Right, i have a fiesta as a project car, the aim of it is to be a road-going car that is built for the track

i'm currently looking into alloy top mounts (Concentric or eccentric, i haven't decided yet) but have heared they're not the greatest when using them on the road, why is this?

i'll literally be using the car at weekends, and then occaisionally driving to and from shows and track events.

would they be ok for my car? i'll be doing less than 5k per year

Hello! I have used eccentric topmounts for ten years on my Sierra without any problems. One thing to think about is that you get a set that doesn,t shorten your suspension travel too much, or raise the car. Many top mounts is made of a plain disc that doesn,t allow the upper spring platform to be in the same place as it is standard.

AdamB

thats not too much of an issue... as i'm having my turrets extended

anyone else got experiences of using them on the road?

AdamB

i'm sure there are plenty of knowledgeable people here, i wanna hear your opinions

Hi Adam,

The top mounts will be fine, its the tranferal of road noise when using anything solidly mounted to the shell/chassis that people take a dislike to, you will hear and feel more through the steering wheel and through the car iteself, good in a competetion car, not so good on a full time road car. The shell will suffer a little more stress and you might think about some additional torsion/strengthening to compliment the top mounts, but overall for any track cars i'd say they were beneficial.

cool, well it'll have strut-braces and at least a 6 point cage, i aim to get the engine bay seam welded whilst the engine is out

Where or how are you modifying the existing turrets to take the eccentric top mounts, if you dont mind me asking. Im quite interested in this.

AdamB

if you look at this pic:



you can see that the strut tops have been extended (basically a piece of CDS tubing has been welded in with a flat pate welded to the top)

he has fitted fixed alloy top mounts, but i can go for eccentric if i wish...

raymondo

ah ok, thanks for letting me know. So is it a mk5 your fitting it to? The mk3 ones are already a similar shape but the extension bit would probobaly need to be made bigger. Are you doing the work yourself?

AdamB

mk4

tbh, thats what you'd need to fit it to yours too

Any difference between alloy/eccentric other top-mounts?? what to choose??

I know some of them are adjustable.

AdamB

basically it depends on certain things

if you want to keep a relatively standard suspension geometry, then the fixed version are fine

if you want adjstability, then you will need the eccentric ones
(they allow you to move position of top of strut and therefore adjust suspension geometry)

the only other option is if you want 1 or two piece top mounts

two piece are easier to service/replace bearings, but 1 piece are the norm.

Okay.. and I guess that adjustable not is that much of a must on a roadcar as mine??

Is sound like exiting upgrades when my topmounts need replacement, cause they do make a little noice when driving on paving stone and similar.

AdamB

they will cause more road noise and a harsher ride quality

tbh you'd be best off with new ford top mounts

mines only having this because i'm fed up of having bump steer issues on my coil-overs (down 80-90mm) and also because mine will be a road legal track car so need more adjustability

oki... I understand.. my must be a driveable roadcar

Thanks
