For those who wanted just upgrade instead of buying the new 2018 kit... here are the part numbers:
25867: Suspension holder: 450 JPY (New plastic suspension mount set to attach the CFRP Rear Bulk Plate)
25866: CFRP Rear Bulk Plate: 700 JPY
25865: Alum. Rear Bulk head: 1400 JPY (this attached to rear turnbuckle and to the chassis and sandwiched by the 2 rear plastic support beams)
25864: New CFRP Rear upper mount: 1900 JPY
25863: New CFRP Front upper mount: 1900 JPY
25862: Roll Bar: 980 JPY ( x 2 - you need 2 sets of these for front and rear)
25861: New Alum Knuckle for DCJ - 2600 JPY (you need these to be used for the new Double Cardin Joints as the previous Knuckle will not work)
25860: New Double Cardin Joints - 4900 JPY (Finally! DCJ!!)
Total MSRP: 15,810 JPY ~ 144 USD (OUCH!! OUCH!!! that's like $100 off for a new kit!)
Don't know if there are any places that might be cheaper? As I know that these parts are selling in Japan right now - but in Hong Kong, it is not available yet as of today (including RxMART)
