There were 3 main photographers there, One from the BMW club, 4020 Media and LC Photography. None of which have uploaded any photo's of the BMW crash, Although I haven't asked if they actually have any.

Good day yesterday at QR, Shaved 1.3sec off my pb. Quite a few cars suffered heat related issues, 3 cars left of tow trucks with dead engines. New front springs worked a treat, Now I just need to raise the front roll center.

Today was the test for the new Aero mods at Lakeside raceway. The amount of traction was just phenomenal, I was just getting the feel for it when a slight vibration developed in the front. At first I didn't thing much of it, I felt like a bit of rubber stuck to the tyre so I gave the brakes a stab and the vibration went away. So 2 lap passed and then the vibration came back harsher, Stabbed the brakes again but it didn't fix it. This time however after each corner the vibration got worse, So I decided to pull into the pits and check it and I'm glad I did.

I found the Left front rim with 2 broken spokes and the 3rd starting to crack on the backside. The upside is I set a new PB on a broken rim but the downside could have been very catastrophic.

Wow that could of been bad. Good work on bringing it in to have a look over it.

Really got to run a high quality wheel when pushing these at the track. It's just not worth it.
