NOTE to G35 Sedan owners: The sway bars are not being sold as a fit for the sedan, but there have been a couple of people who have come forward to mention that they fit on their sedan without any problems.

Quality and performace are on par and in some cases even better. Progress Technology has extensive racing background - starting out in the Honda/Acura market, but developing thier efforts in the broader range in previous years. They don't just bend some springs up, or bend a couple of bars and say - "here, here's your "performance springs and sway bars!". They do extensive development for each vehicle by tuning the spring rates and sway bar thicknesses to work optimally with that vehicle. Real world street testing and track testing, dyno tuning, and test vehicles are all used. and they aren't just tuned to work on the track, they consider all the factors when designing their performance parts to be real-world friendly, so spring rates are so stiff that they shake the fillings out of your teeth on your morning commute, but they don't disappoint in making sure you smile when you do some spirited driving during that commute!

Some of the other "big name" companies actually buy their springs and bars from "outside sources", and call them their own. Mass-produced from other countries for mass distribution to the US market. No custom tuning or testing is really done to make their setup optimal for your car. It's reasons like that that we chose to work with Progress Tech exclusively.
