thats normal run out for thickness in the industry it will vary about 6-8 thousandths tops thats why when they call for .118 tube you use .135 tube so that way it will make it past tech (a big mistake alot of beginners make assuming that the tollerances can be held to a tight standard) , I can find other places to loose the weight in the car gained by the extra thickness .

Yeah.......we're pretty lucky that the place we get it from now is pretty top notch. They are just up the road and they supply a lot of tubing and materials to the racing industry......we check it right there and if it's not what it's suposed to be (which is rare now) we don't get it. With this round track stuff you have to build it as light as humanly possible......in fact for a lot of the dirt stuff I do the main part of the cage is 1 1/2 .095 and all the front and rear kickers and down bars are 1 1/2 .083......which is ok by the rules........every bracket has holes in it....we use tubular bolts a lot.....grind unused thread bosses and "lumps" off the engine-trans-and about everything else.......it's pretty crazy but thats what it takes.........
