    So I bought a set of the NRG steel series 700 lug nuts for my 2011 mazda 3. I've had them on for maybe 5 months and have already stripped 4 wheel studs because of them. Took them to the shop and they noticed that the cause was the lug nuts itself. Anyone else have issues with NRG? I'm planning...

    I have the SK-500BK-2 shift knob and it's got the 5 spd pattern on it. NRG doesn't have any extras to give/sell. I was wondering if any of you guys would have any?? I have the '16 Axela 6spd. I just think it's weird shifting a 6spd with knob that says 5 :joy:
