Hey all, my rear end is on its way out and I am preparing to have it rebuilt. I have been looking for suggestions on the best replacement and have seen mixed reviews. Car is currently 600whp with plans to increase in the future. Car does see some hard street driving, has not been to the track yet but would maybe 1-2x per year and I do enjoy windy roads. Currently torn between truetrac and wavetrac. Any suggestions or personal experience appreciated. It is an IRS car.
