I have to say i think ARB are a quick tuning tool.
If you getting a lot of bite and chassis roll they do lose some grip and help mid corner rotation. I think on loose or bumby surface you want full free travel. |

Agreed Neil, I always have them with me but rarely find the need for them as the FS is so beautifully balanced nautrally.

I agree with this on corning entry.. it helps the car go into the corner much more easily, but still sure footed and planted just easier... but through the corner, yes it doesnt roll as much.. but the extra drive and the feeling of the car well and truely planted was a huge difference and to just change this at Chadderton on sunday and go 1sec a lap quicker that should surely tell you whay im trying to explain.. Mattb will tell you i was very reluctant to try the roll bars after not liking them at all outside... but on the the type of indoor smooth surfaces, carpet or worksop type floor i know what i'll be using... im so glad i tried.. With out the bar you can still hug the corners but jump on the power to quick and the back wants to kick out so you have to be smooth on the power delivery... with the bar.. bang and off you go! I reckon if it wasnt for speedo issues i would have been in the A looking at my laptimes in rd4 and my B final.. The top people in the A were on quick 19sec laps.. i was in the same 19 sec a lap bracket but not as quick... usually im 1 sec a lap down on the top guys.. So glad Matt kept on at me to try the bar... cheers dude! Cheers Nick ![]() |

Lap with you in front! I made a couple of changes to the Durango after a bit of help from Criag Collinson and it felt much better in the final so Its staying for now!(cheers Craig!) |

When i first tried a bar on Sunday it was the 1mm.. and even that made a difference... i went to the 1.2 and it was even better.. Remember the dusty coventry track for the Mid West regional this year.. well the car was doing exactly what it did at cov on sunday on the corners.. the roll bar sorted it.. so i reckon 1mm for out doors will work on instances like that for sure.. matt has always run them especially on the " looser " tracks" bumpy tracks like cov astro, loads of grip and no kicking out issues.. there no need for one.. ![]() |

Did a bit of dremel work to give a bit more steering lock and changed the wheelbase a little, oh and swapped my 6.5 for a 5.0 turn, much better!

I have been asked to say something about the anti roll bar issue. I have been helping out Matt B with his car as he is a very good friend of mine. He loves the car but he just wanted alittle more from it, so he asked for my help. You all know I have driven the car so I do know a little about it. It does under steer on the fast sweepers and the back end is unstable over ripply sections.
It is a very strong car and very reliable car. Back to the anti roll bar. A 4wd car should turn up its own arse when turning with the power on. With the pin out of the slipper this will not do it. It understeers as all the power is going to the front wheels and not the rear. Put the pin in and it will turn on power. Even with the pin in the rear end in THAT planted it will not come round when you waant it to. We have tried all different camber link possitions and alsorts of toe in possitions. Put an anti roll bar on and it will come round. All that this does is take grip off the rear. The thicker the bar the more grip it takes off. It will not effect it over the bumps. If you dont run an anti roll bar then you like a car to understeer. Yes this is the safest way but it is not the fastest. If you watch a Durango, thats what you want it to do but you tone it down to what you like. I bet now, go and see Ellis's car and it will have one on. |

stus right it does not affect the car over the bumps with a roll bar on to get the rear planted over the bumps you just need to get the anti squat and the damping right.

That depends on the bumps.
If they are hitting one wheel only it tends to unsettle the car. Bear in mind the Anti roll bar is just that, it keeps the car level under load in the turn. Correct damping can compensate this but on a track with differnt cornering forces and jump requirements getting the overall balance is the trick. BTW i nearly always run ARB. But then i always race on high consistent grip without too many bumps. Lately i have ben running front only and it seems real safe in the corners. |

my preference at stotfold is to run both roll bars like it says in the fs2 kit with silver springs on the front and blue on the rear, its so safe to drive and it seems to land so well with the small size shocks.
as for shocks on the rear, it has loads of traction as standard and you dont want to lose steering, if anything it needs less ackermann imo |

Ellis sets his cars up to run without roll bars, they make cars very unpredictable.

i feel anti roll bars are a great tuning aid but a lot of it is personel prefrence in my view ive run the car with and without and for me the car feels a little vague and looses traction which we know but what i do feel with them especialy my car is the car has the same charistics as my touring cars had when i tried them. like i said its personel preference for me its a no dont run them but i will tend to alter the roll centers shock oils etc anti squat etc before going down roll bar route.
car is pretty good. stu rand |

The whole roll bar thing will be a personal preference for sure..
I'll report back after worksop this weekend and give you my verdict.. but im certain on the type of worksop surface similar to chadderton it will be where im at with regards set up... Ive posted arNo my setups which he has put up on petit rc in the kyosho section under the setups tab if anyone is interested.. Nick ![]() |
