skydragon Posted July 13, 2009 Share Posted July 13, 2009 My seven has an adjustable rear ARB fitted. I've never altered the settings since I've had the car and would be interested in receiving advice on how to adjust and how to use to improve handling etc. The car also has a front ARB fitted (orange I think) I've read that softening the rear ARB will alter the balance of the car and reduce oversteer. What are the trade off's in altering the ARB and which way do you move the link in order to soften/harden the rear ARB? I'm mainly using the car for Hillclimbing and if anything suffer from oversteer on mid/exit of corners (probably due to lack of talent as much as car setup... ) 1.6 K Series EU3, 2003, ex-SuperGrad car.Now Fundraising for the Yorkshire Air Ambulance - can you make a donation?- See my website here Link to comment Share on other sites More sharing options...
myothercarsa2cv Posted July 13, 2009 Share Posted July 13, 2009 Tsk. Take it off. Don't need one of them... Am I right in thinking the orange ARB at the front is the least stiff one? Try disconnecting one of the linkages and see what you think. I find no rear ARB quite nice. Nothing wrong with a bit of roll...

rj Posted July 13, 2009 Share Posted July 13, 2009 It depends very much on the graeral setup of the car. Mine has 20mm rake and is quite understeering if no rear ARB even with the orange front. Link to comment Share on other sites More sharing options...
caterhamnut Posted July 13, 2009 Share Posted July 13, 2009 To answer your question, here is a rough piccie - angles etc just for illustration, but you get the idea: here If you think of the arms as levers twisting the anti-roll bar (which they are!) then it actually makes sense - the longer the 'lever' (the bit with the holes in) the easier it is for the car to twist the ARB, and therefore roll - the shorter the lever, harder it is to twist the bar, and therefore car rolls less...thicker ARB harder to twist, etc etc As has been said, then depends on everything else, set-up, how you drive, where you drive etc etc For example, if you happen to have quite a stiff front end with very little droop, and no rear ARB, this here can happen Angus's Blatchat Blog Edited by - angus&tessa on 13 Jul 2009 13:11:33 Link to comment Share on other sites More sharing options...

skydragon Posted July 14, 2009 Author Share Posted July 14, 2009 Thanks for the explanations, the basic adjustment now makes sense. I think I will try making the rear ARB one hole softer and see what happens. For Hillclimbing (tight bends, frequent camber changes, etc) what is the general consensus of opinion on the best mix of front and rear ARBs?

Englishmaninwales Posted July 14, 2009 Share Posted July 14, 2009 As RJ states, it's really down to the set up of the rest of the car; spring rates, rake, tyres, front ARB, camber etc and finally personal preference. In theory, softening the rear will reduce oversteer. malcolm Link to comment Share on other sites More sharing options...
