Genuine Top Secret Carbon Fiber Rear Diffuser, made in Japan at Top Secret. Price does not include the optional vortex generators and mid-air diverters.
What are vortex generators and mid-air diverters? See our pics here with the yellow arrows. The outer "curly-Q" pieces are the vortex generators and the middle slots are the mid-air diverters. Knock-off brands of Top Secret offer these items separately - Top Secret Japan offers them only as a full set. So either get only the rear diffuser or get it all, those are your choices.
These are made to order and take about 5 months to arrive to us here in the USA. The price here includes all of the costs to get it from Japan to our warehouse here in the USA (shipping from Japan, import fees, duties & taxes). The only additional cost to you is shipping from our USA warehouse to you. Shipping cost is determined based on your address, if you wish to know shipping cost before you order please contact us first. This is too large to go UPS/FedEx, it has to ship truck freight (a.k.a. LTL). Expect shipping cost to be $250-325 as a general range.
