GR Corolla 23+ to 25+ Bumper Conversion

This writeup is mostly just the required parts list right now. More installation details to come when resources permit. You will also need some miscellaneous hardware (self tapping screws, pop rivets etc), some recommendations are listed at the bottom of the page. 

 

Factory cooler shrouds or brake ducts have not been fit checked yet. 

 

25+ Toyota Parts Diagram

You can just leave the 23+ fog harnesses unplugged, they will not throw a code or cause hyper blinking. 

 

Core USDM Models have matte black parts and those are a little bit cheaper. Premium and higher trims are gloss black. The matte black / core pieces do not have parking proximity sensors, the gloss black pieces do. The bumper extension (cooler side vents) come paint matched from factory which is a nice touch, just choose the correct suffix. 

 

Huge shoutout to a valued customer Will Mannella for helping with this and our local Toyota Parts Department for putting up with our scavenger hunt.
