Yea, I cant remember what the OEM 20s weigh, but I have heard people be cautious about the TSWs being too light and getting wheel hop. But yea, the TSWs are like 22lbs, and these are around 26lbs.
But for 1/2 the price of TSWs, they could be a good alternative. Not everybody is doing their SHO to be a pure drag car. lol
