Metal removal at rear, opinions

[NoHachi]

Have you had the car on the scales yet? Any idea about current weight and front bias?

My guess is you'll need to work on the front, which is quite hard work/expensive.

Things from my list:
Front subframe replacement (significant)
Front lexan windshield (significant)
Lighter flywheel (prolly done)
Lighter intake (ITBs/prolly done)
Lighter exhaust manifold (racing ones are already light)
Remove Flip lights, replace with manual construction and led lights
Lightweight alternator or Daihatsu Denso one.
Lighter wheels,
Alloy Struts/dampers

Compared to that the rear is easy (chop chop)
