Back to back the alloy chassi was 0.3s slower on high grip asphalt with the setup adjusted for each chassi.
The alloy chassi was more stable in the high speed sweepers noticably less tendency to traciton roll but lacked mid corner speed on tight corners particular hairpins.
The track layout had 7 hairpins and 2 sweepers.
On a high speed high grip sweeping track the alloy chassi would do well.
Weight difference was about 35g but I was measuring a used carbon chassi.
