Aftermarket front BBK comparison:
| RB 390mm BBK | MPP 400 mm BBK | Note | |
| Rotor size | 390x33 | 400x33 | |
| Rotro Design | Center mount | Surface mount | |
| Price | $1,799.00 | $1,690.00 | |
| Fits OE 19" wheels? | Yes | No | |
| Include brake pads? | Yes | No | ($320 value) |
| Rotor fits larger 65mm pad? | Yes | No | |
| Rear 390mm BBK | Yes (optional) | N/A | |
| Dust shield trimming | N/R | Yes |
Why 390mm BBK? because it's the most sensible, affordable and easiest BBK for Plaid brake upgrade. Just like installing the stock replacement rotors - No trimming or modifying the dust shield and no need to bleed the system.
Confirming front 390mm kit fits 19" OE wheel (test was done with 390mm CCB rotor).
The white light above the caliper is the clearance (about 3mm)
What the large (deeper) brake pads can do:
It has 65mm depth (vs. OE 47mm) which can help run the rotor much cooler than the stock set up under the same heat load.
Forum review between XT910 (Street) and XT970 (Track) compounds:
What can I expect from this kit in performance improvement and durability?.
Note: We recommend installing the complete rotor and pad kit to insure optimal results, no rotor or pad deduction available.
This kit is bundled with our best XT910 street performance pads & our lightweight two piece rotors, which can offer you multiple benefits, in addition to the substantial "unsprung weight", that makes your Plaid more agile and responsive and more efficient (more mileage for the same charge).
- Will not fade under spirited driving.
- Can deliver more consistent brake (friction) torque even under elevated temperatures, and give you peace of mind under high speeds or panic stopping situations.
- Excellent modulation - Very linear in brake control.
- Very low dust.
- No squeaking.
- Very durable - Highly resistant to wear.
