9 Will you need to buy a tech service & measure your car for these packages? For packages level 1-4, yes, Tech Service #24 or #40 is required No production car from the 50’s to the early 90’s comes from the factory with the suspension mounts exactly mirrored from side to side. None. Nadda. Ever. The factory production tolerances are 1/4” on every point & they add up We typically find the cars do not handle the same left & right because of this So after you measure, Ron outlines minor changes to match up the sides While we’re there, if you’re game, we might as well make a few improvements When modifying the lower control arm bucket holes, Ron will guide you on how to match them up … and how to get some improvement as well The exceptions are C5, C6 & C7 Corvettes as they are within .030” & need zero modification Why should I do this measuring & LCA bucket hole corrections? So the car will handle consistently left & right To increase stability under hard braking & initial corner turn in To increase grip … front grip primarily … but total grip overall To make the turn better … and carry more corner speed … comfortably What about replacing the factory clip or the whole chassis? Ron designed the suspension geometry for Speedtech’s new ExtReme front frame & suspension packages as well as their full chassis. The geometry & performance of these are on par with our TA2 Track-Warrior front suspensions … and they BOLT ON ! Where available, these are awesome performing Autocross packages: No need to measure your car for these packages / The geometry is already optimum Level 5 utilizes the Speedtech ExtReme front suspension & rear torque-arm package with a Ron Set-up & “Secret Sauce” valved shocks tailored to your goals Level 6 adds Zero Stiction ball joints, watts link, 3-piece rear sway bar & floater rear end Level 7 utilizes the Speedtech ExtReme front suspension with a Track-Star TA2 3-Link Suspension with double adjustable panhard bar & floater rear end Level 8 utilizes the Speedtech ExtReme front suspension with a Track-Warrior TA Decoupled 3- Link Suspension with Quik-Adjust watts link & floater rear end Can you track the AutoX-Star & AutoX-Warrior stuff on road courses? We do not recommend it with the Level 1 AutoX-Star packages o The spindles, hub bearings & flange axle rear ends were not made to handle the high G- force loads of road courses o Especially Level 1. It is a safety concern Level 2 AutoX-Star & Level 3 & 5 AutoX-Warriors are better o These packages do have better spindles & bearings, but still run flange axle rear ends All Track-Star & Track Warrior packages run good spindles & hubs with floater rear ends o These are designed up to the task of the high G forces seen on road courses Key Information
