I've been working on getting my MC28SP back to track worthy condition and thought I'd throw a little bling at it as well.
You can get a really nice set of bolts from T2racing for $152USD or a set of bolts (m6x120) and nuts from ebay for about $100. I've found a place that has GR5 M6x120 studs. With Ti m6 metal lock nuts on either side, price would be about $68/set + shipping from San Diego, USA or local pick up. I need to order enough for 3 sets for this price. Not making any money on this, just the same cost for all. If interested drop me a note.
I don't have weight for the parts but obviously less than stock steel nuts/bolts. If I had to guess, this should save you 0.27s/lap and get you 1.33 points at bike night.
I still have these Ti bits for sale:
