Thanks for the advice, guys. I've never really understood how that procedure works before. I'm pretty sure my springs are very close in rate and certain about their length. (I got a bad set once. I check!) My chassis is probably a little tweaked and gets re-tweaked every time I smack into the boards. It still turns well both directions, in any case.
Bert, I applaud your continued enthusiasm with regard to the ECS drive axles. Do you own stock in the company? (j/k!) I won't be buying any until I've burned through the three sets of 3 Racing CVDs I'm using. I may have destroyed a set recently, due to over zealous use of a power tool when installing some tires. They're not likely the problem, anyway. This is a driving the car at 9/10ths suspension issue. I suspect my rear bearings or uprights may have too much play. This poor little car has seen a lot of action.
None of this matters right now, because this weekend is OVAL MINI MADNESS at Karz. There will be blood!
Thanks again!
