Spring is just a spring - if you feel like you have oscillations then it's the damper no damping enough, spring has nothing to do with it (other than it returns the energy in it stored during compression but any spring will do that). Progressive springs with higher rate will likely bounce more...
You wouldn't disturb them - hubs (or specifically bearings) are a wear item - did you check them for play while you were doing this ?
This would have been good opportunity to retighten the nut and add jamnuts that OP Mustang sells. But I get it - still think no reason to be afraid to take it...
He did out of the differential - why not just push the axle out of the hub instead ? Don't think anyone with think to remove the knuckle together with the axle if that was the intent of getting axles out of the diff.
You are massively overthinking this (as many here) and yt absolutely made you paranoid - those people want clicks to need to create something that at least on surface is "interesting", for example "
"One big thing you didn't know about Coyote first oil change !!1!"
The way to think about -...
More of an issue with the front is that one wheel is toed in and other toed out. That would bother the hell out of me even if not noticeable at steering wheel.
Since I just changed the oil yesterday - my engine somehow holds full 11 quarts without any coolers - do you remove the filter when drain plug is still out ? In my case that causes decent amount of oil to come out of the oil pan the moment i take filter off the threads (when i completely remove...
I think GTD had either RT660+ or RZs, ZR1 was most definitely on Vitours, what combination they ran that day I have no clue.
I think the OEM tire rule applies to locals only
We had recently GTD and ZR1 (not ZR1x) at National SCCA autocross event at Grissom AFB. Both were on 200TW index tires (so street tires, nowhere close to Trofeos or Cup2s). GTD wasn't even in the same zip code of the ZR1 (two different drivers, both very good).
Don't think you really need anything - slot in the camber arm mount has so much adjustment that it may allow for that much camber. Someone probably pushed it all the way in and called it a day (+ maybe lowering spring added some extra).
It looked really pretty, wish shiny carbon parts and really good looking paing - It had a bunch of ppf in places.
Owners also brought it to Toledo local previous weekend (I know them pretty well, they typically run 28 so we're always neighbors in the grid) so they're not shy about running it in...
