So did a little test looking at Non aero parts from GT Auto, wide body conversions, body rigidity and ballast on new cars straight from Brand Central.
Cars chosen were basically cheap-ish ones that covered a variety of drivetrains, no real science involved in car selection:
Ford Mustang GT '15, VW Golf VII GTI '14, Toyota GR Supra RZ '20, Alfa 4c '14, Subaru Impreza WRX '04, Alpine A110 '17.
After finding out only half of these had the option for a roll cage (part of the reason for the test), I chose another 3 cars (Audi, Dodge, BMW) and just did the roll cage update.
Part 1
Adding GT auto (non aero options), including all 3 types of roll cage
After these were added, each car got a wide body conversion, the 3 cars that had the option for a cage had the cage left fitted, the 3 cars added to the test afterwards didn't go any further.
None of the add ons/parts changed the stats for SaRGf (Stability and Rotational G figures) apart from doing the wide body conversion on Alfa, Subaru, Alpine. The only modifications to these cars are what has been listed here, none of these cars have Custom suspension, diffs etc. This is purely a test of adding certain parts to brand new cars and seeing what, if any, impact on the SaRGf is.
Part 2
The exact same cars used in part 1 were carried over to Part 2, in addition, 2 other cars were bought from brand central so comparisons can be made.
These cars then went through the same process:
BR on WB = Body Rigidity was done on the car from part 1
BR on stock car = Body Rigidity was done on brand new car from dealer (car 2)
Stock brand new (1) = A 3rd car was purchased and had stage 3 weight reduction
Stock brand new (2) = same as (1) above, but where possible roll cage type C was added
BR on above = Body Rigidity was done on this car (car 3)
WB on above = Wide Body was done on this car (car 3)
The original plan was not to involve weight reduction, however, after completing Part 2 (with just the 2 cars), I went back to my stage 5 weight reduction cars from previous test and did BR on one, and WB on another.
This indicated that there may be a difference owing to weight reduction, so car 3 was added to Part 2. This concluded the original part of the test, the data from car 3 has been added here so it's easier to compare.
The highlighted values show the only change to SaRGf that body rigidity did.
Part 3
This was an extra part added to the test, this was to compare weight reduction stage by stage between a stock car and a car that'd been modified with Body Rigidity and Wide Body.
Initially, I took one of the stage 5 weight reduction cars and did Body Rigidity to it, I then did a Wide Body conversion. I then got my other stage 5 weight reduction car and did the same, but the other way round.
I then went and bought 2 more from brand central, left one completely stock and did a wide body conversion on the other. This way the only difference between the 2 is the wide body conversion. Both were then taken through each stage of weight reduction.
The Nissan was done, "just because", I had 2 of them also and they were never going to be used.
Next up is seeing what things like BR does on used cars.
