Default Backspacing, what is too much/little?

Is there such a thing as too much/not enough backspacing?

I'm looking at getting some soft 8's with 2.5" BS and was wondering if there is anything I need to take into consideration before doing this?

Nothing really. I know the stocks are 5.25" and rub on LCAs at full lock, so i'd say that's too much backspacing. 2.5" will give you a nice stance, but i've never heard of any downsides to having BS that low

Too little backspacing puts extra stress on front end parts, especially with big heavy tires. Hubs and ball joints will wear faster

I've never heard of a soft 8 with that little of bs. How wide are they? You sure that's on offset?

Depending on what you like...less back spacing means your wheels will stick out further...I prefer a 4 inch back spacing...looks good with 31s

I'm Gunna get 15x8's with 4.75" since I don't want new flares so it'll have to be inside 99 stock flares.

They're ProComp Series 98 RC Monster Mod Wheel, 15x10 with 2.5" BS.

Right now I'm running some (unknown brand) soft 8's with I think (not sure, PO told me and I haven't measured) 4.5" BS but then I put 2" spacers on as well. This would eliminate my spacers and give me the same stance, but I think I want to keep the spacers and get the 2.5" BS soft 8's.

^x2 on the wheel bearings.

Wheels size and width along with back spacing all have to do with what size tire you are going to run. More information about what you intend on doing as far as lift and tire size will help get a more informed answer.

I'm running a 3.5" lift on 33x10.5 right now on 17" soft 8's with 4.5" BS.

I'm planning to keep the lift at 3.5 and run 33x12.5, and then eventually bring it up to a 4.5-5.5" LA lift in about a year to a year and a half.
