Default Are anti roll bars needed on a track car if using compression struts?

I've hear different opinions as to whether anti roll bars make that much differance on a track car,

the dilemma is on the fiesta 4x4 cosworth I need to decide whether to add the expense of group a anti roll bars front and rear?

Bearing in mind the anti roll bar set ups cost £525 each!

I've asked Andrews opinion an he says that as I'm running fully adjustable front end with compression struts and a 4 link wrc style rear end with comp struts that for the extra expense and hassle it isn't really going to be that much better!

Opinions please as I need to decide now really while the chassis work is being done, also I have maxed myself out currently spending wise but if I have to I will find the money to get them added now while it's at that stage,

thanks Marc

think it was with road/track cars that peeps prefer the anti roll bar set up, saves having big poundage springs on a road car then, on a track car,it does not matter.

wait for used kit to go up on ebay, they usually go for around £250 for a complete front or rear kit

can you get Andy to loan you a kit to get the mounts fabricated, and then you fit your kit when you find one, if you find it necessary ?

That was the plan but andy doesn't have any spare roll bars laying about and the grp a front and rears are different so I'd need one of each,

the front I will try and do as it won't be so bad to mount the brackets but the rear will be harder as I have a complete sheet
metal rear end/floor so will need more tubing braces to attatch mounts too!

Anybody lend me a grp a front and rear roll bar set up just so I can get the mounts for them positioned?

get the mounts fab'd up and fit them later

i know that you can't get a spare set of arb's to use, but surely you can figure out the mounting points using a bit of maths and stuff?

or isn't it that simples?

IMHO every trakday car should (budget permitting which is why mine doesnt currently) have bladed anti rollbars front and rear, its the easiest possible way to alter the roll resistance of the car to suit the track you are on, and that way you can run with less aggressive poundage springs so if you are on a bumpy track you stand a chance of still getting it round it.

Even more important when its a road car too.

Anti roll bars are an intrinsic part of the cars suspension ,whether you as a driver will ever notice the difference in settings is another matter tho .
In my opinion you would be better off buying them now while you can .
I would like to see the quality of the ATM items as well ,we only supply the original ford versions and our chassis brackets so cant compare.

As per Chip, ARB's are good to use with Comp Struts to 'fine tune' for different circuit conditions.

Makes no difference if its a compression strut vehicle or not, the same still applies IMHO

this might sound daft,
can andy not make one? or can you not use something else? like an uprated std fit cossie one?
i know you wanna use the best parts available but £1k on anti roll bars might be a bit over the top, especially if andy says you dont need one.

Stu, he isnt talking about strut braces, he is talking about anti roll bars.

Cornering forces near harrogate will custom make adjustable bladed antiroll bars to order, including the bracketry if required, thats where I would be going with it if its something andrew doesnt want to take on.

Totally agree on bladed ARB for track cars with our without comp struts. Cant see how you can get the best out of your car if you dont, unless you have a pit crew and a huge set of springs to choose from

Even if you do, you will lose grip on turn in if you rely entirely on springs for roll resistance.

Ok well it looks like its best to go with them and now is the time while Andrew & Scott are still doing the chassis and suspension work etc,

I have emailed DEWITTS for a price on the complete kits front and rear to compare to TCS's and ATM's and in the meantime i have pm'd a few people to see if borrowing a kit to dummy up is possible so i dont have to buy the kits just yet,

if anybody knows of any for sale for sensible money please let me know

Make sure whatever setup you get is a bladed adjustable setup, pointless spending the money to fit them and not do it correctly, you'll only end up spending a fortune redoing it at a later date.

i will be using the proper grp a cosworth bladed anti roll bars chip,

the most annoying thing is that there is no where to mount the brackets to at the back of the car so will have to add extra tubes or similar to make somewhere which just adds more weight but im not chasing 10th's of seconds so think the handling will compensate for the weight added

Is there that much different over a bladed adjustable setup and a normal adjustable setup (IE whiteline)?

Ultimately its more configurable, but yes ANY adjustable setup is infinitely better than a non adjustable setup.

You could try www.xworkss.com
He has some of what I had made, exact replicas of what Ford supplied, tarmac specification, with the correct material and double taper left and right handed blades etc.
Made for an RS200 but I am told are the same as the GPA 3 door.
Gus may of seen them, as I think it was his car that has been there.

They are not cheap though.

No never !! (front or rear)

Thats why it does not understeer at the front or oversteer from the back !

If you are finding that you are getting understeer or oversteer with the ARB's connected, try dropping your spring rates a little, rather than disconnecting the ARB, it should also cure that problem.

Yeah I remember having a chat with you about it many years ago and my mate had a quick go in it and was blown away.

No problems with the turn in then with no arb
