This Black Sapphire 428i has it all: looks, speed and handling. The sleek coupe kept its exterior modifications to a minimum, consisting of a front lip, a rear diffuser, gloss black kidney grilles and some painted reflectors. The most noticeable change to the overall look of the car would have to be the Volk Racing TE37SL wheels. Not only do they provide a distinctive style for this BMW, their forged construction makes these wheels renowned for their strength and their incredibly low weight.
And since being light weight is one of the 428i's strengths, this F32 had a pair of Recaro Pole Position racing seats installed to shed a few more pounds.The new seats will come in handy because the suspension has been upgraded to a BC Racing coilover set-up, which allow for a lower center of gravity and firmer spring rates.
Under the hood, the 4-cylinder turbo motor has a few upgrades of its own. A JB4 tune, an Evolution Racewerks downpipe and an AFE intake all work together to unleash this 428i's potential. All in all, this car is undoubtedly a blast to drive, it looks great and it will probably give some 335is a run for their money. Take a look.
This Alpine White E92 is no stranger to us; during previous visits this M3 has been fitted with some quality modifications, including an Akrapovic Titanium GT4 Exhaust System and KW Clubsport Coilovers. This time around, our attention was primarily focused on the exterior. To go along with the BMW Performance Carbon Fiber Trunk Spoiler, we installed Mode Carbon's aggressively styled LM Series Carbon Fiber Rear Diffuser. Featuring a sharper, more angular design than other carbon fiber diffusers on the market, the Mode Carbon LM Series diffuser helps this Alpine White M3 stand out from the crowd. On the inside, this M3 is fitted with Recaro Pole Position Seats and a BMW Performance Alcantara Steering Wheel. To tie the whole interior together, we installed a Macht Schnell MS97 Spec Shifter Knob for a true motorsport-inspired look and feel.
We featured this Alpine White M3 on our blog last year and noticed that that it quickly became a fan favorite. It's pretty easy to see why. After all, it isn't everyday you see an M3 with an Akrapovic GT4 exhaust system, a VRS System 1 diffuser, BBS FI wheels, Brembo brakes, KW Clubsport coilovers, a Mode Carbon lip and Recaro Pole Position seats. Just when you thought this BMW was as good as it gets, we went ahead and made it better. During it's most recent visit to our facility we installed the ESS VT2-625 supercharger system and introduced this E92 to a whole new world of power. With the supercharger system installed, this M3 picked up 170 horsepower at the wheels and made as much torque as it did power when it was NA! Because this M3 is already equipped with upgraded brakes, wheels and suspension, the neck-snapping acceleration will fit right in.
Since our project M3's primary intentions will be track duty, safety is #1 concern. Race seats and a harness bar are up next on the agenda.
Recaro Pole Position seats were chosen for this build. Black cloth will match the speedcloth interior on the door panels, breathe easily and will last for years both on and off the track. 3-point belts will be retained for the street, a set of Schroth harnesses will be utilized at its upcoming track event next month.
On the hardware end, Macht Schnell had everything covered to allow a fully bolt-in installation for the Recaros, as if it were originally offered by BMW themselves. There is zero flexing - you are locked within the seat during spirited runs.
With seating taken care of, we called upon VS Motorsports in Chicago to fabricate a harness bar for us in 4130 Chromemoly steel. Weighing in at a hefty 80lbs, this is built for strength, with sharp looks following after. The harness bar is very well built and allows minimal gap between the factory headliner and main hoop.
Next up on the list are Gauges. The M3 comes very little equipped in terms of monitoring vitals. Going to a boosted setup, three gauges come to mind:
- DCT Fluid Temperature
There is very little space to mount gauges in the E9X chassis, we will be using the Macht Schnell Ashtray Gauge Panel for this build. Housing (3) 52mm gauges, we will always be able to keep engine vitals at a moment's glance, without being too obtrusive to the interior.
