P&L STI Lightweight rear brake kit

Thinking of whether to try this out. I know it says drag/auto cross only. But dem weight savings.

And how much to the rear brakes do anyway? Naff all thats how much. TRD pads in my rear poo spec brakes (base model outside US) were engaging ABS before my Wilwood Front BBK. Admitidly I had stock suspension in, so rear was getting massive unloading. But still. Has me thinking about running these brakes.

I can not determine from their picture if there is a parking brake surface inside the hat.
From their website:
"While this kit is “street-able” we strongly do not recommend using it for daily/street driving. The reduced weight also provides for less thermal mass for heat dispensation and therefore is not good for extended braking applications like a PDX/Track Days, or Daily Driving." (My italics)
I think the application is very limited.

Yes saw that, although imagine that is for an sti, the 86 is much lighter, so not as demanding on the brakes.

Hand brake?

I don't think it has one. Could live without for dat weight savings

I'd say call them monday at the shop unless you were trying to take advantage of the black friday sale.

Forty lb reduction just for rear kit or coupled with front kit? I would think the latter, but it is vague.

The rear brakes have a large iron drum brake surface inside. 40 pounds is probably just from the rear. I sent p&l an email a week or so ago about this kit. More specifically whether a slightly larger rotor would fit their bracket. Wilwood makes the same rotor with a .81 clearance which would be able to take a normal vented rotor. The weight savings would still be significant. Haven't heard anything back.

Robispec runs ultra light front and rear brakes. It accelerated well for a N/A but yielded no additional benefits for track use. With that said, not sure what you are trying to accomplish. Do you want to have the ability to trail brake? As preference, we use non-staggered brake compound to get our desired braking performance.

They were closed most of last week for thanksgiving. If you havent heard back, call them (847) 678-4311

I wouldn't risk safety for the weight savings. The rotor seems like the same size as stock but only 1 layer vs 2 for the oem ventilated disk. I don't think the rotors can take the thermal abuse of daily driving, not to mention the pad size is also smaller than oem. You'll just cook them, I think.

No parking brake is a bigger issue on a street car then you may think. The handle in my daily won't lock currently and I haven't had the time to fix it. I keep waiting to walk out and find my car down the street crashed into somebody else. It might not be an actual issue, but it sure makes you nervous on a daily basis.

You could likely add a hydraulic handbrake with a lock to get all the weight loss (except for the parking brake handle) and none of the downfalls of no parking brake.

I dont see any reason to put this on your car..OP what reason are you considering using this for?

What kind of daily driving do you do? Come on people... this will hold up just fine for commuting and the stopping power won't be any different. You don't need a parking brake if you leave the car in the proper gear and if you're real paranoid, there are other ways to have a parking brake.

The big compromise is that you won't have an e-brake which is there for a reason and the thermal capacity will be reduced for heavy use. Track days or a run through the mountains. Things like that which is why I'd like to retain a thicker vented rotor.

The reason you'd want to do this is to drop a large amount of rotating and/or unsprung weight. People pay the same price to drop 10 pounds from the driveshaft. This kit drops 4x that weight, some of it unsprung as well as rotating. It's also further away from the center of the car which makes the weight more significant.
