I agree, full solution will be to redo bushings, there are few models available. Well - leave me topics to cover here in this thread  |
You are correct that track enthusiasts do everything they can to eliminate rear steer, aka Weissach effect
for 964 a reduction comes from using the RS washers, but ultimately mono-balls are needed to eliminate it
the same happens in a 993, here there are 2 arms that control rear steer, the top rear and the rear of the A-arm, for 993 use the 993RS KT and A-arms which have stiffer rubber bushes these reduce rear steer similar to using the 964RS washers. And again the ultimate solution is t use all mono-balls
here's mine, using RSR A-arms which have mono-balls joints on both legs as opposed to only the leading leg stock and Rennline/Tarret arms for the other 3 arms
The main con is that all this hardware is expensive,
On track the RS setup is great it's only weakness is a tendency to lose alignment settings w/ hard use( the eccentric adjusters will rotate), The RSR w/ turnbuckle adjustment and locks at the eccentrics is the ultimate track solution
