Uprated ARBs.

[Steve Webb]

As far as I can remember the standard front Q4 ARB is 22mm for the widebodied cars and 23mm for the skinny. The Dedra front ARB is 24mm.

I don't want to put an order in for a lot of different sizes, so I suggest that we go for 2 sizes, 26mm and either 28 or 30mm

The standard rear is 19mm if I remember correctly, so what about 24mm and 26mm for the rear.

Thoughts?

I don't remember which was the ARBs size that Jim used to have for his race Q4. Maybe his experience would enlight us.

[Steve Webb]

I'm pretty sure that Jim didn't actually go all the thick with the ARBs . I recall a post where he stated the sizes. I'll take a look for it. He did remove a lot of weight from the car though, which will make a difference.

He also used very hard rear springs. That car did not have an issue with body roll.

The car was also just a track car, so there would be no concessions at all towards comfort.

I should have some more news about the bars this afternoon, so everyone keep your eyes on the thread.

What do you think about 26mm front and 26 rear for track day use? Is too much? (for the rear). Keep in mind that the Q4 at rear is heavier than a standard FWD and I think it require a thicker ARB... Do you think so? I don't want the car understeer like oem setup; I want a "neutral behavior"... Or another solution maybe is to take only rear ARB (maybe 24mm) Sorry, but I don't know what is the better choise.

I'm also interested. I got a 30mm front ARB never fitted but my felling says its to hard. Im building a car mainly for trackdays so some input from Jim Nielsens car would be great.

[Steve Webb]

I'm also intressets, I got a 30mm front ARB for some resan Smith My car but Macbeth 28mm in front and 26mm in the rear is enough. Worldpress be Greta to get input fr.o.m. Jims car.

Whoa, not sure if you outwitted the translator there or posted whilst under the influence.

So you've already got a 30mm front ARB? How well does it work?

But you think that a 28mm front bar and a 26mm rear bar would work better?

And you'd like some input from Jim (Nielsen?) Well I should be seeing Jim sometime in the next couple of weeks so I'll ask him.
