Yeah what aloha said. To get an F30 to handle like a Type R, you'd have to spend abput 5K USD.
Note that ARBs are away bars. You can get a set for 4-500 but the labor will likely be double that.
If cost was not a problem:
- sway bars front and rear
- coilovers, best matching of spring and damper
- lsd
Also to note that with the away bars you could possibly get away with separate dampers and springs, but it would require more work to get them matched compared to buying coilovers.
Tbh if you want Type R handling you'd be better off getting an M3/4/2 with EDC. Trade in the F30 + money you'd spend on an upgrade.
Your other option is to throw all the mods listed above in a bag and keep the F30. Parts are far cheaper than the M market.
