thanks greg, i'll try that. i think my over-all set-up is too stiff. it's close to the andy moore set-up, but i'm using 70wt front, 60wt losi in the rear with AE white(f) & AE pur(r) springs. i have 1.5mm pivot spacers 'cept with 1.875mm in the front-rear mount. but this year i'm gonna run "real" foams, instead of using gas foams on carpet. the X-rayT1 and the shuie didn't mind but the "4" hates 'em.
