Okay i was messing with my turbo car but im back to my 3rd gen i missed it to much but anyways i found Drag Stars,For sale and they measure 15 x 10" with 4.5 " backspacing and wondering what will i have to do to get them to fit i already rolled the fender lip.im prolly gonna run a 275 tire or a 305 or something in the small 3range at most a 315.

thanks for any help i missed the torque on demand got sick of the spool then go lol anyways yeah and if yah got pics that will help also.

 

Normally 10" rims have a 5.5" backspace to tuck everything under the fenders. The 4.5" backspace will push the tire outward more.

I originally had some 26" tall ET streets on some 3.5" backspace rims. They weren't tall enough to worry about hitting the fender lip but stuck out way too much for my liking.

 

so will my back spacing make the rims stick out less or more and how much would they stick out past the fender?

thanks for your help/

 

Compared to a factory rim? They're probably going to be close to the same. What's the backspace on a factory 7" rim?

This is the only picture I have when I had my 3.5" backspace rims on the car

 

so what size would it be to get it to fit in there or just barley stick out cuz i wanan run a 305 tire with my 496 motor thats going in im mostly useing it for street use/if you catch that the read end i have has 4.56 gears its a 12-bolt same width as stock rear.just i wanna run 305 but not have it stick out like a sore thumb i dont care if it sticks out a inch or 2 but not like a foot.
