Shawn Robertson's E46 M3 sedan

When I first got back into a BMW from a couple year break (2009) I had chose an ‘03 330i sedan. I promptly stumbled onto the E46fanatics forum to dive deep into my new obsession and research everything that I possibly could about E46’s. It was pretty fast for me to realize that an E46 M3 was my new “realistic” dream car, but at the time it never looked obtainable. So I did pretty much what the majority of people do with non-M cars and upgraded with OEM+ modifications to make it look as much like the M as possible. At that time I dreamt of eventually building my car into an M3 sedan (because of JeppeJ's Interlagos Blue M3, look it up if you haven’t seen it before.)

Anyway, S54 swapped E46 non-M’s aren’t that uncommon nowadays… but a full out conversion is a little more rare. So I was extremely happy to see that Shawn was in the process of doing this to his ZHP. I was already a huge fan of his car in its ZHP form so I knew it was going to be great. The attention to detail and goal to build it as close to a factory M3 is very apparent. This is one of the cleanest conversions I’ve seen since JeppeJ’s, as I hold that to the highest standard in which one should be done in.

Shawn originally was in the market for a stock ZHP 6 speed. He bought the car sight unseen from a ZHP dealer in Fort Lauderdale, Florida. He was excited to drive the car since it had been about 11 years since he last owned a BMW. His last car was in 2005 which was a 1995 Avus Blue turbo E36 (making 601whp). Once he started looking at forums like E46fanatics, ZHPmafia, and M3forum it didn't take long for the itch to set in and before he knew it he bought an M3 parts car from Copart… before he even knew how to do an S54 swap mind you. So Shawn had his buddy at Lins Specialty Automotive perform the full mechanical S54 swap since he had a lot going on in his life and he needed some help.

He drove about a year on that and during that year he decided to retrofit and equip the car with every rare option he could think of. Once he completed that he picked up a wagon and another parts car to make an S54 wagon to sell. Before he tossed that sell he scavenged all the body parts to start his M3 body conversion. He had Superstar Customs in Lilburn, Georgia do the rear fender flares and contacted 2M Autowerks for their fiberglass front M3 sedan fenders. Born2doit customs painted the car in Imola Red and then he decided he wanted something close to an E46 M3 CSL sedan.

Currently the car has 174k miles and though he wished he had started with a lower mileage chassis, he loves the car and the work that went into it. It’s his one of a kind car. For now he just wants to enjoy it and would love to eventually pass it down to his son in the future.

BMW unveils the special edition 435i ZHP Coupe

Woodcliff Lake, NJ – May 19, 2015… Paying tribute to the iconic ZHP Performance Package, BMW today released details for a 2016 BMW 435i ZHP Coupe Edition. The original ZHP option code was created by BMW Individual as a performance package for the 2003-2006 E46 3 Series that included the M-Tech II body kit, a ZHP shifter knob and shifter, upgraded suspension parts and settings, a different DME and special cam shafts that raised power output to 235 hp and allowed for a higher redline. Fulfilling the desires of true enthusiasts, the package was soon referred to by its internal option package code ‘ZHP’. BMW of North America embraced the thirst for the unique BMW 435i ZHP Coupe Edition once more resulting in the unique collaboration between factory options and key elements from the exciting BMW M Performance Accessory catalogue. Only 100 of these very special cars will be offered.

The new BMW 435i ZHP Coupe Edition is not just a vehicle with improved optics and aerodynamics; it is also notably quicker with more precise handling. These components take the vehicle’s capabilities to levels that those familiar with BMW’s racing heritage can appreciate. The BMW M Performance line of accessories provides a distinctive, sporty character to further enhance driving dynamics and is the result of years of racing expertise and has been developed in close collaboration with BMW M GmbH. Each component goes through an intensive development and manufacturing process resulting in uncompromised performance. Exclusive chassis, aerodynamic, cockpit and powertrain components are found throughout the BMW 435i ZHP Coupe Edition. Key characteristics are:

  • Track Handling Package, new for MY16
  • BMW M Performance Limited Slip Differential (LSD)
  • BMW M Performance Parts
  • M Sport Package


Track Handling Package
Designed to increase the dynamic capabilities of the already agile BMW 435i, the Track Handling Package adds 18” Orbit Grey V-Spoke Wheels and M Sport Brakes with 4 piston fixed front and 2 piston fixed rear calipers adding to the vehicles thirst and drivers demand for speed and acceleration. Moreover, this package incorporates the Adaptive M Suspension with variable damper technology as well as Variable Sport Steering.

