hi
im new o this forum/ i have an09 impreza that im installing a4" subbie lift oz kit with coil overs and 15" wheels
want to know what might be my best option for brakes upgrade

 

Best option is to change brain first.

 

what do you mean?

 

assuming youre going smaller wheels with chunky tyres? just stick with 16" and use the OE caliper/disc setup. 4" will look too high though - and if doing so then diff between a 15 & 16 wheel is minimal in terms of asthetics

plenty of examples on your side of the pond of it on - and probably worth while asking on https://forums.nasioc.com/

lift kits arent big thing over here

 

change it and You will know

 

Ignore him, he's an unpleasant troll. He's a waste of space on other forums too.

I think you'll always struggle to get reasonable brakes under 15" rims although some gravel spec options I believe do fit over the stock 4 pots. Very few though and what's available is likely to be expensive.
