Haha, you look like your pretty set anyways. From memory, BC coilovers are the same as the ones Pedders use/sell. Not saying they're bad, but they're nothing spectacular. A set of Tein Street Basics would set you back sub 1k and perform similarly but with fewer adjustments (if you wanted adjustments), or Tein Street Advanced if you want something a bit more comfy (especially if you're going up in rim size, you get a firmer ride).

As for brakes, RDA is fine for road use. DBA are better quality, but you pay the premium for them, and if you use them on the road then you really don't need to pay the extra. Cross Drilled and Slotted, either is fine. The reason I would recommend against Cross Drilled is because it makes your rotors more prone to cracking. At least slotted have a more feasible use (better ventilation and helps clean dust for more consistent braking). Again, depends on what you intended to do with it. For day to day driving, RDA is fine. DBA T2 are pretty much overkill for the road as they are, and your paying a premium if you go XS (drilled and slotted). Up to you how much money you want to spend (do note that in DBA online catelogue, they recommend their Slotted range S for light trackwork, but none of their XS (cross drilled and slotted) are listed). As for pads, if you want performance pads, I would recommend QFM HPX. They're like Bendix Ultimates but with less dust. There's still, all pads will make dust, but you don't need a weekly wash.
