Hey guys.

 

Been thinking for a while about upgrading my stock Liberty calipers to some WRX 4 pots front and 2 pots rear. Like the ones pictured below.

Mainly looking for advice as to how easy/hard the installation might be. Main questions are:

  • Is it a fairly straight swap?
  • Do they need a different mounting plate?
  • Does my ABS module or brake booster need any tweaks to match the new calipers?
  • What other issues may I run into?

Hopefully I can get some advice and figure out whether it's worth it or not.

 

Thanks fellas.

I'd be surprised if there isn't a DIY on this. Search the forum thoroughly.

You may need adapters for the rear, but it should be an easy swap, just check your rotor width. But that said most 4pots come with rotors these days.

Maybe upgrade brake fluid aswell, and check your lines in the process to see if they need an update.

A Gen 3 guy will be along shortly to add more info.

1. Yes
2. Rears need adaptor dog bones or S401 rear hubs. Considering theres only 290 s401s made, get dogbones

3. Nope

4. Putting the calipers on upside down and not bleeding them properly. Wheel clearance

Awesome to get some feedback. Might be a while before I attempt it but it's good knowing that it's a fairly easy straight swap.
