[Fot] Fwd: racing the GT6.... tires or suspension?

Mon Oct 13 22:20:13 MDT 2008

I should have read the replies before answering--could have saved my  
breath--or at least my typing.

I do think that everyone tends to tie down the back end of production  
racears way too much. People are always shocked when i bounce up and  
down in Peyote's seat and the rear end bobs like a Galaxie with bad  
shocks. Keep them soft so they stick and then go up front and  
eliminate the understeer that a soft rear end causes. Of course the  
reason I say that is least understeer won't generally snap spin you in  
front of me.
