#ModifiedBmw

Is it a crime or just a really good idea? One thing is for sure, this SEMA Show car is an excellently executed project.

When building and customizing a car, owners often find inspiration from a race car or another higher-performance version. Other times inspiration can come from an existing, but very different vehicle, which is the case in this awesome BMW M5 build.

One of the most impressive vehicles at the SEMA Show is a widebody BMW M3. Built by the carbon fiber experts at Vorsteiner, the kit is actually called the GTRS3 M3 and adds significant width to the body of the Bimmer.

This is most certainly a surprise from Mansory. After making huge splashes with their customized Aston Martin DB9, Bugatti and Maserati Gran Turismo, the last thing we expected to see from the wild German exotic car tuner was a BMW X5 M. Even more shocking is that it’s not a 9-inch widebody with 24-inch gold wheels, matte-orange paint and more carbon fiber than an Airbus A350.

And along with that 725-hp is an astonishing 656 ft-lbs of torque, an increase of close to 155 ft-lbs from factory spec. The aerodynamic package is similar to what we’ve seen before, widening the stance of BMW’s X5 M even more and is available for $16,300. And you’ll need a widebody if you’re going to go and sport massive 23×11-inch wheels in the front with a staggered 23×12-inch pair in the rear. Pack those babies up with 315/25/23 rubber and you’ve got more than enough at your disposal to handle 725-hp. The SUV also sports a mild drop of 1.1-inch.

Oh AC Schnitzer, you’re actually late to the party this time around! BMW‘s new 2011 5-Series has already been overhauled by quite a few tuners including 3D Design and Lumma Design and now the brand synonymous with BMW customization over the last few decades has embraced BMW’s new sedan.

Little-known but well-respected BMW-tuner Hartge has done a surprisingly good job at styling up BMW‘s X1 and has even thrown some horsepower gains to the mix.

The X1 18d motor can receive a 36-hp boost (to 179-hp) with 258 ft-lbs of torque to play with. The xDrive20d will get a 32-hp boost with 306 ft-lbs of torque. And available for all X1 models is a new exhaust to improve the sporty sound of the smallest BMW crossover.

Now for the styling goods, Hartge offers a conservative 1.2-inch drop for the X1, which makes outfitting the SUV with a set of wheels that much more appealing. On this particular demo car, Hartge opted for their Classic 2 wheel in a 20×9/20×10 setup. The wheels are wrapped with 245/30/20 tires in the front and 295/25/20 tires in the rear with Hartge recommending rubber from Pirelli or Michelin.

And of course you can get your run-of-the-mill interior upgrades from steering wheel to pedals to hand-brake.

The only pricing they announced is $2,400 for the 20d power kit – but that U.S. pricing is pretty much irrelevant as you can be sure BMW won’t offer a diesel X1 when the car finally does go on sale here.

Official press release available after the break.

Back in May, we discovered Onyx Concept based out of Dublin, Ireland. They had done an interesting package for the Land Rover that we had mixed opinions about. But we noticed on their website that they also tinker with a plethora of other makes and manufacturers, but for the most part preferred to stick with SUVs. Whether SUVs are just too boring, or Onyx Concept realized there’s some money to be had with sporty coupes, the tuning house has decided to release a package for BMW‘s ever-popular E92 M3.

Lumma Design is slowly becoming one of our favorite new tuners, having checked out their 760Li project and Top Car built X6 M. Once again, Lumma has teamed up with their Russian tuner Top Car to show off what the new BMW 5-Series is fully capable of.

We don’t have our hands on the official press release from Hamann yet, but it looks like they’ve released a fine collection of goods for the BMW 7-Series. And as with all Hamann tuning packages, we see no big surprises other than a variation of front ends available to complement the rest of their standard body upgrades.

We’ve seen so many variants of BMW‘s X6 by now that we’re not even sure which one is our favorite anymore. But it’s clear that the aftermarket has really embraced BMW’s performance SUV despite its odd identity crisis. This time it’s AC Schnitzer with a widebody X6. Interestingly AC Schnitzer hasn’t officially released this kit yet, with the vehicle making its first appearance at the National BMW Festival out in the United Kingdom.

Rather than wait for his parents to buy him a car for his 18th birthday, Denislav Shishev from Bulgaria took matters into his own hands by taking a wrecked BMW Z3 M coupe and transforming it into the above vehicle with help from his friends.

We’ll be the first ones to say that the current BMW Z4 is by far the sportiest and nicest looking Z4 BMW has produced. Long time BMW tuner Hartge has entered the fray tuning the inside, outside and performance of the new Z4.

At the top of the list is an ECU upgrade for the turbocharged roadster, pushing horsepower to 350-hp from the factory 306-hp. It also eliminates the speed limiter and helps blast the Z4 to a 4.7 second 0-62 mph time. It’s currently available for $2,600 and Hartge promises minimal change in your MPG. How thoughtful of them.

On the outside is Hartge’s Classic 3 wheel, a refreshed version of their popular Hartge Classic wheel. A staggered setup has been bolted on with 20×9-inch in the front and 20×10-inch in the rear. Suspension upgrades lower the Z4 a subtle .8-inch in the front while the rear benefits with a real minor .4-inch lowering.

Familiar styling comes with Hartge’s front lip and rear spoiler along with Hartge emblems and decals. We’ve never been a huge fan of Hartge’s exterior body kits but we think this one is a killer addition to the already aggressive Z4.

And for those looking for a little luxury, a special wind deflector is available made of single-layer safety glass. Other interior upgrades are pretty standard with pedals, steering wheel and floor mats.

Official press release available after the break.

Shaston, a Switzerland-based international distributor of Windows Mobile devices, just sent us these photos of a BMW 760Li Individual, modified with parts from well-known BMW-tuner Lumma. They didn’t give us a ton of details, but thankfully we’re equipped with a pair of eyeballs to make some observations of our own.

The old saying “If it’s not broken, don’t fix it,” rings true with Hamann. Over the last decade and change, we’ve been able to almost predict how Hamann’s styling packages would look on new BMW chassis. While it may not be a bad thing, it’s worth noting that there isn’t anything groundbreaking or original (in the Hamann sense) with their newest product addition.
