I would go with a proven set up. The VWR's work well so far, I was looking at AP 332 with 4 pot or 6 pots, the 4 pot is a similar price the the VWR, the 6 pot more. All offer a good weight saving. As the VWR's and AP's are well used on track both options are good.
I originally went VWR as they are 352 by 32mm and have 6-pot calipers and cheaper than AP. The quality is not quite as good in finish as AP (paint, casting etc) they are Caparo not AP.
I would choose who to use for fitment and buy through them. Long delays on the AP kits (6-8 weeks), I waited for VWR to stock again, so they should have kits on the shelf (I suspect).
Worth noting fitment challenges with TT bottom arms.
DT are usually expensive, Balance would I suspsct fit as well ?
