Here is the plan. Will ordered 3/8" inch hub centric (for 2003 wheels) spacers from Ray who now does the "UNDY" spacers over in SVTPERFORMANCE.COM and if needed will grind the .50" IRS bolt head down to .25", after I see how the spacers fit. That is the plan will know later next week and post the solution. 7/32" spacers will not work for total clearance (on ground and if ever in the air). I was also told the GS-D3s are wider than most other street tire brands for 315s....I know these 315 GS-D3s make the NITTO DR 315s I am running right now look like thin "Ten Speed" bike tires.....John
