Front anti roll bar
Discussion
Bars are made in narrow track width and wide track, varying thicknesses, the rubber bushes are colour coded... main ones are;
1/2” Orange
5/8” Blue
11/16”? Red
3/4” Green
Which bar is best depends on whether you have a rear ARB fitted and how it’s adjusted, overall setup, LSD or no, wet or dry etc etc
Infinitely adjustable front ARBs were never supplied by Caterham and tend to be prohibited by racing regs- which is probably a good thing because the incremented bars are choice enough. Racers might carry two or three, and may dispense with ARBs altogether, usually if the session looks to be wet throughout.

P.S. Rake has a big impact on the way the car behaves in roll, check and adjust this before experimenting with bars if you haven’t already. I have spent half a season trying to compensate for excessive oversteer with bars before realising that the 15mm of rake I had on the car was way too high

ISTR 15mm is pretty much a standard rake - I ran mine with that and it was fine. Did you try disconnecting the RARB? I appreciate there are lots of other variables ForzaGilles said:

I appreciate there are lots of other variables The car worked a lot more nicely when I reduced it to 10mm. Once I did that I found that I was messing around with bars much less. There were some people who were quick with no rake at all in the same spec car (Sigma 140 / LSD / Widetrack / 6" list 1Bs). I wish I'd experimented more, alas only had the car for one season.
No racing god, but the at what fuel level did you measure the rake? Mine gets decidedly more lively towards the end of the tank, I'm lead to believe that's normal and due to the rake increasing as the fuel comes off.
Adjustment wise I've settled on a red bar (narrow), which leaves me somewhere near the middle of the adjustable rear. That's just trackdays mind.

No racing god neither hence I never once noticed that, I was only doing sessions of little more than 20 mins so the fuel difference over the session would've been something like 8kg.

I would've corner weighted it on the series minimum weight which for me was ~90kg in the drivers' seat and 10l of fuel or so.
Should've really done the lead ballast on the passengers' floor.
Red bar was the most popular but I liked my blue. Never found a purpose for the orange one. Rear was on one of the two softest notches or disconnected altogether.

Simon do you have a web site or details somewhere?
I might get bespoke wishbones made too... But would be interested to see a blade set up for std (wide track) wishbones
