The less roll and greater grip with a front ARB will exacerbate the oversteer issue, because you'll be entering faster.

However, your ears will sense the increased (relative) rear roll, which makes the breakaway easier to judge.

This is why Honda softened the rear ARB with the first lot of suspension tweaks.

I'd personally sort out the tyre issue first, in order to optimise the basic car, before buggering about with its fundamental settings.

I tend to feel that in order to retain the balance, you should thereafter do both ARBs.

Sod the cash!

I know what you mean. But I was going to do both ARBs anyway, so I might as well compensate with something I was going to do anyway. IYKWIM.
Personally I would be wary of swopping to a stiffer rear ARB without adjustable dampers as on 17" wheels I found the increased harshness noticable. I can dial it out, but you won't have that luxury. Also bear in mind that the Tanabe ARBs are an even bigger step upwards in stiffness from your OEM ARBs as compared to MY02 ARBs.

It's worth pointing out I'm not too bothered about the oversteer. But what I don't want to do is stick one ARB on and have even MORE oversteer.

Expensive week:

realistically I need

You've given up on only having the one set of wheels/tyres then?

I'm worried that the noise which I thought was from the front is actually the diff. And if I'm making a warranty claim I want the car to be stock.

And the original plan was to have 2 sets of wheels. I just didn't realise the Slipstreams were that cheap.

Is that noise a bit like a whistling kettle, then?

Mine's now from about 15mph upwards and it's getting like tinitus; it drives yer mad.

I'm sort of waiting to see what happens next; I have another diff adjacent to it (on garage floor) and I'm waiting for it to jump into place, since I've not really had opportunity to install it. And I've a sort of morbid curiosity about the old one self-destructing!

Kabooom! Sounds like you just want to tinker, and play with a new diff, Nick

Will stickier tyres put a greater load on the diff?

Nah, Kaboom's the noise an F20c makes when it lets go. I think it's more a Grrrrrrrddddddd.

But you're perfectly correct in principle!

Yes, when the torsen bit is doing its thing as there's less slip coming into play.
