I thought the later Golf like yours have 23mm front ARB and the early ones have a 21mm. Sem go and buy a rear whiteline ARB, you will not be disappointed. Whiteline provide very good after sales service.. I bought the front whiteline ARB from BalanceMotorsport, mention my name to Julian and the forum, he'll look after you..I need to order a rear ARB today and i'm not sure what to go for.
I'll be keeping the OEM Anniversary front ARB which I believe is 22mm.
So what size rear bar would work best with this, the options are a 22mm H&R or a 25mm Eibach.
I've got front fitted at the moment, need to order the rear ARB, do a search on forum. There's a few members with the rear ARB from whiteline. I think the whiteline rear ARB is only 22mm, its around ?123.50 inc last time I looked.Do you have the Whiteline?
I have to say the way it fits looks very strange [:S]
The first part of your statement is correct but the oversteer comment isn't. My V5 has a 23mm front bar as standard and understeered badly. Adding the Whiteline rear adjustable 22mm bar on medium-soft setting eliminated the understeer without causing oversteer. It's when you go for a thicker (i.e. stiffer) rear bar that you start getting oversteer. The 22mm Whiteline bar is roughly equivalent in stiffness to a 25mm Neuspeed bar because the Whiteline is shorter. Both Whiteline and Neuspeed bars are adjustable which means you can easily tune it to reduce/increase understeer or oversteer to achieve neutrality.From what I understand the MK4 benefits from a larger rear ARB so a 22R and 23F will cause oversteer.
I need this confirming though!
I think the R32 front bar is stiffer than the standard 21 or 23mm bars, so the thick 28mm Neuspeed is probably needed to give the right balance. With a standard front bar, I think a 28mm rear ARB may be too stiff and would cause excessive tail-happiness.I have a 23mm R32 front bar and 28mm Neuspeed rear ( Hardest setting) on mine.. rock solid! Sharp turn in and the rear feels glued..
