Manhart has lifted the covers off its MH3 600 and MH4 600 versions of the new BMW M3 and M4, featuring over 600hp.

If you aren’t a fan of how the new BMW M3 and M4 look then you may want to look away now as Manhart hasn’t opted to work on that. There is, however, a new carbon fibre front bonnet, front splitter, rear spoiler, diffuser and side skirts to help detract attention from those grilles!

Based on the Competition variants of those models, the Manhart MH3 600 and MH4 600 get a MHtronik Powerbox, boosting power to 620hp and 553lb ft of torque, that’s around a 110hp and 80lb ft power hike. The non-Competition models see power rise to 590hp, over the standard car’s 490hp.

A Manhart cat-back exhaust system also features and comes with twin carbon tailpipes with the option of a middle silencer. There is also the option for a OPF-back exhaust system, too.

Manhart MH3 600

Thanks to its partnership with H&R, lowering springs are brought in to drop the Manhart MH3 600 & MH4 600 ride heights, while the car sits on Concave One forged wheels with 265/30 21 tyres at the front and 305/25 21 tyres at the rear.

Manhart says: “Phase 1 of the tuning program includes a wide variety of parts and options, which will allow clients to tune and upgrade their beloved new Bimmer. For the second phase MANHART Performance will go a step further, taking both the M3 and M4 to the next level. Stay tuned for the release of this tuning package later in the year.”

All of the parts listed here are available as packages or as individual items.
