Bigger on the rear will make more difference on a front wheel drive car. But don't forget you have nothing on the rear at the moment, only the front is standard.
Personally I'd recommend an adjustable one, it's nice to adjust it to your own preference.
Is it possible/worthwhile to add an external RARB? I'm looking to fit one once my suspension is done as I'll be running lower but wonered about fitting a rear ARB to compensate.Slimy, we've been over this before. The LCR does have an anti-roll bar at the back, as do all of the beam-axle Golf Mk.4 derived cars. It's part of the rear beam and it's inside the beam section that connects the two trailing arms: impossible to get at or change. The LCR and other cars with the Sports suspension setup have a 21.7 mm bar, others have an 18mm bar.
