I reckon I would have gone close to breaking 2:40 with 5th gear, that was my original goal for the weekend. Top speed should have been closer to 230 on Conrod.
Suspension setup is pretty basic at the moment, getting the suspension setup right is still on my list
Also the tyres I run are used, ex Mini Challenge tyres. So although they are slicks they've already had a fair bit of use before I get them. They're still good for a few seconds over semi slicks though, depending on brand and condition. With new tyres though I reckon I'd get another couple of seconds again, but my biggest problem is still lack of power. The car way out handles it's power capability.
Also although I was pretty happy with the 2:45.3, it was by no means a perfect lap. There's still probably at least a couple of seconds just in getting every corner right.
