FD Weld fitment offsets and bolt Patterns:
Hey guys, I know this has been an on going question so here goes. Hope this helps.
Bolt pattern: 5 x 4.5
Front backspacing with a 15x3.5" wheel: 2.5 backspacing
Rear 15x8" wheel will need a 7 1/4" backspacing.
NOTE:
In order for the Welds to fit in the rear the brake caliper and toe link nut will need to be grind down.

I saw someone post 1.75" backspacing for the fronts so thats what I bought. What issues am I going to have?
Does anyone know what backspacing would I need for a 15 x 10 rear rim?

Pro Star 96 series:
15x8 rear with 5.5bs and 4.5bc Part # 927-96-58210 from Jegs
15x4.5 front with 2.25bs and 4.5bc Part # 927-96-54202 from Jegs
You have to do the grinding like ErnieT said, and 1/4" spacers in front, 1/2" spacer in rear to clear drag link (Mr Gasket spacers don't work well because the slotted universal bolt pattern design causes them to shift on launch). Pro stars are a pain in the *** because of the lug-centric design with floating spacer. Also you need 3" extended lugs.
Major problem with 96 series XP is you can't get them in 15x8.
Jegs is actually cheaper than Weld's website.

Here is my combo:
Front
Magnum Drag 2.0 - 786 Series Wheel
15'' x 3-1/2''
5'' x 4-3/4'' Bolt Circle
1-3/4'' Rear Spacing
Rear
Magnum Drag 2.0 - 786 Series Wheel
15'' x 10''
5 x 4-3/4''
6'' Rear Spacing
26/11.5/15 ET Street
I also run Wilwood brakes and Feec wider fenders/Feed quarter panels so this doesn't really apply to everyone

I made a mistake guys. I have 15x4.5 not 3.5" wheels, but if you get the allumastars they make them with the correct backspacing (2.5) that no spacer is needed. They are pricy though.

Stock lugs are 12 x 1.5 and the extended studs are available thru ARP but hard to get. Ari is the best i found to get them. I actually drilled all mine out to slightly larger studs.
