Arkym E90 Diffuser

Chowster · 05-21-2013, 01:52 AM

Well, there have been many threads about E90 diffusers and the lack of choices for our sedans. I decided to go ahead with the Arkym piece without seeing very many good pics of exactly how it looked. Why Arkym? Design - I wanted a full length piece, not just a center piece like the Challenge design. And price! I purchased from PYSpeed, without much issue.

Install? Easy, even for a novice like me. I used 3M tape on the top edge and sides, and 4 bolts underneath. No betalink used. I love my 3M tape - I'll be using it on my future CF performance spoiler.

Fitment? Pretty good, IMO. Probably 8.5/10. The curvature of the top edge of the diffuser does not perfectly match the curvature of the bumper, mainly near the ends of the honeycomb section. However, my 3M tape was strong enough to pull the diffuser to the bumper and I didn't end up with any gaps. I installed this in the dead of Canadian winter, so I didn't have the advantage of warmer malleable parts.

My exhaust? Dinan rear. It wasn't hot, or even warm, so the tips are recessed into the diffuser. When the engine and exhaust system is hot, the tips protrude out beyond the diffuser very slightly. I wish I had an exhaust with adjustable tips like Akra or something with similar adjustability. My full list of mods can be seen in my signature below.

Here are the elusive photos that many people have been searching for! iPhone quality, brightened up a bit to show the diffuser more. I can try to take other requested angles or views if required.

Thanks Gene! I thought the same... goes nicely with the splitters and mirror caps. And thus the pending spoiler order and install! Just trying to decide on a "regular" CF vs. an iND CRT-style spoiler with a SSII accent line. What do you think?

Looks good. But the exhaust tips need to be out more.
