I didn’t need a special tool for the LCA, just impact the nut and that’s it.
As far as ball joint separator, I tried mine but couldn’t get it to work for the caster bushings, so wound up just using a family members floor press.
If you're referencing SPL parts, NVH is negligible and almost non-existent. Primary increases in NVH will come from solid differential bushings or motor mounts. Pretty much every other SPL bit will sound stock.
Main benefits are the resounding increase in steering feel and adjustability.
You'll have to get a trim tool set as well to safely pry them off. Just order a set off ebay, amazon, or harbor freight and use a microfiber towel in between the tool and the mirror. Easy removal and install, maybe 10-15 minutes a mirror.
IIRC, roughly 30-35F in similar track conditions. Tried to find previous data logs, but can't seem to place them right now. Next track day isn't until the fall (traveling), so I'll have to get more data then. Cooling was substantial though with no aftermarket heat exchanger or side radiators.
Didn't even consider the ECU at all. Good point. I wonder what if it'd be possible to tune the level at which power pulls on an oem ECU.
My IATs are good for now with an AMS intake manifold, but they can always be lower. Ideally, once I decide on what hood venting to go with, I'll be curious...
That’s awesome. Let us know what the organization is. As a currently serving member, I’d love to keep an eye out for their events if they have anything close to my region and make it out to one.
I’ll attempt to answer most of that.
1. Nothing required to hit the track, plenty of stock supras successfully doing track days. Recommended to do, but not necessary, would be brake pads and brake fluid. Drivers mod and just getting out there is the best thing you can do.
2. Tools necessary...
Take your time. Nut and bolt check everything after installing. It's a fairly straight forward install and takes maybe a couple hours. Make sure not to damage the ride height leveling sensors during the install.
Picture I used for reference of correct alignment of the rear ride height level...
