SBC is only like .1 pounds heavier than regular RPF1. 17x10 SBC is 17lbs even, compared to 16.8 or 16.9 lbs for the regular version.

I put on my front coilovers with the ebay camber plates. Works out much better than with the Tein camber plates, although I ended up using the higher quality Tein hardware. New front wheels/tires are on also, but I ended up using a 5mm spacer for clearance (I can probably add some negative camber and get away with not using a spacer). Just need to do a few things to it in the morning and then I should be headed over to Tampa in the afternoon for an alignment.
