944-RX7 arms are only 7.7 lbs each.....
Was able to get another set of these built....All 944 dims were CMM verified and transfered to the adapter dimensions. All new graphite impregnated 60a polyurethane isolators pre-installed. Also has a brand new set of replaceable 17mm ball joints and the adapter brackets are made out of 4140 steel that is 4x stronger than the Rx7 joint that was removed from the factory. T6061-T6 billet rear control mount adapters with new rear mount bolts. I will ship with new threadlocker nuts so you can select for either late or early offset position of the balljoint. You can also mount the bracket either on top (V8 swap/1" x-member drop) or below the arm for normal 944 geometry.....
I gave these a brushed alum look, but they are ready to paint if you choose. I shot mine with Red VHT caliper paint and it's still shiney after 4000 miles on my iron-block V8 swap....
EDIT: Someone asked... they weigh only 7.7 lbs each fully assembled.....
$625 shipped in the U.S...... Just PM for details
