ARB’s

[Fatneck73]

Hi all

Hope you are staying safe.

With time on my hands...thinking of upgrading my arb’s. Everyone seems to recommend these.

Are they something I can fit at home?

Any suggestions on what ones to buy and where from?

Front - easy

Rear - tad challenging but can be diy’d with right tools (some patience and couple beers).

Good luck!

Ok ta...anyone know which ones are best AND where to order from? Every www I find in a lookup, then says ‘not for you car’.

From (foggy) memory, there are 2 "settings", check with MRC which way round.

hard on front, soft on rear rings a bell, but really can't remember, check!

The different bolt holes in the ends of the ARB's are used to adjust the amount of stiffness you require, the closer to the bar you go the stiffer the setting and the further away you go the softer the setting.



I asked MRC to set mine up as a stiffer Rear and softer Front (still stiffer than OEM) as that is generally accepted to promote a slightly increased oversteer feel which can slightly improve turn-in and slightly improve understeer, something the stock RS6 can really suffer from when pushing hard.

TBH the actual amount of improvement over OEM from "just" the ARB's is still relatively minor but noticeable, especially for everyday road use, but on the track when added to a slightly different driving 'technique' it becomes very noticeable how much understeer is removed (not all but most). Through a lot of trial and error I found that using what I'll call "trail acceleration", which is like trail braking but maintaining a constant tiny amount of throttle before you hit the apex (a really bad technique for most cars/bikes!) means that the Quattro system helps by pushing that newly stiffer rear around to help fight understeer. However it can/does lead to an understeer-oversteer-4 wheel drift-OMG I'M GOING TO DIE combo if done badly as I found out a few times on the track whilst figuring this out (I only use this on the track BTW as I just don't push that hard on the road).

Additionally the car will feel generally "stiffer" than before. My best description is that if you imagine the 3 original DRC settings on the MMI (Comfort - Dynamic - Sport) as stiffness settings 1-2-3 then after the thicker ARB's are fitted it feels like 1.5 - 2.5 - 3.5 instead, with each setting feeling a little stiffer than previous but still not a stiff as the next setting would before.

Hope that helps.

Brill. Cheers. Ordered.

I understand you need a 20mm spacer on front and to grind of casting or something??

Rear needs to be moved towards rear 6mm??

Does anyone have a few pics after fitting??
