Adjustable tca's are they worth fitting on fast road saphs ?

prob just that they give a harsher ride
if you like a nice smooth drive then any motorsport part
i.e poly bush/rose joint etc will be a harder drive
but increase the handling ability
so its more to do with what you want from the car
unless you do drive the car hard or on track regularly
then they prob aren't realy required,
but if you do then yes they can make a decent bit of a differance

I guess you'd fit adjustable TCAs if you want to alter the camber at the front. Do you? Are you looking for more negative camber? Maybe think about adjustable top mounts also?

As above m8.
Short of shimming the TCA arm/ARB junction there isn't an easy way to increase caster on a standardish Cosworth front set-up is there? I've noticed a few recent articles ( esp on the 3-door rwd ) commenting how they don't have much self-centreing action compared to modern sporty cars. The caster also helps preserve the -ve camber on the wheel as you turn it which helps keep the outside wheel flatter to the floor as you roll onto it in a corner
Put it this way, fast road or not fast road, does anyone consider the constaint of the standard TCA adequate?
I think its a shite design to start with.
Fitting comp struts does not create a harsh ride. It is the way that people don't run a roll bar with them and then have to run stupidly hard spring rates to stop excess roll that creates a hard ride.

if you run a front mounted arb to compensate for the comp struts yo won't need the stiffer springs, but the tca's being adjustable makes it better rather than worse
Personally I would have thought it would be barely noticeable being as most Cosworth owners seem to have poly-bushed TCAs/ARB mountings already and are often running 17" tyre combos?
Someone once told me that polybushing on the front end just adds precision without too much extra NVH......it's usually once you start on the back of the car ( solid beam mounts, solid rear arm bushings etc ) that you start to really introduce NVH into the car and interior.....
I suppose the advantage with having the strut tops cut and adjustable top mounts fitted is that if you choose carefully you can get caster adjustment ones as well.

The bearing in the centre of both types still only rotates around the same amount of degrees dan boy - so no matter wether you have multi adjustable ones or fixed eccentric adjustable ones the bearing in the middle does the work. If your going greater than 10 degrees then spin it round to its next setting where it will need to be anyway !!
The main difference is just what angle the bearing sits at and if it is within its movable tolerance the result will be the same or similar.
The options then come down to if you wish to modify your strut tops or not or if you think your actually getting something better (bling wise) or if you think you can actually tell the difference on a road car between 2 10 degree offset holes. Be a safe bet to say you can't.

because you are removing all bushings between the tca and the floor of the car, so all road noise is transmitted directly to the floor pan.
the first time i drove mine on comp struts i thought i had broken something, seriously!, every single bump in the road, ends up as a bang on the floor. i never changed any spring rates, or any other settings, they make a horrible road car imo, and i know a lot of people dont run them for this very reason
but the tcas made no difference at all to ride quality imo

i've done it, but to be honest, it wasn't used as an everyday car and i probably only did about 100 miles in it years ago so not really a fair comparrison to someone who would use it everyday

Dan - if you want to adjust caster and/or camber do it at the bottom of the wheel where it is most effective. Do not expect to adjust the settings using only a top mount. That should be there to keep the settings not adjust them !!
Running extra negative will theoretically pull the wheel in at the top away from the arch, not towards it.

At least you will be able to set the camber to the same both sides......even if you don't want to add extra. It's always interesting to look at your current settings and see how much they vary from side to side.....there's quite a lot of "tolerance" on many older cars
