?Questions About?- Corksport Rear Big Brake Kit
I've searched around quite a bit but haven't found any first hand info regarding this set up. Who here has this brake conversion on their car? How many miles has it been used? Likes/dislikes? What exactly is included? (the online instructions are a little vague) Any pit-falls to watch out for?

Why would be my question? These cars are already overly rear-biased stock. If you want big brakes, the front is the end that needs it. And there, the stock brakes with FD rotors (FD's used the same four-piston front calipers as GXLs/Sport/GTUs/vert/TIIs), with adapters to move the caliper outwards for the larger FD rotor, and you have more effective front brakes that will probably actually be proportionate to the rears, helping to avoid the premature rear lockup that wants to put these cars in the weeds.

UMMMMMM what? I can tell you with certainty that they do not focus on larger rear brakes. Look at every race car in the world, the fronts will be larger than the rear, even in a mid/rear engined car. If you have leger rear brakes, the car will have a tendency to want to slide sideways under heavy breaking, very similar to just ripping the e-brake. Most cars will have a pretty neutural setup though between front/rear though.

im not talking about every race car in the world, im talking about rx7s
they seem to focus more on larger rear rotors, ask them not me. Search for the people who made their own rear big brake kit, nothing for the fronts and those guys track their cars not just talk about it like we are so I will take their word for it

Since the prop valve is only a "reduction" valve- it can't increase clamping force- a larger rotor/caliper is needed so you start with "too much" and then reduce to "just right".
The penalty for this extra adjustment headroom is weight but I'd imagine that any serious race effort would evaluate the setup after sufficient data acquisition and make hardware changes as necessary.

looking around guys who really track their cars end up doing both, but for most people just larger rears are all they bother with.
lots of liability issues involved with modifying your stock brakes which seems like the reason no one wants to bother with a kit, then when they do someone comes along and says they can make the brackets for $50 and **** on the companies putting the R&D into it

Wow, this quickly turned into another debate thread. Can we please keep it to usefull info about this specific conversion.
Is there anyone out there who is using this kit.

Top Secret.......I could tell you, but then you would disappear without a trace.
haha!
Seriously, this isn't a major mystery........To compensate for larger FRONT brakes.

Well the car really doesn't need it. It is nice and does help, but think about the weight distribution. The reason the car has the larger brakes in the front is because its heavier in ths front and has more momentum to shave off.
I would say just go with it if you want. What will it hurt?

Is this the kit you are talking about? http://www.corksport.com/corksport-r...grade-kit.html
Because all this appears to be is larger rotors, because the clamping will be in the exact same spot the only thing you will gain is slightly less braking performance because the disk itself is more massive but the disc will be cooler longer and be more resistant to overheating. Unless they actually give you new caliper mounting brackets as well, the kit or instructions don't say.
Why not just put in more aggressive pads in the rear if you are that concerned? A lot cheaper.

Typical FC owner: dude I just re-did my whole suspension and wheel setup! It was like $6k but at least I got everything done, even some new rotors and pads.
Typical FD owner: dude I just re-did my brakes because I'll be hitting the track soon. So I decided to go with that new ENDLESS BBK setup. Was like $6.5k. Good value I'd say.
FC is the poor mans Porsche, and it's just a fact of life haha.

If it utilizes caliper relocation brackets, then the kit does have a mechanical advantage (increased leverage, extra rotor mass for cooler temps) over the stock rear brakes. But if it is in fact just larger rotors, then it's a cosmetic upgrade only and won't fulfill my needs. This is why I was hoping to find someone who has this kit already.
If I can get better rear brake performance for a reasonable price, and it closley matches the performance increase from my front BBK, why wouldn't I spend the $334?
Isn't there someone on the forums affiliated with Corksport? Cant remember the SN.

Why wouldn't you spend like..$120? There's so many types of brake pads out there it isn't funny. You could also use a street pad in town and then switch to a track pad when you need it. Or if you already have track pads in them then you can go to a more aggressive rear pad then what you have in the fronts.

Yes, that is the kit I'm talking about. And yes, the description and instructions are vague as I mentioned in my OP.

But if it is in fact just larger rotors, then it's a cosmetic upgrade only and won't fulfill my needs. This is why I was hoping to find someone who has this kit already.

the install sheets dont show a relocation bracket, it actually advises you to do some grinding.

But for you I suggest:
http://www.ebay.com/itm/NEW-BIG-FRON...item3cc0882834
Or just get steelies and some bling hub caps so you don't have to see the rotors.
Or just buy a car from 2012.
