Testing went well. Everything still works, and the winter's modifications all did what they were supposed to. Definitely getting downforce from the diffuser, to the point where I had to reduce the rear wing angle by 3⁰ to bring the balance back.

The CSL front ARB is also awesome. High speed turn-in is now much more positive.

Net result is that I went 2.5s faster than this time last year (2:08.79). Pretty huge gain so excited for tomorrow's race at Silverstone.
Just fantastic! This is literally my favourite thread to follow on here. Best of luck this weekend!

+1
Go Liam! Car looks mega, props. Good luck.

I was watching this. I hope he didn't get hit at 45:55, from the camera angle it looks like he was.

I too was watching this today. Liam did well not to get caught up in all that (or got very lucky). Either way, not sure what the Golf was thinking of or if they were pushed off the track by someone else?

mods look good mate, the diffusor also looks the goods, might steal that design from you

Hope your day out went well...

Looks like you did well to avoid a pretty big shunt here, hope she's still in one piece!

That's properly impressive stuff Liam - hats of to you sir! have you got any videos from the latest testing or race?

Keep it up chap, certainly for me one of the most interesting threads on the forum these days!

I'll write more later, with video, but here's the short version.

Car was fantastic. Class pole, win and fastest lap.

Lap one, turn two was perhaps my luckiest escape ever. I saw my RHS wing mirror go dark and turned out of the corner as a Golf came shooting across the grass. Just the lightest of touches...

Feel sorry for the Cayman owner - he got shoved and baled 'for safety' only to be hit again by the golf!

Great reactions though Liam

I thought it looked like you got a touch. Hell of a reaction to avoid a harder nudge though - very impressive!

Also great news to hear all the hard work you're putting into the car is paying off with wins!!! Great to see someone campaigning a Coupe too, such a rare thing on a race track

Great result Liam. I've just watched the compilation video Malcolm Edeson has put together of the lap 1 incident...code brown! Great effort to avoid some nasty damage there.

A 1.05.6 lap is pretty decent around the National as well!

That was lap 2 with an almost-full tank. 1:05.2 in qualifying (not a clear lap)

The car is good for a 1:04 in ideal conditions.
