  1. Jet Black E90 M3 on F8X 513M Wheels

    This elegant M3 sedan is modified where it counts. Replacing the stock wheels are a set of Style 513M wheels from an F80 M3, which weigh only 19lbs for the fronts and 21lbs for the rears. Behind the 18" wheels are AP Racing big brakes mounted up to a set of KW V3 coilovers for optimal braking and handling performance. Inside, an M Performance Alcantara steering wheel and Pedal Haus aluminum pedals provide both a sportier look and feel every time the car is driven. The body has been kept simple, with just a Challenge carbon fiber race trunk, iND painted reflectors and BMW gloss black kidney grilles adorning the exterior. Enjoy.

  2. sillieidiot's Alpine White E46 330Ci

    E46Fanatics member sillieidiot has been bringing his Alpine White 330Ci to us for the past 5 years now. During that time, we've seen this E46 change, grow and evolve into the car that it is today. Recently he stopped by for an alignment service, so it was the perfect opportunity for us to grab some new photos. Featuring a lengthy list of modifications including things like a carbon fiber roof, carbon fiber hood, carbon fiber trunk, AST coilovers, APEX ARX-8s and OEM M3 exterior components, this highly customized 330Ci has successfully maintained a clean, yet head-turning style. Take a look below at the photos and the full list of modifications to get some appreciation of all the work that went into building this car. If you want to dive even deeper, then check out silieidiot's very own build thread on E46Fanataics. Enjoy!

  3. Alpine White M3 on Hyper Blue TE37SLs

    While the Volk TE37SLs are one of the most popular wheel choices we see on M3s, these are probably the first we've seen in this Hyper Blue finish. And, wow, they really do pop on this Alpine White E92! Wanting a more aggressive offset from these 19" Volks, this customer had us install 10mm Macht Schnell wheel spacers in both the front and rear. While we were at it, we also went ahead and installed a Macht Schnell 75mm stud conversion paired with neochrome Project Kics R40 lug nuts. Underneath the car we swapped out the restrictive stock exhaust for a full stainless steel system, comprised of an Eisenmann Race muffler mated to a Challenge Street X-Pipe. For additional power gains, this 6SPD M3 has been fitted with a Macht Schnell Stage 2 Intake under its hood. Like many cars that come through here, an iND painted cosmetic package gives the finishing touches to this clean, eye-catching M3. Enjoy.

  4. Dakar Yellow Liberty Walk E92 M3

    If you've ever taken a good look around the M3Post forums, then you have almost certainly come across Powerbeast's Dakar Yellow M3s. Similar to his previous E90 M3, this E92 (which was prominently displayed at Bimmerfest this year) was built with absolutely no expense spared. If the long, high-end modification list below doesn't excite you, then the photos of this wild E92 just might. Enjoy!

  5. Yas Marina Blue F10 M5 by iND

    Whenever our friends from iND pay us a visit, we just know we're in for a real treat. The day before Bimmerfest, the guys from Chicago dropped by our facility with this absolutely stunning Yas Marina Blue F10 M5. We've actually had this M5 at our shop last year, but you definitely wouldn't recognize it now. Instead of a hardcore track-prepped car that featured racing seats and a roll bar, this F10 is now focused on the street. Cosmetic changes include a Yas Marina Blue paint job, two-tone pin striping, a full LCI conversion, BBS LM wheels, painted OEM brake calipers and a black thermal coated Eisenmann exhaust system. The 3D Design carbon fiber side skirts, rear diffuser and front lip spoiler remain unchanged. Inside you'll find the stock interior decorated with an Alcantara steering wheel, carbon fiber trim (complete with a Yas Marina track outline), billet aluminum pedals and custom colored floor mats. This M5 also gained some ponies since the last time we saw it, as it is now fitted with an AMS turbo upgrade and AMS catless downpipes. This M5 was the center piece of iND's Bimmerfest booth this year, but in case you missed it then take a break and check out these photos. Enjoy.

  6. Dakar Yellow M3 Sedan on Volk TE37 Wheels

    As far as M3s go, Dakar Yellow sedans are exceedingly rare. This E90 features a set of matte titanium gray 18" Volk TE37 wheels and is lowered on Ohlins coilovers. The combination of these ultra lightweight wheels mated to the high-end dual flow valve suspension gives this M3 both sharper handling and looks. BMW's carbon fiber Performance spoiler sits neatly on the trunk while the Challenge carbon fiber roof panel replaces the OEM sunroof. With its clean modifications, unique color and four door body style, this M3 is sure to get looks everywhere it goes.

  7. A Clean Monte Carlo Blue F10 M5

    Painted in beautiful Monte Carlo Blue, this 2013 M5 is dialed in for a clean OEM+ style. The first order of business for this F10 was to eliminate all the chrome from the exterior; matte black OEM wheels along with IND's gloss black painted kidney grilles & side marker gills did the trick. Surrounded by Challenge's carbon fiber diffuser, the Eisenmann race exhaust system features large 102mm black tips and brings a whole new level of sound to this twin turbo V8 beast. For a lower and wider stance, we installed a set of H&R sport lowering springs in conjunction Macht Schnell wheel spacers. BMW's Performance carbon fiber rear spoiler, complete with a Monte Carlo Blue pinstripe, gives the finishing touches on this car.

  8. Gruppe M Intake Installed on IND's F10 M5

    Gruppe M produces high-quality, hand-made carbon fiber intake systems, which not only boost a BMW's performance, but also add some carbon fiber flair under the hood. The factory ductwork and airboxes are replaced with heat-shielding carbon fiber with enhanced inlets to capture the maximum amount of air. Lower intake air temperatures carry higher concentrations of oxygen, allowing for more energetic explosions and producing more horsepower and torque. Of course, reliability is never sacrificed -- high-efficiency, high-flow K&N air filter materials prevent contaminants from interfering with proper engine function.This high performance ram air intake was the perfect choice for IND's F10 M5.

  9. Carbon Fiber Lip & Spoiler Added to Takata Green TE37SL M3

    After getting his Takata Green TE37SLs installed, this customer turned his attention to the exterior of his M3. The first order of business was to give this E92 the properly aggressive stance that everyone wants; a set of B&G lowering springs did just the trick. To further accentuate the lowered stance as well as match the OEM carbon fiber roof, a Challenge carbon fiber front lip spoiler and a BMW Performance carbon fiber trunk spoiler were installed. These two components give this M3 a more race-car-like profile. Last, but certainly not least, is the rare Euro Mevius front big brake kit, which will help improve this M3's lap times at the track.

  10. IND's F10 M5 Visits European Auto Source

    IND's latest masterpiece is this F10 M5, which was revealed at the SEMA show in Las Vegas this year. Having a close relationship with IND, we arranged to borrow this beautiful car and show it some eas hospitality. In the next week we'll throw it on the lift to get some new parts installed and strap it to the dyno to benchmark its performance. Given the opportunity of borrowing such a unique car, it was only natural for us to take some photos of it enjoying the California sun.
