Pretty obviously you need more neg, as that tyre is only using part of the tread. Get a pyrometer (probe, not IR), or borrow one - don't steal mine but ask nicely and I might lend it, and get a reading across the tread - that will tell you where the work is being done, even when the gross wear pattern shown has not yet shown up.

Not only will you get better wear and longer life from your tyres, you will get better times!! Win-win 8)

:mrgreen:

Thanks for the feedback.
The wheel alignment should be good and now running offset bushes in the front so now getting about -3.5 negative at the from at about -3 on the rear.
Also they are the front and rear Laft side tires so getting slightly more contact on the inner edge.

The problem has become more pronounced now I am getting consistent in the car and has good initial turn in but pushes us I get on the throttle at the apex. As the car is running 12/6kg springs (MCA Race Prime) and I know other running NC's with MCA Red's with 12/9, I am thinking a stiffer rear spring will neutralise the balance.

What arb’s are you running?

Did you fit the Goal intake? If you did, I’d be interested in the plastic part of the oem intake manifold?


Not fitted yet, was waiting for the finished built motor to fit it but may get fitted sooner for the next race. Will see how my schedule goes.
I will keep that in mind...
