Is there any adjustable,mechanism to allow the seat bases to tilt at all? I'd like to tilt them back a little to support my thighs, but also it needs to be adjustable to suit a shorter 2nd driver.

Because of my height, I definitely don't want to raise and lower the whole seat, in fact would like to tilt the base up at the front.

Thanks

 

I was also wondering how and if this was possible.
