So as many of you know since August last year, my car has had a rather obnoxious clunk, it's not got better or worse.
However, I've got pedders xa coilovers (http://www.pedders.co.uk/extreme-xa-coilover-kit_p31627189.htm#.WuuGIIiUu70) and the steeda irs base pack (https://www.steeda.co.uk/steeda-s550-mustang-irs-base-pack-c2x22649870) bushing inserts on the car (and later down the line steeda topmounts - https://www.steeda.co.uk/steeda-s550-mustang-billet-rear-shock-mount-c2x25672762. It's driven with both of these on fine for a few months however then began to devlop a clunk (IRS and Pedders), it's only ever occurring on uneven roads.
I've been to multiple suspension specialists and messaged many people on here individually about this clunk.
The car has been back to pedders to have the coilovers looked at, and it was determined this wasn't the cause.
It's been with ford twice including their master tech, who has also determined that he cannot find it.
I've been told by Ford to bring the car back standard and see if the clunk continues. I've personally removed and refitted it to stock on my garage floor - the clunk was still there
I've had tegiwa imports also look at the car, and they couldn't find anything.
The cars had all of its bolts retorqued to spec numerous times and the most anyone can ever muster is "the exhaust catches on the valance".
I'd been suggested by people here that it may be the topmounts so these were switched out for steeda topmounts, and the clunk continued.
I've driven with the mufflers off the car, and guess what. It still clunked.
The ford tech, however, this week told me that it could potentially be the steeda inserts (the metal ones), and asked me to test with these, out, i'm reluctant to do so because they're a bit of a **** to fit, but also because it drove for months on these without clunking.
He's also suggested maybe needing different IRS bolts as the car is lowered, and therefore less thread to grab (?)
Ford have confirmed all bushings, NVH deflectors, and other bits and bobs under the car are in full working and serviceable condition with no noticable issues.
Ford also confirmed both brakes and hubs are fine.
I do run aftermarket alloys which have a CB of 72.6 (vs the cars 70.3) the 'hubcentric spiggot rings' i had were plastic, and have died. They've been off the car for a long time. I doubt this is the case... But i can get some to test [MENTION=21881]MustangMustHaves[/MENTION] ?)
I'm at a wit's end with what to do next, the clunks got to a point where it's generally all I hear when I'm driving on uneven roads and it's begun to grind itself on my sanity lol.
I've been considering seeing if a BMR CB005 will remove the clunk in its entirety; however, I don't want to pay for something that may end up making the clunk worse... or not improve it (that said, if it did, I would).
Beer for whoever fixes it/finds out what's wrong
