    • HRE drops just over 32 pounds off a BMW F82 M4 GTS just by changing the wheels

      The BMW F82 M4 GTS is supposed to be the highest performance BMW in the lineup and ready for track duty out of the box. For the asking price of $134,200 you expect to have great equipment.


      The Ford Shelby GT350R Mustang is half the price yet it comes from the factory with lightweight carbon fiber wheels. What exactly are people paying for on the M4 GTS?

      HRE shaves 32 pounds just by switching to their R101 wheels. This is with a wider rear wheel:

      BMW was supposed to shave close to 300 pounds yet missed their claimed M4 GTS weight targets completely.

      It's no wonder the M4 GTS is getting beaten by everything.

        I don't even understand why anyone would want to collect it.

        The GTS wheels look like they were taken off an 87 Trans Am.

        Now that we have some weights on these R101's I'm considering them.

        They definitely look awesome. Is there a difference in price between the regular R101s and the R101 LWs?

        The LW's are more expensive by $200 per rim.

        Been trying to find out more info. @HRE_Jurrian

        Forgeline has some pretty awesome 911 wheels too, I absolutely love the GA1Rs, I believe Sharkwerks and Dinan use them also.

        Feel free to edit/delete my thread if posting pricing isn't allowed. You are correct though that R101 Lightweight's are $200/per wheel more than the standard R101.

        In 19" for example, R101's would be $2200/per wheel, R101 Lightweights in 19" $2400/per wheel.

        Here are some R101 Lightweight examples from various models:

        19 x 9.5 ET22 = 16.7 lbs
        19 x 11 ET43 = 17.6 lbs

        Here's a R101 Wheel set to give you an idea of the cost difference vs weight difference between these two wheels.

        19x9.5 ET20 – 19.2 lbs
        19x11 ET37 – 20.6 lbs

        Weight difference for fronts - 2.5lbs per wheel
        Weight difference for rears - 3.0lbs per wheel

        I think we can let it slide. I wanted to see the details myself.

        Can you do these RS101 Lightweights in any finish?

        Yep, any finish off our long list of finishes (The finish list got even bigger, we're looking at 70+ finish options now).

        Awesome. Mostly I'm interested in this finish. Brushed gold it is I guess?

        Ok and do you know what wheel that is? Is it much heavier than the R101?

        On the Porsche's those look to be P101's which will have less pocketing on the sides of the spoke, and less pocketing around the center of the wheel as well.

        To give you an idea though, a 20x8.5 ET50 P101 wheel with a high offset conical profile will weigh 20.40lbs.

        If you compare that to our 20x8.5 ET55 R101 Lightweight with a high offset conical profile, will weigh 16.00lbs.

        Comes out to 17.6lbs of unsprung weight in total (4.4lbs per corner)

        Thanks Jurrian. Just to make sure, same finish here right? Looks different in different light:

        Yep those are Brushed Gold as well. Any Brushed wheel we make will appear slightly different in sunlight depending on the finish color because the color applied is not a solid thick powdercoat like a Satin Black for example. With a Brushed finish we can still utilize the reflectiveness of the aluminum underneath that layer of color and clearcoat which allows the color to pop more especially in sunlight.

        Thanks for answering my questions. Definitely considering a brushed gold set of rims.

        Damn for a 16 lb wheel these things are badass! I can't really tell the difference between the P101 and the R101 lightweight.
