Brembo 4 –piston SRT8 brakes on RT – No Spindles Required

Knowing I would need more stopping power on my RT I picked up a set of used SRT8 brakes and rotors off eBay for $300. They came with the brakes lines but needed a rebuild. Rotors were ok but bought new pads, slotted rotors and a caliper rebuild kits for a little over $400.

Looking for any install tips I searched he forums and found that the consensus was that I needed SRT8 front and rear knuckles to install. Problem – new they are $700 each and used I found them for roughly $350 each. So that’s another $1400-$2800. Yikes !!!

Ok, if I have to but let me kook it over. So it turns out that the front calipers bolt up – issue is rotor dimension and spacing – they needed approximately .125-radius reduction and .250 spacer. Checked the pad sweep and guess what – it’s 14 inches – so I turned the rotor OD down to 14 inches and added machined a .250 spacer and viola – bolt-on.

The rears are more work. The rotor bolts on no machining required. The rear dust shield needs minor trimming. The caliper bolt pattern is different and needs an adapter. I trimmed the dust shield and made a.500 adapter and again- bolt-on.

Bottom line, total cost (minus my labor and machining) $700 and no knuckles required

could I give you a call? I want more info! Want to make sure I’m doing this correctly

What’s up y’all!!! I started my own DIY BBK because of this thread and it’s up there in one of my best mods. Way easier than ppl make it out to be.
NO SPINDLES REQUIRED.
I purchased a used front set of 4 piston brembos (2005-2014) for $200. I machine the rotor down from 14.3 to 13.9 (14.0 was BARELY making contact with the brake shims.) paid a machine shop $60.

Total came out to $260. $200 used brembos and $60 to machine the rotors. (Brought another set of rotors to the machine shop and he charged me $20)

added two washers on where the spindle/knuckle makes contact with the caliper (to center them perfectly with the rotor). Brembo Caliper bolts up exactly where the STOCK RT calipers would bolt up. Same brake line fitting.
VOILA!!!! See photos for the 4 piston brembos on a 5.7 RT Charger WITHOUT SPINDLES / KNUCKLES

This BR9 "Police Package" brakes sound like a great upgrade for an R/T.

So, just to be clear, is the BR9 a complete bolt on affair?
No spacers, No machining, No monkeying around?
Just buy BR9 calipers, pads and rotors?
Does this create any wheel fitment/interference issues after the fact?

Also, does anyone know if the brake master cylinder is the same? What about ABS tuning?

I looked into the BR9 and this route requires far less money, time, and parts. Literally used kit. Machined the rotor. Palaces two washers to space the caliper and voila

Not sure that the calipers are cheaper. I had maybe $150 in my used BR9 calipers and it was both front and back, including shipping.

Rotors are more money, no argument there. Not sure if they are $60 more, don’t remember. Could be they are not much more than what you had in yours after machining.

The BR9 has a different dust shield, but they are like $10 each. But it does require different front hoses so that adds to the cost where your setup used the existing hoses. One of the BR9 hoses was harder to source when I bought mine, I think all told both hoses were like $120.

So, maybe all told your kit was cheaper.

Thing I hate about machining a rotor is, you can’t just go buy another one and bolt it on. Long weekend at the road course several states away and cracked one of those rotors? Plan on spending a couple of extra days looking for and getting a rotor turned down again so you can drive home. Not knocking the idea, I just hate to have to modify wear parts to get them to fit, because it means I will have to do it every time I have to replace the part.

You’re right. I have a set of rotors on standby. I purchased power stop. For $160. Machine them down. The machine shop charging me $20-40 now because this would be my 3rd visit. I don’t know much about the BR9. Is that a dual piston like the OEM RT ones?

 

[Walter Andaluz]

They are.

Like I said I don’t know anything in the br9 but these brembos are 4 piston and so far so good. Never had br9 so can’t comment on them. Also I am boosted. I live in CA bumper to bumper traffic so I am very please with this kits outcome. Fingers crossed.
