So I wasn't please with the height in the front, so I bought the Canuck motorsports 2.5/1.5 spring package. I replaced the fronts only, so technically, my springs are 2.5/1.7, which is a nice height. It's a subtle rake, and I'm pleased.
I also didn't like how my new TSW wheels had 15mm less offset, so they weren't flush like my GT500's. I bought 1/2" spacers for more poke, but that required longer studs to be installed as well.
All in all, it was a pretty big project, but I'm happy with how it turned out. I did it all myself in the garage.
Getting started. New springs in the front:
Pulling the new studs in:
You can see the longer stud length here. PN: 610-323.
Here's the spacers. PN: 44121.
Overall, I gained only 1lb per corner with these. I was hoping it wouldn't be too much, because I lost ~7lbs per corner by dropping the GT500's.
Here's how it looks now:
