I'm pretty much stock on 17x9.5 ZR1s w/ 275/40/17's.

Anyway, I've got some Hooker supercomp LT's for it and I want to lower it, so will the pro kit make it too low with the headers? It's my daily driver, for now.

 

I think you will definitely scrape it you hit the right incline or pothole.

 

you might hit the longtubes if you go into steep inclines,driveways, etc. Im at stock ride height right now and I have Pacesetter LTs. Have not bottomed out on the headers yet, but I bottom out on the air deflector sometimes. If you are worried about scrapin the headers, dont go on any crappy roads, and if you have scraped the air deflector before, avoid that place, or go really slow and at an angle.

 

I got LTs from pacesetter and when i lowered my car exactly 1" front 1.5" rear i started scrapping everywhere, on the headers. I've got u-bolt clamps holding it together that have loads of scrape marks on them, but the headers still look ok. When it scrapes the headers are touching the body so you can feel it through the whole car when you hit.. i'm worried i'm going to bust the header bolts outa the heads it hits so hard sometimes.

I do have the stock salad shooters.. 245/45 R16
