i have 94wrx wagon, want to switch to some 4pots calipers from the later classic, is it just a straight off on job. Do I need to change my discs to adapt to 4pots if so which ones?

 

straight swap,discs are 294mm i think,pads are different as well

 

so i have to change my discs to 294 from 277?

 

yep, fit as a matching set of discs & pads............just be aware that there can be issues with wheel clearance on certain models

I had to change my 16" wheels for late model impreza wheels (the 5 spoke design) as the spokes of my old 16s rubbed on the calipers.

 

im pretty much in the same bag, got a 98 type r import. 315 bhp and the disks and pads have just about had it so im looking for a replacment without going for bigger wheels. got 16s. got around 500 quid to play with and am planning to do th odd track day in the future.

AP 4 pots/300mm can be found 2nd hand for not much more than that, alternatively look out for STi Brembos but I don't know for sure that they are ok with 16s, someone else might confirm?

 

I've got some for sale here £200:

The STI Brembos will not fit under 16" wheels you will need 17" and the offset has to be big enough to clear them too.

 

was thinking about just upgrading the disks and pads and putting on some steel braided hoses... grooved, drilled or just a better standard of ready salted??? lol.. im trying to limit my mods... already spent 7 grand on engine re-build, new ecu, front mount intercooler and recently 1400 on a bloody head gasket (man hours + parts). so this is the last thing i want to do to it for a while. more 'pots' means bigger wheels,tyres etc.

any ideas???

 

4 pots if you can afford them, easily get calipers, discs and pads for approx £300-350, plus braided lines (£60-70) and decent brake fluid

or

decent pads, ferodo, pagid, ebc, etc etc. Decent discs, grooved or smooth - drilled have a nasty habit of cracking and once again braided lines and brake fluid

your choice of tyres will also have a big effect on your braking ability

hope that helps a little

 

yeah ive got subaru 4 pots.. so looks like just upgrading to grooved disks some better pads and braided hoses. any subaru specialists around the chatham area???? looking for somewhere to get a sticker number plate, moving mine as its blocking air flow to the fm intercooler. goona place it on the front splitter,
cheers

 

As I have just found though, the normal AP bell/disk for their 304mm Formula kit is rare and expensive, due to the bell/disk PCD.

Having written that, there are companies that will supply replacement rotors much cheaper. And getting hold of decent AP radial mount calipers is worth the dosh in the first place.
