   2004 Just before I roll it to woods... :(


  • We cant use engine cover (scoop), because of Finnish rally regulations.
  • Also mudguards must be steel, except areas you can see. 
  • Now we attached also rear brake air inducts, and rear bumper cover. I will put pics to see of them.
  • I have had it since 1996, all of it is made by me or my friends. 
  • It took one year to weld it together, and two m2 steel! 
  • Its been made of normal 2d body. I have also one 2d body, that we are going to build for a spare. 
  • Eventually this will roll over in so fast speed that there is nothing done except new body !
