Like a lot of guys on here,I have a small budget for toys...$1,500 for control arms is completely out of the question.I simply look at performance gain for the $$.I would like to see a blind test of these vs. ones 5x the price,and see the results on the Auto-X.
I was skeptical about the build quality of the arms until I held them in my hands.Welds were nice,powder-coat nice,H/D hardware,etc.The frame will fail long before these give up.Fine for my street car that might run a local Auto-X a couple times,if at all.
If you are a Pro-Autocrosser,where sponsors pay winners for product use,it may be worth using the expensive ones.Most guys are not in that category.
Just like a house addition,I look at what the part will do to the resale price.Will $1,500 arms that no one sees add $1,500 to the value of the car?If they do,you are luckier than most sellers...I know...you are gonna keep the car forever...I thought so til Life happened.
