Wilwood Powerlite Rear Brake Kit for Porsche 914
Hey Teeners! PMB is proud to represent the entire line of Willwood products for all of our Porsche models but... look what we have here! An entire system designed for our awesome 914's. Most of our cars have a lot more power than they started with. To complement the added power, they need upgraded brakes and Wilwood Disc Brakes has come up with the perfect solution. You'll get forged aluminum Powerlite four piston calipers, brackets, and hubs, combined with larger, plain face or SRP drilled and slotted, "vented" rotors. That's right... finally vented rotors for your 914. Wilwood’s brake kit upgrade weighs ~53% less than our smaller OE cast iron, unvented brakes. Reduced unsprung rotating mass is always the right choice. Note: these brake kits MUST be used with a 914/6 or 911, 19mm master cylinder. Click Here for the Kit Brake kits feature:
Calipers: Powerlite (PL4R)
Rotors: Spec37 Plain or SRP Drilled & Slotted
Brake Pads: BP-10
Installation Parts:

Those are nice!
And ON SALE right now! 1500 OFF! Are those the calipers with the integral dust boots or the no-booted "Track" versions? Beautiful! |

What size are the pistons?
I would assume you should really upgrade both front and back to maintain the correct braking proportioning. |

Wilwood's radial mount calipers don't use dust boots. Many newer designs are (thankfully) forgoing the boot.
Here's a pic that shows the rear caliper and the pistons: ![]() Speaking of pistons, here's the rear specs... Piston 1 Bore (in): 1.00 Piston 2 Bore (in): 1.00 Piston Area (In²): 1.58 Piston Type: Stainless I would recommend you perform this modification as a "system". If that's not in the cards then I would begin with the "front" system only and then move to the rears. Putting this rear setup on your car without upgrading the front system is dangerous and not recommended. |

Wow!
Is 289mm x 20mm kind of small. I could not keep 911SC brakes from boiling fluid after a couple of sessions at the track ... even with brake cooling ducts. Are larger front rotors available? Thanks, Eddie914 |

Speaking of pistons, here's the rear specs... Piston 1 Bore (in): 1.00 Piston 2 Bore (in): 1.00 Piston Area (In²): 1.58 So this puts the Willwood between the 914/4 caliper with 33mm pistons and the 914/6 with 38mm pistons: 33mm 1.33sq in 2x1" 1.58sq in 38mm 1.76sq in increase the pistons to 1+1/16" to equal the 914/6 2x1.0625" 1.77sq in |
