Suspension help please

Had the ccabby lowered just over a week ago, with Coilovers. Apparently they are as high as they go but the floorpan is knocking on the suspension arm.
Every day now, I have left it with the garage during the day to look at and try to resolve. First they said it was the exhaust knocking and spent 3 days sorting that.
Yesterday they said its the floorpan hitting the suspension arm as the arm itself has been pulled up to a 45 degree angle due to the coilovers. They are running out of ideas and suggest I put the old suspension back on, so I m turning to you guys to see if anyone else has had the same problem?

Where is this garage? just so i can note not to go there

They trying to say the wishbone? is hitting the body? Its probably the driveshaft, but then that shouldnt really be hitting if they are wound all the way to the top

Its Portley garage in Littleport, they dont like problem solving, just basic servicing, mots and replacing parts the computer says needs replacing, but its convenient cos they are right behind my site.

It turns out the mechanic was exaggerating about the suspension arms, he just doesnt like lowered cars.

I had a butchers while it was on the ramp and it was the anti roll bar that was hitting the floorpan. It seems that the only option is to remove it completely and I will try it again tomorrow.

AAARRRRGGHHHHH!

Anti roll bar removed, you could see where that was hitting the floorpan but it didnt fix it.

I look at the suspension arm and it looks like that could be hitting it, there is only millimeteres between them, but the garage think not. They reckon its the driveshaft knocking, but I really dont think they are hearing the same as me. I hear several knocks under my footwell in quick succession as I release the accelerator (while moving only, not at stansd still). My limited mechanical knowledge disagreees with the driveshaft theory.

They want to try to raise the suspension a bit but also tell me its as high as it can go. I dont want it higher, if anything, one day I might want it lower.

driveshfts do knock when the pedal is lifted, if they are getting knackered.

you sure all your ball joints, top mounts etc are all in good condition, tight and put together properly. top mounts, bearings, washers, nuts can look confusing when in bits and knock like f**k when wrong

It has now been raised an inch and no knocking whatsoever. Still not happy though, a waste of money.

So they was talking s**t when they said it was a s high as it would go then?

Get some pics up, might be able to help more. My cabby was pretty low and that used to bang the driveshafts alot, but i dont think anythin else hit

They must have been talking shite. I remember your cabby was pretty low, was the noise you had similar to how I described?

I dont know anything about ball joints and top mounts. I have to trust whoever is working on it at the time.

Not really, it was more on bumpy roads etc which made the shaft hit the chassis leg.

Did you fit new topmounts when fitting the coilovers? To me from how you describe it clunks when you let off it sounds more like an engine gearbox mount gone? or topmounts if they are old.

Tbh id recomend taking it somewhere else
