Welcome to another Wisconsiner! I'm definitely planning on going to the Midwest 7s Gathering this year. Here is the LINK. Hope to see you there. Also, you can see what they did last year at the Midwest 7s Gathering.

Looks like you are making great progress. :cheers:


Keith, Very nice I was wondering if their were any other wisconsonites on here. I am going to try to make it to the 7 rally. I need to ride in one of these things!!

Don't give them too much to look at in one day, these guys wont leave you alone.



Hey Shawn, Nice to meet you. Thanks for the advise. Things will slow down for me too here in a couple months. You know how winters are. You'll do anything to fill the time.

Another great build :cheers:

Beautiful welds? Specs? AWS? I will need to see your WPS.

I worked in the field once and met a welder who said he didn't know what a WPS was. I told him it meant Whoops and every time he finished a weld and wanted the inspector to approve it, the welder had to yell out "WHOOPS!" as loud as he could and the inspector would come a-running to sign off on the weld. I quickly left the jobsite after that.

Hi, Its 2x1/4"

Consider your engine making 115 ft-lb of torque at the crank, with a 3.136 first gear, and a 3.27 rear end. That's ~1180 ft-lb of torque at the rear axle. Since our at least lightly modified installations usually net a little power over factory, let's call it an even 1200 ft-lb. That means each of those straps is reacting against up to 600 ft-lb of torque. It may be fine, but considering the section properties of flat stock, it doesn't exactly inspire me personally with a lot of confidence either...Just some food for thought.

Just another thing to consider, it may be fine as is, but I'd also want the connection on the axle in double shear. Would be really easy to do with just another braccket similar to the ones youve already built.

Single shear of a 5/8" bolt isn't enough? Plus a total of 2.5" of 1/4" fillet on both sides of that 3/8"bracket. I think it's got some beef.

I wouldn't be concerned about it physically shearing off, more the possible bending and movement associated with repeated "launches" which would lead to failure. Others would be able to offer better advice than I, just my $0.02.

Its killing me to not work on the car this weekend. I have front rotors on order and i have to pick up square tube for bracketry, .095DOM for bushing sleeves. next week is spring break in Florida where winter dosen't exist thank God, I am so sick of it. It will be a couple weeks before the wishbones get laid out.
