Best option for rotors

[DatsunZman04]

I have recently purchased the toyota brake calipers for a little upgrade on my 240z. I noticed my rotors look terrible and wanted to know if what is the best rotors to buy without changing the hubs? Could I use a 81 maxima rotor? or is it the same size? Or should I just buy a pair of standard sized slotted and cross drilled rotors. I was just wanting some insight, I know theres probalably thousands of combinations and these questions being asked all the time. I just need a decentcheap fix so I can get my car back on the road. Any help would be appreciated thanks, DatsunZman04

 

P.S I will be switching my brake booster, master cylander, and a proportioning valve so the calipers will be working properly.

I presume you are doing the non-vented Toyota caliper swap which utilizes the stock solid rotors. Save some money and just go to Autozone etc. and buy new stock rotors. While you are at it you might as well replace the wheel bearings.

 

If you are going to replace your master cylinder (MC) go ahead and install a 1979-1981 280ZX unit. That way should you decide to replace your drum brakes with disc brakes you will be all set. The Toyota swap with solid rotors and 79 280ZX MC was the first brake swap I did. It was only slightly better than stock, but eventually I replaced the solid rotor setup with the vented Toyota kit from Modern Motor (MM) Sports. There was a obvious improvement over the stock brakes. Later I added the MM 240SX rear disc set up and proportioning valve. Lots of pros and cons and differing opinions on these swaps so do a lot of research in the brake and FAQ sections.

 

BTW if you use the 280ZX MC you will have to adjust the length of the booster push rod that pushes the MC piston. There are several good write ups on this in the brake section.

 

You might want to look at the Brake section under Frequently Asked Questions as many of the brake swap technical issues and pros and cons are answered there.
