Re: GTA ARB'S for my 156 Twinspark??
Well I did replace front and rear ARBs with GTA ones on my 147, but it is JTD...
Standard is 22mm front and 14mm rear, GTA is 23mm front and 16mm rear.
I cant really tell you what difference do GTA ARBs make, because I changed them along with Koni FSDs and Eibach ProKit. But compared to standard sport pack suspension body roll is greatly reduced with this setup...
