Hi all,

Looking for a but of advice, I've currently changed teams,driver,chassis,engine etc. No real drama with team,chassis,engine just struggling to find a consitent baseline setup now with the new driver being 240lbs or so, having usually worked with guys just over the 100lbs mark.

Car is a reasonably new spike, running on dirt, tracks are all about 1/4mile, from flat to medium banking, we run anywhere from soaking wet & slippery to fully blown away slick condition.

Currently running about 185lbs front springs, a .825lr & .800rr bars. Blocks I've tried between 2 3/4 to 3/1/2".

My question is do I run heavier rear bars to compensate for increase driver weight if so do I go 0.025 heavier or should it be 0.050?? Also change both or just LR or RR etc?? Do I run the bars I've been running & either block the car so it's higher in the rear to start with??Block the same with the same bars & add some turns in the rear to get it back to where it should be??? I'm struggling to find an answer that gives conistency. I have found that I need to run a couple PSI more pressure in the rear tyres otherwise they basically run flat, probably running abut 7-8 in LR & about 12-16 in the RR.

Any help greatly appreciated, as I know the whole combination when it all works together will be good.
