510 HP Kia Stinger with BestLine

Robert K  Verified Buyer 07/01/19

Using BestLine for years and now in his new Kia 3.3 liter Stinger with twin turbo's, Borla Exhaust, Intercooler and blow off valves. 

Rolling on IZ racing wheels, Michelin tires. 

Stopping power controlled with drilled and slotted rotors. 

Robert mentioned that he doesn't like his exotic powerful motor to experience "dry starts".  I think we would all relate and agree to that.

That's another reason he is using Bestline. 

Great job Robert and thank you for sharing this beautiful car with us.
