Just a quick ask really.

At the moment I've stripped the complete rear interior out of my ST170 due to it need a little welding done. Now due to a noticeable performance increase I think I may take the remainder of the interior out, but wanted to ask about lowering the car.

The car at the moment has obviously gone back up in the air on the rear, and the rake is far more than it was before, but if I fit a lower spring set along with new shocks then I feel it will just put it back to the original ride height.

Are coil overs my only option ?

Also how easy is it to work with carbon, as I thought about getting some sheet and cutting it to make flat panels to go where the door cards used to go. I've heard nightmare story's about carbon splinters and edges etc.

As an alternative has anyone used perspex.

Thanks for any pointers
