I 2nd this, I was looking into the AIM dashes myself. I think the racepak is a cool dash but it screams racecar and it a little outdated compared to other dashes out there.
I don't, I haven't installed it yet. Car is undergoing a new engine build and a lot of other changes. I'm debating whether to keep the stock cluster and use the MXP as a secondary display, or just use the MXP only. I started a build thread you can follow:

This is where I got my dash from: AiM MXP Strada 6" TFT Dash Street Icons, CAN Harness - Pegasus Auto Racing Supplies
I added a backup camera as well: AiM Rear Camera for MX 1.2 Series Dashes - Pegasus Auto Racing Supplies
Race Studio 3 Software: Aim Software | Aim Technologies
You can also add a bunch of other accessories to increase the dash's functionality because AIM has its own CAN connection.
