Eddie: Works great no more spongy brake. I used this in my snowmobile and it fixed the problem. And yes the date on the bottle is not this year but anyone that knows oil and fluids that unopened they have no moisture. This worked and has no issues

Nicholas w.: Unlike Sport bikes, quads and dirt bikes snowmobiles weigh more and only have one caliper and rotor to stop you. This is fine for average riders but when racing these brakes build up unreal amounts of heat in a couple corners. (Will literally melt my boot to the brake guard that's right next to my foot). Even with these conditions however i feel very little brake fade even on some of the tightest sections of the tracks. While with brand new dot 4 fluid that youd buy from an auto parts store would only last maybe 3 laps on a ice oval before boiling this fluid seems to never boil. I do replace it right before every race however to avoid any boiling.

Benjamin Busch: The best stuff on the market in my opinion.. I used 660 in my track mustang, truck, and 3 motorcycles and the consistency is great. Good luck trying to boil this stuff! The fact that it is so resilient means your braking will be consistent which translates to faster lap times and increased safety. Or if you just want to have the absolute best in your vehicles and don’t care if it’s “overkill,” this is the stuff for you! JUST BUY IT ALREADY!

Austin Rexinger: I purchased this fluid for my Focus ST. I regularly race my car at autocross, time attack, and some track days. I read good things about this fluid so I pulled the trigger, and I couldn't be happier.
Unlike with the stock fluid, there is zero fade during 7-8/10 driving and barely and fade when driving at 10/10. Worth noting-- I also replaced the stock pads with Hawk Performance pads at the same time as the fluid. I've driven my car on track for over 10 minutes at a time with speeds nearing 120 mph and pedal feel held up.
It's a bit pricey, but not unreasonable.
