With the G4, I got 3:14 Akina earlier at Mat's lounge, it had some slow section as I was chased by his monstrous sized R34 GTR on my rear view

The Spitfire was around the same time with a clean run, maybe faster, I am still tuning it, I lost my updated settings when I used it against Solid's EG Civic last week

If it can keep the EG of it's back for a while, I think with a good tune and driver, the Triumph would be quite fast.
I have both of them on share, please try them before deciding if they are allowed or not
