the lightened steel outdrives are good, but they weigh a ton.they make the car heavier and add to rotating mass,good point is that there bomb proof i think
well the ft anodized motor mount and ft motor clamp thing,what a rip i bought them thinking they woud be of a higher grade alumunium but there not there the same cast crap anodised blue instead of black.i was foolish enough to buy them.
and weigh them, the black motor mount was 0.1 gram lighter than the blue, but you could put this down to porosity in the aluminium casting (when cast)
the standard hinge pins are abit soft you could get some ft hardened ones which are great or 3 racing titanium ones... harder than standard but still bend!
lunsford do some too, but i havent tryed them!
p dub bumper is a must!! saved me some wishbones mine has!!! lol
i quite like rpm ball cups too as they are a much firmer fit
