Spring (Finally!) Update - Took the car out with Swift Springs, mild RMM upgrade, Cobb OTS stage 1 tune. Did a test and tune on OEM tires, and then an autocross on last years worn Falken 660's.
It was as you would expect. Fun factor increase due to the flatter cornering, still trouble getting the power down and a bit of wheel hop. First runs were very tail happy even at stock pressures, learned to "slow down my feet and speed up my hands" and got some decent times. Organization I was with has limited classes, was faster than the all the cars in my previous class, gaped by 1.5 seconds or so in the new class by the leader but a decent showing. So overall glad I'm trying this out - never going to Nationals just having fun.
Keeping with the budget build, just put in a Whoosh 2 point brace today (not a bad install if you take off the wheels to get the bolts loose in a much more comfortable position). Camber bolts next, not sure if I'm going to run them at full yet. Probably run it like that a little, then put on the Fresh 660's on 16x7.5 wheels if I don't find some 16x8
Further in the season, fit the upgraded IC I have in a box and stage 2 OTS tune (probably upgrade to a more custom one later).
Thanks for all the advice, open to hearing other suggestions.
