If you got the longer bolts you should be alright. Most people that have trouble with spacers don't realize how many threads you give up for the extra space. I was at Hallett Raceway in Tulsa when a 911 with spacers on it lost it. High stress corner, the outer rear wheel just folded under the car and they did a barrel roll. Thankfully no injuries, but car was totalled. They had used spacers with stock bolts. They were too short, so they only had about 1.5 turns taking all the stress of the wheel. Ooops...
