Re: Tubular A Arms for A1 chassis (ABA Scirocco)
Nice link!
What is the stress ratio for those?
strain on the unibody too much or???

Last thing I would want to do is add too much rigidity to my coupe.

I'm pretty sure they were around 300 a pair, maybe more..

Just got this email from the vendorquote:[HR][/HR]Fully rose jointed control arms built to any geometry in Mild Steel are $1000.00. TiG welded 4130 Cro-mo are $1250.00[HR][/HR]

my friens and i started a thread on this in our local group. If you are worried about saving weight you are looking at the wrong piece, these things don't weigh crap anyways. We thought that we could use a piece or round steel thick walled pipe to weld to the front and back of the stock a-arm- f course making sure it clears everything....

Does the cost to make them justify their cost? That seems like alot of money for those.

I can't think of any big advantages and one major disadvantage, with the stock A-arms if you slide off and hit a curb the damage is likely to be confined to the A-arm, a cheap and easy to replace whereas with these ones the A-arm will probably survive but instead damage the A-arm attachment points and maybe the frame, a much more expensive repair.

I was about to post the same thing the same goes for seem welding the control arms it strengthens them but in an accident the car will bend no the control arm. The stock control arm is made to bend.

Hey Matt, just curious, I discovered the benefits of a "weak" lower control arm the hard way, how about you?

My Caddy will be made to stay on the road. With a subrame the atachment points wil not bend. I want them for less weight and adjustablity. On some of the arms you can install the larger ball joint also.
Any ideas on other sources?

We always PLAN on staying on the road but sh!t happens and when it does, something's got to give, it may as well be the cheapest and easiest part to fix.

The only advantage of tubular lower control arms (LCA) is possibly less unsprung weight. However I recently weighed an A1 series LCA and it weighed 5 to 6 pounds. When calculating unsprung weight of suspension components, you take 50% of the LCA into the unsprung corner weight.....so you are only looking at 2.5 to 3 pounds of LCA weight contributing to the corner weight.
Don't know what the tubular LCA's weigh but at a $1000 per pair, I think I will keep my stock factory VW LCA's since they don't add that much weight to the overall unsprung weight.
I seam welded my LCA's for about one inch in various places along the "joint" line of the LCA. Even with Hoosier racing slicks, I have not noticed any deflection of the LCA's after a season of hard racing. I truly believe that tubular arms are probably "overkill" unless you are running F1 or some other pro series with titanium arms. Cheers, WWR. http://****************.com/smile/emthup.gif
