New and need help: How to classify my factory five 818r


Recommended Posts

Posted

Hi all! New to NASA (not new to W2W) but hoping to do a lot of track time, W2W and TT with you guys next year. I have recently acquired a factory five 818r, which is a tube framed kit car with WRX running gear. Subaru 2.5 turbo 6speed rwd drivetrain.  I currently have two tunes which are 275 and 300hp (at the crank). I know I'll need to get them dyno confirmed and guessing they will be a lot lower at the wheels.

I'm banging my head against a wall bouncing between all the rulebooks and car classification form to figure out how to class this thing. Depending on a number of factors I could race in ST1, ST2, or ST3... I think. I'm open to adding weight, reducing tire size and type, de-tuning, aero, etc. There seems to be the most competition for it in ST2 or ST3 in what lap times I think it could do. I'd rather avoid ST1 because the car would be bottom of the barrel there, (and so would my driving!) 

Big questions are these two areas"

    Chassis (ST2/TT2)*

    Sports racers, “Prototypes”, monocoque race cars -3.4Other Non-Production Vehicle -0.4Not Applicable
     
    Is it a "non-production vehicle" being that it is a manufactured, numbered kit or Not applicable? 
     
    and if I go for ST3: It comes designed and built with the rear wing pictured below, is that a BTM aero mod then?

    Production Vehicle Body Modifications (ST3/TT3)*

    Modification of the OEM roof line/shape and/or windshield/frame removal -0.3Modification of the floor pan for exhaust clearance only and/or the rocker panel for side exit exhaust only -0.2BTM Aero (see 6.3) +0.4Not Applicable

     

    I'll also have to look about aero and other factors, but I'd like an idea where I should aim, and on these big starter questions. Or am I off base and need an entirely different class?

    Thanks in advance, I look forward to meeting you all soon. Car is below.

I am not an expert on ST rules, but I'll give it a shot. Super Touring is where you belong in this car, although this strikes me as one of the thorniest cars for which to interpret ST rules.  

 

“Non-Production” vehicles (ST1, ST2, and ST3 only), include all other ST series eligible vehicles including “kit” cars, purpose-built track/race cars, tube-frame and partial tube-frame conversion vehicles, and “Production” vehicles that have modifications not in compliance with Section 6.2, and will be assessed the “Non-Production Vehicle” Modification Factor listed in 6.5.2 unless the vehicle model is listed in Section 6.5.3 of these rules and has been approved to compete under “Production” vehicle status. A competitor with a vehicle originally qualified as a “Production” model may use the Modification Factor assessment for “Non-Production Vehicle” to avoid all “Production vehicle only” limitations/restrictions in Section 6.2. For ST4, all vehicles must originate as Production street vehicles unless listed otherwise in Section 6.5.3. Tube frame chassis conversions are not permitted. The Non-Production Vehicle Modification Factor may not be utilized in ST4, but additional specific Modification Factor assessments for certain approved non-production modifications are listed in 6.5.2."

 

Other Non-Production Vehicle (ST1, ST2, ST3 only): = -0.4 <--- This is what you have. The car is nonproduction, so the windshield frame is a not applicable. The car comes with a wing, so that should be fine in ST3.
