well.. a company like APC might make a spoiler thats functional, but say if you bought a spoiler from a company like cwest they actually wind tunnel test it, and take it to a track and actually test it out to see if it improves their lap time etc. They engineer their spoilers to be effective. Like i said.. the cheap spoilers require a really steep angle of attack and on top of that they flex. That's why i want a spoiler with the supports at the sides and not in the middle. I want least possible amount of drag and maximum amount of downforce. Also someone else mentioned.. why not get an aluminum spoiler.. for the same reason. Aluminum spoilers are flat and u just angle them for downforce. JDM carbon fiber spoilers work off the concept of an upside down airplane wing airfoil.
SmithSR: I live in the bay area (in california). My sponsors can get me hookups on things they have in stock over here, but for special orders directly out of japan, they basically have to pay the same thing i do to get them, and on top of that you have to wait a really long period of time, shipping is very costly as well. You imagine it costs like 100 bucks just to ship over a pair of headlights, a spoiler would cost an arm and a leg. I spend a lot of money on my car, but i shop smart. Putting my car together could have costed me twice as much. For instance I got my HKS SSQV off ebay brand new for 100 bucks. Can't beat that
