Hi there,

I'm creating a build thread to document what I've done to the car in the past couple months in case I need to reference for historical reporting or in case I sell down the line (hopefully not haha). My goal is to occasionally race this car in HPDE or Autox sessions, but I took @Asbjorn advice and I joined a local indoor/outdoor go-karting league. So this car will just be an excuse for me to practice photography and video most of the time since I recently picked up a camera. So my frequency of racing this thing will be pretty low, like 2x or 3x a year. Hope to update this thread once in awhile. BTW, if you're in NY area, I suggest joining the NYC Go Karting club on FB Group or Meetup, it's pretty cool, 3 - 6 hours worth of seat time per event, $60 for indoor or $300ish for outdoor, karts go to 30mph to 50mph depending if indoor or outdoor. Don't have to worry about maintenance before/after each session unlike HPDE or drift events lol.

You can see I took ideas from @Asbjorn @berns @MDORPHN @JimboFresh206 on this forum

Pictures will come in within the next week or so.

  9. Custom Tuning from @Twisted Tuning - March or April 2022 depending on the weather to head Upstate NY
  10. 14K rear swift springs (not sure if my rear suspension will compress, but we'll see if I need a stiffer rate) - Unknown
  11. M3 front and rear control arms or SPL fronts + Megan rears, not sure... leaning towards M3 for simplicity's sake of getting a bit more front camber and for updating bushings all around. Since I'm seeing more people in the EU drift this thing, I'm hoping more innovation happens in this area - Unknown

  13. New winter tire/rim setup, looking at Kansei rims to plow snow with - Unknown
  14. Manual or DCT transmission swap (hopefully not, but considering it... especially if I get a second car) - Unknown
There are other things I'd want to do to the car, but I'm trying to save for a SUV or a truck like a Honda Passport, 4runner, but the California in me is open to a hybrid RAV4 but it can't tow haha.
