Forged Rays Volk Wheels installed - stock wheels are HEAVY!

Thu Mar 31, 2011 9:49 pm

I posted in the other wheel topic about changing my wheels to lighten up rotating mass. The photo of one of my stock wheels on a scale shows how heavy they are (21 lbs):

Image

I went back and forth on which wheels I wanted for the car debating cost vs. weight savings vs. appearance. I finally found a for sale posting for this set of Rays Volk TE16's that were in excellent condition; and still had their original white coating on them. After getting them here I quickly changed my mind on the white color as it clashed with the pearl color of my car. I had them powder coated in a dark silver. I weighed them after coating and they are 10.5 lbs each. I have dropped 10.5 lbs per corner in rotating/unsprung mass. I have only put a few miles on the car tonight but I can tell some difference in the power required to accelerate. The same throttle input/KW power to the motor yields a little quicker acceleration. I can now accelerate with a little less power and help my range. It will take a few days for the car to "relearn" my driving habits and I am curious to see how much gain I will have. I drive the same route almost every day and it is on surface streets with stop and go traffic. Considering what dropping wheel weight has done for hybrids I have had in the past I am hoping for a minimum of 5-8% gain in efficiency/range. Here is a photo of the wheels on the car this evening:

Before anyone asks, no, I will not be selling my stock wheels. I am cleaning them up to put away. Also, yes, the wheels do not have center caps. I am debating whether I want to source the proper size ones from Rays as I am not that concerned about them and they are expensive.

As far as what other wheels will fit the car for weight savings, I am not the authority on that. In some cases you will have to work with a wheel company/tire dealer to source a set to test fit. The main clearance issue is the front brake calipers contacting the wheel spokes. Certain wheel designs will require a lower offset (wheel further out) to have proper clearance. The TE16s I am running, and the same would be for their newer version TE37, would need to be in the 25mm range minimum to have enough clearance. My wheels are at a 20mm offset (20mm further outwards than the stock wheels). Also, note that the stock wheels are 16"x6.5" and most replacements, including the TE16s I am running, are 16"x7". The stock tires fit great on the 1/2" wider wheels.

I don't suppose you might be willing to clue us in on how much those ran you? BTW they look sweet.

Actually, since they were a private sale (used) I got them for a great deal, and I got a good deal on powder coating, so the price is irreverent. New TE37s in the same size are in the $620 range each. These are not inexpensive wheels.

Also, when I dropped off the wheels and tires to be swapped over I put a set of 18" Rays Forged wheels on the LEAF that I have for my Mazda (just for storage in my shop/hangar, did not drive on them)... it looked so strange/funny that I took a photo (ignore the camera phone quality):

Just thought some might want to see those as well as they are still 5 lbs less than the stock wheels, but the increased size and tire width would hurt the efficiency/range over the stock wheels.

I actually really like the look of the 18's. What type Rays are those and what were the specs/offset? It will be very cool to see how shaving 40 lbs of wheel helps out on the 16's. I am amazed that Nissan would have put such heavy wheels on their first EV.

They are a set produced for Mazdaspeed Motorsports specifically for a select few models. They would not work on the LEAF. They just worked for a temporary storage solution so I did not have to leave it on jack stands. They look like cartoon/wagon wheels on the LEAF, especially in person.

Losing weight appears to cost a whole lot of money. I'd bet cost was the primary driver for the rims on the LEAF.

wow. 20mm offset is pretty low for a fwd car. I would imagine this would lead to rubbing issues when lowered. Are you saying the stock 6.5" wheels are 0 offset?

Time to lower that bad boy and hit the track!

Thanks for weighing the stock wheels. Any more pics form different angles? I's like to see how much they stick out past the fender (if at all) compared to stock

What was the weight of the car those wheels were originally intended for?

The wheels carry a 690KG weight rating, 1521 lbs each, so they are just fine. A fully forged wheel will always be much lighter than a cast wheel as the grain structure alignment in a forged wheel allows for less material to be used to obtain the same strength.

The stock wheels are 40mm offset and these are 20mm offset. They sit out flush with the fenders and they do not rub at all. I made many measurements before going through with this, I did not just shove a set of wheels on the car. I could lower the car 1.5"-2" or so without any issues. The only problem with lowering is you would end up with camber that you cannot adjust out (just swapping springs or going to coilovers); although that camber would help with clearance.

And as far as hitting the track, not my intentions. I have this car for that purpose along with a set of 255 tires for track use:

I will shoot some different photos in a day or so. The sun was setting last night so I was running out of daylight and took a quick photo.
