From what I've read there are 2 versions of adjustable TCAs around, one with the standard (bigger) ball joint and one with a smaller ball joint that doesn't last long. Where can you get the ones with the bigger ball joints?

And is the rose joint on the subframe mount not too harsh for a road car?

The bigger ball joint uses original ford arms, the aftermarket arms are the smaller ones.

I've got rose jointed arms on my race car and it doesn't feel harsh driving round the paddock, and is great on track.

Are the Compbrakes ones with the bigger ball joints?

Do you notice much difference compared to poly bushes inner mounts?

I guess u mean adjustable tca's one has rose jointed end and is the bollox the other uses original ball joint which doesnt last long and then ur left with a useless part, the rosejointed ones when the roaejoint eventually dies can easily have the rose joint replaced. I have these they feel good and the steering is so much more precise and sharp

Do you mean a rose joint instead of the ball joint at the hub mounting, or a rose joint at the subframe mounting.

I had a look at the burton ones they looked good, hopefully Ade sees this thread as believe he has fitted some to his Sierra and without using a bladed anti roll bar so would be good to hear some feedback

I use the compbrake ones and i assume they are the small ball joint as they only last a season racing
difficult to really notice the difference as my car has adjustable top mounts,compression struts, bladed ARB, coilovers
he means the subframe mounting




My car has adjustable top mounts,compression struts, bladed ARB, coilovers, for the track I was advised to fit an ARB on a road car you might get away with it but you would have to up the spring rate to ccompensate

Must handle good Steve, what bladed arb do you run as most kits I've seen don't allow for fitment?

The Youth.

An MK Motorsport one, nice piece of kit


Combined with the MK 6 degree rear beam the mods found me over 2 seconds a lap at most tracks with the tyres lasting further into the race than ever before, usually my fastest laps were in the first 3 where as after fitment it could be lap 8 or 9

How does the bladed ARB mount to the TCAs or to the compressions struts?


And which coilovers do you use?


I like to take my sapph to the track, but it's still a road car so I want changes to the suspension to also be suitable for the road.

Adam-M

Sounds good the mk beam looks awesome but I couldn't put up with the hassle of waiting like others, so that leaves no options for a bladed arb setup lol

@ marc

I think these are the best option for you
http://www.compbrake.com/product/for...rms-pair-copy/

I've got them on my XR4i and they are pretty neat. They have the original rubbers on the inside at the sub frame.

I don't think they will do alot to adjust the camber on the car as it is only slightly longer than the original one.

i didn't see any diffrene in the balljoints coompared to the original ones.

I was indeed looking at those and the ones with the rose joints instead of the rubbers. But I wonder if the rose joints make the handling/feeling much better, or that they are only making the car harsh and rattle on the streets.


But I do expect you have enough adjustment range for the camber, as that is what they are intended for.

carbon1993

think if you want to get them for the camber you'll be better of with camper plates. They are slightly longer than stock ones Max 1cm orso

wes

How much front camber are you running?

Compbrake sell the large and small ones, large use genuine TCA's as the donor where the small ones use copies as the donor, here is a pic I took years ago now to compare, right is a Compbrake large ball joint adjustable TCA, centre is a genuine 4x4 TCA, right was a Zoo adjustable TCA using a copy TCA as a donor:

As far as I know the adjustable top mounts need the top of the turrets cut off. The top mounts also use ball joints for mounting the strut instead of rubbers, so for the road it won't be any good I believe.

Marc sierra

I don't see any remarks on big or small ball joints on the Compbrake website or on their ebay listings. How can you know which are which then?

Marc sierra

iTrader: (1)

The add from Compbrake actually says they are made from genuine arms:
"Adjustable in-situ, made with genuine arms and original bush". So I guess that should be good then. But I don't see any other TCAs with small ball joints on their website.

Totally fine!

Adam-M

If there fine on yours then ade they'll be fine on mines lol

I wouldn't want to run without the arb. I first had the 28 mm front with the 18 mm rear and that gave me a bit too much understeer. So I changed the rear one to 21 mm, but that was too much oversteer. I now have a 20 mm rear arb and it still oversteered at some point. So ideally I was thinking of the 29 mm front arb from an Escort.


Removing the front arb completely seems a bad idea to me, as 1 mm change is already noticeable. Removing it will upset the balance and I don't want to run harder front springs to compensate.


I was also thinking whether it would be possible to fit a front mounted arb from for instance a bug eye Scorpio, together with a compression strut setup. But then the compression struts would need to have bushes between the TCAs, as with the standard arb, to make it suitable for the road.

Adam-M

Ade use his on track and for drifting, iirc also uses gaz gold coilovers

Marc sierra

Maybe he is running much stiffer springs then, so the removal of the arb doesn't have much influence? Mine is still a road car with AB springs fitted, so it's not very stiff.

Ade

400lb springs all round. Use it for literally everything!
