Default 4 piston calipers with sport rotors

I have been thinking of doing miata sport rotors with the 86-92 rx7 Turbo 4 piston calipers seeing as each caliper is 40 bucks each. So I wanted to know what you guys think about doing this on the front and rear.

These calipers? It's been found to be not very possible on our cars. At least not worth any savings below $600, the price of a real BBK.

Do any of you know the measurements of the mounting holes on the spindle for the caliper. Track speed sells a dynalite caliper kit that works with the corrado rotors. I want to know this because wilwood has a bunch of different lug mount distance for mounting. So if i could find one thats close or would work i would just have mounts made and run the 01-05 sport rotors.

There was some guy from Japan that had his car build up on cardomain a while ago that used the 4 piston rx7 calipers. He had custom mounts made and said that they worked really well. He ground off the mounting points on the rx7 calipers and welded new mounts up. I don't know how many people here are familiar with welding cast metals but if you are this is an option! His car was blue with greddy turbo and used to have a super awesome aluminum wing. He also had a pimped out toyota van on the same page...

Yeah, because getting Wilwood Dynalite calipers is soooo expensive...and getting the mounting brackets is next to impossible!

Or you could just buy the brackets from chikara...

I did this conversion with my own custom brackets, and some machining to the out side of the calipers, I used 290mm rotors.They work very well, but you are very limited with 15'' wheels that will fit, It's not so much the inside diameter of the rim but the clearance to the wheel center ( eg, 949 wheels need 20 mm of spacing to clear the bulky caliper) I have found the same issue with 16s and 17 rims. Next time I would just buy a complete kit, the time spent on machining , and parts to make them like new was very close to buying the kit , and there even cheaper now. they do have excellent feel and stopping power, I have not driven on willwoods to compare.

I'm glad you figure it out, and I'm glad we now have anecdotal evidence that it's not worth it in the end.

Now pics or ban.
