What was the difference you perceived? Reduced fade? Better pedal feel? Stiffer?
I only skimmed the other replies but I think it was mentioned already.

Fluid doesn't compress, so the pedal didn't "feel" any different. Water in the system would feel the same when sitting in the driveway.

The fade was nearly eliminated (stock pre 04 pads). Any fade I did feel was consistent. Brakes were much easier to modulate with a very consistent pedal feel. After a few sessions pedal travel was slightly different but still FIRM. I had much more confidence on the straights pushing to the furthest possible braking point.

My gf and I drive this car at the track. The last driving school we attended the car was basically on the track the whole day. I get off, pull over on the pit lane and toss her the keys leaving the door open LOL (sushhh I didn

As far as autox, if the fluid is able to cool down it doesn't matter how many times a year you heat it up as long as the max temp isn't boiling. Intensity is the key, not frequency.
This is a bit vague. Yes intensity but there's no CUT line right (other than the DBP and WBP)? Even if it doesn't boil you're still breaking it down. A lower quality fluid can/will break down faster right?

Boiling introduces bubbles in the line producing that spongy pedal feel. I have boiled fluid before and the drive home (even though I let the fluid cool) was not soo fun.

Correct me if I'm wrong, but that was my understanding.

Even with a two year water gain most DOT4 fluid has better numbers than most DOT3 fluid. For street it make little difference unless you come down a mountain at speed which will make brakes hot enough to need a good high number. AutoX just does not tax brakes enough to make any difference.

IMO the Valvoline stuff is a good choice for the street and some track although I use Motul 600 now because of hard track use.

I posted on this in depth - just cannot go over it again.

DOT3 and DOT4 are not identical. Unless you race, or autocross race, I do not see the benefit of going to DOT4, since one will almost always have to change the brake fluid more often, esp with the exotic DOT4's like ATE, Motul, etc.

I recommend using Ford DOT3 fluid. It has excellent wet and dry bulb temp performance, its DOT3 formulation ensures absolutyely no issues with Honda's spec or seals, and it is available and cheap.

Ford dveloped its "super 3" when Lincoln found that the elderly Town Car drivers were riding the brakes, causing the fluid to overheat, blowing seals and lines, warping rotors, etc. Since they cannot ride around yanking geezerly Wallabees off of TC pedals, they just engineered the best dern DOT3 there is.

Flame suit is ON.

I used the FORD DOT3 fluid for a while. It did work well but I managed to boil it

Here's a thread with all the boil temps of various brake fluids.

I like the ATE SuperBlue/type200(gold) because it's relatively cheap at $10/L and you can interchange them and see the color change when you bleed.

Ford DOT3 brake fluid is available only at Ford dealers ? can I get it somewhere alse ?

Our S2000's are best with non-Honda fluids:
Transmission: GM Synchromesh Friction-Modified
Differential: LE 607
Brake and Clutch: Ford DOT3
Engine oil: Havoline GF-4

Only coolant fluid is Honda

I tried motul rbf 600 this year and I'm now SOLD. Won't put anything less in now.

i tired superblue and i tried Motul and im sold on the Motul, this is really good stuff especially if you couple it with some decent pads like cobalt specVRs, its a great road course combo

i wonder if i could tell a difference if i switched to the Castrol brake fluid
