these look like the volk replicas.. I bet they weigh about 3 times more... weight is very important.. expect about + or - 1lb -ft per 1/2 pound.. stock rims ar 18 lbs (so if you get 20 lb rims you are losing up to 4lb -ft of torque!, and since it's a moving part after the crank, you are losing that ACROSS THE BAND).
This is in NO WAY an accurate way to measure torque gain or loss, because there are WAY more factors than wieght (like where the mass is on the rim, closer to center is better), this is just a decent way to take a ballpark stab at what your gains/loss MIGHT feel like.
The reason you pay more for volk is because of impressive engineering, they make very strong, very light rims with very good inertia ratings (shifting the mass close to the center of the rim will make it spin faster and easier). A look alike will not have those benefits.
