An old thread raises from the dead.
The Dinan software was removed by dealership request after 7 days, as it caused rough running when the engine wasn’t fully warmed up and Red Cog emission’s faults (engine backfires.) From conversations with Darren_Dallas and others who’ve tried E60 M 3rd party software, the return for dollar spent is low. Wait for lower priced, Shark Injector type products, where you can download and install software yourself.
After eight months, I’m pleased with the Dinan suspension, although I just learned all four springs will need to be replaced due to a design defect.
Problem with Dinan springs?
The car corners and handles much more neutrally. After a local fun run, another M5 driver with factory suspension, told me he couldn’t keep up in the twisty sections. The gap between tires and wheel wells is small and even, with adequate room for wider wheels/tires. Ride comfort is slightly degraded, Comfort mode now feels like pre-install Normal mode. Only negative is the need to stop short when parking in spaces with concrete tire stop, lowered body will rub otherwise.
If you’re thinking about the Dinan Stage II suspension, either wait for the updated springs (4-6 months) or purchase Dinan roll bars and another brand of spring. If you're running wider tires and wheels wait for the Dinan parts.
For
Qs06M5 and other D/FW M owners, we have an informal meet each Saturday morning at the Starbucks in Plano at Park Blvd and N. Dallas Tollway.
