Wheel and tire sizes and offsets
I know this will ruffle a few feathers as much as has been written on here about this but i'm not looking for opinion as has been ask in the past. I have 84 sport coupe rear drum brakes and stock suspension. I am trying to achieve stance and wheel and tire size and look of Nufnuffz28's july car of the month winner. Has anyone seen a third gen with this setup as he doesn't mention what offset/backspacing he uses, and what wheel offset they were using. Not interested in suspension mods or body mods to make this work. He uses 18x10 wheels on back with 295-35zr19 tires and 18x8 wheels on front with 275-35zr19 tires on front. Would consider 18 in. wheels.
Thanks
Thanks

Re: Wheel and tire sizes and offsets
Oh, that is just a measurement of the outside lip on the wheel. People sometimes like to see how wide they are.
Fenderwells(besides the fender lips being rolled and some hammering on the inside) are factory and untouched.

Re: Wheel and tire sizes and offsets
18 or 19x8 would usually have 4.5" of backspacing. 4 will work, but it too far out for some people.
18 or 19x10, again 5.5 works, but is too far out for most, its a more common offset for smaller 15 and 16" wheels. You can tuck a 18 or 19" wheels further in since they clear the bumpstop area better. If you can find 6" of BS, that's a good fit.

Re: Wheel and tire sizes and offsets
Is this based on a car with rear drum brakes, which is what i have, or are those figures based on a car with rear disc brakes because i think rear disc put the wheels outward about an inch more than drum brakes i think. Thanks for the info and any suggestions are helpful as i'd really hate to go out and spend $1500.00 to $1800.00 just to find out i'm having a scrub and rub problem.
