I've been searching for the past couple hours on whether or not I have all the necessary hardware for my kit on my 2011 WRX. I got my kit with the calipers, stoptech slotted rotors, and stoptech pads from MACH V. For the rears it did not come with the pad guide plates... Here is what it came with... Here is where I believe they should go... I know the stoptech pads don't need the shims. I found a thread talking about the guides but I'm unsure if they're talking about the same part or not. http://forums.nasioc.com/forums/show....php?t=2217647 For the front it didn't come with the spacers. Again I know I don't need the shims for the stoptech pads but can I run without the spacers up front? The front only came with the pins, pin spring, and the cross clip. So the question is can I run without the rear guides and front spacers?

Spoke to Dan from Mach V today. He said he believes what I received is the whole kit, everything needed for installation. He thought maybe the guides were installed on the caliper already (they are not) but he said the kit I received is what they install on a daily basis. I put the rest of the calipers together tonight and have one installed on the car so far.

I will report back with how everything goes once the installation is complete.

Anybody else have any thoughts?

my thoughts are... they're installed correctly but you don't actually need them. In fact they're harming your cooling a little.

I was actually working out this problem myself about a week ago. Here's some reference from STI's companion paperwork for the FIA VO:





My understanding is that the rear kit *should* come with the guide plates, but if not, there are two p/n there on the list for you. The front, however, does not appear to utilize the tiny little brackets. They may have been a later addition for noise reasons? Subaru shuffled a LOT of little things around trying to address brake and drivetrain noise on the GD models. The instructions also recommend using an early ('02 WRX) prop. valve p/n 27671FE010 to address the rearward bias and lack of EBD if you remove ABS.

Judging by your pictures, you are missing both the upper and lower spacers (2 total per side) as well as the inner and outer pad shims (4 total per side).

It looks like you're right they definitely have all different parts for different years I guess. I'm not sure what year the Rallispec kit's diagram is for but according to that I'm missing the top and bottom guide plate for the rears (2 per caliper) and the lower spacers for the front (2 per caliper as well)

I spoke to Dan from Mach V again on Thursday and he said he spoke to the techs and they've never installed any of the parts that I'm missing. He sent me this diagram



That gave me enough confidence to get them on and just see what happens. Finished the install Thursday night, went for a test drive and bedded in the pads. Everything worked great! No squealing, creaking, or grinding or anything! Also yes I did not have the pad shims or backing plates either. According to everything I read about stoptech pads indicates that they do not require them.

This is the second day I've had the brakes on and the pedal feel is amazing. The only brake work I've ever done is pad swaps so to say I was intimidated with this install is an understatement. Once I got past the hardware worries my biggest fear was the bleeding process. I used a harbor freight vacuum pump, I was never able to get an absolute clear stream, there were still a few small bubbles but I read that could have been due to just the threads. All I can say is the pedal pumped right back up after I was finished and it's super stiff now giggity!

All I can say is Google is your friend when it comes to this install, ALMOST all of the info is out there if you look hard enough. Thankfully this board is here for what isnt,

Thanks guys!

In the rear I suggest you need the guide plates. They protect the AL caliper from the steel pad backing plate. (Brembo's have this plate attached w/ a screw and pretty much every AL caliper I have used has some version of this). Also - those plates take up some space so you may get some rattle without them.

In the front - my 06 WRX came with all those corner pieces on the pads. The caliper is iron so it does not need abutment plates and the corner pieces are more likely only for noise/rattle.

We sell the rears with - the fronts without.

Hey Ken thanks for the reply.

Yeah it looks like everybody sells their kits differently when it comes to this hardware. I feel as if over the tons of threads that I read while I was searching for an answer I came across a post from you that stated that same exact thing too. The guides save the AL caliper from the steel plates.

I think I will probably end up ordering a set but just like you said I think I will leave out the front spacers. Oddly enough I haven't had any noises yet from the brakes. I kinda figured I would too because just like you said there's a serious gap without those guides. Yeah I will definitely be ordering a set. Thanks!

That diagram is mislabeled - it is a picture of rear Brembo calipers that should be labeled "REAR DISC BRAKE 17INCH '04MY-'06MY". The quick giveaway is the harmonic damping weight, though there are other obvious details.
