Looking for upgrade on street driving, towing, racing?
If just street then you could up your game on the pads. Any other 'upgrades' you're talking about a brake kit, then you're talking a huge upgrade.
Do you have the street pack with the upgraded pads and wheels? Don't know if your'e going to see much of a diff to matter without goin for a full conversion. Again depends on what wheel and brake package you have.
