I already ordered the studs, so I hope there isnt a problem. I plan on putting 96 1.25" studs with plastic backers down the middle on my 04 600 sdi. While doing a search, some have talked of clearance problems with a 1.25" stud. I plan on using the 1" tunnel protectors. According to all of the charts I have found, you want between 1/4 to 3/8 " of stud above the lugs. Isnt this what 1.25 is on a 1" track? Also so many have talked about only studding a rev down the middle, why is this?? I have always studded the whole track on my other sleds, with no trouble. Any info you could pass on would be appreciated. Thanks.
