turbo/4WD GTi-R brakes

hi i am planning to put the GTi-R brakes on my micra, after i source a super s rear axle. will i need a bigger brake booster? if so is there one for an easy conversion.

thanks for your help

There has been a lot of previous discussion about fitting AD22VF calipers from GTiR, Pulsar SSS etc.

There are some basic comments here: http://www.micra.com.au/technical-articles/factory-bolt-ons.php

If you want even bigger, how about the calipers on the 3rd post down here: http://www.micra.com.au/community/message.php?messageid=29282

to fit anything bigger then the gtir calipers you will need the stub axles from a jdm k11 or sum custom brackets, as they are different. 2nd. no you dont need a bigger booster if you do the rear disc conversion and gtir front calipers. if your going to use a bigger one, modify a rnn14 one to fit into the k11. dont skimp out on the gtir brake upgrade either. use new pads, and new discs. rda/ebc make some good shit, and is very reasonably priced as opposed to dba/etc.

What exactly is different between the UK & JDM stub axles?

the brake caliper hole spacing

I wouldn't be surprised if the 1L & 1.3L JDM cars are a different size as well.
Anybody got some measurements?

yeah. probably are. i bought a half cut a while back .. was a jdm one. and the spacings were different..

the primera gt brakes are 280mmm diameter by 22mm thick and they should bolt straight on ( at least i hope they will as i have a set coming for mine! )
