[QUOTE="FullMetalFabworks, post: 450718, member: 5910"] Good looking build and nice fabwork. I can tell you about a few weak links on it before you get started and hopefully save you some time testing and fixing broken stuff on an assembled car where things are in your way; the factory sway bar mounts, the factory front A-arm mounts, and the chassis side pivot area for the radius rods. The factory sway bar mounts are junk and WILL break before you can finish a 1000 mile race, so unless you want to be welding those in the pits I would cut them off and re-do them with 1/8" 4130 ( I think they are like 12ga MS stock). The A-arm mounts up front would probably last a race but they will be totally trashed after it, this is an area I would sacrifice a pound or so and remake them out of chromo with some gusseting, again it will be a lot easier to do it now rather than after they junk (ask me how I know). On the radius rod mounts on the rear, I have seen the bolts loosen up, when hammered hard enough, and then the misalignment spacers start to egg out the bulkhead they are mounted to , so definitely red loctite the **** out of those and if it were mine I would add weld washers on the chassis side and I assume whatever kit you are going with for the aftermarket arms will come with a new plate for that area. Will you be using the factory motor mounts? If so the top bolt on the rear most mount likes to back out so race prep that for sure, If not, did you lower the mounting location of the motor? Im not sure how it is on the 4-seaters but on the 2-seaters the mounting puts the trans output substantially higher than the center carrier bearing support (non cancelling angles) and is where I think the driveshaft vibes everyone complains about on these comes from ( and not so much the out of phase yokes).
