So these are what I want to put on my 85 Z28 with stock style brakes. Does anyone see any fitment issues?

 

None of the links are working.

 

That's because he pasted the URLs as text, didn't insert them as links. Copy-and-paste into your browser works too.

What BeyondZ28_85 meant to say...My answer:
1) 4.3" backspace is too little. You need more like 4.75"-5.0"... IIRC.
2) 295/55/15 is 11.6" wide x27.7" tall. That's awfully tall and wide for the front for a drag style setup. Besides I am guessing these are intended to be a rear tire. These would fit the rear easier than the 30"...
3) 30" tall in the back?! Others have run a tire that big, but I bet it took some clearancing. With the extra 1/2" the wheels move the tire outboard, you are probably hitting the body.

 

Sorry about the link issues. I have to choose between 4.5" backspace or 5.25" on the rear with the 15x10" rims unless I find a different style.

Here is a link to the 5.25" bs rims with 0 mm offset:

Would those be my best option? I've been reconsidering the tire I put on the front as well. I actually want the car to handle which is why I want a 15x8" in front instead of a skinny. I might buy a matching set of skinnies for strip use later. I'm building the car to perform ok at everything instead of excelling in any one area. So the plan is big sticky meats outback that can corner, but with a limited slip locking differential will cut decent 60' times at the strip. Later, I'll prolly get a dedicated set of strictly track slicks and skinnies for drag. For now though, I want something that will really handle on the street and put the power down. If anyone knows a better set of tires to put on 15x8" up front and 15x10" in the rear I'm all ears. I had a drink or few when I was thinking about putting those tires up front. Sorry guys.

 

So I rethought it, and I'm going to put the tires I listed as being for the front on the back, and go with a 235/60-15 up front still with the 15x8/15x10 rim size.
