As previously mentioned, the Takeri T30 is inspired by the R30. Which I will use a Previon, with the addition of round rear lights, circles, slightly longer and low and double color.The T30RS instead will have lower front and side bumpers, different rims, spoilers and increased exhaust.
Explain better :'D
Since you are going for an R30, what about it's racing counterpart, the Super Silhouette?
Would fit pretty well in a GTA tbh. (Who knows, maybe the base R30 with tuning parts?) Just an idea ofc.
It's complicated to do but you never know.
