possible and realized that the rear hatch as got to weigh in at ~50-75 pounds. Is there any lighter substitutes that will still be able to handle a rear spoiler and not crack off. I am looking at the older Feed rear wing but I want to make sure that a lighter hatch will not break if a wing is attached.

I don't know how well that makes sense (or that )
Thanks

 

i dont know about 3rd gen rx7s sry

 

There are Lighter hatches (CF or FG) hatches available. However,
By far the Heaviest part of the hatch is the GLASS - MAZDA Comp has Plexiglass replacments available that should save at least 10-15lbs without changing the frame

 

C-WEST makes a lighter replacement for $1,576.

go here and then search fo rthe rx7.

its almost to the bottom of the page on the right

 

my friend used to have the C-west fiberglass rear hatch. The stock one is actually lighter. I think the stock one is as light as it'll get, it's made of aluminum..

 

Greddy built up a show car with a custom rear hatch that had a small z06 style window.

 

Flexalite (sp) also makes a hatch window. Mazdacomp may have a hatch and I've been looking into getting the CWest Hatch.
I can't be heavier then stock.
