Grounding points for s13 with RB25 front and back?

[exodus5547097]

Is there any grounding points for s13? Front and back? I've relocated my battery to the back already and have seen my ground wires cracked.

Sub frame bolt is a good one, also the trailing link works too. transmission bolt is the best for the front.

There is no substitute for running a decidated ground wire from the battery to the front to ground that along the frame rail and collect the block and chassis grounds. Without this, I was seeing a lot of noise on the sensors making it difficult to tune.
