NCP90 Rear Drum to Disc swap

Ok so after hitting some bumps a little to hard and hearing the clank and then reading more on threads here I found someone saying they thought it was the brake hose bracket that hit and not the fuel tank, I have had a look and they are right. Not sure how I did not notice this before.


Yes those are contact marks above the brake hose on the chassis rail.

I will be going back to the normal lower suspension mount holes. This is not a safe mod at all. a larger than normal bump in the road will crush the brake hose or severe it.

This is 100% a MOTORSPORT ONLY modification that requires relocation of your brake lines.

Just thinking about this the upper hole is not on there for motorsport, toyota would never do that this is for the 1.3 litre 4wd vitz, it has a rear diff and drive shaft that needs to clear the rear subframe and has a different rear subframe again to the RS/base along with a different fuel tank. The 4wd are always automatic 1.3 litre 4 speed auto and kinda rare.

No more recommending this to people everyone.

Edit: the 4wd vitz are 2nz-fe not the 1sz-fe.
