Parto-D is a japanese brand of lip kit. Search TC Sportline, Type F1 kit, and many more. Extremedimensions.com has them I believe . Parto-D lip sticks out more at the top and has a different curvature, and actually has vents in the side skirts IIRC. Just more little tid bits of info.
The pics you are posting as Parto-D, are actually TC sportline. Parto-D only fits on first gen JDM bumpers and are not in the US.
Heres some pics of an authentic JDM Parto-D kit:
Notice the difference in curvature on the lip between that and MrSparkles TC sportline? Also, the Parto-D has some vents in the front of the side skirts that you can see in teh second pic. Then of course the rear lip with the plate. Im just trying to clear up some misnomenclature on this. The kit you're really talking about when you say Parto-D, is really TC sportline or "F-1" kit.
