With the advent of forums and people with money and free time, people are lurk around seeking to be different from the normal crowd. They give new options for owners to upgrade parts not using aftermarket parts but using oem parts off of other car manufactures or type of vehicle or special edition vehicle. OEM parts are more accessible and can be easily serviced which is a huge advantage for any car owner. it brings down the cost factor which will help any car owner since their funds usually are always lacking.
i have researching alot about upgrading my brakes and came across an interesting fact that the Y33 suspension (infinit q45) has the same suspension setup as an s13/s14. in japan it is a common thing for them to swap out the whole suspension to s13/s14 (including knuckles) inorder to use s13/s14 coilovers, arms, and knuckles (they only change the top hats of the s13/s14 to the y33 top hat so they can simply bolt on.) in japan my big body luxury car is used as a VIP status vehicle displayed as trophy of authority and is also used as a drifting vehicle.
so i then searched for a while on s13/s14 brake upgrades … since ev erything is the same …
the options included using some cadilac ctv calipers, sentra calipers, z32 calipers, gtr calipers, s15 calipers, and two options of brembo calipers .. the evo8/9 and using newer subaru sti gold calipers … or i can do a full custom new brembo setup which costs as much as a motor swap ..
i chose the evo 8/9 brembo calipers since i had cheap access to them and it wasnt going to cost me alot.

they are bigger than the q45 calipers (for some s13/s14 owners the stock q45 calipers are a huge upgrade.) but they werent “attractive” in my opinion. the VIP needs both look and comfort ..
i could have chosen the sti gold brembo calipers … they are bolt on .. as well as the rear calipers are bolt on using a simple small spacer to get the exact fit (it has been done so many times now that the math has been done and rechecked.) but i had no access and i was unwilling to pay that much of money.
the evo8/9 brembo REAR calipers are completely useless!! .. no need for them unless u drill into them and tap into them … and do alot more bull shit .. it isnt worth it .. better off buying the sti gold brembo calipers … but instead i chose to do the z32 turbo caliper …
well while i am talking about not drilling and such … the evo front calipers are not bolt on .. NOOO .. they dont bolt on to your knuckle. you will need a bracket that will position the caliper correctly and make it work right.
so this is the bracket:


the bracket looks very simple but at the same time has taken alot of time to get the way it is. the bracket can be found at numerous places. i myself found a used set for sale on a forum. the price can range anywhere from $100.00 to $300.00 … so do you shopping ..
when i got my set .. they didnt come with bolts …
the bolt specs are:
from there u bolt them on to knuckle like this:

opposite side:

before you jump into doing this swap (it is very tempting .. i know) .. there are issues that come from it. the number one issue is the wheels used after the swap. first of all u will need a minimum of a 17″ rim (depending on barrel type.) as well as enough disc length to clear big calipers ..
