Suspension Upgrade Questions
Ok I dont know a lot about suspension but Im pretty sure my cars suspension is getting worn. I know I have the yellow adjustable Konis and I want to upgrade my suspension by rebuilding them and probly converting them (all 4) to coilovers with the height adjustable ones from paragon. Now my question is what parts do I need to get because there are so many options on their site. I would also like to hear some of your recommendations. This car is going to be a daily driver so I dont need anything too stiff. Here are some pics of what I currently have.

talk to skip or jason at paragon - they are both extremely helpful.
for my setup, i have their adjustable ride height kit in the front with yellow konis and 275 lb hypercoil springs. this is really not that stiff - even on the street. the rear has the KLA industries coilover helper shock with 140 lb springs. i would like it to be even stiffer. you can do the front strut conversion yourself, or pay the extra $50 per side for skip to do it.
if you are looking at competition at all, or just want more adjustability in your ride height, i would definitely use their setup. you have to replace the internal strut cartridge, plus sleeve the strut housing with the threaded collar and spring perch. for your purchase, you need the adjustable ride height kit and then pick the springs you want. i would also recommend changing the upper strut bearing while you're there. make sure you get a good alignment after everything is done

First, lift up the boot on that front strut to see if it's a Koni conversion to 8641-1414S (an insert, should have a black rubber cap) or the standard sealed strut (will have a non-removeable crimped on cap). Our adjustable ride height kit requires that you have converted struts (so the threaded sleeve will fit). [NOTE: On many 86 951 OE applications, the top seled portion can be shaved slightly to make the sleeves fit.] If you cannot use the ride height kit with your struts, and you want to keep your struts as is, you can get lowering from a set of Weltmeister springs.
There is no conversion for the rear shocks to coil over but there are several other options. Any change either to the torsion bars themselves or to make allowances to install a coil over will require you "do" the torsion bars.
Just off the hip from what you already posted, I would think you'd be happy with 300# front springs and 28mm/29mm rear torsion bars or 200# rear spring if keeping the t-bars OE and going with a coil over.
If you want to avoid doing torsion bars, then 200# - 250# for the front and consider upgrading the rear sway bar to the 19mm 968 M030 type (especially for 250# fronts)
Aside from the apparent need for new bump rubbers (ride height kit comes with Koni comp snubbers), check for play in the ball joints, tie rods, upper strut bushings, sway bars bushings, etc.
Good Luck!

I recently purchased the Koni yellows all around, did the strut conversion myself, switched to camber plates (because my strut mounts were worn) and installed the ride height adjustable coilover kit. My car feels 10 years newer eventhough it felt good before. I purchased all of my stuff from Paragon and they were very helpful when I got stuck during the installation. Surprisingly the strut conversion (hacksawing and drilling) was the easiest part. Compressing the springs and getting the strut package in place was the biggest pain.

Here's a question for you guys. I got some lowering springs, and they seem pretty short. Stock 951 spring I pulled out was a 15 1/4" spring. New ones are 11 1/4". When I re-assemblel the strut, the spring has about 2" of play up and down before contacting the perch. Does this seem right to you guys?

I am considering taking the ride height adjustable part off of my strut to lower the car maybe another 1/2 inch.

Geo, it all depends on the rate of the spring. A 200# spring may be 12" while a 400# spring may be 8". The lower rate spring still do sometimes need to be compressed to install, especially with the flat style camber plates.
Poindex, I'm confused on the last statement - did you chop off the lower perch before installing the ride height kit? If not, you should. You'll gain another ~1" of lowering by doing that.

Skip,
Thanks for that info. I did not cut off the lower perch. From looking at the strut I didn't think I'd get much benefit from doing that.
What options do I have for cutting off the perch? I know a spinning wheel grinder (or whatever its called) would do it but I don't want to buy one. Is there anotjher more useful tool I could purchase to do the job?
I guess I could rent a grinder.
Thanks,
Mickey
