[QUOTE="SpectorV, post: 9320200, member: 27907"] offset is how far the center line is off of the mounting surface. If the rim is 10 inches wide the center line is 5 inches. The offset (can be positive or negative (inward or outward of the centerline) is how far off it is from the center. Every 1 inch = 25.4mm So 43mm offset is 1.2 inches. That means if you bolt the rim up on the car that is a 10 inch rim with a 43mm offset (1.2 inches) that it will be offset 1.2 inches from center outwards. Basically more of the rim is inside the mounting surface than outside. [img]http://www.discounttiredirect.com/images/wheel.offset.gif[/img] Take the offset + center line and thats the rims back spacing so 6.2 back spacing on a 10 wide rim. So 10 - 6.2 = 3.8 frontspacing or how much of the rim stick out in front of the mounting surface. For the rear 3.5 is about the normal limit, some rims go to 3.75 (or 3.8 in your case) and are ok, 4.0 inches is as far as you want to go for the rear. Thats fender flush (with tire) and you will need to roll your fenders probably. Yon may can get away without rolling at 3.75~ just have to try and see. For the front you want the front spacing around 3 inches (not muchless) on a lowered car the rim is tucked inward due to the A Arm design so consider that. My rims are 18x10 back wtih 6.00 back spacing 4.00 front spacing in the rear 18x9 front 5.94 back spacing 3.06 front spacing [/QUOTE]
