I agree This idea and 23yrRebuilds "cross over" idea make the conversion very simple.Gregs672000 wrote: WOW, if you don't have to do much to mount the caliper you have solved a lot of the problems upgrading to a vented disc! The machine work is minimal to say the least.
I think the Maxima you used was 275 mmGregs672000 wrote: As I recall, all I did on my maxima rotors (which may very well be the same)
Gregs672000 wrote: was to reduce the outside diameter a bit, cut the rotor thickness down to match the spec for the 4Runner caliper, and hone out the center of the rotor so the Roadster hub would fit over it (instead of modifying the hub)... as I recall there was a clear "lip" of material on the rotor where the hub would fit through that was easy to remove with a grinding stone and a drill without having to worry about it being centered (because the lip edge was clear if that makes sense... it guided your work on how much to remove).
The first time I fit the rotor I bolted the roadster to the Altima rotor (flang to flang) using a 1/4" piece of 1/2 x .028 tubing to shim the larger hole in the Altima rotor to the 7/16 bolt and cut it with my die grinder and a straight cutter. I use the shank to ride on the roadster rotor as a guide. It worked great.
Just need to make a spacer (I am going to use the ones I made for the Volvo Solid rotor calipers that are coming off. I am test fitting on my Yellow car, than I will exchange them over to the teal blue car.Gregs672000 wrote:
The hard part of the 4Runner conversion has been the need to modify the caliper mount... it was really a custom job. If the Volvo vented caliper bolts up to a Roadster mount that would be awesome and a VERY easy modification to our brakes. Great work!!! Really excited to see how this comes out.
