I like your thinking!!!!!
I have a set Cupra arms....... with TT ball joints waiting to go on the car when I get time to get it in to a
Garage. They are not a direct fit by the way and anyone else trying this will be doing it at their own risk.
2 of the bolt holes lign up perfectly. The other is out by just over 3mm and I have carefuly elongated the hole with a round file so a 10mm bolt drops in neatly. They are also non-adjustable as you will see when i finally work out
how to post pictures on here. A tiny amount of material had to be removed from the lower arm also. I am happy with the fit and finnish and am confident that the strength of the components has not been compromised.
Cupra arms are aluminium so no weight saving there. I picked mine up off ebay for £20.
The ball joints are £73inc vat from audi with no discount.
Can anyone tell me
how to post pics? or I can email the pics to ya if thats easier!!!
