Something made me want to go all in and do this conversion. I haven't seen it done before so I can't say if it's going to work out but from my eyes, it looks doable.
Basically I'm taking the original steering knuckle out and replacing it with the very different knuckle assembly that comes as an option on some much newer GM FWD cars.HiPer strut info here
"HiPer Strut utilizes premium, technologically advanced engineering to improve ride, handling, and steering in the front-wheel drive vehicles. Specifically, the technology delivers the following benefits:
Reduces torque steer
Boosts vehicle response to tire variation and imbalanced wheels
Provides more linear steering
Enhances driver communication
Improves isolating impact from bumps and rough surfaces"
While i'm going through the effort, I'll go ahead and do a coil over build too. In some ways, it should actually make it easier.Original coil-over thread
I'll just post about it as I go and make discoveries but I'm in planning & research stages now. I'm actually more concerned about the coil-over parts than anything because I don't have a lot of experience with it.the primary things I know I need to make
top strut mount plates for coil overs
simple adapter sleeve to connect coil over body to hi-per strut
round joint to replace the ball joint on the original control arm to connect to bottom of hi-per strutparts needed for hi-per strut
complete hi-per knuckle/yoke assembly
outer tie rod ends for hi-per strut

you can kinda see the need for a different outer tie rod end. The connection point is in a different location and it has to arc around to clear the yoke during turning
just eyeballing it, looks like the barrel joint I need to make is going to be positioned right over the 3 bolt holes for the stock ball joint. If that holds to be the case, it'll be a nice neat compact billet piece.
The top of the hiper knuckle just has a diameter machined in there for a body to go in and clamp tight - super easy
back of stock knuckle
back of bare hiper knuckle
Thankfully it looks like the wheel bearings can be swapped which is necessary because they have different splines and speed sensors - that would have been real trouble if they couldn't swap
top 1998+ top mount
bottom 1997- top mount
I figured they'd at least have the same bolt pattern but nope. Oh well
Originally I was thinkin of setting this up on my green 97 riv so I can go nuts with it right off the batt but instead I'll probably just do it up on the currently stock 99 since that's where it'll eventually end up. I do plan to make the top mounts with at least camber adjustment but I refuse to cut the strut tower opening more so it'll probably only be a small adjustment range.
