Ask Mr. Mike: GM Engineer

You may already know Mike. He built the baddest ZR2 that has ever roamed this earth. He drove his ZR2 in Petersen's 4-wheel/Off-Road "Ultimate Adventure" in 2003 and impressed a lot of people with an IFS S10. A "wealth of knowledge", but also an extremely busy man these days. Ask him any specific ZR2 question you may have that you don't feel could be answered elsewhere in the forum. Please be precise. Please be patient. His professional and experienced answers are well worth it. Be sure to visit his website before you leave!
