Ok so i tried as many of the changes as i could at a club day last night. ANd i am still not really sure what is happening.
Heat 1: i went out with my stock setup (shorty battery, rest pretty much standard) fastest lap: 12.85
Heat 2: swapped to the 10 degree caster blocks,
The car felt a little bit more aggressive, it would cut into the corners a bit quicker, but i felt like i had to nurse/fight the car around as I usually tend to set my cars up so they feel safe, lap times were improved though. Fastest lap: 12.54
Heat 3: fitted the 22 2.0 hubs, drive shafts and hexes (with the small spacer that comes with the drive shafts) and mounted the shocks on the front.
popped a drive shaft in lap one
Heat 4: fitted the 22 2.0 wishbones.
The car did feel like i could push it a lot harder with this setup. But i think the biggest telling point is that i managed to drive for an entire 5 minutes without making a mistake (or popping a drive shaft
). Slightly disapointed that the lap times didnt improve! Fastest lap 12.52
Final
popped a drive shaft on lap 2. Marshal fixed it, so then i went on a mission to destroy my fastest lap time. fastest lap: 12.32
Summary
I am pretty divided if the changes made that much difference for me personally (for my driving style), I do like the idea that the 22 2.0 back end makes the car wider, so i will probably stick with it, that's if i can actually solve the drive shafts popping out (do others run the entire back end with the wishbones?). ANy suggestions welcome, i tried shoving an extra spacer on the inside of the hub, but then i couldn't get the drive pin in.
I might try swapping the 10 and 15 degree hubs one more time just to get a feel for the difference. I still need to do a lot of playing, i run two many cars to really appreciate the subtle changes that its probably making.
But on paper, the hubs made the biggest difference in lap time, but it just made the car a bit scarier to drive. the rear end made little change in lap times, but the car did feel a little more planted, and crucially, less mistakes.
