rear bump stops

[RickOKC]

Hey Bren, I haven't said "hi" for a long time so... "HI!" Do you still have the original shocks? Or replacement original shocks?

I met a local VXer recently and he let me crawl all over/under his VX and then he took me for a ride around the block. His VX rides quite a bit smoother than mine on the factory original shocks (and I have the softer Rancho XL9000s!) Our unmodified spring-helper-bump-stops-whatever seem to sit at the exact same position so.... I'm pondering on why they ride so differently.

Now I'm curious if brands of tires, inflation pressures & various minor differences between hand assembled vehicles may make a difference ranging from small to big.

(BTW, I think his local '99 Astral may be up for sale soon... I'll add more input if he posts it.)

tire weight? oem inflation is 29lbs according to my local NTB.

use: city/hwy/off-road = less suspension wear

Should we be using 29lbs inflation with over-sized tires?

Good question. You MIGHT even want to use less.

More seems to improve MPGs -- like you'd expect. Less probably gives the better ride. I've also run less with the vette. Figure it's better to enjoy the car and ride (loosing some tire life) than getting best mpg's possible.

I'm running 285/60-20's. Maybe a hair less sidewall height that OEM. They made the ride a bit harsher than the fluffy 285/70-16's that I bought it with.

With the former, 35psi felt about right and I got better mpg. 35psi is a bit too stiff now that I have shorter sidewalls. So really, that's probably the biggest indicator vs the overall size.
