Hi there, I just had the front springs replaced on my 1990 GT convertible but the ride is still awful (every tiny bump in the road feels horrendous!). I am pretty sure the shocks are still the originals - any thoughts on any kits that include bushes, shocks etc, etc that might make a difference? Just really want to make it a bit more user friendly. As always thank you in advance for any suggestions folks

If you are keeping it pretty much stock then just get some KYB Excel-G gas struts and shocks or the like. You should also look at the bushings on the front lower control arms as well as bushings in the upper and lower rear control arms. Typically if the bushings are bad in the rear upper control arms we just replace the control arms and then get the bushings that install into the rear end. On the rear lower control arms you can replace the bushings albeit they are a pain the butt. Some just replace the lowers with a quality aftermarket unit like Maximum Motorsports, CHE, J&M, etc. I would just strongly suggest that you do not get urethane bushings in both ends of the control arms as they tend to bing the stock style suspension.
Other things you may consider are replacing the front sway bar frame bushings and end links, replacing the rear quad shocks, and if necessary installing some caster / camber plates. CC plates woudl only be necessary if the alignment tech cannot get the front-end alignment into spec. Best ones on the market here:

Maybe someone lowered the car with the old heat the springs up with a torch method.

Any thoughts as to a sensible set of replacements from the likes of CJ Pony Parts (they ship to the UK)? Thanks

Monroe OESpectrum shocks and struts may give you a close to original quality ride, depending on your springs.
Junk/deteriorated bushings could also contribute to ride quality, after the shocks/struts.
Thanks, any thoughts on whether best to replace with rubber or plastic bushings?
My experience is to use rubber bushings in areas where you get a " twisting" action, like control arms... Poly is fine elsewhere..... Squeaking was the problem I experienced when using poly on control arms or the shackles on a leaf spring......
Yes. If you drive the car much you need to keep them greased up. I went with spherical bushings but my car is not a family cruiser and I am willing to sacrifice a little bit of ride quality for the grip and handling.
Thank you for all the comments - new shocks have helped.
I have another question....the anti roll bar on my convertible is enormous (ie very thick/big diameter). The guy helping me fix it up thinks a smaller one might help with the very firm ride....any thoughts (obviously Ford put it on for a reason on a convertible but it seems overkill)?

You can try a 4 cylinder one but the handling goes to complete crap. Have you replaced the control arm bushings? IF they are the factory ones then they are over 30 years old and will be in need.
What size tires are on the car?
You may think is sounds weird but when I put subframe connectors (weld in) on my cars the ride got better.

Sounds like the control arm bushings are needing a change. I don't think any previous owner has done that looking at the history - I will go with OEM option unless you suggest otherwise.
Tyres are very new (less than 200 miles) and are 235/60 R15 Galaxy Radials
Are those subframe connectors bespoke or off the shelf?
