How low before I need to relocate bumper tab?

[charlie15]

Hey guys want to lower my car on some swift spec r springs and don't want it too low maybe Bout an inch lower. My rears from memory are 17x9 +47. Will I need to relocate my bumper tab to avoid any interference?

I've tried a search but couldn't find anything.

Thanks heaps

I have to tell you that you need to trim the bumper and relocate it with these rims & tyres

here is the link to help you DIY
Just trim the bumper a little bit and then relocate, if it still rubs, trim a bit more, that's how I didnt mine. Dont forget to adjust your camber before you doing this
