First off, I'm going to admit I'm not the most helpful person when it comes to keeping track of the weights. Partly because I don't have an accurate scale but mostly I'm too excited to get the new parts on I forget to weigh them first. Luckily I still have all the shipping boxes and shipping weights so I can do the math. Anyhoo...
Nothing from any vendors? Bummer...
Since I am also very curious about shaving off some weight, especially the front I'll put this out there: the stock strut brace seems pretty light but I'd be curious to know how much a $2400
titanium one would be.
If you want an 11 lb exhaust (y-pipe ans single exit) you could do the titanium amuse r1000. Only $4k
I'm curious if you did a trade between narrow lighter wheels and wider one with more grip. I personally just went with the widest then tried to minimize the weight.
How about lightweight lug nuts? They'll help the unsprung mass but won't do much for rolling resistance. Rays short type are 17g each. 0.75 lbs for all 20 so ~2.25 loss compared to stock listed in RCZ's thread
