Maybe 2" or so. Be carefull because the spring ends can get dangerously close to the inner sidewall. My mono leaf spring came with big washers and they were almost touching the sidewall after I put longer bolts on. I swapped it for a smaller diameter washer to give more clearence hard cornering when the tire flexs under.

:iagree: My 8" bolts were dangerously close to my tires too. Also, the move from 6" bolts to 8" bolts actually raised the rear of mine bout .5". I guess I have a super composite spring or sumpn. What kinda spring do you have?

:iagree: I just went thru this exercise last night.. 10'' bolts to replace the supplied bolts from the mono spring mfg..It did drop the rear by about
1 1/2'' , but the spring ends are very close to the inside of the tires. 3/8'' or so.. :skep: :skep:

After I changed to a smaller washer for the spring bushing I set the rear tire pressure to 30psi just to make em a little softer than my usual 40psi, then took the car for a test drive. I found a good sized empty parking lot where I could get up a little speed and raked the streering wheel back and forth in a sereis of hard s turns. My attempt was to flex the sidewalls in and try and see if contact was made with inner sidewall. Its easy to spot once it touches since it leaved a distinctive line mark on the tire. The smaller washer gave me enough extra room to feel safe about the whole thing and there was no contact from the agressive cornering.

don't know where grand prarie is but get a phone book for the nearest large town. most towns with any decent industry will have a store that caters to the industrial and manufacturing customer that specializes in fasteners (bolts). i went to a similar store and for >$10 i got two 1/2x10" bolts, jam nuts and 'nyloc' nuts. lowered the rear of the car about 1.5-2". the best part is, unlike the bolts marketed as lowering bolts, using jam nuts instead of cotter pins will allow you to fine tune your adjustment. i have about 1.5" of range to get the car to sit exactly how i want.
