Trouble is 9 times out of 10 the starter isn’t the issue, the wiring is. And the best starter in the world won’t fix that. Some of the grounding I see out there is pathetic. And small azz power leads too.
i have to agree with the wiring issue. from the key or button to the starter, don't skimp ! just going up one wire gauge size can sometimes make a HUGE difference. also, have as few connections as possible, and make sure those connections are clean and tight.
