well honestly on a stock car you will notice a big difference, however if you have a car with horsepower I would recommend a name brand, I've seen people bend metal bars and I have seen guys autocrossing with stock cars and made a HUGE difference on handling, the best is if you upgrade the HP you can always sell those foward and get name brand stuff....just my 02 cents
