Gentlemen,
The moment of truth has arrived.
First test was done on a typical shipping scale, measured in lbs.
Traditional Rounded Wheel Spacer - 15mm 5x120 72.56mm CB
End Result - 1.0 lb
Verstraβe Motorsport Wheel Spacer - 15mm 5x120 72.56mm CB
End Result - 0.6 lb
Traditional Rounded Wheel Spacer - 10mm 5x120 72.56mm CB
End Result - 0.6 lb
Verstraβe Motorsport Wheel Spacer - 10mm 5x120 72.56mm CB
End Result - 0.4 lb
Traditional Rounded Wheel Spacer - 5mm 5x120 72.56mm CB
End Result - 0.2 lb
Verstraβe Motorsport Wheel Spacer - 5mm 5x120 72.56mm CB
End Result - N/A (scale not sensitive enough to record such light weight)
Note that this kind of weight scale is not the most ideal for measuring items that weigh less than 1 pound.
As such, for the next test - we performed on this more sensitive scale, measured in ounces.
Traditional Rounded Wheel Spacer - 5mm 5x120 72.56mm CB
End Result - 4.5oz / 0.28 lb
Verstraβe Motorsport Wheel Spacer - 5mm 5x120 72.56mm CB
End Result - 2.8oz / 0.175 lb
Traditional Rounded Wheel Spacer - 10mm 5x120 72.56mm CB
End Result - N/A (spacer weight end result out of available range on this particular scale)
Fortunately, the Verstraβe spacers in 10mm / 12mm / 15mm were light enough to be measured on this scale, so without further ado - here are the rest of the results!
Verstraβe Motorsport Wheel Spacer - 10mm 5x120 72.56mm CB
End Result - 6.075 oz / 0.379 lb
Verstraβe Motorsport Wheel Spacer - 12mm 5x120 72.56mm CB
End Result - 7.495 oz / 0.468 lb
Verstraβe Motorsport Wheel Spacer - 15mm 5x120 72.56mm CB
End Result - 8.925 oz / 0.557 lb
And here are a few more pictures detailing direct comparison of the traditional rounded wheel spacer versus the Verstraβe Motorsport Weight Optimized Wheel Spacer.
