Dinan is a bit heavy on the price side in terms of parts and labor, BUT I will admit that they've got some great engineered products.

The DINAN supension is tuned quite well for the M Coupe/Roadster and Dinan does a good job increasing suspension performance and still maintaining balance (in that sense, adjustability isn't really needed since the springs/shocks/struts have already been optimally tuned).

DINAN suspension won't lower your vehicle by much. Probably half an inch. So, as far as looks, you will be hard pressed to tell there is a DINAN supension on an M Coupe/Roadster. However, the performance is significantly increased when you're in the car.

Neiman Marcus? Probably. A bit on the pricey side? I'd have to agree. BUT, they are also very well engineered products.

Would I purchase from DINAN? Depends on the parts and what's competively out there. In the Superchager department, I'd swing heavily in DINAN's neighborhood. Exhaust, etc. I'd probably go elsewhere.

In the end, do what you feel is right for you. You can listen to other people's comments/suggestions, but in the end, you're the one who lives with it.

Personally, I think you'll do quite well with the DINAN suspension.

Good luck and let us know how you do on the autocross with the new suspension!
