Noise at revs

[1hpclio]

Hello, im stuck with my clio, got a noise when flooring hard, sound like a grinding noise but not constant, comes and goes very fast, sounded like a wheel arch, checked susnpension all ok, it has new ktec coil overs, 4 new tyres, new driveshafts, alloys balanced, brakes are new, gearbox mount seems ok....started happening after i put amax springs, then oem shocker died and front end was really low.... Wanna burn the car now, really annoyed me with the amount of money iv spent on it... Thanks in advance to anyone

At high revs? Could well be the exhaust mani hitting the subframe.

Try loosening the upper engine mount, pulling the engine towards you and tightening the bolts.

If that doesn't work, then it's new dogbone mount time (assuming it's the mani hitting the subframe).

If it helps anyone, was upper gearbox mount that was shot, replaced all ok now
