anyone here know where i can info on mini tubbing my 87 iroc.

 

Not sure on the minitub, but S&W sells a complete rear sub frame kit to mount big ole tires under a 3rd gen.

No such thing as a minitub on a third gen. The frame rails, if you can call them that on a third gen, are already at the inner fenders. The best thing you can do is to cut off the bump stops, cut out the section over the spring and replate with a thinner piece of sheet metal and cut out the front inside corner if your wheels are too tall to fit.

 

Or get some fender flares.

 

what size tire are you planning on running?

 

i want to run a at least a 295 but the wider the better(315,335)
i am doing this for cornering not for drag racing

 

you can fit 315's without any tubbing, just requires the correct offset wheel, massaging the inner fender well, and rolling the fender lip

 

yep, i run a 295 with airride.....no minitub. slight massage but no big deal. the offset is the key.

 

i want to run a 17 inch wheel
what kind of offset are we talking here

 

6.75 backspacing range.

 

kandied91z what brand are your rims

 

This is a perfect question.. I want to know as well.. I know I will probably have to roll the fender lip, bang in the inner fender alittle.. but what rim dimensions should use... I have a 4th gen rear so that throws things off too???? I want a 17 inch rear rim. like a 315/17/35.. But what should I get the backspacing like?
