I never got the love for wide bodies. Idk, on ground up race cars Okay, on a daily, no way. Hey that rhymed...lol

[TravyTrav]

We actually have a couple kits already sold. Price is not that bad if you factor in 20" wheels and an entire kit that is made out of Carbon Fiber

You are dead-on at $24,995 price point

3. Clay Modeling Continued:
Rear bumper shaped in conjunction with the rear diffuser and over fenders.









Shaping the fender and bumper separation for the final clay modeling stage.


4. Beginning the Molds:
Prepping for the messy part...






5. Cutting and closing:
Now the scary part begins... drawing the line to cut the rear quarter panels.


A critical step to fit the massive 20x13.5 wheels with 345 Pirelli tires.


Sanding off the paint to allow for adequate bonding.


Fiberglass applied to close up the open quarter panel.


Working on the rear quarter panel flange for a seamless fit rather than screws or rivets.


6. Installation and testing:
Molding the quarter panel to the car


CNC rapid prototype fitted


And shaped with the existing M4 side vents


Measuring the wheel fitment to maximize inner and outer clearances:


20x13.5 wheel cut yet unfinished. Mounted with 345 Pirelli's for test fitting before brushing and powder coating.

Rear overhang looks a bit much in that last pic but I'll reserve judgement till I see the final product. The rest looks fantastic though, especially those wheels. They suit the car perfectly.

Just wish the car was painted in a different color. Ruby black would've been

Yup, that's the price I got quoted from my vorsteiner dealer.

However to be absolutely honest, it's not that bad. I mean, wheels alone would cost around $10K. And $15K for the rest which includes the bumpers and lip is not "that bad".

When I nearly went ahead with this project a year ago, after adding installation and paint cost, the overall price was sitting around $40K. Installation and paint alone was roughly $12-$15K.

Hard to tell what its presence will be cuz holy FK is that ridiculously wide. Impressive for sure! Cant wait

[BESTNDA416]

dammmmmmm

[MWS55]

That looks mental...

Wheels for 10k?? Those wheels better be darn good! I'm hesitant on spending that much on HRE's already so idk about wheels from Vorsteiner. And from a majority of the forum members on here already complaining about 4k exhausts they are not going to be fond of this price tag haha

This will be at SEMA?

[GOLFFRR]

you have to cut the rear fenders to install the kit?

Def looking forward to seeing the final project. Sema is going to be insane this year! So many M's

Any add on kit needs to be cut if you want to fit wheels that match the kit. Otherwise you're stuck doing OEM M4 fitment on a much wider body!

Yes you do have to cut the rear fenders. It is going to be a great SEMA sir!

Quick pic for you guys

I wonder if the M3/M4 will win the car of the year!

from the looks of it there will be a lot of M3/M4 contenders!

Looking forward to seeing this thing. The progress looks awesome.

Via Vorsteiner Release:

The Special Edition GTRS4 World Premiere

Vorsteiner is celebrating our 10 year anniversary this year and to commemorate this occasion we have developed a very special limited edition vehicle, code named GTRS4 debuting at the 2014 SEMA Show. The GTRS4 is a full lightweight carbon composite wide body conversion that is based on the 2015 BMW M4 coupe. The design and development of the GTRS4 started early this year as there were countless hours of testing and modeling that took place.

Design of an Icon:
The idea was first conceived on a blank sheet of paper where our designers took into the consideration the previous historical wide body editions such as GTRS3 based on the E92 M3, to show a lineage in both Vorsteiner design language, functionality and performance.

Our designers focused making the design organic to the original body lines of the car while retaining full functionality & everyday drivability of the vehicle. It was not enough just to make the widest possible fender as it was also dictated by the ability of the wheel to turn while under load at high or low speeds.

We also wanted to ensure the design paid tribute to M3 racing heritage and lineage while still maintaining the minimalistic Vorsteiner concept,

The Beginning of a Legend:
Once the design was sketched and finalized on paper we 3D scanned the entire factory body using Blue Light Laser Technology. With our 3D renderings, we digitally surfaced the new body panels and created CNC rapid prototypes to fit on the vehicle.

The most crucial step was the rear quarter panels as it was very important to create a perfect contour. In order to effectively create, readjust and improve this shape, our in-house master craftsmen utilized traditional clay modeling to achieve seamless and fluid proportions.

Form Follows Function:
From the original launch of the development process, our design and engineering team worked in tandem to ensure the wider fenders and wheels were functional. We strategically crafted air ducts for optimal cooling towards the front brakes, while paying attention to aerodynamic ventilation for the inbound air to exit.

The front fenders have a total span of 4 inches while the rear quarter panels sit 7 inches wider than it’s original form. We’ve specially designed 3-Piece Forged wheels in 20x10.5J and 20x13.5J respectively to fit the 275 and 345 width tires.

The vehicle is also fitted with Pirelli’s signature P Nero tires for optimal traction and performance. To add to the stance, our GTRS4 features KW Suspension’s sleeve kit allowing for height adjustment as well as keeping the original BMW Dynamic Drive features. Adding to the performance, simplicity, and versatility, the GTRS4 is upgraded using ESS Tuning’s E-Tronic for an impressive 550hp to the crank.

The Special Edition GTRS4 Package Includes:
· Carbon Fiber Front Bumper with an Integrated Front Splitter Element
· Carbon Fiber Wide Front Fenders with Ventilation (2 inches wider each side)
· Carbon Fiber Aero Side Blade Elements
· Carbon Fiber Wide Rear Fenders (3.5 inches wider each side)
· Carbon Fiber Rear Bumper with an Integrated Rear Diffuser Element
· Vorsteiner 90mm Quad Exhaust Tip Finishers (Options: Brushed | Diamond Black)
· Vorsteiner Embroidered Colored Floor & Trunk Mat Set
· Vorsteiner Chrome Trunk Badging
