Im sorting out my parts list for my new build and have come accross these,

COSWORTH 909 GRP N REPLICA ROSE JOINTED TOP MOUNTS

http://www.ebay.co.uk/itm/2610627382...84.m1436.l2649

now i have seen these before but i am unaware of how much a camber and caster adjustment they have over the after market eccentric top mounts like these ones

http://cgi.ebay.co.uk/ws/eBayISAPI.d...vip=true&rt=nc

can anyone shed some light on these, has anyone used the Group N style before? id rather pay a little extra and get the group n ones to match my shell and there fore i wont have to cut the top mounts off..

but id rather have full adjustablity built into the car in case its needed

cheers matty
