Since Ronald Völker's World Championship win last August, the team has continuously worked with the #BD8 Rear Toe Control (RTC) System (Part no. B8-RTC1) at both indoor and outdoor races. More often than not the RTC is preferred over the standard configuration, and when tuned correctly for the track conditions, it can provide both improved rear grip and cornerspeed. Today let's take a look at some recent setups to address one of the basic tuning aspects of RTC, inboard vs outboard toe-in. (We'll save toe-gain for a later tip!) Using the suspension mounts to increase rear toe-in (inboard toe adjustment) generally results in more overall rear grip, but with a significant affect on wheelbase (making it shorter). On the other hand, using the knuckles to increase rear toe-in (outboard toe adjustment) results in a smaller increase in rear grip, but also a smaller affect on wheelbase. First take a look at Naoki Akiyama's winning setup from the Speed King Tour race this past weekend and you will see that he used 2 degrees of rear toe-in, set entirely with the inboard mounts. Compare this to Nicholas Lee's setup from the Reedy Race the weekend before, where Nicholas used 3 degrees of rear toe-in, set entirely at the outboard knuckles. Also notice that while Naoki used 2mm shims in front of the rear arms to fully lengthen the wheelbase, Nicholas only used 1mm. Despite Naoki using more shims to lengthen the wheelbase, the wheelbase on Nicholas's car is still longer, which gives you an idea of the significant affect on wheelbase due to inboard toe. Both of these setups were used on medium-grip outdoor tarmac tracks, with great results by both drivers. Despite being more complex to tune, using the RTC system offers you the choice between inboard toe, outboard toe, or a combination of both to obtain that extra bit of grip and cornerspeed. Get out to the track and see what feels best for YOUR driving style to turn in those fast lap times!
