Lowering my car was top priority for me, that and window tint. 100% improvement in looks in my opinion and it rides just fine. I went with H&R springs as they were the cheapest. And later I cut the rear springs to lower it a little more in the rear. I can’t speak on if it improved my launch because I didn’t test launching stock vs with the lowering springs. My first time going to a drag strip my car already had H&R springs, 100% meth injection, AirAid intake, 160 T stat, SP534 plugs @ .030, UPR dual valve catch can, PP trans cooler and catless downpipes with muffler deletes.
Some ppl have rebuilt their trans with getting a lot of it WPC treated but overall there isn’t a whole lot available. My SHO is a non PP 2010 so I added the 2013+ PP trans cooler and change the trans fluid all the time and it held up.
