Default Coil over or air assist?

Well, my rear end on my car is still a little lower than I'd like. I was wondering what you guys thought of air assist/coil over struts/kits. I found some kits for decent prices, I am thinking maybe I should go with air assist but I know nothing on this matter. Also what brand and stuff do you recommend...resonably priced of course. One air assist kit I found was $65.99 I think that was a set of 2. Thanks guys!

nononono

you get a new strut assembly similiar to the SSEI ELC struts, and then get an adaper kit so you can inflate/deflete the struts anytime you need to

ill let Jrs chime in since he was the pioneer of the setup

Thats an interesting looking set up tho you have to admit...

Yeah I adapted the Air struts to the rear of the 95 Bonnie... It was well worth it... $71 per air strut, and $5 for the line kit to adapt the air struts... I have hauled 400Lbs in the trunk with the rear level<--- 400 Lbs is a bit much I know... Car still drove good and level... Also gave the rear a more solid ride quality... Also if you make any changes you may want to consider changing the 14-18 mm sway bar to the 21mm sway bar...

I have had the rear air struts for close to 2 years now... When and if I ever get around to it the 91 will have the same set up...

Good Luck

Ok, so what do I need to do to adapt them to my car? Also where can I get these struts. I definitely want to do this, my car is soft and low in the rear so this sounds perfect for me. I learned my lesson about cheap struts after these Gabriel ones, not even a year and they feel like they're shot.

OMG.... Don't get me started on those Gabriel struts... And thats because they are shot BTW.... Junk, junk, junk, junk.... After way less than 2 years 2 of my Gabriel struts were dead... Pulled the right rear off and it did nothing... Told me why my handling was gone...

Upgraded to monroes, I have never looked back... And they have held up 100x'* better than the Gabriels...

Ok here are some pics...
Below is the Monroe Air strut... I believe this is a bit better than the OEM unit...


This is a pic of the Line Kit to adapt air struts to the non air suspension


The strut installed on the car... Look to the left and you'll see the wire loom.. I used that to protect the air line...


Here I drilled holes large enough for small rubber gromets to feed the lines through... I did this for both sides at the rear of the strut... The pics should give you a general idea for the location of the holes..



Here is the T fitting for the lines.... I ran the lines behind the padding and had both lines come out at the location pictured here.... Later I drilled a small hole in the plastic( not too far from my hand ) and installed the T fitting there so that it was easier for me to check the pressure and add air when needed... I usually run at about 20 psi most of the time... When you get to 30-35 psi, the rear end goes up a good bit and the ride gets a little brick like...


Hope that helps... One of these days I'm going to have to Techinfo this... I'll have to do this to my 91 and get a billion pics...

Also A small note, I noticed that the H body cars with non air suspension had a spacer on top of the strut that was sandwhiched between the top of the strut and the bottom of the strut mount... I later had to go back and remove them as every car I found with the air suspension did not have the spacer... I have had no problems...

Well that doesn't seem too awefully hard I don't think. How do you fill them? Will keeping the PSI equal in both struts keep my car level? or should I do it a little by eye...like if someone really heavy was on one side of the car.
EDIT: also what about P/Ns should I just go to Monroe and tell them what I'm doing and they'll tell me what I need.
