Im looking at putting some 17 inch wheels on my car and i
cant decide on widths and profiles. My choice so far is
215/45/17 on the front and 225/45/17 on the back. and also
what offset on the wheels should i have for 17x7.5?

I have Enkei 17x7 with a 42 degree offset...this is pretty much for a front wheel drive car, but they fit real nice and I have 215/45/17 all around.

You can stagger but why if a daily driver?...nice to be able to rotate and extend the life of your tread. I have my race set on my stock 15", and my next tread I am stepping up to 225/45/17 all around, you'll be happy with that.

Offset, try to find a 35-38 degree offset, you can go 40, I am pushing it with the 42, read tire mm from the spring.

Everything is good here, I stripped out all the extra weight I could from the car, however trying to decide if I should remove the 2nd battery or leave it in. I am thinking I might want to overfill the oil by an extra litre just to be on the safe side in case I do any extended high rpm stretches through the corners.

See ya all in little over an hour. I'll be at the McDonalds around 9:15-9:30 ish.

Dave, I know you're a little excited, but you might want to post in the http://www.westcoastfieros.com/forum/forum_posts.asp?TID=2022&PN=1&TPN=1 - correct thread .

Oops, I was reading this thread but thinking about the other one.

Ok I run 16x7 with a 30 or 35mm offset and frankly love it. My 245s on the back have no issue with being too close to the strut tower, and the wheels sit out of the fenders just a tiny bit. Gives it an aggressive stance.

See, I personally like my tires to be within the bodywork.
