Lower it atleast 1.5in all around for far better cornering.

Getting quick struts will raise the car up some and make it float and body roll more. I'd just buy some KYB struts and some lowering springs, new mounts and you can get that for around 500 bucks. Struts are around 240 and new springs are 180, then it's just the price of struts mounts.

I'd go with a 180 aswell, engine works better when slightly warmer. Run 91+ octane and perhaps add a 3in downpipe or just spring for headers.
