@KatoKid Thanks Dave, I will sort the struts out on Monday. My rear calipers are like Aaron's not sure what the front ones are on his. Will need to go through his build thread.
Thanks @ZED660. My front calipers are definitely different from your ones but rear are the same. Ill take a picture tomorrow of the fronts I have and post it up.
Thanks guys, this is why I love this fourm. Great help
My car was weighed as part of engineering approval and came out at 1080kg with ~ 20 litres of fuel:
M3 engine and gearbox were just a few kg heavier than L series/71b
Bigger R33 GTS-T and R31 rears.
R200 in place of R180
All factory sound deadening removed and replaced by Builders Choice sound deadening in the cabin but road car so no cage.
My set up uses GTS-T calipers but its different to SW so check my signature for the link.
Either way you will need to swap struts from side to side as the calipers have a leading and trailing design with different piston loaction: refer the link below:
