Picked these off of a local forum.

[quote=""SoSlowS13""]15 dollars in hardware, a welder and stock s13 ruca's

This one looks crooked, but its not.

XXXXXXXX there is a grade 8 nut welded into and boxed in the outer part of the A arm the nut you see is the locknut. I doubt any of the value type Rucas use as strong materials as I used. I also used a poly bushing in the end instead of a heim joint because welding destroys the stock rubber mount. Even if I did not use a lock nut i would be impossible for the bolt to come loose Its just for added strength. Both sides dont have to be exact thats why they are adjustable. and as log as everything is straight the only thing the a arm changes is rear camber there is a totally different adjustment for toe. As for the way it looks it dont have to look like everyone elses thats what is called thinking outside the BOX. I paid 15$ to make these not including the poly bushings took me 2hours to fabricate. The cheapest ones i could find were 65$ shipped and GOD know who made them or what materials they used. I can attest to the materials and workmanship that went into these so I think they are far and above a better value than anything around. Here is the finished product......

[/quote]Just wondering what you guys think of it.

I dont think i could trust them on my car.esp initiating at 50+mph on the track...

from a functionality standpoint. I think they will do the job.

I think if the whole thing was boxed and then gusseted I would trust it for track use but not like that.

agreed.

box the whole thing... or dont bother. hardware wise... looks beefy.

remember kids, you have toe and traction rods up top too... these are NOT gonna take that much stress.

id run this over godspeed/isis any day of the week tho.

Grade 8 nut? But Nissan uses grade 8.6 and 9 OE for all suspension items. Thats my issue.

Use a grade 10 then. Then it won't be much of a worry.

touchy issue here for me, i still don't think id run them, but like MGE said, they are prob better than Isis, Megan, Godspeed etc..
