Personally, I'd go ct20b/Blitz K1-380v/PE1919T (all bolt ons), if you weren't prepared to pay a good $5k to get all the supporting modifications.
Unfortunately I'm all sold out of CT20b. No one wants them for ages, and then everyone wants them all at the same time hahaha.
I will have a few more coming from japan ~$500 in August.
PM me if you'd like to reserve one.
