Nice motor EL, like what you've done so far
As for tyres, I found the Falken FK452's pretty poor tbh. Even in the warm, dry and on smooth roads I'd get wheelhop on hard acceleration from low speeds on my unmapped car. Wet grip was very poor. I went for the Vredestein Ultrac Sessantas which are much better. That said I've had them since late April last year and they're definitely past their best now. They've had very little sympathy from me since I had them fitted but I'd expect slightly better wear rates than this.
I'm thinking about the Toyo T1-R's next time as they're a lot cheaper than the Vredesteins and seem to be easier to get hold of.
