Default Knocking noise upon accelerating

HEy guys

I was driving back from the airport having droped my mate home and noticed a very very sutle knock when i step on the accelrator. You can actaully barely hear it but i feel like it got slightly louder towards my trip back.

Going through the gears normally every time i step on the accelerator thers a sutle knock from the front. Now the gearbox/clutch is mechanicaly sound and i havnet changed the box or clutch recently (only owned this for 2 months).

Car drives fine and nothing is wrong at all, full locking the wheel there is no noise. I'm guessing engine or gearbox mounts, wheel hubs possibilty? Its very very very sutle at this stage but almost sounds as if something is loose. IT doesn't always make the noise, i mean i have to give it a full foot real quick to hear it.

Car : 2002 CLUB spec 5
MODS. DBA slotted rotors, lowered king springs, TBE
EDIT: ENGINE IS STI EJ207 with a TD04 and not even verso'd tuned. 60 000 ks. Chassis done 187 000ks

NOT continious engine knock, when i jerk the accelerator once i hear ONE knock and thats it. Happens when thers alot of weight transfer, like something is loose

So any insight would be great, not too fussed because its going to Stechnic this tuesday though.

Cheers

Adrian

Got much clearance from your dump pipe around the steering knuckle?

I'm just guessing, but maybe could just be worn bushings?

Engine revs perfectly fine, it sounds more like suspension.

NOTE: engine IS a STI EJ207 with a TD04 and not even tuned. Its basicaly stock now driven 60 000ks by maximum motorsports. I also drive my car like a nana so i doubt its engine. Its going into Stechnic, the noise is very stutle and engine revs and drives normally. The knocking isn't engine knocking by the way.

NO excessive oil or water usage, everything is as fine. It just knocks once as i jerk the accelerator, its not a continuous knock knock knock... which leaves me to believe its engine mounts\gearbox mounts of some sort. Worn bushings also a possibility. If i gently apply throttle and made sure the car doesn't have weight transfer there is no knock

Actually just took it for a drive, can't even describe this noise as a knock, its so subtle and defiantly sounds like something is lose. Looks like i'll just leave the car with Stechnic on tuesday and they can sort it all out

Luckily its not my daily
