DOT4+ Brake Fluid
I been trying to find DOT4+ brake fluid in my local auto stores however they don't carry it. Could someone let me know where they purchase the DOT4+ brake fluid from. I have a 2004 crossfire coupe. Thank you.
Rob at Needswings carries the Stop-Tech brand and may be able to order other brands as well. Check with local speed shops as they probably could order for you too, but through them they may have a minimum order that is twice the quantity you need. ( the voice of experience)

Below is a side by side of the two compaired.
(% of moisture/boiling point)
DOT 4 DOT 4+
1% 446F 1% 527F
2% 383F 2% 428F
3% 347F 3% 383F
4% 320F 4% 365F

In so many words, DOT 5.1 fluids are simply DOT 4-type fluids which meet DOT 5 performance requirements. Because of this, they typically can be mixed with DOT 3 or DOT 4 fluids without concern. In some circles, they are even referred to as ‘DOT 4 Plus’ or ‘Super DOT 4’ fluids because they are more similar to a conventional DOT 4 fluid by chemistry than they are to a conventional DOT 5 fluid.
While it may not be obvious, the big advantage of the DOT 5.1 fluids is that they contain all of the nifty water-absorbing characteristics of the DOT 3 and DOT 4 fluids while simultaneously providing for very high boiling points and relatively stable viscosity over a wide range of temperatures.
