650ix Gran Coupe Upgrades

[mdrobc13]

So after looking around a lot for a rear diffuser upgrade for my 2014 650ix GC; I finally found suitable option. Sourced the 3d CF rear diffuser from the guys at IND (thanks Nate) and then also was able to upgrade the rotors to R1 Concept cross drilled ones. Added new emblems redone in gloss black and an Eisenmann Race Exhaust in gloss black. Inside [so to speak] have done a Dinan Stage 3 Performance ECU and Intercoolers to increase the performance to a proper level and add a proper exhaust note.

So far am improved with performance and fit and finish of the new parts and no issues. Now vehicle sounds like I expect a BMW to do and drives much better as well. Sporty but not too harsh a ride. Since its an Xi will have to wait for a set of springs to lower and tighten the suspension a bit [in such a big car] but I coming from a 2012 F10 550i; its a comparable ride albeit slightly better. Enjoy.

PS..thanks to Nate@IND and also Jeremy and the guys at Matrix Integrated in Portland, Or for doing all the shop work and coordination with the body parts painting/fitment. Great job once again guys.

It looks like you spent about 11k plus labor and you're not done yet. Why not just get the M6?

Very beautiful monster ,great mod , I specially liked ur exhaust with the black tip , I will see if it fit the 640 cause I already bought the M6 rear diffuser and I need to do something to transform it to quad tip ,
But I think u need to upgrade ur wheel or lower the car ..
Good luck

I bought the 650i vs M6 due to the xi option! Living in Western Canada it's a must. Had a F10 M5 and it's hard having a 120k car sitting for half the year!!

Yeah maybe IF I did spend $11k on everything then maybe but I got the GC at about a $14k discount off MSRP (end of model year discount and BMW $$ thrown in) in Sept and good deals with my tuning shop and suppliers. In all I spent about $9k parts and install less $3k back from parts off my old 550i which I was able to resale to new owners and then use that $$ back towards my upgrades.

So using those savings I am still about $20-30k under the initial outlay of an M6 GC at least. Also AWD was important to me otherwise I would have just kept my 550i w/Dinan.

Had an e92 M3 w/winter tires (Blizzaks) and was okay in inclement weather and snow but sometimes really it was too much power/setup for bad weather conditions where AWD would have easily or more confidently gotten you from A to B.

So..Concur..had the same problem with a Dinan modded F10 550i! Opportunity for the upgrade and AWD made it easy v M6 and tons of power but weather/roads limited

Those are my winter wheels for now. 19" OEM A/S Pilot Sports. 20" wheels go back on in Spring. Will try to use old 550i wheels but may upgrade due to color/design. Waiting for a proper sport spring set as Dinan and H&R have nothing yet for the AWD XI according to my shop.

Not too many spoiler options for the 6 series GC. This one was a CF one for the 6 series. Its not that big in person but can look so..was worried about the optics myself but it has grown on me.
