Big Brake kit.

I have now driven them for about 30 minutes. Suburban and a bit of highway driving. Definitely a very different feel, the power band in terms of felt force comes on earlier, likely due to the larger counter torque from the larger disc.
Haven't done any hard braking. Following the advice from the manufacturer.

I use SRF racing fluid. I think it's superior up until about -30. Below that temperature I think conventional fluid is pretty good. I just don't drive in that cold weather.

I like that fluid as well in my go fast car.

Mass times velocity = momentum is a great formula.
My viper is heavy on the velocity side of the equation
The Grenadier wins on the mass side

Either way the srf fluid is great for handling high momentum vehicles.
