The rally is to be held on November 15, 16, 17 & 18, mainly in Galle, but the start/finish and maybe a competitive stage or two will be held in CMB. Anyway, this is a different type of rallying to what Gaya and the guys had on Sunday. While those events, known as TSD Rallying, focus on accurate navigation and feature lower speeds, the rally in Galle will be similar to the WRC, with flat-out closed courses where the winners will be judged on outright pace. This type of rallying will be good for cars like your Evo, which is why I'm encouraging you to run.
By the way, what colour is your car? I go towards Attidiya quite often but haven't seen it.
