I am installing 1989 Toyota 4runner calipers on my 240z with 1985 300zx rotors. The caliper is hitting the back of the rotor and needs about a 1/16" 1/8" to seat on the mounting bracket where it bolts to the strut. Has anyone else had this issue. I have the 240z to Toyota conversion hub ring from Techno Toy Tuning.  

Pretty sure I've seen people write about it.  I seem to recall spacers being discussed.

Are you really in India?

I did this same conversion on a 71 Z using the stock rotors. Straight bolt on. Is there some advantage to Using a ZX rotor?

I was told because it is a vented rotor 

 

I used thin shimming washers to center the wilwood calipers on the vented rotors.   

Thank you that's a good idea 

My 1972 240z  has the original stock disc brakes up front and drum in the rear. I went for a ride the other day and decided to brake and even though it did brake, the stop was not as firm as my Honda CRV 2012. Should i consider installing disc brakes at the rear also to get a precise and instant stop? If so which Brand and type?  or to achieve this i will need to replace the 2 stock original disc brakes and calipers with a new set of brake pads and calipers for the 4 wheels? Which Brand and type? I am not going for a race but safety is a great concern for me!

Check out this thread, there's a lot of good info in it and from what I quickly scanned I think you do need spacers. 

 

Two options on the Toyota swap. One is vented and requires a spacer, other is non vented and no spacer required. As to the other person asking about braking, do the Toyota front swap before switching the rear. Way more bang for the buck and a huge difference in braking.

Here is what I used for rear disks.  You have to cut the dust shield off, or like me just unbolted it.  

Brackets- https://zcardepot.com/all-products/brakes/rear-brakes/rear-disc-brake-caliper-conversion-bracket-set-disk

1986 maxima calipers- Ebay then rebuilt and powdercoated

1985 300zx rotors- Cross drilled and zinc- http://www.silverminemotors.com/datsun/datsun-240z/brake-kit-individual-parts/rear-disk-conversion-rotors

Stainless lines – Stop tech 800-1099- I think i got these from zcardepot.  

I only use this car on weekends to cruise but would like to have a better response during braking. Would you still recommend doing the brake drum conversion at the rear or would it be greatly improved by just having better brake pads?
