Just got off the phone with DPM performance and I've order the White-line 24mm front and rear adjustable ARB's, on the basis that I should hopefully not only get a far more stable platform but if I'm foolish enough the rear should induce a bit more lift off when I feeling stupid.
Their also suitable with the rocco that I'll be changing to next year so it's a truck load of win on all accounts
do you have a ride impression to report? I'm curious about their swaybars too after looking at their WALK.
Overall I'm very impressed with the ARB's (only fitted the rear at the minute, saving the front for a rocco). Really tighten the car up, there's still roll but you'd have to be twat to get to that point anyway. It's currently on the medium setting (for the drop-links save) and it'll be staying there.
The ARB isn't without it problems. The plates in which mate with the drop-link are thicker than o.e. so require a longer bolt to compensate, White-line are aware of this and are doing nothing to rectify the issue which is crap, I haven't replaced it yet because there's no axial loads (very very minimal) only radial from the bar twisting so until it's up on some ramps then its staying like it.
I've had my Whiteline ARBs on for about 20k now - and am generally happy with them.
I hear what you say about the rear bar ends being thicker, and the long bolt needed. Mine is the same, but in all honestly, I've not had any issues with those, and I regularly remove the bar to re-grease the bushes. With the rear bar (any bar), the weakest link is the drop links - my original links gave up about 6weeks after fitting the WL ARB - new OEM drop links seem to be holding up - but I'm prepared for them to let go whenever.
Re the front WL bar - I have a very minor problem - on full lock, the ARB just kisses the steering track rods. It has worn the paint off the ARB, but not really damaged the actual metal of either. I'll just keep watching this.
The only real issue with the front bar - in general (applicable to all makes, not just Whiteline), is that they are a bit of a mare to fit, and an equal pain to re-grease the bushes.
For the record, my Whiteline bars are full hard rear, full soft front.
