Vibrations!
sorry guys this is not about the old polish club
Has anyone changed the dogbone engine mount by replacing the original soft rubbers to a much harder compound? and then found that there is a slight vibration at idle???changed the clutch yesterday and while I was under the car I changed the dogbone mounts.The clutch and all assoc stuff was replaced correctly.

Who recommended a clutch replacement without doing the flywheel ? Did you at least replace the clutch slave cylinder ?
We had a flywheel blow out a while back in one of the race cars , the two parts of the dual mass seperated and damaged the whole housing of the gearbox and also the input shaft of the gearbox . We always replaced the flywheels from that point on .
I always replace the dual mass with the steel one piece flywheels . They may rattle a bit more at idle but its a lot better than paying the $1200 or whatever it is for a new flywheel .
The other thing Im curious of is your claim of 176kw out of a DBC car with a KO3s . I claim 180KW with 3 inch exhaust and the smaller KO4 kit . All the KO3s is is a KO3 with a larger exhaust wheel

I bought a dog bone kit from ECS tuning and that vibrates quite a bit at idle. I reckon you could get away with only changing the biggest bush and that wouldn't introduce as much vibration.
I also just did the wishbone bushes and the ones that I removed were shot to death. The car steers much more positively and doesn't wander off line round bends any more when you hit a bump.

thanks guys for all your responses!! I just came back from Nelsons bay,500km trip and it seems the rattle has died down.definately the dog bone.
oh,I forgot.The chip that I have put is the mtm 176kw chip which im sure you know about.I have not used their turbo or injectors just their chip that is claimed 176kw.As I have dyno'ed the car before chip,I will be shortly dyno'ing again with the chip.The person doing the dyno is a third party who is not involved with any chip manufacturer/seller.
and as for changing the flywheel,why would it be necessary to change it when there is nothing wrong with it?my car is not a race car,just a fast daily driver.

What else have you done to the car ? A KO3s wont flow enough get 176kw . 176kw from a drive by cable car means your going to need around 130-140 kw ATW's .
As for changing the flywheel , they are a servicable unit . Last time I checked a clutch kit for a gti from a dealer included the flywheel . Same reason why a thrust bearing and pressure plate are changed , they wear out ! .
And your car might not be a race car , we changed the clutches on those cars every 500 or so km , so the '000's of km you do would equate to the '00's a race car does . There has probably only been a couple of dual mass flywheels I would have re-used that still had a small amount of play in them . But its your car so its your choice
