NEW WHEELS MB OLDSCHOOL - HELP WITH SIZE

[streetworkxs]

I want to put the widest wheel I can fit on the rears on my '86 regal without having problems. My car is lowered 2'' in the rear and 3.5'' in the front. Will these sizes/offsets work for me? Also I have beltech 2100 drop spindles and plan on adding ls1 discs, will that push my wheels out a little further in the front?

and for the front I want to do 17x8's but I don't know which offset I need that will work. I have a choice of 0 offset and 7. THANKS FOR THE HELP!

I have those same wheels (chrome though) on my Cutlass in 17x8 with 4" backspace and I am running 255/45/17 on all four corners. My only issue is that I would like the rears to stick out just a little more then they are, but I am very happy with the way they are.

I am not sure how they will fit lowered though.

it always confuses me when they list offset and not backspacing. On the site they only list the offset. Which offset did you use for the fronts? Is there anyway I can fit 17x9.5's? 17x9.5 w. 6'' offset?

Can you send me some pics of your car? [email protected]. Thanks~

Back space vs off set explanation

Since I was confused on Backspacing of a rim I thought I would post this for all the other rookies on the forum.

Thanks to jdpolzin for setting me straight on it.


How to Measure Wheel BackSpace:

Items required to measure wheel backspace:
Tape measure
Straight edge
Wheel w/o tire (preferred)

The easiest way to measure backspace is to lay the wheel face down onto the ground so the backside of the wheel is facing up. Take a straight edge and lay it diagonally across the inboard flange of the wheel. Take a tape measure and measure the distance from where the straight edge contacts the inboard flange to the hub mounting pad of the wheel. This measurement is backspace. The above photo shows three wheels with 2",3", & 4" backspace.




Off Set: Measuring Wheel Offset
To calculate offset you'll need the following measurements:

Wheel backspace
Wheel Width
Wheel Center line (outboard flange to inboard flange measurement / 2)

Subtract:

Wheel center line from Wheel backspace to get offset. If backspace is less than the wheel centerline the offset is negative
If backspace is greater than the wheel centerline the offset is positive

Tip:

To convert from inches to mm multiply by 25.4
To convert from mm to inches divide by 25.4
Backspace to Offset Conversion Chart
The table on the below is a quick reference for finding offset, pick the rim width and follow the row over to the backspace of your wheel.
