You can contact Simon at, Simon.Roberts@corneringforce.com. He's been a bit busy recently with some BTCC work.

Send him an email! I contacted them last week and got a prompt reply. My Öhlins dampers are already on their way to Harrogate for a revalve. We decided to revalve both front and rear to work with the kit, and springs will stay standard 350 lbs/in in the front and changed to 500 on the rear.

There is a photo of the rear ARB installed?? I would like to install it!

[techieboy]

Some of these might help. There's a few more here but those are the best pics.

The benefits of powder coated wishbones and a pressure washer. I was actually half way through cleaning up the remnants of the nearly 3 litres of oil that got spunked around the engine bay after a filter seal mishap (you can see the state of the underside of the gearbox in one of the pics) at the time.

Simon I thought my old car was clean underneath but not like yours. Steve

Mine rear arb is arrived,but not straightforward installation,droplinks on mine were replaced with cheaper drop links with ball and integral stud(like the standard on the front arb) not the inox spherical joint shown above,also missing the proper spacers to get the droplinks vertical for correct working position..... Now i need to make the spacers on the lathe

Have you given Simon a call? I'm sure he would sort it for you.

No, apart from this little problem(just a couple of minutes on a lathe) the rear ARB kit IMHO is the next biggest performance improvement for the suspension, really a no brainer option for serious handling after Nitron fitments,the way elise and derivatives should had done from day 1

Is this kit (ie both the front and rear ARB) really that good? How does it affect driving down bumpy country roads where you need lots of softness for the rotten tarmac - adversly at the expense of better smooth cornering on a track? Can you 'easily' adjust the rear ARB setting with the floorpan on ?

I believe Nev (not having tried, but looked into the kit alot myself) that its designed to offer a good balance between a compliant suspension set-up that is good on the road (that includes some poor roads), but still provide very good chassis control and stability. It also offers a large range of adjustment if you wish.

I think the rear ARB can be adjusted by removing the rear wheels only, although thats a more coarse adjustment which would recieve an initial set-up. The front ARB has both coarse and fine adjustments, so you only need to tweak the front in most scenarios to change to front / rear balance..

I set the CF NTRs to 12 clicks from hard on the road with the arb virually flat, which makes a lovely and suple ride. It rides better than any car i've been in. you can even stop avoiding the pot holes if you really like. with the front arb flat it is quite oversteery, but i like it that way.

on track, set the NTRs to 4 clicks from hard, and stiffen the front arb to 45 degrees (ish), thats hard as nails and makes for a more neutral set up, leaning towards a little understeer until the tyres are hot.

have never adjusted rear ARB which has always been on weakest setting. Have to remove undertray to adjust really. you could do it with a wheel off, but it would be a pita.

[JG]

Thats the front ARB adjustment with a 19mm spanner and can be done anytime, without removing wheels. just a bit of right lock.

When's the next group buy on these JG..?

Surely the track ARB setting will make much more sense for the road too?

[JG]

Well not really, stiffening up the front does make it very understeery (especially in the wet), and since you can't get heat into (nor should one really be trying to) the front tyres on the road, it doesn't make for the finest set-up for my liking. The 'My' is the key thing here. Thats the whole point in the system you can set it up for how you like to drive.

This is pretty good example (though I don't really condone this sort of behaviour )


With the ARB set stiffer you could induce a little understeer then and prevent all the oversteer with similar throttle/sterring input.
