Hey mate, welcome to AGT!!
Its a funny thing when people jump in to a SP, they all fall in love.
If you really want to make it fun, up grading the suspension its the biggest and best mod you can to to these chassis, apart from chucking a turbo on them haha.
But wheels your in luck, have the same 5x114.3 stud pattern an most Japanese cars, it gives a nice big option of wheel sizes and choices,
The biggest issue is the guards are not very wide for low offset wheels,
Idealy 17x8 +40 is a about a perfect size for these cars, with a 205 40 r17 or 215 40 r17 tyre.
I had mitsubishi evo8 wheels on my car, 17x8 +38, they were super flush fitting and looked agressive, and i was quite low as well, but guards were rolled and i had fairly stiff coilovers.
Make a build thread and we can talk and discuss more on there, that way you will be able to keep track of everything
Again welcome
