Weather closure 1/21.
Edited to reflect current plan:

Due to winter weather / travel conditions and school closures we will be closed on Tuesday 1/21

We will open late on Wednesday 1/22 and we are playing it by ear and will make a call that morning depending on travel conditions and availability of power and water.

Please stay safe, drive safe, and pay attention to your tire pressures and tire compounds! If you have Ultra High Performance Summer tires please check temperature operating envelope for them. Many of them are not meant to be used under 40F and some cannot even be MOVED under freezing temps and need to be above freezing for 24 hours before it is safe to move the vehicle again. If you tire is an All Season Tire you generally do not have to worry about these temperatures, although you can obviously expect lower pressures in the cold and reduced traction.

If you are a DDPR customer that is reading this and you are unsure of your tires performance envelope you can call or email us today or Monday and I will be happy to help you find that information! To do that, please get the tire brand and model from the sides of all 4 tires. (Ie: Michelin Defender or Pilot Sport or Toyo R1R etc)

Just about done with a really neat restomod.

Cruise control through the link ECU using the DBW throttle. Full Ceramic coated exhaust with additional heat shielding, new Vintage Air heating and cooling system with custom lines, singer 190A high output alternator
