It helped to reduce understeer. When I fitted my ARB I headed off to Spa Francorchamps in Belgium on a trackday; I was impressed with the overall handling of the car and reduced understeer.What difference did fitting the rear ARB make to the handling? I take it it is the Whiteline item, is it set to 'drift' or 'grip' and what is your opinion of it both on track and the road? My car is setup for road use and so I don't want it to be too stiff. I certainly noticed the additional stiffness of the car from fitting polybushes!
However, back on UK roads there was more front end grip when using roundabouts; overall a good handling addition.
That's what I need! So I should be looking at convincing the wife that we need an adjustable rear ARB next? Or should I be going for complete polybushing first? (I'd want to replace the ARB bushes with poly bushes at when installing it anyway.)
This is the thread to what Jim was talking about. Click meThe key could be as simple as the adjustable pillow with uprated struts - I remeber Jim (Campbellju) telling me that this was an incredibly cheap and simple fix for the handling on an R, but I couldn't do it because I don't have adjustable mounts. Andy might remember what he said because he was there at the time (NW meet).
Personally I’d go for the rear ARB, it’s cheaper than going for a complete polybush set and it’s quicker to install (less time off the road). ;-)PobodY said:That's what I need!

www.adrenaline-race.com will make you a set.Radleigh- chassis bars sound a good idea but I don't know of any companies that make them for the R. Have you seen any advertised? It is very interesting what yo say about not having an ARB and the affect this has had on reducing understeer. What is the reasoning for removing it?
I also raced a Pulsar with GAB suspension units and they were C**p. Spring rates and damper rates were miles out.
Rollbars are there for a reason so I would not remove them. The car might well oversteer more without them but overall you will have less grip as abviously the car will roll more is common sence really, so just sort our better ones. (Whiteline rear to start) one thing you must do is poly bush everything.
The 2 most noticable improvments (as I did most of my suspension mods all in one go) were the lower 4 location strut brace, but the biggest imrovment to stiffen up the car was undoubtably the full rollcage.
I'm no expert - I'm just listening to what people say, taking a look at some references, and drawing some conclusions.PobodY- so what you are saying is that having after-market suspension which is undoubtedly different to OE settings will have a knock-on effect with the rest of the chassis setup, therefore the front ARB is less effective at doing its job. This I understand. So would leaving the front ARB as it is and only fitting an uprated rear ARB still compromise the handling? I suppose this is why Whiteline have engineered front ARBs too. What size is the standard front ARB? Whiteline make 20mm and 27mm versions. I can't understand why they would make a larger front ARB because surely that would only increase understeer because it allows less roll...
