PoPo's were nothing exotic... But offered some neat goodies.
- Break cooling ducts in the front bumper to cool front breaks.
- Engine oil cooling system which pumped engine oil into the rad, was standard option until 2004.
- Heavy duty front and rear sway bars which was offered on the 300M Special.
- Struts/Springs were much more firm for more performance.
- Alternator offered higher output.
- Bunch of cosmetic things like rubber floors and rear seats, disconnected rear door handles, trunk mat, etc.
- Special EL cluster
- Possibly higher tuned PCM speed governor - not sure on this one.
The Journey's knuckle is different on the bottom, doesn't seem to have a tension rod/strut/bar. Otherwise top portion is identical. The knuckle doesn't have the pad bars either. Not an issue when using different calipers though.
LX platform knuckles are completely bizarre as far as LH similarities are concerned as well.
It's all going to come down to this, no matter what breaks we choose to use, either it be OEM standard or Brembo options or aftermarket Willwood and other premium brands, we need the adapter bracket.
Which isn't hard though. Get a chunk of steel, measure out the caliper mount positions and the LH knuckle bolt locations. Mill one out and bolt it up to see where it all plays out.
I'd pay $$ for a set of brackets. Look at these brackets for a Willwood set for the LX platform. Options are limited as far as the bolt pattern of the rotors.
