I have a set of MSR Wheels 20X8.5 front, 20X10 rear both have 40 mm offset. I was wondering if these would sit flush with the fenders or will they sit in a little bit. Should I buy spacers since it is a high offset, because I want the wheels to stick out a bit. Thanks for your help guys

 

They will sit in. I suggest spacers - at least 20mm f and r

 

Thanks

 

Use an offset calculator and compare the current wheels with the new wheels. With a tape, check if you clear the strut housing, brake caliper and fender.

I don't know what the current wheel dimensions are exactly. They are the 18 inch stock that came with 2007 Enthusiast. I was thinking 25 mm spacers in the rear and 20 mm up front

 

My TSW 20's are an offset of 20mm on the front and they set even with the fenders, the back ones are an offset of 40mm and they set way in, I am going to get spacers for the rear ones, but like you I dont know what size to get with a 20x10 and a 285/30.
