Ok, so since this is something that’s becoming ever more popular, I decided to compile all of the information you need to upgrade the front brakes on your 5th gen to the 6th gen brakes with 12.6″ rotors…
First check your wheel clearance to make sure you have enough room for the brakes to fit. Measure from the center of your wheel to the inside of it, and if you don’t have at LEAST 7 5/8″ these brakes will not fit on your car…they do fit the 5.5 gen 17″ SE wheels like a glove, but they don’t fit with the 5.0 gen SE 17s…
f you do have enough clearance, the next step is to purchase what you need for the upgrade. Here are the things you need to get your hands on:
- 6th gen calipers (I bought mine from Dave B. for ~$60 each)
- 6th gen 12.6″ rotors (I bought mine from automax’s GD; brembo blanks for ~$100 shipped)
- 6th gen front brake pads (Also bought from automax’s GD; PBR metal masters for ~$50 shipped)
- 6th gen front brake shim kit (got mine from Dave B. I think for under $20)
- Brake fluid of your choice
These are DIRECT BOLT-ON for ALL 5th gens (5.0 and 5.5 alike) but you can also opt to get Matt Blehm’s relocation bracket on the 5.0 gen (but not the 5.5 gen) and use your stock calipers.
Installation for me would have gone smooth if I had a right and a left caliper, but I accidentally got 2 left ones! DOH! Make sure when installing the calipers that the bleed screw is on TOP. (shown in the picture below.)
For me, the pedal feel was GREATLY improved (although this may be because I was running on my stock brakes at 50k). The pedal feels firm, and even after beating the sh!t out of my car at MSR during Maxus, I didn’t get an ounce of brake fade with my ATE Super Blue Dot 4 fluid.
I bed the brakes in just after installation and so far no abnormal noises or vibrations. There is great feedback from the brakes and they don’t seem to lock up under extreme braking as they did before.
From a performance point of view, I could not tell any difference in acceleration. These rotors did feel really heavy, but IIRC they are only 5 or 6 lbs. heavier than stock, which also felt really heavy, so it would be pretty hard to feel any adverse effects on acceleration.
As for the paint on my calipers, I used the G2 silver paint kit. I applied the paint only where you could see the caliper from the outside, and I applied 3 coats with much more paint to spare. The decals are just stick on (I put a couple of coats of clear over it just to make sure they would stay).
Any other useful information is welcome, as I believe this is all I have. Good luck to anyone that attempts it, and in my eyes, it was a very worthwhile mod.
