Front ARB - fixed or adjustable

[KenEvans]

I need to soften the front end roll of my Superlight R a fraction to change the slow speed turn-in from good to absolutely perfect. It just understeers a bit on entry, and I know I'm not trying to go in too fast.

 

I've currently got a 19mm yellow and am considering going to a 16mm red, I think it's that subtle a tweek required.

 

I've considered an adjustable arb but I wouldn't know what angle the blade would need to be set at to replicate the 19mm roll stiffness so that I could back it off a tad and I don't have enough time to experiment before my first very important hillclimb.

 

Any comments?

 

Thanks

Ken, for what it's worth I would go with the fixed 16mm Bar to try at Loton, keep the 19mm with you, it only takes 20mins to change if you don't like it. I think you could spend the best part of the day trying to set up an adjustable bar, and whilst I want to beat you, I'd hate to do it just because you've upset the balance of the car.

Hello Dave! We rarely see you on here :) Sounds good advice to me coming from a Gould GR61X techie

I spoke with Freestyle about this very thing recently as I am thinking of buying an adjustable ARB. Gary May advised me that the fully stiff setting = red arb and the fully soft is very slightly stiffer than the orange arb.

Hi Malcolm

 

Thank you for that interesting bit of information. I may well go Freestyle in coming weeks as a result
