Im looking to buy rpf-1s in 17x9 +45 with 225/45 front tires and 255/40 rears. My fenders are rolled and rear bumper tabs are relocated, and i plan to buy Tein S-tech springs. I do not want to run negative camber. Would this setup work with no rubbing? Could i possibly go with a lower drop than what the S-techs offer? Thanks for any advice.

 

If you're already rolled then you should be okay, and yes the s-techs should be fine as well.

 

would i possibly be able to go lower though? i was also looking at skunk2 springs which advertise a 2" drop...

 

It's relative to your roll at that point...do you have a mild or aggressive roll? You could always use a caliper and measure your clearance. That would be the best determination. I personally think you would be fine, but I'm speculating.

 

All 4 corners have the lips rolled completely flat, but I haven't pulled them and don't plan on it.

 

you are more than likely going to have to run a small bit of negative camber if you go lower.

 

You will be fine. But just realize that unless you get aftermarket camber correction of some sort, you will be running -camber. The lower you go, the less adjustment you will have to offset this. Dropping 2" you might be running UK spec camber alignment best case scenario. If you drop more then that your not going to be happy, -3 +

But as for clearance, no problem.

 

Okay so what you're saying is just by putting lowering springs on it will change my camber?

 

Yes. If you put the springs on you'll need to get an alignment done.
