Oh, look. There's another German aftermarket company that has prepared a program for the BMW 4 Series->ke3834. At this rate, we're probably going to see enough aftermarket programs to fill up an entire catalog. Not that it's a problem, given the 4 Series is nothing short of awesome. This is exactly why so many tuning->ke1987 firms are jumping all over it. And now we have the German aftermarket company Best-Tuning, which is known for its works on Bavaria's finest.

Since its founding in 1997, Best-Tuning has created a laundry list of tuning kits for cars and motorcycles. Its latest work on the 4 Series follows up on that tradition, even though the lack of any aesthetic upgrades won't win it any style points from us.But who thinks the 4 Series lacks so badly that it actually needs aesthetic enhancements?

Even without the styling upgrades, this program is far from a dud. Actually, it's got some nice qualities to it, although not to the extent of what other aftermarket firms have developed for BMW's->ke178 newest eye candy.

Best-Tuning did do some serious work improving the 4 Series' performance capabilities, including a mild engine tune and some chassis upgrades.

BMW 435IX By Best-Tuning in detail

Best-Tuning enlisted the help of fellow tuner Schmidt Revolution to install a sexy set of wheels on the BMW 4 Series. For this program, Best-Tuning opted for 20-inch, Gambit-type wheels wrapped around 235/30R20 tires on the front and 275/25R20 tires out back. Separate of the total cost, this new set of wheels carries a price tag of €2,600, which is about $3,500 as of 8/4/2014.

The German tuner also installed KW coilovers on the 4 Series, a result of its partnership with KW-Suspension. There's an offer to install different coilover kits on the 4 Series, with each one coming with a different price. The base price for a variant 1 suspension upgrade is €1,100, which is about $1,500 as of 8/4/2014. Expect the amount to go up from there for more sophisticated suspension setups.

The engine upgrade is the highlight of Best-Tuning's program for the BMW 4 Series. The aftermarket company used the age-old trick of software modification to achieve an improved output of 365 horsepower, which a nice improvement from the 435i's standard output of 306 horsepower, considering there are no parts to swap out. this upgrade comes at a price of €1,299, which is $1,743 as of 8/4/2014.

Best-Tuning didn't say how much of the power bump translates to the sports car's performance capabilities. Our best guess is somewhere along the lines of a 0-to-60-mph sprint time of 5.3 seconds to go with the same electronically limited top speed of 155 mph.
