Thanks for the reply dwnshift!
i'm actually beyond stoked that you said you might have developed some delrin bushings. for reference, here's a picture of the front suspension and the bushings of interest (please let me know if there are any others!)
1. this is actually giving me tire wear issues cuz it's starting to
give alot. this badboy seems to move twisty but also up and down. spherical reccomended?
2. spherical is definitely recommended for track (because it moves in 2 axis). can get away with delrin/poly for dd
3. delrin/poly should be fine here
4. not a bushing but a ball joint. the 350z had issues with these guys i believe. are they replaceable?
let me know of your thoughts!
