Whats up everyone! I have not been on here in quite a while so its good to be back. I have two questions.

1- there is this thud sound that sounds like its something bouncing around in the trunk but its not. I assume its a suspension issue. I am lowered on BC coils, any ideas?

2- I am ordering Forgestar F14F wheels soon and Im trying to decide on sizing. Im going to do 19x10 +15 in the back and 19x8.5 in the front but dont know what offset to go with. And because I have the x need to figure out which tires to go with for the right amount of stretch and function.

thanks!

 

Are you going for function first, or form? +15 is pretty aggressive on a sedan, needing quite a bit of camber and a decent amount of drop.

Look at the photos of my old Rennen's here:

The fronts are 8.5 +24, rears (in the first post photos) are 10.5 +35 (later on replaced with +45s to address the rubbing). The rears on those rub with 285 rubbers. Camber was roughly -1.9(f) and -2.3(r).

Your x10+15 in the rears would extend and extra 15mm.

About that thud, not sure there. I have BC's myself, but no issues *knock on wood*. How stiff do you have things set? Are you sure it's not a loose spare tire, or the manual bags jumping around back there?

 

the thud noise is something under my car or in the suspension im pretty sure. I currently at 15 in the front and back. With the new rims Im planning on tucking tire and resting at the lip. I also want function though, no more than -3.5 camber all around. I will definitely be stretching tires to make them fit but dont want to go to crazy here. I have seen people do 9.5+15 in the back no problem and I have seen people do 10.5+15 in the back but thats a bit to much. for the front I have seen people do 9.5+15 which I though was no aggressive enough so I figured with a 8.5 I should be around +5 or +7. thoughts?

 

Can anyone chime in on this? Still trying to get opinions.
