Dinan 330i joy ride video:
A few of us visited Avus Autosport to view their facility and showcase of Dinan modified BMWs including their E90 330i equipped with Dinan suspension, BBK, ram-air intake, high-flow throttle body, and free-flow exhaust system.
I would like to thank Avus Autosport, and Dinan representatives Jeff Lutjens, and Izzie for their hospitality. Before we left, Jeff gave me a big thumbs up thrill ride in the E90. I will post a video when time permits.
The Stage 1 Suspension system consisted of Dinan Performance Springs, Koni Struts, Koni rear shocks and bumpstocks. I was impressed by the suspension, which was very compliant and forgiving when going over bumps while cornering at high speeds. Body roll was minimal. The ride was noticeably more rigid, presumably in part from the stiffer dampening.
I was quite impressed with the beefy exhaust system, which had a very nice throaty and aggressive, but not obtrusive sound. The muffler and mandrel bent piping were quite substantial if not hefty. I could not squeeze under the car to take a good look, but the system seems to be complete cat-back with what appears to be 3" piping. I liked the exhaust note. It was not annoyingly loud, nor did it have that typical deep, sickly boat sound. Take the stock 330i exhaust, hook it up to a stereo system, turn on the bass, treble and midrange especially, and you'll get a good idea of what the exhaust sounds like.
