So this is kinda liek a big brake kit but you mantain your factory calipers. It comes with a caliper relocation kit and oversized rotors. The front stock rotors measure in at 10.76 inches and the powerslot plus come in at 12.8 inches. The rears are 10.5 inches and the powerslot plus come in at 12.53 inches. The rotor is a one piece with a two-piece look with a black cadmium finish. Found we can get the fronts for $572 and the rears for $354. I dont know if anyone has looked at these or used these on any cars, but if you have any input please let me know. I also talked to one of the reps at powerslot and he said the stock 17 inch rims would fit no problem.

 

I think if I wasn't going to get direct replacement rotors (same size) and was actually going to increase my rotor size, I'd just go for a BBK and get better calipers too. Just logical to me. Not that it would be bad to use the stock calipers, but if I'm going to go for a larger rotor with more surface area, I'd want some more clamping power for it too. That's just how I look at it, I don't know how much it actually matters.

 

increasing brake rotor size does not improve braking. the increase in size also increases weight of rotational mass and unsprung weight which will result in slower acceleration, longer braking distance, and less responsive handling because of the weight difference.

unsprung weight is weight of the car that isn't controlled by the cars suspension. this weight is mostely made up of wheels, tires, and brake rotors. increasing this weight will reduce handling response.

rotational mass is the weight of the moving parts of the car that move. the wheels, tires and rotors, the heavier they are, the more effort it will take the engine just to overcome the greater inertia of these bigger parts. it will also mean more work for your brakes to stop the car.

the only benefit of larger rotors is that they have a larger heat capacity and resist heat fade better.

just upgrade to slotted rotors and high performance pads like the dezod motorsports package or the stoptech stage 2 upgrade kit.

big brake kits are overkill unless you plan on putting your car through alot of track time and hot laps. not for a daily driver.

 

The price and looks is what makes me want to get these. Instead of spending over a grand for just front BBK I could get all four. Plus how much of a difference is a BBK going to be rather then new larger rotors and say Dezod brake pads. The pros weigh out the cons to me. If I were to go with a four piston caliper I would figure it would have a more even distribution on the rotor but have the same clamping force.

 

ahhh i didnt think of rotational mass. Well to do BBK your gonna need some light weight wheels. Awesome point drax

 

That fronts for $572 and the rears for $354 price is scare

 

There are quite a few people here that have them on the rear to match front BBK, but i don't know anyone that's running them on all four corners. The problem with the PowerSlot Plus is that they are one-piece iron rotors which makes them twice as heavy than stock; you'll gain heat capacity, but you'll lose stopping distance because of weight and a lack of pad/piston surface.

As Drax said, it's better to buy slotted OEM-sized rotors and upgrade your pads, otherwise you're just paying for looks and decreased performance.

 

looks like i will being going with some rotora... or should i do powerslot. lol i hate to ask it.

 

stick with the same rotor size but get some performance style rotors. I have a set and I love them , they cost about $160 and they are worth it for the job it does. The tC does not weight that much so if you arent going 100mph runs or autocross then its really pointless to get a BBK.

 

good point guys, will probably just order same size rotors from rotora and have them zinc plate it.

 

yes, they should do you just fine. i got mine at a good price, I had a guy on ScionSmoke.com give me a good deal on them

 

I have wilwood fronts with powerslot rears. They made a HUGE improvment in brake balance with the wilwoods up front. Very happy with them.

 

rotora.... powerslot.... now wilwood! where did you get the wilwood?

 

From wilwood

 

very true, tires are going to be a best bet for shorter stopping distences. Also, StopTech is coming out with a Ceramic BBK that will be lighter than our stock set-ups... that would be something worth upgrading for. Prob cost a pretty penney though...LMAO

 

i have the powerslot plus kit front and rear. its definitely a show mod. the rest of my brake components are stock, so I havent noticed an improvement in braking. the front rotors are 2 piece, and the rears are 1 piece. the black coating wears off to reveal silver underneath (like all other anti-rust coated rotors).

also consider the cost of eventually replacing the powerslot plus rotors (or any rotor from a BBK). MSRP for 1 front powerslot plus rotor is around $325 each.

 

Ouch... the wilwoods runs about $1050 shipped and there is a MASSIVE improvement in pedal feel / stopping distance. Especially with the 235 azenis tires I am running. Stopping power must be complimented by grip.

 

They are two piece rotors too correct? You didn't happen to weight them did you?

 

Yeah I did and took photos on the scale. They are just under 13" and weigh exactly the same as oem, 14 lbs.
