Yes, front shocks are the new pair that was on eBay for $150.. I had those grooved for the shocks

I need too get good pictures but the front is lowered 1.5" and the rear (still has the fiberglass spring) is lowered 1.25"

Hmmm, Another future project.

Thanks.

One major concern I have over supension mod is that, based on what I understand, changes in spring rate and/or roll bar can result in under steer/over steer characteristic.
Will you be testing and tweaking?

probably tweaking, I need to finish my poly bushing install and get the car aligned.. then I will see how well it does

Forgot to post some pics of the air filter bolts that Carter made - hope this works

how is the ride in comparison to before

I went with 400 front, and 275 back and the ride is OK, but I think the F1 supercars are the "problem"

biggest thing I ran into is lowering the car too much. not good. I think I was bottoming out the shocks as I busted a fx3 controller

I'd like to someday upgrade to a better shock and maybe lose the fx3.

more hassle than it's worth to me.

nice setup!! that's a great way to go as coil overs are expensive and you really engineered a bargain conversion

FYI, DRM grooves the shocks pretty reasonable for the snap ring. a local machine shop quoted me 200 and DRM was 15 per shock as I remember (call randy)

as for tuning, it's hard to "out engineer" the Gm engineers and the stock suspension is actually a pretty good compromize for street driving, but the coil overs definely help

there is a bit of hassle getting them on there and setup, and because I'm so lazy I wouldn't have done it again knowing what I do now, but I mostly didn't like the expense and the harsh ride. there is no doubt the car is "glued down" better and much more stable at speed around corners.

my c5 has coil overs, but rides like a cadillac in comparison

alot of that is the EMTs though, when I bolt on my "race tires" with the a molds, ride is much better.

Ron,

How low did you go? I have not noticed if it bottoms out, but the stance it very close to what my 89 was.. it seems much better.. as for the ride, I have not driven enough to say how it really is.. I have one more component to swap, then get an alignment.. Not sure i will get the new parts on this weekend but I am hoping to
