toyokid 27 Report post Posted August 23, 2014 I have been thinking about anti-roll bars as a way of improving handling, now they seem to come in different thicknesses and some are adjustable. Horses for courses, how big is too big? Your thoughts! Thanks in advance. Stephen Share this post Link to post Share on other sites
toyokid 27 Report post Posted August 23, 2014 Is bigger only suited to the track? Do you want more compliance over rough ground e.g. standard? Share this post Link to post Share on other sites
Lauren 2259 Report post Posted August 23, 2014 One of the guys on here, trying to think it was, swopped back to standard sized ARBs, he had the Litchfield kit on but the bar size was verging on silly. If you go too big it will affect traction. I would suggest only a slight increase say 2mm and I'd be tempted to try stiffening the rear first, just for the fun of course.

toyokid 27 Report post Posted August 23, 2014 Kinda thinking over rough ground, you would want a bit of float to maintain contact with the road? Smooth track would be different? Stephen Share this post Link to post Share on other sites
Lauren 2259 Report post Posted August 23, 2014 Well stiffer bars can allow lower spring rates but don't forget the bar acts as a spring. If I was you I'd fit your new suspension first and see how it is before changing ARB's. Share this post Link to post Share on other sites
DaveB 20 Report post Posted August 26, 2014 'Twas me. And yes, listen to Lauren. Back to the stock roll bars. BC coilovers easily enough for the track, I did uprate the bushes to super pro ones. BMW 135i drivers will confirm, now very quick with some good tyres. Share this post Link to post Share on other sites
DaveB 20 Report post Posted August 26, 2014 Also worth considering a front strut tower bar as front struts are fully load baring. Doesn't matter so much at the back because it has double wishbones. Share this post Link to post Share on other sites
