They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I run gen 3 viper calipers with 14.25 rotors and the cobra rear calipers with 11.75 rear rotors with Carbo tech pads, srf fluid and braided lines. Down the straight at 130 and braking with ease to turn one at Lime Rock. I watch others struggle to slow down. I couldn't be happier with these units. However, I'm using new Hydratech units in all my applications.

Does it stop? Yes. Do you have good pedal feel and feedback, no. So I do not like it. Dunno about Hydratech, but I am not spending the money to find out.

Poor pedal "feel" is usually a result of a single piston caliper giving an on/off type of feel. As you get into more advanced systems with multiple pistons, the feel becomes excellent. The systems we use are new and are time tested combinations.

I have 2 diesel pickups. One has a "traditional" vacuum booster, and the other has a hydroboost setup. I've never really been comfortable with the feel of the hydroboost truck. That said, I agree that this opinion is subjective. However, the vehicle in question will likely be OE calipers up front and and 11x2.5 drums out back... 2 Demons...no, not my kids!

If you don't have the vacuum to run the brakes properly, I'd investigate other means, like the electric assist unit. I haven't used them, but I know there are alternatives out there. Personally, I do not care for manual brakes.

Your preferred setup prices out kinda up there and then I still have to add P/S pump and such. I have a manual steering and manual brake car and I do not have a problem with that. As for the feel getting better with more pistons, how much more is that? $2-3000 to find out? They say there are no such thing as a stupid question.

It used all four corners of a 2005 Mercedes S55 brake system and a 1-1/8" D100 manual master cylinder. The pedal felt a little firmer than most power assisted systems but softer than the old factory manual brake cars/trucks I've had. When the pedal moved, the car slowed straight and true. Modulation was easy and drama free. We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon

The difference between stock disc/drum and modern brake systems is so dramatic they feel to me they have no brakes compared to my Dart. For instance, I drive a Magnum RT. Good size brakes for a regular car. Compared to the Dart they flat out suck.

Some aftermarket setups (like mine) need more boost due to smaller front piston area. Also may be a benefit with significantly larger than stock tire diameter which can reduce brake force.

I guess if I ever plan to hit the Silver State Challenge or try to beat my personal banzai run from San Diego to Tucson's time (4.5 hours to cover 400 miles) I don't need much bigger than I have.

I understand Peter to say that if you�re going to road race, you need a brake system to support that specific type of driving. I get that and I�m building as much braking capacity into my Duster that I can afford. I do want to be able to �haul down� from 120Mph+ as quickly as possible. An autocross cannot be compared to a road course; they are two different animals. Does everyone large need 4-wheel disc brakes and a hydro-boost? No they don�t, pick what works for your style of driving. 1971 6.1 Gen III Hemi Duster
