Very happy Mazda Rx8 Owner :)

So I got a brand new engine from warranty for about 100$. Replaced the clutch in there with a brand new one. Did ignition coils, spark, and wires brand new (did that myself, and I'm a noob whose never done that before, with Version "C" coils, and NGK wires and plugs) and it runs amazing now. If you didn't know before. my engine compression was at 3.2 when i bought it like 2 months ago.... when it was suppose to be at 8.9 (minimum 6.2 i believe). So Now i'm starting to do some interior stuff. Anything you guys should I think i should do mechanically maybe? or do you have any cool visuals mods I can start off with that aren't to expensive besides the LED Lights I'm going to do next. Thanks :)
