Loud RT was purchased in October of 2013, new in Fremont. Originally I wanted a Jazz Blue Pearl car with certain options, if not that, black, if not that, white. I compromised on a white with red hood to fender stripes, or "war paint" as I like to call it. After a few weeks, with the 49ers doing well during their regular season, those red stripes grew on me, and really helped form the personality of the car. Over the next few months, I became more and more comfortable with the car's limits, in stock form.  However, as summer approached in 2014, my OEM parts just couldn't keep up with the my needs and the first parts to be replaced were the stock brake rotors and pads. I did a bit of research and settled on StopTech cross drilled rotors, and EBC Red Stuff pads. These, combined with a Petty's Garage double strut-tower brace helped keep the car under control on my favorite back-roads. Next would be my suspension components. I spent a lot of time going back and forth considering all of the options and finally decided on the Eibach Pro-System Plus. This suspension kit includes their pro-kit springs, shocks, struts and sway (anti-roll) bars. I also required the Eibach pro-alignment bushings for the rear lower control arm, as well as the Eibach Pro-alignment front upper control arms to dial the camber back to an acceptable alignment. Right after that was bigger wheels and more performant tires. I bought a set of Boss 340 wheels from a friend in the South Bay Challengers Facebook group, and got some Michelin Pilot Super Sports in 255/45R20 on all four corners. Again, my research has paid off. With handling, grip, and brakes finally matching up to the HEMI powerplant, I had my first track-day experience at Thunderhill in April, thanks to Speed Dynamics track events. I had the time of my life and learned a LOT about my car I didn't know was possible. First, Michelin Pilot Super Sports have a very linear grip fall-off. I learned tire squeal isn't your car telling you you're about to lose control. Second, 4000+lbs is a lot of fun around a race track, but less weight is more fun. Most of the effort entering and exiting turns is fighting the weight to and from the apexes. A lot of time is made up between turns though as long as you have the right line coming out of them. My second track day was at Buttonwillow Raceway. After a few sessions I came to the realization that I can't be much faster in Loud RT as it is today, without losing control somewhere along the track. Since then, I've thought a lot about trading up to a more performance oriented car or taking Loud RT to the extreme, by cutting weight where I can, stepping up my suspension and braking components, and also looking at more performance in the form of a stroker kit, rather than a super charger to continue saving weight. I like to spend a lot of my free time on Mines Road, Del Puerto Canyon Road, and Palomares Road. I love driving on back-roads in general.
