What is a good High Temp Brake fluid for road racing?
Good = ATE Super Blue and ATE Type 200. Same brake fluid but they're different colors so you can see when the new fluid is coming through and the old fluid has been flushed. Motul RBF600 is good fluid as well.
Having said that the above are "Good", I don't recommend either for roadracing. They work, but I would get the best (IMHO), Castrol SRF. It isn't cheap, but you'll get longer life and far superior performance.
I'd post this question in the Autocrossing and Roadracing forum. You'll get better answers there from some very knowledgeable forum members.
What is a good High Temp Brake fluid for road racing?
AP600 is hard to beat for most racing applications. If you want the very best available, AP Racing PRF and Castrol SRF are used where brake run constantly at 2000°F. SRF has a slightly higher boiling point, but PRF has much better recovery properties.
On stock brakes the ATE SuperBlue will be fine. I run it on carbotech pads and blank c5 rotors and have good enough braking performance for track day events.
There are a bunch. Here are the ones I have used. Ford Super Duty DOT 3 although it isn't quite as good as it used to be. Its dry boiling point used to be 550 but is now spec'd at 500. It's the most cost effective fluid you can buy and its straight from the Ford dealer. Back a number of years ago Grass Roots Motorsports rated as the best kept secret in racing. Wilwood 570 (dry boiling point of 570) and costs about $6.00 per 12 oz container. Wilwood 600 Plus. I used this a couple of times but it is more expensive and the 570 wasn't boiling so went with the cheaper fluid. Actually never had any problems with the Ford fluid boiling either even though dropped to 500 degrees.

100%. I only use SRF and it is worth the extra money IMO.

its still a good fluid even though its a dot4? don't the dot3 adsorb me moisture... I need something for street use just wanted to update a bit. iwas thinking the motul rbf660 or 600 since abit cheaper. Is the 660 better than the SRf?

SRF bottle is much larger than a motul bottle ( almost 2X the size). So with that said SRF runs about 2X the $$$ as motul.
I ran 20 1/2hr track sessions this year on SRF and did not bleed them once. enough said!
That was my reasoning as well. After taking into account the extra fluid cost required for multiple changes and time to do it, the SRF is a no brainer.
so for street use get the motul 600 or just stick with the gm stuff?
Motul RBF600 is a bit overkill for street use, but it works great. Alternatively, you might consider their DOT5.1 product or AP Racing Formula 5.1. Both have outstanding properties and the correct viscosity for brake systems with advanced ABS and traction control (like the C6). They will also handle a bit of track duty, but not hard core racing or track abuse. And, each costs less than the RBF600.
