2013 BMW M3

Description

Chassis and Suspension

The suspension foundation is an MCS 2-Way Non-Remote (2WNR) coilover kit, factory fresh at installation and subsequently rebuilt by MCS — the gold standard for E9X M3 track applications. Penske bump stops are fitted up front. Vorshlag camber plates allow precise corner-weight and alignment dialing.

The rear subframe was upgraded with Turner Motorsport aluminum subframe mounts and bushings, and the rear trailing arms, camber links, and sway bar end links have been replaced with Turner poly-bushed components. Upper and lower rear control arms are Turner aluminum items. H&R 27mm front and 23mm rear sway bars replace the factory units. A corner balance and alignment have been performed at HSM as part of the most recent rebuild cycle.

Brakes

The braking system is built around a Performance Friction 4-piston big brake kit with 372mm slotted rotors — a system that costs over $3,300 in hardware alone. Stainless steel brake lines are fitted front and rear. The system runs Castrol SRF racing brake fluid, which carries the highest dry and wet boiling points of any commercially available DOT fluid, flushed on a consistent schedule. Current front pads are PFC 08 compound — the preferred specification for this BBK. Rear pads are PFC 11. The brake vacuum system, including the pump, switch, and associated grommet, was recently replaced by HSM.

Drivetrain and Cooling

The DCT transmission has been replaced with a low-mileage unit (sourced from a 2011 E92 with 48,000 miles, installed by Quantum Speedworks at VIR), rebuilt again by AV Motowerks following identification of a broken cooler O-ring in the cooling circuit, and subsequently replaced a final time by HSM. The current unit is freshly serviced. A Fall Line billet aluminum DCT pan is fitted. The engine carries a VAC rod bearing upgrade with ARP bolts — the single most important reliability modification for high-revving track use of the S65. Engine oil service is performed with Redline 15W-50 on a strict schedule. A CSF engine oil cooler is fitted

and has been inspected regularly. The Turner Motorsport underdrive power pulley kit reduces parasitic losses. An AFE Stage II Pro5R intake is installed. The Akrapovic Evolution exhaust is fitted with an Epic DME and DCT tune — a combination that extracts meaningful additional power and transforms throttle response and transmission behavior. Randy Mueller (from Epic) has put his custom touch on this tune.

Aero

The aero package is legitimate: a Bimmerworld GTS wing, full splitter with integrated brake ducts, and dive planes ($9,000 installed by HSM). The splitter was originally a Bimmworld carbon fiber unit. A Vorsteiner Type II rear diffuser rounds out the underbody. The result is a car with meaningful aero balance — not cosmetic additions.

Safety

The interior has been properly configured for track use. OMP HTE-R 400 FIA-rated fiberglass bucket seats are installed on both sides, with a Macht Schnell airbag emulator and resistor pack on the passenger side. A Schroth Flexi 6-point FIA 8853-2016 harnesses are fitted on both sides. An Autopower roll bar provides supplemental cage protection. Tow straps front and

rear are fitted.

An AiM Solo DL 2 data logger (not included) with CAN interface is installed, along with an AiM SmartyCam 3 (included). Garmin Catalyst not included, but mounting hardware and camera are included.

Build history

The last of the naturally aspirated M3s, built right and tracked respectfully.

This 2013 E92 M3 Coupe was ordered with both the Competition Package and Cold Weather Package, representing the pinnacle of BMW's high-revving S65 V8 era. Since its acquisition, it has been developed methodically into a serious, well-sorted track car — not a garage queen, not a weekend warrior, but a machine that has posted a 2:08 at Watkins Glen and a 1:00.01 at Lime Rock Park. All while being able to drive the car back home.

The build philosophy has been consistent throughout: invest in durable, high-quality components; maintain meticulous service records; and keep the car reliable enough to drive to and from the circuit. Over $47,700 in documented durable upgrades and a comprehensive wear-item replacement history spanning years of track use accompany this sale. The next owner inherits a platform that required no guesswork — everything has already been sorted.
