I wish but I couldn't spend $4k+ on custom LEDs with modules. Definitely a major gap in my build!

That means a lot bro. I feel the same way!

Sad no one wanted to buy my baby. Plenty of low ball offers trying to pick me off for a healthy part out profit. Nice try.

A full part out is imminent…I kind of always knew this day would come though. All good!

Sad to see you give it up. You said you were thinking M5 - any consideration to an X5M?

Can't afford a F95 and wouldn't be interested in a F85. I have been looking at used F90s in the $85k price range.

Erik, what do you use to clean your leather?

Hey man, this is what I use. I've always had great results.

[sukhk527]

Good luck with the search for a F90 man, they're beasts. I'll keep my eyes peeled for the part out

[gutierrezb27]

Did you adjust the preload at all? I lowered my x5 29 3/4 in the front and 30 1/4 in rear. Im having a slight problem that when ever i hit a speed bump or slight bump at decent speed. the rear of the car just shoots up, i can literally see the stuff in my trunk flying everywhere. any advice?

[X5Brian]

I'm running bc at 29.75 front with 16k swift, rear 30 with 24k swift. I tighten or firmed up when it jumps like that on bumps. Not saying it's what to do for you but worked in mine. I have a damn smooth ride, just have to control the higher spring rates. No bottom out even on big bumps at high way speeds

No I didn't touch anything before install. I did experience that same bouncy castle ride when I initially started out with max soft dampening. Where did you set your dampening? Sounds like you need to firm it up.

Joined Bimmerpost the first week I took delivery and was off to the races! Every single mod was influenced from what I've seen from others on the forum. I can't stress enough that I literally built this with you over the past 2.5 years. I love you guys. THANK YOU.

My goal with this build was clean and mean. I've never seriously modded a car or truck before so I have to say this was so much fun looking back through all of my experiences. Lots of ups and downs. I could probably say if I had to do each mod again I'd take a different approach with the install. That said I tried to install as much as I could within reason. With each mod I experienced a full spectrum of emotions ranging from joy, satisfaction, headaches, anxiety and even anger. Went through a million clips, lost pieces of random plastic stuff that I have no idea what they were for, and lost screws and torque bits in areas I will never be able to access or retrieve. Just got to move on to the next mod...Trust me it was all FUN!

Parts list with a few comments:

Exterior

• M Performance Carbon Fiber Front Splitter
• M Performance Carbon Fiber Rear Diffuser
• M Performance Carbon Fiber Rear Splitters
• RW Carbon F85 Carbon Fiber Mirrors
• RW Carbon Carbon Fiber Side Skirts
• M Performance Gloss Black Kidney Grill
• M Performance Gloss Black Rear Spoiler
• M50D Open Grill and Trim Conversion - Installed these at the same time as the IND front reflectors. These were the single biggest PITA mods I came across. Honestly not sure how you can do these mods without taking the front bumper off. That was fun...
• IND Gloss Black Roundels and Badges
• IND Painted Reflectors
• Autotecknic Carbon Fiber Fender Inserts
• Autotecknic Carbon Fiber F85 Grill
• Thule Aero Rack
• XPEL Prime XR Plus 20% Front Tint

Interior

• Alcantara and Perforated Leather Steering Wheel w/ F85 M Performance Carbon Fiber Trim - 2nd wheel I've ordered from Coby - Couldn't recommend them enough!
• F85 Napa Black Knee Pads - Another PITA mod.
• M Performance Carbon Fiber / Alcantara Trim
• M Performance Carbon Fiber Shifter
• M Performance Carbon Fiber Console
• M Performance Stainless Steel Pedals
• M Performance Illuminated Door Sills
• IND Polar Blue Start Button
• M LED Puddle Lights

Suspension

• BC Racing Coilovers - Good all around coilover from BC Racing. If you want a modest uptick in performance while lowering your truck at a good price, these are for you. Note they only make a kit to replace the standard 4 steel spring option. Take your time dialing these in - PATIENCE required.
• KMAC front adjustable bushings - Big fan of camber kits - Along with the SPC rear kit, these are the only ones available for our trucks. I was able to bring negative camber to exactly -1.0 on all 4 corners with this kit. I couldn't handle the tucked look so this was more of a cosmetic mod even though you will see a cost savings on tire life.
• SPC Industries adjustable rear control arms - See above.

Performance Upgrades

• M Performance Brake Kit with F85 Rotors - #1 favorite mod to date - The stock 50i setup is criminally unacceptable.
• Brembo Rear Big Brake Kit (Porsche Retrofit) - BMW needs to include 4 pot rear calipers on all of their performance vehicles. C'mon!
• Dinan Stage 1 Tune - I posted recently about my first Dynojet pulls registering 423 awhp / 478 awtq here.
• Dinan Cold Air Intake - Pretty carbon fiber housing that sounds mean but not worth the money - the modest performance gains don't justify the cost.
• SuperSprint Race Muffler w/ Gloss Black Powdercoat Tips - Beautiful Italian engineering that brought my truck to the next level.
• NGK Laser Iridium Plugs - Gapped at 0.60mm

Current Wheels

• BC Forged HCA162S - 22x10.5+30 / 11.5+16 (Matte Black Center/Gloss Black Lip/Black Exposed Hardware) w/ Atturo AZ850s. Experimented with my offsets relative to my first set of BC Forged 22s, going slightly more aggressive. I think these are the perfect offsets for those who are lowered on coilovers. Favorite wheels to date and only added an hour of detailing time with a 2 piece exposed hardware wheel! Give Atturo a shot - quite the underrated tire brand. Some additional photos here.
• 611M Winter Set - Gloss Black Powdercoat w/ IND custom black center caps. Running with 15mm spacers on all 4 corners.

Previous Wheels in Order

• 469M - Brief stint with original set off the lot.
• 467M (Winter set) - Paid full price for this winter set from the dealer at time of purchase. Still my worst buy to date but I was clueless at the time.
• 612M - Gloss Black - These were (and still are) my favorite OEM wheel.
• BC Forged RZ21 - 22+10.5+32 / 11.5+19 in Gloss Brushed Dark Black - Absolutely loved these wheels. First dive into a forged wheel and couldn't have been happier. Decided I wanted a satin black wheel so moved on.

AND I'M DONE!!!

Man you've got me wanting to spend some money on the X5. Looks amazing

I Actually put it on max soft.

Yes that's your issue. Adjust to mid dampening and you'll be all set

I thought the same, but even with mid softening I have the same issue on certain bumps at highway speeds. The shit in my trunk literally hoists in the air. I wish I would have gone with stiffer spring rates on my BC coilovers. To note I'm on 22" wheels with rubber band tires do to x-drive and transfer case.

[gutierrezb27]

im on 20 inch wheels. Im going to adjust the dampening. and see if it changes.

[X5Brian]

I'm running 16k front and 24k rear, somewhere around 20-22 clicks firm. Rides good, handles amazing. Zero bottom out in rear @ 29.75 GTF.
Def recommend swift springs and much much stiffer than bc suggests. I have some 16k and 20k swifts if anyone wants to step up higher— rear springs. Mine are also for extra low kit. I think they are 8" in height

[classic_erik]

I'm at 12 clicks up from max soft and don't have a bouncing issue.

So the 20K rear swifts weren't stiff enough for you? I'm on the standard recommended BC springs. Any clue what those spring rates are? I can't remember.
