Just to please me, have you actually weighed these 12 bolts to find out how much they weigh? And then how much you would save by using aluminium or titanium bolts?The gain might be insignificant compared to just having a big sh!t before you race.
Just use steel bolts and look in your yellow pages for Engineering factors. There are loads of these sorts of places dotted around the country (ie All thread) and they will be a lot cheeper than the prices you have put up so far. Just a thought but have you looked at your engine mounts as I managed to take over half a kilo of material out of a friends kart engine mount recently (and could have taken more out if wanted). Admittedly I had access to a milling machine at the time but they dont need the spars that connect the front to the rear of the mount and that can be removed with a hacksaw lol. Bits like this are far more likely to lose weight than replaing bolts with ali versions adn there are plenty of other plaes weight can be safely removed from that will get you some nice added lightness.
But if Andres drops a log, AND replaces the bolts with lightweight items, hell be faster than a cat, with a red hot poker up its arse!Thom
stick £15 in the forum charity pot and I'll send you 15 off M8 x 25 x1.25 steel bolts.......
