Default LX570 BBK Install

Well, the wife warped the rotors on the LX, so I went both feet in with the 380mm 6pot/4pot front/rear kit from SOS Performance - also sprung for the 2 piece rotors up front. Surprisingly, the price from SOS was better than I could get thru turn14 directly from StopTech (
via my brother's shop).

Sucky stock potato-chip brakes:


Of course the stock rotor was rust welded to the hub, so m8 bolt to the rescue:

I'm here for the gang bang:

New bracket on with some torque paint - so I don't have to check it all the time with a torque wrench, the paint blob will break off/crack if it starts coming loose - plus it's a nice fluorescent yellow color so easy to spot:

Huge red 6pots, what else is there to say:


And driver's front all buttoned up:

Time for the Saudi F1 race, so I'll finish up the other side this afternoon and get some pics with the wheels on.

The rears are likely a next-weekend-problem, but I'll update the thread further when I get those done.

Alright front is all done now:

Pressure bleeding:

And pads all bedded in - the different is amazing, worth every penny; and the rear brakes aren't even in yet!

it is always fun to work on brakes, easy, but not too easy that you do not have to work on it

Those look killer! Great stuff. Looking forward to seeing the rears installed.

Is there a decent pad selection available for those calipers?

Yea, these are the StopTech ST60 calipers, so there are tons of pad brands and compounds to pick from. I went with the least aggressive pads from SOS Performance (Hawk HB122Z.710 Performance Ceramic) so I didn't have to deal with a ton of brake dust and squealing, which my wife would undoubtedly complain about. The same is true for the rears, which are ST41 calipers I believe.

Ok got the rear kit buttoned up this evening.

Trimmed the rear dust shields with an air nibbler:



Brackets installed (there are also bushings that get installed in the hub, the factory rear calipers are M14 mounting bolts and these are M12):


Calipers installed and rear lines bled:

Note that a spacer is required in the rear - technically the 21" rims fit and clear the rear calipers, but it is mighty close and any deflection in the rim would destroy the rear caliper.

Will follow up once I get the header install finished and put some more miles on the truck.

Wrapped up the header project finally so I could get the truck off the lift and put a few miles on the rear brakes - it was already awesome with just the 6pots up front but it's even better now - less nose dive under heavy braking and the balance is perfect. SOS Performance is awesome (https://sosperformance.com/) and the kit was worth every penny!

Looks great! Amazing how small 380mm looks behind those 21" wheels!

Very sharp looking. so essentially a direct replacement? no other issues with fitment from OEM other than the dust cover "modification"?
thanks

Yes sir, the only permanent modification was the dust shield.

Looks great. Thanks for sharing. Noted the rear spacer recommendation. Time for me to go and warp the wife's rotors to justify this kit.

More pics if you have some
