The front brakes on my R100 are not too impressive. I have a set of brakes from my ’83 RX-7 scrap car. It look like I should be able to remove the whole strut and brake assembly from my ’83, swap the top mounting hard wear and then the two bolts at the bottom should bolt up. Now it looks like this should work from just eyeballing it but I want to know if this can be done before I tear everything apart.

Just to clarify, I want to remove the brake and strut assembly from my 83 RX-7 and use the three bolt top mount (the piece that sits above the spring and mounts to the body) from the r100 strut to mount the ‘83 strut and brake assembly in the car. This is assuming the two bots at the bottom of the ’83 assembly will bolt into the R100.

If this will not work does anyone have any low buck ideas as on how to beef up the brakes on the R100?

Thanks for all your help guys.

 

brake hose threads on the 83 are different from the 70-71. You'd have to swap out much more than just the calipers to get it all to hook up. Can't comment on the struts, just the brake parts.

 

Thanks thats really good to know. Otherwise I would have been putting it all together and have no clue why it wouldn't fit together of why it was leakcing all over the place.

That just means I would have to find some sort of adapter or re flair the brake lines with a new fitting right?

Thanks again.

 

Would '79 brakes work?

 

79 and 80 brakes should work, but nothing later than that. I don't think there is an adapter that would take you from metric fine to metric course . . .

 

the r-100 has the same struts and brakes as the rx-3, 808.... but if you upgrade to an rx-7 front suspension, you will notice it will be to low to the ground and might affect steering as the tire will come in contact with the fender. You might want to consider the front struts from a 77-81 glc, now bear in mind that the bolt pattern changes from 110 to 114.3 mm. But if you upgrade to a glc suspension, you can use the larger brakes and calipers from a gsl-se or a 1986 se model....
