I've had the original Capps Automotive pieces on a few B-Bodies,
I didn't care about weight really, I knew it was lighter & more room,
less weight with tubular stuff alum. stuff everywhere & the battery in the right rear trunk,
it'll have much better front end travel & much lighter on the nose to change weight bias,
toward the rear...
I now have a QA1 K-Member now, $585 IIRC {I still need to install, some day when I feel like it}
shipped directly from QA1, I purchased thru Summit Racing {no shipping costs/best price}
I now have a QA1 K-member,
SPC Upper Control Arms {adjustable on the car}
& the original Capps Automotive {still new in the box} Lower Control arms
QA1 makes them too, even with the sway bar tabs on them
also a Uni-Steer rear steer rack-in-pinion, I bought years ago from Year One,
that is already on my 68 RR
{I would not recommend it thou severely limits your oil pan & header choices}
I'm making custom step, rear exit, with Flowmaster Scavenger 4-2-1 collectors headers anyway...
I like the tubular design more for,
the room for headers,
more room for oil pans,
more front suspension freedom of movement
much cleaner appearance/style than stamped OEM stuff etc.
than the any actual weight savings,
IIRC it was like 70#'s to go to all tubular front pieces, K-member & both upper & Lower control arms
& Drag style lightweight Wilwood disc's & a rack-in-pinion box
more if you ditch the heavy torsion bars & go to coil-overs, it's like 100#'s off the nose
you have to modify the lower control arm mounts,
because the torsion bar will no longer be in & hold the LCA's forward...
