About to install my new rotora front bbk within the next few days but need to pick up some brake fluid.

Is the price really worth it for motul and whats the benefits?
What do you guys recommend and how much do I need?

Thanks

If you just do normal driving, use regular Dot 3. If you do anything more, than you can go with Motul. It only gives you benefits if you are braking constantly at high speeds.

^^^ You'll need 2 bottles to fully bleed/refill the brake system.

I dont track the car but I do drive HARD on occasion.

The benefit of the Motul brake fluid is it has a higher boiling point. This will keep your brakes from fading due to excessive heat. If you do not track the car, Factory Honda fluid will be just fine. You will not be able to boil the fluid for street driving. If you want the Motul it will not hurt anything, it just is not needed for your situation.

Is there a large difference between the rbf 600 and 660?

If you're just using the car on the street and maybe light track the MOTUL DOT 5.1 is fine. It's a synthetic brake fluid compatible with DOT 3/4. RBF600 is more for track cars or cars driven really aggressively; it will need to be changed once a year or every 15k.

If I dont drive REALLY aggressive is it still ok to run RBF 600 cause I already bought it ?
