- Yokomo B-Max4 - Tom Yardy - Southport - 05.04.2009 -

 

Ran the B-Max at Southport yesterday for the first time, we started out with the set up as stated previously given however the Southport track is a little different to Stotfold- there are a wider variety of surfaces at Southport such as Tarmac, grass, cobbles and there are a few more slower technical sections and more severe bumps, but it remains 65% astroturf.

The weather was warm again and so grip was high, we found the set up as stated here to work OK but there felt as though there was more that could come from the car, it was a little twitchy and the rear end was kicking quite hard across any rutted sections. We made some basic changes just to try and calm it down:

- Moved the front shocks to the outer hole on the wishbone
- Came down to a Yokomo pink rear spring

This really helped a lot, the rear end was much smoother, but the change to the front end was the biggest aid, the car was much more precise through the technical areas and changed direction much faster. In addition to this, the first corner was a shallow sweeper that could be taken flat out if the car was set right and with the shocks in the outer hole and effectively stiffening the front end a little I could really attack this section at fall throttle.

I was really pleased with the car again, I think this is a more effective high grip setting than posted from Stotfold and in reflection, we should have made this adjustment there and it may well have been even faster. My view heading into the season is that the pink spring with 25wt oil setting on the rear shocks is a good starting point in any conditions and the front shock bottom mounting position is a good area to adjust when the temperature or nature of the surface is varied- cooler or damp: inner hole, possibly orange front spring if wet. Warm and high traction: Outer hole.

A very versatile car.
