Sorry mate)) i saw this car and want to add smth))
If smb give me such car and said "must drive 1000"
The 1 think i started to do was finding out resisting place in this car...
If we can't increase HP we can decrease HP loose in resistent part
1) Tires.. have to use maximum hard tires and preesure or w/o air tires!!
2) Brake caliper and disk there some power lose.... sure you can put some oil to disc))))))) i did it if iwas in you plase))
3) Put holes in everithing that you can)))) I'ts realy help decrease mass..
(steering rock,final drive, driver seat , sreerin wheel
must be full of holes
4) if it possible do mass distribution from left and right like 50% 50%
Use very young and little-mass driver)))
I belive you win this competition
Best regares!! CU
