After reading this post I put my fronts up to 38 psi for street driving and noticed a huge improvement. I was running 32 front and 28 rear and now 38 front and 32 rear. Awesome improvement in handling and much better grip from stand still. I wasn't sure whether it was advisable to run with higher pressure before I read this otherwise I would have done this sooner.
