Saw the Dinan site and they are running a 15% discount right now. Contacted a local Dinan sponsored shop in Northern VA and got an OTD quote for the following:
1) Stage 4 upgrade
2) Intercooler upgrade
3) Exhaust + fabrication to utilize stock tips
4) Suspension upgrade
all installed during 2days for $13,022 (this includes the 15% off from Dinan). Ultimate question, especially to those with any of the upgrades...Is it a good deal and is it worth it? I would also look at paying for some new wheels/tires as well (also an added expense of $4k).
I have never had the pleasure of having Dinan upgrades and have always known that they are the "Gold" standard of aftermarket parts for BMW. I am very on edge to get these upgrades.
