I bought this 2010 Lancer ES new for my wife and it has been a great car, except the factory paint (clear coat) gave up the ghost and so the fun begins. The factory soiler is off in these shots. Next time that you see it, you’ll see House of Kolor’s Kandy Apple Red on the top with Orion Silver metal flake, with a splash of Zenith Gold flake, on the bottom half and a Galaxy Grey flake blacking out the front grill area. Soon after you’ll hear a 400 hp turbo 4 cylinder, deep sound NOT A RICER sound. No offense to the import crowd but the Mitsubishi engine carry a deeper tone, which is what I am after on this build. Looking for the Sports Car sound. Coming shortly!
I want to thank all of the people who have visited our site, the kind remarks and who have chosen to follow the page. Radical Street Cars by RJR Racing was our first company that laid the foundation for RSC Perfomance Group Inc. That foundation, assisted by articles on our builds by SEMA, RSC Performance Group now owns and operates 4 entities, all in the performance industry, Radical Street Cars, RSC Speed Shop (rscspeedshop.com), EFI Specialties (efi specialties.com), Import Insanity (combined we store with RSC Speed Shop).
I will try to generate more posts of what’s happening with our customers and our projects.
Thank you for your kind support,
