New Concave Wheels and Motorsports Upgrades for the BMW M235i

The BMW M235i becomes a potent track beast with a host of new upgrades from Manhart. The team added on new concave wheels, engine upgrades, and interior goodies for the German coupe.

The BMW M235i may not have the same cache as the BMW M3 or M4 models, but it is quietly stealing the hearts and minds of true BMW enthusiasts. Not since the E46 generation BMW M3 has there been a car that compares in size and driving dynamics, and its performance. This has made it a favorite among automotive enthusiasts and it got even better thanks to the help of the German tuners at Manhart. The engineering team was able to design a full motorsports-oriented upgrade program that includes lightweight modifications and aerodynamics along with new concave wheels. Armed with these new modifications, the BMW M235i becomes a serious track day monster.

 

Aerodynamics always plays a key factor in racing and motorsports, so the team at Manhart decided to add on new parts to the BMW M235i. The front fascia benefits from a new OEM M Performance Parts carbon fiber front spoiler while the rear wears a new OEM spoiler and diffuser in lightweight carbon fiber for more downforce. Between the newly installed concave wheels sit a set of carbon fiber side mirror covers. To finish the design, a new dull yellow vinyl wrap was applied to the entire body except the carbon fiber pieces.

 

The next step was to improve on the BMW M235i’s handling dynamics and characteristics. Here, the German aftermarket specialists added on a new KW high performance suspension that can be adjusted in terms of height, bound, and compression and comes with support bearings and a custom alignment. The factory rims were swapped out for a new set of lightweight concave wheels with a gunmetal grey finish. The setup of the concave wheels measures 8.5 x 19 up front and 9.5 x 19 at the rear with high performance Michelin tires. Behind the new rims sit six-piston brake calipers with larger discs, stainless steel lines, and high performance pads.

 

The turbocharged 3.0-liter inline-six cylinder engine holds a lot of potential that the Manhart team was able to tap into with a few modifications. A larger intercooler system was installed along with a new stainless steel 90 mm exhaust system that includes 200-cell catalytic converters and new downpipes to reduce backpressure. The factory ECU was given a new tune with standalone software programming to send a total of 430 horsepower and 437 lb-ft. of torque to the rear concave wheels.

 

Inside, Manhart swapped out the factory front seats for new lightweight Recaro shells and deleted the rear bench in place for new braces. A new driver display system was also installed on the dashboard to provide relevant information and timing.
