flipo - you're in nice levels in weight. espec with roll cage! what steel bits have you left except car frame, or is every shell part some kind of Xfiber stuff? What about roof?
Proper roll cage would give some more freedom to get rid of unnecessary metal panels. ,)

al body panels are glasfibre including roofpanel ,I cut off everything that is not needed on a racecar ,the car also has a manual steering rack and no abs,the rolcage is crmo steel ,the ducts for the intercooler and oil coolers are carbon fiber .

I'm thinking about making a second spare bodyshell and i think I can save some more weight ,maybe 1000kg is achievable
