Guldstrand mod ??

...If these arms are that much better, where is the data? Where is the test mule with numbers to back it up? I’m not saying that there isn’t one; I just have yet to see it.

I am doing exactly that as we speak. I am about done. I am just redoing some of the measurements to varify the data. Some of it is interesting indeed.



One thing to keep in mind with the QA1 conversion is that you should beef up the LCA. By using that conversion you put all of the weight and stresses of the front end on the two bolts holding shock to the LCA.

Thanks guys. One more thing: by swapping upper and lower arms to tubular arms, I’m thinking the weight savings would be around 50 lbs overall off the front. The stock arms are pretty heavy and if I’m right, that would be worth the extra cash (I’m taklin’ Howe arms ~ $50 each not GW and the like for $600). Looks don’t do it for me as my car is so low that you couldn’t see the damn things anyway.

"I’m thinking the weight savings would be around 50 lbs overall off the front."

A quality set of aftermarket arms i.e GW, Hotckhis, DSE are marginally lighter than stock first gen parts if at all. There are much better places to put your dollars if you are looking to remove weight.

I didn't see it mentioned in this discussion, but I'm sure I read in the past on this site:

Keep in mind that most seek higher spring rates for handling. Coilovers or not, stock lower arms have been known to break around the ball joint area. So, even though the aftermarket lower A arms may not change geometry or handling characteristics in themselves you've got to consider the strength compared to a stock 35 year old A arm.
