Default Aluminum Chassis Plates

I would like to hear someone highlight the benefits of going to an aluminum chassis plate vs carbon fiber. I assume its about putting more weight to the ground and lowering the COG, but I would think that it would be more prone to tweak issues and less likely to return to its original shape if hit hard enough to distort it.

Several companies are releasing Aluminum chassis plates, and several of the locals are laying down some fast laps with them, but they were fast anyway.

I have both an awesomatix and xray t4 '14 that I run aluminum on. It's very responsive and consistent to me. They are far more durable than I originally thought, and trust me I've done some solid durability testing. I actually end up messing with tweak less often now than I did with carbon, but I haven't tried either of them on asphalt. I've run mine on medium and higher bite carpet only and love them both.

Thanks that was what is was looking for. I wonder how they hold up against scratches on Asphalt. Did you use an aluminum plate from X-Ray or Arrowmax or someone else?

On the awesomeatix that car is so alien to me. I am not going to pretend to understand it.

Ricky and I both race in Dallas and we are using the XRAY alum. He also has the arrowmax, but I dont believe he has used it yet. I have found that it stays flatter around corners and stays more consistent. They are very durable as we have both put some hard hits on them. I usually throw it on a tweak station after any hard hit, and it has stayed tweak free much more then the carbon chassis has after a big hit. I had the chance to run it on asphalt this past weekend, but chickened out as I didn't want to scratch it.

Same here on the chassis, I didn't run mine on the asphalt because i didn't want to damage it.

Have you guys had much chance to run it on medium or low traction? I've been told its only good on high traction. And the one time I saw it run that was true. But there wasn't much time for the guy to test any changes out.

Our carpet track can be considered to have medium traction. Sometimes it sucks and has crappy traction

I think it's more about how the Alu chassis can flex better than the CF chassis. The lower CoG probably helps too but to me the flex is more consistent that CF.

We all use Springs and Dampers, tune them and so on. But over every little bump the chassis is also flexing and working as an torsion spring. And also it has a very little dampening effect.
Maybe Aluminium has more or less damping effect and therefor can increase grip especially on more bumpy parts of the track.

A serious scientific approach would be interesting.
