Hey guys, i have a 1990 celica SX just purchased some second hand G4 racing coilovers that have only done 100kms picked the set up for 200$ (probably stolen) but my gain. ive had them fitted the fronts are fine nice and tight no rubbing no banging the rears however, when i hit a bump or pot hole make a really loud banging noise. but on some bumps there fine.. i think maybe the dampening is off, or not enough spring travel or no rebound im not sure ive never had coilovers before. it also rubs but i have no sway bar untill wednesday ive bought a whiteline 20mm bar with linkages so that will stop the side movement causing it to rub. How ever they didnt come with instructions, and i belive they are missing the little knobs to go on top of the strut to adjust stiffness. all that is there is a big nut and on top of the nut is a hex bolt, when i turn it, it spins the whole column can i still adjust stiffness or do i need those knobs? they are 26 way i believe aswell. I just need someone who may know how to adjust them and tell me how? i believe the base of the spring those to C spanner thingys have been fussed with, and the research ive done says NOT to touch those. so i need to know the heights they came with standard or even someone that has them let me know what theres is set at so i can get a nice ride in the rear any help would be sick. Ethan.
