Well...the Arrow has developed an issue where every once in awhile it will hike up one of the front tires during the launch. This will usually cause me to be way late or red. Last night this happened in the fourth round...my previous lights were .019,.001,.004 then in the third round the left tire went up and I was .064 I assume it's planting the right longer causing the late leave.

I have played with shock settings and tire pressure since it seemed at 6.5 lbs the car was wadding the tire up....I'm at 7.75 now. I also took one click out of the left shock and for the TT and first 3 rounds all seemed well. The shocks and springs are probably as old as half the members here so one or both could be the issue.

Any ideas?...I leave off the wood at 5600 so the car hits like a son of a itch. I don't have a two step and would rather not make that change since it seemed fine last year.

Maybe a heim sticking?.....HELP...this is killing me.

Make sure the mounts on the rearend are not bending at launch - check you heim joints - if it did not do it before something is moving. Could be a shock they do wear out at some point

Shock front...4 link....

I wonder if one of my limiters (cables ) is broken. It doesn't happen all the time though

Time to look it over very closely... look for cracked
welds, bent shocks(or oil on the shocks)... look at
both ends of the car, check your heims and give the
car a clean and lube job

Senior moment? maybe a Junior moment after all your older than dirt! By the way your new Race Car is done - when can I pick up the Challenger? I found the suit also.

Eric I forgot you still have your first communion money - no wonder Bob George whips on you - just open the wallet and let them dollar bills breath!
