Hi here we have a pair of ls400 adapters for the 4 pot calipers £90 a set posted uk. You will also need an roll cast adjuster of some sort also oh and calipers {}
A pal of mine also has some freshly refurbished set of ls400 calipers in primer finish ready to paint in a colour of choice for sale if anyone needs them to go with these
No he doesnt but i have a pair that were removed from an ls400 look ok but id maybe do the seals for pesce of mind
