INSTALL DOES NOT REQUIRE REAR BUMPER REMOVAL




Details

Experience Flow-Lock rear diffuser for your i30N Fastback, sharing the same durability and technology as our renowned WRX, Golf GTI & MK3 Focus RS line up which is trusted by car enthusiasts worldwide. The rear valance and diffuser fins will clear the i30N dual exhaust tips with ease, and rear bumper removal is not necessary for installation of the diffuser. 10 year warranty applies for the rear valance (excludes ABS fins).

The Flow-Lock interlocking system allows for the final assembly of the diffuser fins without tools or fasteners. A simple push and click and the kit is assembled and ready for installation - this means zero exposed hardware giving you the cleanest look for your i30N Fastback rear. Front lip splitter is also available for the i30N Fastback.

No more L-brackets, no additional exposed hardware and no double-sided tape, experience the Flow-Lock difference today!
 

Pre-assembled rear diffuser Aerospacers are bolted down perpendicularly to create a brace that reinforces the rear valance and evenly spreads the load from impacts across the surface. It also allows the diffuser to follow the body kit contour to keep it flat and level.

Valance is installed to the car through bolts and nuts while the Flow-Lock diffuser fins simply click into the valance (once locked into the valance it is secure). It is also possible to install when your car is on the ground.

  • i30N Fastback PD Flow-Lock rear diffuser
  • 2 Flow Designs stickers
  • Fitting kit

Super big
Color: Light Grey, Size: 36
Bought 4 pairs of these shorts and had to send all four pairs back. They run very big, in the waist and overall. They are super long. My son is 5'10" and he said they were way longer than he wanted them. They appear to be good quality, heavy material jean shorts. I would recommend sizing down if this is the look you're going for. And they're a little pricey.

Shorts
Color: Green, Size: 40
With exception of the seeming low quality zippers and fasteners, the shorts are nice in fit and style.