BMW M Performance Limited Slip Differential
Designed and created for BMW enthusiasts, the mechanical Limited Slip Differential provides the extra performance advantage that true performance drivers desire. This differential utilizes 3 clutch plates for a total of 30% lockup on acceleration and 9% lockup on deceleration. This lockup provides instant power to the wheel that has the greatest amount of grip to gain better traction out of tight corners. An additional benefit in low-grip situations is that both wheels get equal torque, meaning more forward driving force on roads with reduced traction. The M Performance limited slip differential optimizes the traction, and ensures more controlled and precise driving behavior at the vehicles limits of adhesion. The M Performance LSD is a true advantage while at the track or in sporty driving situations.

  • The advantage can be felt at the track and in everyday driving. The improved vehicle dynamics are clearly present with the LSD as more torque can be transferred to the road at any given time, allowing for quicker acceleration out of corners.
  • Traction is improved for any type of road condition.
  • The LSD integrates seamlessly with the vehicles’ DSC system.


BMW M Performance Engine Kit (+35 hp, up to +32 lb-ft)

The BMW 435i ZHP Edition gets an exhilarating boost in performance thanks to the new M Performance Power Kit enabling an unprecedented level of acceleration and speed. The BMW M Performance Power Kit features engine tuning software and a new M Performance Engine Air Intake system. In addition, a replacement M Performance Engine Cover and Rocker Panel Decalsprovide visual distinction this special edition vehicle deserves. Power and torque figures are now updated as follows:

  • Horsepower increased to 335hp (35hp gain).
  • Torque is increased to 332 lb-ft (automatic transmission, 32 ft/lb gain) and 317 lb-ft (manual transmission, 17 ft/lb gain).
  • Improved acceleration that drivers can feel immediately when compared to a standard 435i:
  • 0.2 seconds faster than the standard 435i model from 0 mph to 60 mph.
  • 0.5 seconds faster than the standard 435i model from 50 mph to 75 mph.
  • More dynamic accelerator pedal calibration in Comfort, Sport and Sport + Modes, provides an even quicker engine response.
  • Exhaust “burble” sound during engine overrun conditions. The M Performance Power Kit ensures an optimized engine and exhaust system sound. The exhaust “burble” is enabled in Comfort mode and amplified even further in Sport mode. As a result, the car sound amplifies 'performance'.
  • Sport Display now shows increased power figures (400 hp and 400 lb-ft) to reflect increased performance.
  • The M Performance Rocker Panel Decals give the car a sportier look, even from the outside, providing a hint of the car's hidden performance.


BMW M Performance Exhaust
The stainless-steel M performance Exhaust sheds 8.8 pounds of weight while also reducing backpressure for improved dynamic performance, producing a sound that is perfectly balanced for performance and comfort. Two stainless steel tips with a brushed finish connect to a muffler with a straight-through design.


BMW M Performance Aerodynamics Package
The BMW 435i ZHP Edition is also enhanced by the addition of the M Performance Aerodynamics Package. This package underlines the sporting appearance of this special edition vehicle. It comprises of the following components: A front and rear spoiler made from high-quality carbon, as well as a rear diffuser made from PUR-RIM a specially crafted high quality polymer. The dynamic elegance of the M Performance Aerodynamics package amplifies the vehicles exemplary sportiness even further. Above all it offers optimized aerodynamics and accentuates the car's sporty driving behavior.

  • Made entirely from carbon fiber reinforced plastic (CFRP), the design of the front M Performance Front Carbon Fiber Splitter and rear M Performance Carbon Fiber Spoiler give the BMW 435i ZHP Edition a powerful appearance.
  • 3 striking, embossed bars are integrated into the design of the rear M Performance Diffuser. Their pointed appearance accentuates the car's sporty character.
  • The integrated expanded grille in the rear diffuser painted in matte black produces an additional motorsport feel.
  • M Performance Black Kidney Grilles round off this striking BMW M Performance Aerodynamic Package.


M Sport Package
The BMW 435i ZHP Edition incorporates the M Sport Package comprised of the front and rear Aerodynamic kit, Aluminum Hexagon Trim with a Black high-gloss accent and an M Sport steering wheel.

Only 100 BMW 435i ZHP Editions will be produced making it an exclusive option for customers in search for something truly special. Available with either a Sport Automatic 8 speed or a 6 speed Manual Transmission, the customer can choose to drive either an Alpine White or Black Sapphire Metallic BMW 435i ZHP Edition.
