Has anyone had any problems with the Arraut Motorsports front tubular control arms? I have their front coilover setup with 1" drop spindles on my 88 Mera, After seeing the broken spindles, mine have the extra lower brace like this one, I think I will put the OEM spindles back on the car. I would like to keep the coilover set up, I would appreciate others thoughts about keeping the control arms made by Arraut.

I've never heard of any failures with the front arms, just the spindles. However if you saw the other thread, the OP now had the REAR fail on his 88 which pretty much destroyed the car.


Personally, I would leave the coilover setup on the car, put the stock front spindles on and get Rodney's 1" lowering ball joints.

I have the same setup, but I haven't put a lot of miles on it. I worry about the crappy parts all the time. I plan to leave it as is for now, I spent too much money on it, so I guess I'll just watch it and get under the car from time to time to check on the welds.

Do you have Arraut spindles on your car? I have about 8,000 miles on the Arrarut setup on my car and check it very close before I start driving it in spring and at least one more time during driving season. My setup has about 8,000 miles on it, so far no issues. Most miles are around town, some smooth and some kinda rough surface streets and some freeway. On the way to the 35th show there was a bridge approach that was under construction and I may have got some air when I hit it. The alignment stayed spot on and when I got home everything looked OK with the A arms and spindles.

The front spindles that failed are much different than the pair on my car and just don't look like a very strong design. Maybe Arraut forgot to put the lower support pieces on when they built them.

Bloozberry has the braced spindles on one of his cars, when the spindle failure showed up last year I asked Dave for his opinion and he said the ones that have the lower bracing should be good. If Dave thinks they are OK they probably are. If you are familiar with his background he really knows what he is doing. His fabrication skills are very impressive, his F355 is amazing.

If you have the same style as Dave which was the Held design, you should be fine. It seems Arraut rushed the assembly of the spindles and used a few shortcuts.

I posted this in another thread but I believe this is the cause of the failures.

With Daves spindle from Held, the weld seam is on the outside where all of the structural welding and gussets are.

On the spindle that broke, there is no seam to the outside which leads us to believe that they welded the parts with the seam inside towards the car. That would mean that the seam had no support and could easily split open under stress especially since the seam would run right through the cutout for the nut. In this pic, here's where I THINK the seam is located under the powdercoating:

I personally wouldn't trust my life to any part with welds that looked that way. They may be good welds and maybe they aren't but they look awful.

The first pair of spindles I got from them had two issues. the first issue was that the extra bracing between the round "tube" and the part were the steering link attaches was missing. The second issue was that the taper for the steering end link was drilled upside down.

I sent them back and the second set did have the extra bracing and the taper was drilled correct, however, i don't know what "taper" they used to drill them out, but it did not fit the steering end link. I had to get a 1/2 drill bit and clearance the end a bit to get the end link to fit into the taper enough to get the nut on far enough to put the castle nut/cotter pin in.

I had other issues w/ this pair of spindles. You could tell they were made on two different days or by two different shops b/c when put side-by-side they had several differences. some day I may remove them and install the stock spindles and try to figure out some way of getting the Wilwood calipers to still fit.
