2013 BMW 3-Series by Leib Engineering

Posted on by  

Earlier this year, Leib Engineering unveiled the GT 500 tuning kit , which was based on the E92 BMW M3 . Now it’s time for its little brother - the 325i - to receive similar treatment. Though the new GT 300 kit is not as impressive as the GT 500, it still transforms the 325i into a more aggressive and more powerful sports coupe.

Most of the upgrades were made under the hood where the tuner focused on obtaining more power. To increase the power, the tuner took a standard 218-horsepower six-cylinder engine and modified the intake manifold and the engine software. Leib Engineering replaced the car’s standard exhaust system with a new one from Supersprint, a 330i performance rear silencer and valve control.

With these upgrades, the 325i delivers an additional 77 horsepower, plus another 15 horsepower that can be obtained by pushing a button on the M-multifunction steering. All put together, you get a final output of 310 horsepower, which makes it even more powerful than the top 3 Series: the 335i.

On the exterior, Leib only offers a spoiler blade made in carbon fiber from Kerscher Tuning and a BMW performance rear diffuser in matte black. On the inside, Leib added black anodized shift paddles with a short stroke.

Next, the tuner installed a set of 19-inch wheels wrapped in Pirelli P Zero high-performance tires sized 235/35R19 up front and 275/30R19 at the rear. Also installed is a BMW performance brake system with strong-acting six-piston calipers and 338 mm (13.3-inch) rotors on the front and two-piston calipers and 324 mm (12.75-inch) rotors on the rear axle.

The car was finished in a very nice pearl white with a black stripe on the car’s side.

Press Release

Little brother with mighty punch!

BMW 3-Series by Leib Engineering

Having attracted abundant public attention in the past weeks with the premiering of the Clubsport bolide “M3 GT 500”, the young tuning company “Leib Engineering” from Gießen has been taken one step further by its Managing Director Dominik Leib and his team. Even though the E92 GT 300 that was produced on the basis of a 325i does not run quite as fast as its bigger V8 brother, it hardly looks less dynamic, it is enormously less cost-intensive and can be obtained optionally even in an all-wheel drive.

The vehicle shown here is thus able to transfer its power to the road surface through all four wheels – and this was massively boosted by Leib Engineering in its capacity as specialist for efficient suction tuning. Leib Engineering indeed revived the free-sucking N53B30 serial six-cylinder engine (series: 218 Horse Power) with an additional capacity of 77 Horse Power by modifying the suction manifold as well as correspondingly modifying the engine software. The exhaust system that combines front pipes and a middle silencer from Supersprint and a 330i performance rear silencer with valve control, whose sound can be switched from "mild" to "wild" using a push button on the M-multifunction steering wheel adds another 15 Horse Power. All-in-all, the Leib’s E92 GT 300 imposes a good 310 Horse Power on the road surface thus threatening the supremacy of even the popular turbo brother 335i. The transmissions of the 6-level automatic gear system are changed to the black anodized Leib Engineering shift paddles with a short stroke, which are optimally accessible while the fingers are in firm grip of the thick steering wheel rim.

The fact that Leib Engineering has precisely thought through the overall concept of the E92 GT 300 is also underscored by the installation of a snappy and firm BMW performance brake system with strong-acting 6-piston callipers and 338 millimetre rotor disks on the front as well as 2-piston callipers and 324-sized rotor disks on the rear axle.
Thanks to its compression and rebound damping that are separate and independently adjustable, the KW coilover kit of variation 3 with which the E92 GT 300 is also fitted is very popular amongst ambitious pilots. The full road handling is finally perfected by a rim/wheel combination of the 8.5x19 and 9.5x19 inch BBS CH-R light alloy wheels and Pirelli P Zero high-performance tyres of the dimensions 235/35R19 and 275/30R19, which also strongly contribute to the impressive form of the pearl white coupé and fittingly underscore the sporty looks.
Indeed, the fact that the bodywork of Leib‘s E92 GT 300 as opposed to the serially produced version was modified “only” with a spoiler blade made of carbon produced by the company Kerscher Tuning and a BMW performance rear diffuser in black-matt is hardly believable in the face of its extremely dynamic performance.
