How did you find the balance from side to side?
My Echo has nearly perfect weight distribution on the fronts, but the rears are 30 kg different. And the heavier side is the side with the muffler (but no fuel tank).

When we first rolled it on the scales it was 100lbs light on the right rear, with near perfect front weights. I guess our 2.74lb Coast Fabrication muffler took too much weight off of that corner.

We have been able to improve the weights a bit, but we are trying to be really careful about overloading the left front - Road America is nearly all right hand turns, and we don't want to burn off the left front tire at the Runoffs.

Hot off the presses... Just got a finished copy of the October issue with the Yaris intro. SCCA members should have the issue in 7-10 days.

Just got the call from Toyota... New VVT cam gear installed, and we are fully operational.

Back to the dyno for more power.

Standard replacement. The old one was frozen.
