volvo performance
 

Wanting to do something to upgrade my '11 C70 T5 performance. Any suggestions?

There are a lot of things you can do, but it really depends how much money you're willing to invest. A software tune is an absolute must. I would consider Shark or Elevate over Polestar, better performance gains and a lot cheaper.

Upgrading the downpipe and exhaust will also free things up. Intake, inlet manifold, suspension. There's a lot you can do.
