Just to show,
These 2 pieces are made for the rear suspension to serve as a proper spring cup, and height spacing for the spring to sit on. This is needed when switching from Stock steel Rear lower control arms, to Aluminum rear lower control arms (AKA Mark VIII H - Arms) which normally use AIR BAGS.
Because the bottom of the spring will be in a lower position on the Aluminum unit, this spacer corrects the height, and also angles the spring base to sit nice and flat. Results show the height is restored back to match the front suspension height, and evening the car out. (instead of having the rear squatting down)
This has already been done buy an owner who was kind enough to share his plans (pictures below) for having the part CNC machined (this is discussed in more detail on TCCOA), the plans are being duplicated, If I understand correctly the first set will be tested and measured before the full run just to be extra sure. Sam already has 11 sets spoken for, we need about 17-19 more to get the ball rolling. Although I suspect their maybe be interest for even more than 9 sets, unless a similar solution has already been developed.
50 perches - $130 a set
40 perches - $140 a set
30 perches - $150 a set.
The price was quoted from another shop at about 3 times the cost to machine these out of 6061, so this pricing seems reasonable if there is enough interest it will happen.
Thanks to Sam!
