15" SE 7 spoke clearance
 

I know this has probably been answered,

will 26mm non turbo 300zx brakes clear with these wheels i will space them if necessary but i dont really want different wheels

also when installing these brakes can i use 300zx stock lines thanks

only if the spokes are flat on the inside, if they are raised they will not fit.
