Advice for driving is to get a sim. Find a cheap g27 or thrustmaster on marketplace and do all your learning in the sim. It's going to be infinitely faster and cheaper with the added benefit of probably linking on your first track day. As far as these cars in specific, they can drift bone stock. Don't let anyone tell you they need x and y to get sideways. Get a bucket seat and learn to drift it bone stock and upgrade it as you go.

Drifting is a style sport. Make your shit stylish. This chassis has been out long enough to have countless sources of inspiration whether old or new.

Also, you can be financially responsible and have a cool car, it's just a slower process. I know from experience it can be of demotivating watching from the sidelines and seeing someone have a bone stock car one year and a fully built car the next but slow progress is still progress. Maybe you'll only be able to afford one big thing per year just make sure it's in the correct order. Don't buy a nice kit on stock wheels lol..
