I'm currently doing the spring relocation and mini tub. The reason being is it opens up more options. If you look at standard cast and 2 piece 18x12 and 19x12 rims, most are offered with offsets in the +5 to +30 range. I can also go with a wider slick in the back if I ever want to go to the strip. Yes, I am also narrowing a 8 3/4 rear which costs money too. I see rear end narrowing getting thrown around as being cheap. I can't see that coming under $1000 with new axles for the average Joe.
72bluNblu, you should write a book for all these guys. Thanks for all of your info. You're an asset on here.
