Doesn't sound flangey too me, although it would be nice to hear your opinions on the driving side of ackerman. Iam guilty of copying your crossmember method, but that was because I was asked too. I already had a modded member on my car though, but only managed a relocation of 18mm doing it my way. The one I made to your style was all done for free though.
Iv driven with zero or very little ackerman all year last year, it takes some getting used to and is differant, but works fucking well FACT!! I did not hve one bit of understeer all year and one set of t1r's lasted me over 17 competition events where as the year befor (stock knuckles)i was understeering on track day tyres in the dry and went throgh two sets! Clarkey copied me 12 months after i done my subframe, tho my knucles are done to Clarkey/Polo msn late night chat spec Just to clear things up
