 The pins, boots, and pad backs...  The pins, boots, and pad backs are thoroughly lubed and installed, and the brake lines are installed onto the new calipers and torqued to 23 lb-ft. The calipers are again mounted, and the last task is fully bleeding the brake system with Castrol LMA high-temp fluid, which exceeds DOT 4 specs. Finally! |  Problem: Worn skinny tires,...  Problem: Worn skinny tires, 16x8 rims
Solution: 275mm Nitto 555s, SLP 17x9 rims
The Z currently runs stock 16x8 rims with 245/50/16 Michelin Pilots that are seriously worn down. Time to add some grip in the form of Nitto rubber. The NT555s are an ultra-high-performance summer tire with 300 treadwear, A traction, and A temperature ratings. Nitto balances good grip with decent wear by combining a dry-traction compound with an optimized tread pattern, created to provide a large contact patch under braking, cornering, and accelerating. We'll be adding more grip by increasing tire size, as well: 275/40/17s will be at all four corners. You can grab the 555s for around $150 each. |  In order to mount those 17s,...  In order to mount those 17s, we picked up a set of SLP's 17x9 SS rims (PN 80041, $1,131). Not only will these five-spokes provide sharper handling over stock 16x8s, they are strong and look great in chrome; and they won't get bent out of shape after battling NYC's killer potholes. |

Brake Testing
I used Raceway Park's strip to perform brake testing with our Stalker radar gun. 100-0 and 60-0 testing was done separately, and multiple stops would be done for both. The final number is an average from all accurate runs.
| TEST | BASELINE | BREMBO ROTORS/PBR PADS | IMPROVEMENT |
| 60-0 | 144 FT | 124 FT | 20 FT |
| 100-0 | 436 FT | 411 FT | 25 FT |
