I have a set of four Enkei RPF1 rims.
But I wonder what I have to do to get this on my vehicle without hitting the fenders with the wheels!
Someone that has these dimensions on their Civic's?

ET 38 - 4x100 - 16x8

 

You're going to have to run a thinner tire and camber your wheels in with a camber kit or raise your car. I'm an EK owner, so I don't know much about EGs. Measure the diameter of your stock wheels with the tires on...now go measure your RPF1 wheels and see how much more width of tire you can add on and pick your tire choice accordingly. If you don't know how to size tires, there are plenty of sites that can teach you. You want the entire diameter of your wheel set up to be close to stock or sit close to stock as possible...so pay attention to the aspect ratio and get the proper sidewall width. I'm not sure what the lowest offset range is for an EG, but 38 should fit with no issues on an EK with the proper tire and drop.

 

I was told I can use 205 on them to make them camber in a bit.
I will also "remove" the thin edge inside the fender, I think that will be enough with a bit camber, and some serious lowering!

 

you're going to need to run a 195/40. And just fyi the tire size does nothing to make you tire camber in more. I have 16x8 on rear and 16x7 on front with ET of +24. My rears are rolled and its a tight squeeze but it works. Not too sure how the wheel wells are on an EG though.
