Getting closer Perry!

Can you do anything about the obvious asymmetry in the launch, where the passenger side front wheel lifts much more than the drivers side. A torque tube maybe?

You dont want to do that, it is all part of a cunning plan to reduce friction losses , only 3 wheels in contact with the track, 2 driving, 1 steering!

Hmm, I like the idea of both steering-wheels being in contact with the tarmac!

Nah!!
Its more fun this way Chris :)

Since I tweaked the rear suspension I dont have to add much steering input on the launch now. Even though she is still cocking one leg ??

I forgot to add that I jhave a bad brake bind that we discovered on the second run on Sunday. I coasted in drive down the fire yp lane and popped it to neutral at about 10mph. It stopped quite quickly on its own??

I havent had time to find out which brake is binding though. I'll have a look over the weekend.

Hi Chris
In my case I found that the rear axle mount for the top link on my 4 bar had broken on the drivers side - and I then went for stiffer rear springs, so later on the car was launching like thisImage
